WELCOME
Thank you for choosing the ADDERLink® INFINITY 1100 and INFINITY 2100 (aka
ALIF1100 and ALIF2100) high performance extenders.The range offers dual-head
video, audio and USB delivered over fiber and/or CATx connections. Pixel-
perfect color, accurate picture quality at up to 2560×1600@60Hz and USB2.0
with fast switching.
Product in brief · Support for dual link speeds up to 1GbE using either CATx
and/or fiber. Several model
variants available:
· ALIF1102 models have a fixed 1GbE CATx port plus an SFP socket for
additional CATx or fiber.They also have a single DisplayPortTM video
connector,
· ALIF1104 transmitters have a fixed 1GbE CATx port plus an SFP socket for
additional CATx or fiber.They also have a single HDMI® video connectors,
· ALIF2102 models have a fixed 1GbE CATx port plus an SFP socket for
additional CATx or fiber.They also have two DisplayPortTM video connectors,
· ALIF2122 models have two SFP sockets for CATx or fiber.They also have two
DisplayPortTM video connectors,
· ALIF2124 transmitters have two SFP sockets for CATx or fiber.They also have

· Uni-directional analog audio (with combined headset jack on the receiver),
· Adder’s USB True Emulation for fast switching,
· Support for advance diagnostic and troubleshooting tools,
· Backwards compatibility with existing ALIF range,
· Plug and play.
Linking
ALIF1100 and ALIF2100 units can be linked in two mains ways: Direct or
Networked.
Direct linking Where transmitters and receivers are directly linked to each
other, very little configuration action is required, provided that they both
have their factory default settings in place – just link them together. If the
standard settings have been changed in a previous installation, you merely
need to perform a manual factory reset on each unit.
Networked linking Where units are connected via networked links, you can
either configure them individually, or configure them collectively using an
AIM server: · Configuring networked ALIF units individually – In the absence
of an AIM server,
unallocated units have the ability to locate each other.You can alter settings
via the OSD on the console connected to the RX unit by pressing CTRL + ALT +
C. · Configuring networked ALIF units collectively – The ADDERLink® INFINITY
Management (AIM) server allows you to configure, control and coordinate any
number of ALIF transmitters and receivers from a single application.
Note: If you are using one or more transmitters within an installation managed
by an AIM server, the AIM server must be running firmware version 5.3 or
above.
Safety
Please refer to the safety booklet provided in the box before use of this
product.
IMPORTANT:When using AIM to configure ALIF
units, it is vital that all units that you wish to locate and control are set
to their factory default settings. Otherwise they will not be located by the
AIM server. If necessary, perform a manual factory reset on each ALIF unit.

INSTALLATION
LOCAL FEED THROUGH
ALIF receiver units can be configured to support a local link to a separate
host PC, via a dedicated ALIF transmitter, in addition to the main link to the
network.The locally linked PC remains completely isolated from the main
network. To configure this arrangement, ensure that the receiver is using its
default IP address and is directly connected to the transmitter.The
transmitter must use its primary network port, which is the interface using
169.254.1.33 as its default address, and be configured to either “Auto” or
“Allow” for insecure connections (see “Insecure connections” on page 44).The
easiest way to do this is to use a factory new or factory reset transmitter,
you can then change any additional settings after connecting it to the
receiver. Notes: For the local feed through feature to operate, the AIM server
must be at version 4.8 or greater while the endpoints must be at version 4.0
or greater.The TX must use its primary network port and be in it’s default
configuration, which can be achieved via a new unit or a factory refresh, when
connected to the RX.
ALIF2122 RX
Note: ALIF1102 RX units support a single display.

FURTHER INFORMATION
In operation, the user of the console at the ALIF receiver can use the
following hotkey combination
to toggle between the network and local links: To change from a network link
to the local link:
enter CTRL+ALT+L To change from the local link to a network link:
enter CTRL+ALT +C to display the OSD and choose
the required connection. Note:The L and C default hotkeys can be changed

TX/RX high speed links
ALIF2100 and ALIF1100 units can be either connected directly to each other or
via a high speed (up to 1GbE) network. Links can be made: · Using the in-built
CATx ports on ALIF2102,ALIF1102 & ALIF1104 models (see below), · Using
additional CATx connections within the SFP ports (see next page), · Using the
SFP ports with optional fiber (FCoE) modules (see next page).
Teaming ALIF2100 and ALIF1100 units are ready to automatically invoke teaming
whenever the CATx and SFP (with either CATx or fiber modules installed) ports
are both used to link transmitters and receivers.Teaming potentially doubles
the available bandwidth for video intensive applications and also provides
redundancy in case one link is lost.
Optional SFP module types · SFP-CATX-RJ45 for use with CAT5e (and above) cable. · SFP-SM-LC modules require OS1 or OS2 single mode fiber. · SFP-MM-LC modules require OM1, OM2, OM3 or OM4 multi-mode fiber. See Appendix E for further details about SFP modules and cable lengths.
To link using the in-built CATx port
(ALIF2102, ALIF1102 & ALIF1104
models only) 1 Insert a suitable CATx cable into the
RJ45 port on the front panel of the TX unit.

Configuration
ALIF CONFIGURATION VIA WEB PAGES
Each ALIF unit hosts its own internal set of web pages which contain all
configuration details and settings (see also Start of Life, shown right).You
will need to use a computer connected to the same network as each ALIF unit to
access the web pages. Additionally, on the console attached to the ALIF RX
unit, you can access its configuration details via the On Screen Display (OSD)
by pressing CTRL + ALT + C (or by tapping the icon on the touchscreen) – see
page 29.
To manually configure ALIF units via their web pages Run a web browser on your
computer and enter the IP address of the required ALIF unit:
The default addresses (if using port 1) are TX: https://169.254.1.33 RX:
https://169.254.1.32
The default addresses (if using port 2) are TX: https://169.254.1.43 RX:
https://169.254.1.42
The opening page should be displayed:
Start of Life:AIM or Point to Point configuration
To streamline initial configuration processes, all ALIF units employ a Start
of Life (SoL) procedure when they are in an unconfigured state; either because
they are new or because they have undergone a factory reset.
When an unconfigured ALIF unit boots, its SoL procedure will guide it to
automatically determine which of two modes it should adopt:
· AIM mode – place itself into the control of a specific AIM server on the
network, whereupon the ALIF will be assigned suitable configuration details to
fit within the network of similar units.
· Mini Matrix (P2P) mode – place itself into Mini Matrix (Point to Point) mode
to allow manual configuration of links with other ALIF units.
The SoL procedure follows this basic logic flow to determine the correct mode:

PERFORMING A MANUAL FACTORY RESET
A factory reset returns ALIF unit to its default configuration.
To perform a manual factory reset 1 Power on the ALIF unit.
2 Use a long narrow implement (e.g. a straightened-out paper clip) to press-
andhold the recessed reset button on the front panel for roughly ten seconds,
until the status indicator turns blue (Note: alternating red/green indications
will occur during the ten second period while the button is still pressed).
3 Release the reset switch.The indicator will change to red for a short while
(less than ten seconds) and then back to blue while ALIF unit performs the
reset and should then change to an alternative color, usually orange
initially, signifying that the operation is complete.
Note: If you are performing a factory reset and intend to disconnect the power
immediately after the reset, you must wait at least 30 seconds after you have
released the reset button for it to complete the process.

Once the mode has been set to AIM control, an ALIF will remain operating that way until it undergoes a factory reset. If set to Matrix Mode (P2P), an ALIF will remain thus until it undergoes a factory reset or is discovered by an AIM server.
Note:When the modules enter Mini Matrix mode, you can cancel auto-SoL at any point by pressing Ctrl-Alt-C.

PLACING THE DEVICE INTO RECOVERY MODE
Recovery mode may allow an ALIF unit to be diagnosed or upgraded in the event
of the main mode being non-operational. To boot the device into recovery mode
1 Power on the ALIF unit. 2 Use a long narrow implement (e.g. a
straightened-out paper clip) to press-and-hold the recessed reset button on
the front panel (for less than ten seconds) until the status indicator starts
alternating red/green. Note: A solid blue indication will occur after the ten
second period. 3 Release the reset switch.The indicator will change to red for
a short while (less than ten seconds) and then alternating red/green
signifying that the device is in recovery mode. Note: If the indicator turns
blue, then a factory reset has been performed instead, the device will not be
in recovery mode and the operation will need to be attempted again.

CONFIGURING DUAL TOUCHSCREENS
When a single touchscreen is used with an ALIF RX, it should operate correctly
as soon as the USB link is made between the screen and the ALIF RX. However,
if two touchscreens are installed it may be necessary to instruct the ALIF RX
which screen to correctly attribute to each USB input.
To attribute dual touchscreens 1 Access the Configuration pages on the ALIF RX – see page 29.
2 Click the Ports entry from the list of pages on the left side.

CREATING AN UNMANAGED MATRIX
Although ALIF units are most often organised and managed by a central AIM
server, it is possible to create small networks of ALIF units, most often in
matrix arrangements, ie multiple TX and RX units which can freely cross-
connect.
INSTALLATION
CONFIGURATION
OPERATION
FURTHER INFORMATION
This method of connection works well for small numbers of TX and RX units, but
will become more difficult to manage as more units are attached.The maximum
number of TX sources that can be made available to any RX is sixteen.
To create an unmanaged matrix 1 Connect ALIF TX and RX units (with their
various hosts and peripherals) to a suitable
switch, as described in the Installation section – see page 12.
Note:ALIF4000 modules can also be mixed within the same matrix.
Note: If any device was previously managed by AIM, then it will need to be
given a factory reset before continuing with this procedure.There must not be
an AIM connected on the matrix network otherwise, when such devices undergo a
factory reset, they will automatically revert to AIM control.
You now need to perform the following procedure on each ALIF RX in turn:
2 Access the Configuration pages – see page 29.
3 Click the Transmitters option from the list on the left side.This page will
list all of the available TX units which are not under AIM control. See page
41.
4 Click the Presets option from the list on the left side. Use this page to
add each TX unit to the list of presets for the RX that you are editing. See
page 36.
To use the matrix · On each RX, use the OSD to access the required TX units in
the usual manner.

channel stereo but the incoming stream is 6 channels, turning this off may
allow L & R audio output to work – if the attached device can cope, but other
channels will be lost (ie. there is no down-mix support).
USB Ports This page provides basic information about the USB ports numbered 1
to 4 inclusive, located on the RX unit. Type – Identifies the type of the USB
port. Port 1 on the front of the RX is Transparent, 2-3 on the front, 4-5 on
the back are the Emulated ports. Enabled – Confirms whether the USB ports are
enabled or disabled. HID Only – (For emulated USB ports only) When ticked, all
ports are limited to supporting Human Interface Devices only, such as
keyboards and mice. Disable Mass Storage – When ticked, this option prevents
the use of USB mass storage devices on the receiver unit.This could be useful
in situations where smart card readers need to be used for security purposes
but the use of USB drives need to be prevented. Security – (For emulated USB
ports only) Controls whether USB data is encrypted. On forces always on, Off
forces always off and Prefer off will be off unless the TX requests it.

network.
IP Address – This shows the IP address in use, which can be obtained via DHCP,
a static IP or a link local (zero-config).
Netmask – The netmask of this network interface.The device can function in a
network zero-config state which does not require the setting of a static
netmask.
Gateway – The gateway address of this network interface.The device can
function in a network zero-config state which does not require the setting of
a static gateway.
Static IP Address – When the DHCP enabled’ option (below) is unchecked, click on
Edit’ to enter/edit a static IP Address, Netmask and Gateway for the unit.
DHCP Enabled – When ticked, the corresponding port will derive its IP Address,
Netmask and Gateway details from the DHCP server listed in the field below.

Networks – When ticked, the ALIF1100 / ALIF2100 receiver will treat its two
main network ports as independent routes to the transmitter(s) and not attempt
to find secondary cross connections, which may not be possible due to the
network topology.This setting will have no effect when ALIF1100 / ALIF2100
receivers link with ALIF1100 / ALIF2100 or ALIF4000 transmitters due to their
use of auto discovery. However, when an ALIF1100 / ALIF2100 receiver links
with other dual port ALIF transmitters (such as an ALIF2002T), enabling this
option can prevent unnecessary delays due to the time taken looking for routes
that are effectively network dead ends. Route of Last Resort – In a multi-
interface device such as this, the interface which is ticked will be used as
the default whenever it is unclear which interface should be used for network
traffic.

Video Ports This page provides basic information about the two video ports
located on the TX unit.
Enabled – Confirms whether each video port is enabled or disabled. Connected –
Confirms whether functioning host video drivers are connected to the two video
ports.
EDID Source – Lists the EDID mode currently being output on the two video
connectors.An option called Saved attached monitor is available and will save
that first RX’s EDID in persistent storage and use that EDID forever
(including over reboot, powercycle, etc) until it is cleared (see below) or a
Fixed EDID is selected instead.
To save a monitor EDID and use it for that given video and/or audio port,
select the Saved Attached Monitor option. The current Attached monitor EDID
will be saved in persistent storage on the TX and used from now on by the TX
until is it cleared (see below).
To clear the saved monitor EDID, either: · Factory reset the TX · Select
“Attached Monitor” EDID on both the video and audio EDID
Source settings for the same physical DP port. For more information about how
video and audio EDID data are derived, see Support for analog and digital
audio. Note: Fixed EDIDs were updated in v3.00 to add support for higher frame
rates at each fixed EDID resolution.The default frame rate remains as given in
the fixed EDID name (eg. 60), however, HD and higher resolutions will include
higher rates which are supported at those resolutions. eg. 240Hz for
1920x1080p60.
Dynamic Range – This option is shown only when a fixed EDID is selected.These
settings are fixed at SDR8 (8bpc) for this model.
Attached Monitor Receiver – If the Attached monitor’ option has been selected as the
EDID Source’, then this displays the name of the RX device that
supplied the EDID currently being used.
EDID Optimization – When ticked, and if the EDID source option is set to
`Attached monitor’; upon connecting with a new receiver, the transmitter will
compare the preferred video mode of the new monitor with the current video
output from the host PC. Only if they differ will the transmitter present the
new monitor’s EDID to the host PC.This option speeds up switching as the host
PCs graphics card does not have to go through a hotplug detect routine each
time a new receiver is connected. If this setting is unticked, the transmitter
will always present a new EDID to the host PC.
Background Refresh (frames) – The system will send all changing video as soon
as it changes. In addition, it is possible to send unchanging video in the
background, to overcome problems of lost network traffic. This control will
configure how often a whole frame of video will be sent alongside changing
video. In situations of frequently changing video, or high reliability
networks, this value can be set to a higher number, or even set to disabled.
Compression Type – Allows you to select the compression method to best suit
the nature of the video sources. Settings are: Pixel Perfect, Adaptive,
Smoothest Video or Advanced (which allows you to set the maximum and minimum
compression levels).
Frame Skipping – Frame Skipping involves `missing out’ video frames between
those captured by the TX unit. For video sources that update only infrequently
or for those that update very frequently but where high fidelity is not
required, frame skipping is a good strategy for reducing the overall bandwidth
consumed by the system. Range: 0 to 100%.
Magic Eye – When ticked, this feature increases performance and reduces
network traffic if ALIF units are used with host computers that have dithered
video output. It also improves performance if the video source is noisy.
Max Bits per Pixel – These settings are fixed at 24bpp (ie, 8bpc) for this
model.
Multicast Addresses – This section lists all video multicast IP addresses that
have been configured. Setting the field to a blank (empty string) value will
cause the system to automatically generate a default multicast address.

USB Ports This page provides basic information about the USB ports located on
the
TX unit.
Type – Identifies the type of the USB port.
Enabled – Confirms whether the USB ports are enabled or disabled.
Connected – Confirms whether valid devices are connected to either USB port.
Note:As both USB ports share the same physical port, it is not possible to
detect whether a specific port has a device connected.
Rate Limit – This option allows you to place an upper limit on the bandwidth
that can be consumed by the transparent USB subsystem as a whole.This can be
useful in situations where the overall network bandwidth is quite low and high
resolution video performance is being impacted by USB operation; particularly
during large file transfers to or from a mass storage device inserted into the
ALIF receiver. Using this option you can choose an appropriate USB bandwidth
rate limit between 1 and 480Mbps.
Reserved Ports – Allows USB ports to be optionally reserved for use with
particular devices. Once reserved, certain rules can be applied to them via
the AdderLink Infinity Manager (AIM) application.
Present Boot Keyboard – When ticked, the TX unit will report a virtual dummy
boot keyboard to the attached PC to ensure that a keyboard is always reported
when the PC boots up.The dummy boot keyboard uses one of the 13 USB endpoints,
therefore if all 13 endpoints are required elsewhere for USB devices (or a KVM
switch only supports two HID devices) then it can be disabled by deselecting
this option.
Max Hub Size – Using this option you can select whether the TX unit should
report itself as a 13 or a 7 port USB hub. Some USB hosts are only able to
support 7 port USB hubs. If this option is set to 7, then only 7 USB devices
are supported by the PC.
Security – Controls whether USB data is encrypted. On forces always on, Off
forces always off and Prefer off will be off unless the RX requests
it.
Serial Port This page provides basic information about the serial option port
located available on the AUX USB port located on the front panel of the TX
unit.
Enabled – Confirms whether the serial port is enabled or disabled. Speed – The
`baud rate’ of the serial device.
Data Bits – The number of data bits to be used (5, 6, 7, or 8). Stop Bits –
The number of stop bits to be used (1 or 2). Parity – The parity checking to

APPENDIX B – Support for analog and digital audio
The ALIF1100 and 2100 ranges benefit from multiple audio signal streams: ·
Uni-directional analog audio – from the host PCs jack socket, · Uni-
directional digital audio – via the video connection, · Bi-directional digital
audio – via the USB connection (converted to/from analog). Even though the
analog and digital outputs from a particular host PC might be carrying signals
that originated from the same audio source, they are handled separately
throughout the ALIF system and can never be mixed. For digital audio derived
from the video connection, the host PC needs to know details of the required
signal to send out, eg 16 or 24-bit, 48, 88.2 or 96kHz sample rate, etc, so a
valid definition of the requirement must be sent to the host PC.This is done
as an audio sub-set of the EDID definition that is used to declare the video
display capabilities/ requirements. In the diagram below the display and
speaker installation send their video and digital audio portions of the EDID
(Extended Display Identification Data) definition via the ALIF2100 receiver
and transmitter to the host PC:
In response, the host PC begins sending video and audio signals that are
appropriate for the receiving peripherals:
This presents an issue for the host PC and its ALIF transmitter as they must now respond to separate EDID definitions from the video display on one receiver (which will probably also have its own EDID audio sub-set) and the EDID definition from the digital audio device on the other receiver:
To solve potential conflicts, the ALIF transmitter uses a set of rules to
determine how it mixes different EDID definitions. Firstly, for any connected
video or digital audio devices, the ALIF system can consider each one using
any of three selectable states:
· Attached – ALIF will interrogate the attached video/audio device to
ascertain its exact capabilities/requirements.
· Fixed – ALIF will use a fixed definition (e.g 1920x1080p60 and 2-channel
audio) to represent the video/audio device(s).
· None – No representation will be made for the device.
The above states are then combined by the ALIF1100/2100 transmitter, as
connections are made to the different devices, using the following rules:
Video EDID Audio EDID

FURTHER INFORMATION
In the above case, the video and digital audio from the host PC are both sent to the same receiver. However, the flexibility of the ALIF system is such that peripherals and hosts can be mixed as required. For instance, the video feed could be sent to one receiver, while the digital audio is used by a set of speakers on a different receiver:

Merge the video and audio EDID definitions. Send video EDID definition only.
Use whichever EDID definition is available first.
Wait for the Attached device to declare and then use its data to modify those
of the Fixed device. Note:The video EDID retains precedence for setting
general items, such as serial no., manufacturer, etc.
Note:The analog audio is switched entirely separately to the digital audio feed.

APPENDIX C – Tips for success when networking ALIF units
ALIF units use multiple strategies to minimize the amount of data that they
send across networks. However, data overheads can be quite high, particularly
when very high resolution video is being transferred, so it is important to
take steps to maximize network efficiency and help minimize data output.The
tips given in this section have been proven to produce very beneficial
results.
Summary of steps · Choose the right kind of switch.
· Create an efficient network layout.
· Configure the switches and devices correctly.
Choosing the right switch Layer 2 switches are what bind all of the hosts
together in the subnet. However, they are all not created equally, so choose
carefully. In particular look for the following:
· 10Gigabit ports,
· Support for IGMP v2 (or v3) snooping,
· Support for Jumbo frames up to 9216-byte size,
· High bandwidth connections between switches, preferably Fiber Channel.
· Look for switches that perform their most onerous tasks (e.g. IGMP snooping)
using multiple dedicated processors (ASICS).
· Ensure the maximum number of concurrent `snoopable groups’ the switch can
handle meets or exceeds the number of ALIF transmitters that will be used to
create multicast groups.
· Check the throughput of the switch: Full duplex, 10Gbps up- and down- stream
speeds per port.
· Use the same switch make and model throughout a single subnet.
· You also need a Layer 3 switch. Ensure that it can operate efficiently as an
IGMP Querier.
Creating an efficient network layout Network layout is vital.The use of IGMP
snooping also introduces certain constraints, so take heed:
· Keep it flat. Use a basic line-cascade structure rather than a pyramid or
tree arrangement.
· Keep the distances between the switches as short as possible.
· Ensure sufficient bandwidth between switches to eliminate bottlenecks.
· Where the AIM server is used to administer multiple ALIF transceivers,
ensure the AIM server and all ALIF units reside in the same subnet.
· Do not use VGA to DisplayPortTM converters, instead replace VGA video cards
in older systems with suitable DisplayPortTM replacements. Converters cause
ALIF TX units to massively increase data output.
· Wherever possible, create a private network.
The recommended layout The layout shown below has been found to provide the
most efficient network layout for rapid throughput when using IGMP snooping:
· Use no more than two cascade levels. · Ensure high bandwidth between the two
L2 switches and very high bandwidth between
the top L2 and the L3.Typically 10GB and 20GB, respectively for 48 port L2
switches.

Configuring the switches and devices The layout is vital but so too is the
configuration: · Enable IGMP Snooping on all L2 switches. · Ensure that IGMP
Fast-Leave is enabled on all switches with ALIF units connected
directly to them. · Enable the L3 switch as an IGMP Querier. · Enable Spanning
Tree Protocol (STP) on all switches and importantly also enable
portfast (only) on all switch ports that have ALIF units connected. · If any
hosts will use any video resolutions using 2048 horizontal pixels (e.g. 2048 x
1152, 2048 x 2048), ensure that Jumbo Frames are enabled on all switches. ·
Choose an appropriate forwarding mode on all switches. Use Cut-through if
available,
otherwise Store and forward. · Optimize the settings on the ALIF transmitters:
· If moving video images are being shown frequently, then leave Frame Skipping
at a low percentage and instead reduce the Peak bandwidth limiter.
· Where screens are quite static, try increasing the Background Refresh
interval and/ or increasing the Frame skipping percentage setting.
Make changes to the ALIF transmitters one at a time, in small steps, and view
typical video images so that you can attribute positive or negative results to
the appropriate control.
· Ensure that all ALIF units are fully updated to the latest firmware version
(at least v2.1).

APPENDIX D – Troubleshooting
Problem: The video image of the ALIF receiver shows horizontal lines across
the screen.
This issue is known as Blinding because the resulting video image looks as
though you’re viewing it through a venetian blind.
When video is transmitted by ALIF units, the various lines of each screen are
divided up and transmitted as separate data packets. If the reception of those
packets is disturbed, then blinding is caused.The lines are displayed in place
of the missing video data packets.
There are several possible causes for the loss of data packets:
· Incorrect switch configuration.The problem could be caused by multicast
flooding, which causes unnecessary network traffic.This is what IGMP snooping
is designed to combat, however, there can be numerous causes of the flooding.
· Speed/memory bandwidth issues within one or more switches.The speed and
capabilities of different switch models varies greatly. If a switch cannot
maintain pace with the quantity of data being sent through it, then it will
inevitably start dropping packets.
· One or more ALIF units may be outputting Jumbo frames due to the video
resolution (2048 horizontal pixels) being used. If Jumbo frames are output by
an ALIF unit, but the network switches have not been configured to use jumbo
frames, the switches will attempt to break the large packets down into
standard packets.This process introduces a certain latency and could be a
cause for dropped packets.
Remedies: · Ensure that IGMP snooping is enabled on all switches within the
subnet. · Where each ALIF unit is connected as the sole device on a port
connection to
a switch, enable IGMP Fast-Leave (aka Immediate Leave) to reduce unnecessary
processing on each switch. · Check the video resolution(s) being fed into the
ALIF transmitters. If resolutions using 2048 horizontal pixels are unavoidable
then ensure that Jumbo frames are enabled on all switches. · Check the
forwarding mode on the switches. If Store and forward is being used, try
selecting Cut-through as this mode causes reduced latency on lesser switch
designs. · Ensure that one device within the subnet is correctly configured as
an IGMP Querier, usually a layer 3 switch or multicast router. · Try adjusting
the transmitter settings on each ALIF to make the output data stream as
efficient as possible. See ALIF transmitter video settings for details.

Problem:The audio output of the ALIF receiver sounds like a scratched record.
This issue is called Audio crackle and is a symptom of the same problem that
produces blinding (see previous page).The issue is related to missing data
packets. Remedies: As per blinding discussed previously.
Problem: AIM cannot locate working ALIF units. There are a few possible
causes: · The ALIF units must be reset back to their zero config IP addresses
for AIM discovery.
If you have a working network of ALIF’s without AIM and then add AIM to the
network, AIM will not discover the ALIFs until they are reset to the zero
config IP addresses. · This could be caused by Layer 2 Cisco switches that
have Spanning Tree Protocol (STP) enabled but do not also have portfast
enabled on the ports to which ALIF units are connected.Without portfast
enabled,ALIF units will all be assigned the same zero config IP address at
reboot and AIM will only acquire them one at a time on a random basis. You can
easily tell whether portfast is enabled on a switch that is running STP: When
you plug the link cable from a working ALIF unit into the switch port, check
how long it takes for the port indicator to change from orange to green. If it
takes roughly one second, portfast is on; if it takes roughly thirty seconds
then portfast is disabled. Remedies: · Ensure that the ALIF units and the AIM
server are located within the same subnet because AIM cannot cross subnet
boundaries. · Manually reset the ALIF units to their zero config IP addresses.
· Enable portfast on all switch ports that have ALIF units attached to them or
try temporarily disabling STP on the switches while AIM is attempting to
locate ALIF units.

APPENDIX E – Glossary
Internet Group Management Protocol Where an ALIF transmitter is required to
stream video to two or more receivers, multicasting is the method used.
Multicasting involves the delivery of identical data to multiple receivers
simultaneously without the need to maintain individual links.When multicast
data packets enter a subnet, the natural reaction of the switches that bind
all the hosts together within the subnet, is to spread the multicast data to
all of their ports.This is referred to as Multicast flooding and means that
the hosts (or at least their network interfaces) are required to process
plenty of data that they didn’t request. IGMP offers a partial solution.
The Internet Group Management Protocol (IGMP) is designed to prevent multicast
flooding by allowing Layer 3 switches to check whether host computers within
their care are interested in receiving particular multicast transmissions.They
can then direct multicast data only to those points that require it and can
shut off a multicast stream if the subnet has no recipients.
There are currently three IGMP versions: 1, 2 and 3, with each version
building upon the capabilities of the previous one:
· IGMPv1 allows host computers to opt into a multicast transmission using a
Join Group message; it is then incumbent on the router to discover when they
no longer wish to receive; this is achieved by polling them (see IGMP Querier
below) until they no longer respond.
· IGMPv2 includes the means for hosts to opt out as well as in, using a Leave
Group message.
· IGMPv3 encompasses the abilities of versions 1 and 2 but also adds the
ability for hosts to specify particular sources of multicast data.
ADDERLinkTM INFINITY units make use of IGMPv2 when performing multicasts to
ensure that no unnecessary congestion is caused.
IGMP Snooping The IGMP messages are effective but only operate at layer 2 –
intended for routers to determine whether multicast data should enter a
subnet. A relatively recent development has taken place within the switches
that glue together all of the hosts within each subnet: IGMP Snooping. IGMP
snooping means these layer 2 devices now have the ability to take a peek at
the IGMP messages. As a result, the switches can then determine exactly which
of their own hosts have requested to receive a multicast and only pass on
multicast data to those hosts.
IGMP Querier When IGMP is used, each subnet requires one Layer 3 switch to act
as a Querier. In this lead role, the switch periodically sends out IGMP Query
messages and in response all hosts report which multicast streams they wish to
receive.The Querier device and all snooping Layer 2 switches then update their
lists accordingly (the lists are also updated when Join Group and Leave Group
(IGMPv2) messages are received).
IGMP Fast-Leave (aka Immediate Leave) When a device/host no longer wishes to
receive a multicast transmission, it can issue an IGMP Leave Group message as
mentioned above.This causes the switch to issue an IGMP Group-Specific Query
message on the port (that the Leave Group was received on) to check no other
receivers exist on that connection that wish to remain a part of the
multicast.This process has a cost in terms of switch processor activity and
time.
Where ALIF units are connected directly to the switch (with no other devices
on the same port) then enabling IGMP Fast-Leave mode means that switches can
immediately remove receivers without going through a full checking
procedure.Where multiple units are regularly joining and leaving multicasts,
this can speed up performance considerably.
Jumbo frames (Jumbo packets) Since its commercial introduction in 1980, the
Ethernet standard has been successfully extended and adapted to keep pace with
the ever improving capabilities of computer systems.The achievable data rates,
for instance, have risen in ten-fold leaps from the original 10Mbit/s to a
current maximum of 100Gbit/s.
While data speeds have increased massively, the standard defining the number
of bytes (known as the Payload) placed into each data packet has remained
resolutely stuck at its original level of 1500 bytes.This standard was set
during the original speed era (10Mbits/s) and offered the best compromise at
that speed between the time taken to process each packet and the time required
to resend faulty packets due to transmission errors.
But now networks are much faster and files/data streams are much larger; so
time for a change? Unfortunately, a wholesale change to the packet size is not
straightforward as it is a fundamental standard and changing it would mean a
loss of backward compatibility with older systems.
Larger payload options have been around for a while, however, they have often
been vendor specific and at present they remain outside the official
standard.There is, however, increased consensus on an optional `Jumbo’ payload
size of 9000 bytes and this is fully supported by the ADDERLinkTM INFINITY
(ALIF) units.
Jumbo frames (or Jumbo packets) offer advantages for ALIF units when
transmitting certain high resolution video signals across a network.This is
because the increased data in each packet reduces the number of packets that
need to be transferred and dealt with – thus reducing latency times.
The main problem is that for jumbo frames to be possible on a network, all of
the devices on the network must support them.

Spanning Tree Protocol (STP) In order to build a robust network, it is
necessary to include certain levels of redundancy within the interconnections
between switches.This will help to ensure that a failure of one link does not
lead to a
complete failure of the whole network.
The danger of multiple links is that data packets, especially multicast
packets, become involved in continual loops as neighbouring switches use the
duplicated links to send and resend them to each other.
To prevent such bridging loops from occurring, the Spanning Tree Protocol
(STP), operating at layer 2, is used within each switch. STP encourages all
switches to communicate and learn about each other. It prevents bridging loops
by blocking newly discovered links until it can discover the nature of the
link: is it a new host or a new switch?
The problem with this is that the discovery process can take up to 50 seconds
before the block is lifted, causing problematic timeouts.
The answer to this issue is to enable the portfast variable for all host links
on a switch.This will cause any new connection to go immediately into
forwarding mode. However, take particular care not to enable portfast on any
switch to switch connections as this will result in bridging loops.
Forwarding modes In essence, the job of a layer 2 switch is to transfer as
fast as possible, data packets arriving at one port out to another port as
determined by the destination address. This is known as data forwarding and
most switches offer a choice of methods to achieve this. Choosing the most
appropriate forwarding method can often have a sizeable impact on the overall
speed of switching:
· Store and forward is the original method and requires the switch to save
each entire data packet to buffer memory, run an error check and then forward
if no error is found (or otherwise discard it).
· Cut-through was developed to address the latency issues suffered by some
store and forward switches. The switch begins interpreting each data packet as
it arrives. Once the initial addressing information has been read, the switch
immediately begins forwarding the data packet while the remainder is still
arriving. Once all of the packet has been received, an error check is
performed and, if necessary, the packet is tagged as being in error.This
checking `on-the-fly’ means that cut-through switches cannot discard faulty
packets themselves. However, on receipt of the marked packet, a host will
carry out the discard process.
· Fragment-free is a hybrid of the above two methods. It waits until the first
64 bits have been received before beginning to forward each data packet.This
way the switch is more likely to locate and discard faulty packets that are
fragmented due to collisions with other data packets.
· Adaptive switches automatically choose between the above methods. Usually
they start out as a cut-through switches and change to store and forward or
fragmentfree methods if large number of errors or collisions are
detected.
So which one to choose? The Cut-through method has the least latency so is
usually the best to use with ADDERLinkTM INFINITY units. However, if the
network components and/or cabling generate a lot of errors, the Store and
forward method should probably be used. On higher end store and forward
switches, latency is rarely an issue.
Layer 2 and Layer 3:The OSI model When discussing network switches, the terms
Layer 2 and Layer 3 are very often used.These refer to parts of the Open
System Interconnection (OSI) model, a standardized way to categorize the
necessary functions of any standard network. There are seven layers in the OSI
model and these define the steps needed to get the data created by you
(imagine that you are Layer 8) reliably down onto the transmission medium (the
cable, optical fiber, radio wave, etc.) that carries the data to another user;
to complete the picture, consider the transmission medium is Layer 0. In
general, think of the functions carried out by the layers at the top as being
complex, becoming less complex as you go lower down.
As your data travel down from you towards the transmission medium (the cable),
they are successively encapsulated at each layer within a new wrapper (along
with a few instructions), ready for transport. Once transmission has been made
to the intended destination, the reverse occurs: Each wrapper is stripped away
and the instructions examined until finally only the original data are left.
So why are Layer 2 and Layer 3 of particular importance when discussing
ADDERLinkTM INFINITY? Because the successful transmission of data relies upon
fast and reliable passage through network switches and most of these operate
at either Layer 2 or Layer 3. The job of any network switch is to receive each
incoming network packet, strip away only the first few wrappers to discover
the intended destination then rewrap the packet and send it in the correct
direction.

In simplified terms, the wrapper that is added at Layer 2 (by the sending
system) includes the physical address of the intended recipient system, i.e.
the unique MAC address (for example, 09:f8:33:d7:66:12) that is assigned to
every networking device at manufacture. Deciphering recipients at this level
is more straightforward than at Layer 3, where the address of the recipient is
represented by a logical IP address (e.g. 192.168.0.10) and requires greater
knowledge of the surrounding network structure. Due to their more complex
circuitry, Layer 3 switches are more expensive than Layer 2 switches of a
similar build quality and are used more sparingly within installations.
