RFC 2544 Compliance Testing

Performs the RFC 2544 automated test suite at all recommended frame sizes as well as user configurable frame sizes and up to full line rate. The test suite can be performed with the far end test partner in loopback mode or peer-to- peer mode – the latter allowing for symmetrical/asymmetrical testing. Thresholds may be configured for accurate SLA assurance and verification. The automated tests supported are throughput, Latency, Frame Loss, and back-to- back frames.

In Advanced SLA Mode this feature combines the powerful multiservice throughput test capabilities with the RFC 2544 industry test suite for SLA verification. Using this test function, service providers are able to verify SLAs while end-to-end QoS is assessed properly. By configuring one primary test stream and up to seven background streams each with independent frame size, bandwidth, and more importantly QoS levels, simulating different service applications is now realized. The Advanced RFC 2544 SLA mode provides detailed visibility of the test parameters for each of the traffic streams being measured, providing an efficient in-depth qualification in a fast and automated way.

Automated tests compliant with RFC 2544 with configurable threshold values and maximum transmit bandwidth settings. Throughput, Latency, Frame Loss, and Back-to-Back (burst) tests. Frame sizes: 64, 128, 256, 512, 1024, 1280, 1518 bytes and 2 user configurable frames. Tests can be done to a remote loopback or in Peer to Peer mode to a remote test set configured as a responder.

Smart Loopback Mode

Four modes are available for looping back test traffic. At Layer 2, all incoming unicast traffic is looped back with the MAC source and destination addresses swapped. At Layer 3, all incoming unicast traffic is looped back with the MAC and IP source and destination addresses swapped, and at Layer 4, all incoming unicast traffic is looped back with the MAC, IP, and UDP/TCP ports swapped.

Configurable traffic filters are supported on all MAC, IP, and VLAN
fields to allow full control over looped traffic. Traffic is monitored while being looped and key traffic metrics such as frame type, rate, and error/alarms are displayed on screen. These can be compared to results at the far end to pinpoint issues more easily.

Layer 2: Incoming traffic looped back with MAC source and destination addresses swapped.
Layer 3: Incoming traffic looped back with MAC and IP source and destination addresses swapped.
Layer 4: Incoming traffic looped with MAC, IP, and UDP/TCP ports swapped.

All key measurements on received traffic provided on loopback unit.

Intelligent Device Discovery & Remote Control 

Easily discover and select another VEEX Ethernet tester or loopback device on the network under test. The local device will control the operation of the far end device, in either loopback or peer-to-peer mode (symmetrical or asymmetrical traffic generation mode). This feature greatly simplifies field testing since there is no need for a second technician to be at the far end configuring the test partner device.

Discovery function to all VEEX devices within subnet or manual control of VEEX test sets in routed network.
Remote Control of Loopback capability.
Peer to Peer Controller/Responder configuration for RFC 2544 test with asymmetric bandwidth test capability for end-to end RFC 2544 test.

Scans incoming traffic and discovers all VLAN flows including Q-in-Q tagging.
Key statistics on traffic rates, alarms and errors are reported for monitored streams (up to 10).

Layer 2 Control Protocol Transparency Test

To verify handling of Layer 2 Control Protocol (L2CP) frames accross Carrier Ethernet networks, the Layer 2 Control Protocol Transparency Test feature transmits a set of L2CP frames and verifies that they are forwarded through the network. This feature supports common L2CP frame types (as per MEF 45 standard) as well as Cisco L2CP frame formats.

• Selectable Layer 2 Control protocol frames and configurable frames.
• Supported L2CP frame types per MEF 45 standard.
• Cisco L2CP frame formats.
• Selectable frame rate and count.
• TX and RX frames statistics.

Q-in-Q (VLAN stacking)

VLAN stacking, also known as Q-in-Q, makes a provision for carrier/service provider assigned VLANs (SP-VLAN), but also retains customer traffic’s VLAN (CE-VLAN). Up to three layers of VLAN tagging supported with configurable VLAN ID, Priority, and VLAN type.

Multiprotocol Label Switching (MPLS)

MPLS technology allows for a more efficient routing of Ethernet/ IP packets via the use of MPLS routers in the network. MPLS labels reside between the MAC (Layer 2) and IP layers (Layer 3). Up to three MPLS tags can be configured in the traffic stream with customizable Label, CoS, and TTL fields.

Provider Backbone Bridging (PBB)

Also known as MAC-in-MAC, PBB (802.1ah) provides a trunking mechanism that adds resiliency and configurable performance levels in the provider backbone network. PBB encapsulation is available for all Ethernet tests with all PBB fields configurable.

Point-to-Point Protocol over Ethernet (PPPoE)

PPPoE provides encapsulation of Ethernet frames with a PPP header commonly used for DSL Access or GPON.

Multiprotocol Label Switching Transport Profile (MPLS-TP)

MPLS-TP, a Layer 2 packet-based transport mechanism, is gaining momentum as a transport of choice for access and aggregation networks requiring a technology that combines the operational simplicity of packet switched networks with the operations, administration and maintenance (OAM) tools and fault resiliency capabilities of circuit switched networks. Fully configurable MPLS-TP header fields including LSP and Pseudo wire.

Layer 4-7 Features

RFC 6349 V-PERF TCP Test

A common source of customer complaints come from file transfer speeds not matching the throughput rates guaranteed in the SLA. While many factors affect TCP applications performance, including customer’s operating system hardware performance and settings (TCP window size), carriers need to prove SLA with a test tool that can show TCP performance independent of Operating System or Server limitations and present repeatable reliable results.

The test set V-PERF feature uses RFC 6349 test methodology and metrics for qualifying network TCP performance. It offers a full line rate stateful TCP test with configurable window sizes, client and server modes as well as compatibility with iPerf servers.

TCP Throughput Compliant with RFC 6349 Stateful TCP Test at line rate TCP Client and Server modes Compatible with iPerf Client/Server MTU search per RFC4821 Round Trip Time Measurement Configurable TCP Window sizes Multi-Window size tests
Measurements: TCP Throughput rate (min, max, average), Transfer file size and duration, Transfer time ratio, TCP Efficiency %, Buffer Delay %

Quality of Service (QoS) & Quality of Experience (QoE) Verification Tests

FTP Throughput (V-FTP) and V-TEST features provide additional Layer 4-7 testing. The V-FTP Throughput feature allows the user to test up to full line rate FTP protocol performance to any FTP Server by uploading and downloading files. The V-TEST feature qualifies network TCP/HTTP protocol performance by testing against a V-TEST HTTP server. Both features can test up to the full line rate depending on the server specifications and limitations. Connection time to the server, data transfer time, line rate throughput rates, and protocol (FTP and HTTP) throughput rates key metrics are reported during the tests.

The V-TEST application is flexible enough to operate in different modes depending on user preference; VeEX Managed mode, Speedtest Powered™ mode based on Ookla® technology, and User Managed mode.

In VeEX Managed mode, the customer’s servers are added to a customer server list that is maintained and managed by VeEX for the end-user’s ease of use and convenience. The full list of server IP addresses or URLs are provided to VeEX. Once added, all the user has to do is select the server from their company list and initiate the test to the selected server.

In Speedtest Powered mode, the test follows Ookla’ s methodology and tests to the Speedtest® Server Network. In this mode, the test is compatible with Ookla’ s protocol/ methodology; it will scan nearby servers in the local market and test to the server with the fastest (lowest Latency) response.

In User Managed mode, the user is allowed to enter the server IP/URL and save it to a server list that they can maintain and manage on their own.

Auto Scripting

The Auto Scripting feature is the perfect tool for the lab environment where multiple short-term or long-term test configurations are required to stress the network equipment and/or network under test, in order to measure and qualify the performance capabilities. The feature is also important in field operations, not only to speed-up service turn-up times, but also to facilitate the entire workforce the same test profiles and test procedures for day-to-day operations.

The Auto Scripting application is an automated sequence of tests that can be carried out by selecting previously configured Throughput or BERT profiles. The profiles can be created with ReVeal and then loaded to the unit or created directly on the unit in the Throughput and BERT applications. Users can select up to ten profiles, each profile configured with its own duration. The duration can be in seconds, minutes, hours, or days. The test sequence will begin with the first profile configured with its corresponding duration, followed by each profile after that. At the end of each profile tested a results file will be stored automatically before the test sequence continues to the next profile. Users have the option to continue or stop the auto scripting test if errors or alarms are detected.

Quick and Intuitive Graphical Setup

The combination of SDH/SONET and PDH/DSn, common in today’s network environment, can create complex test scenarios.
Therefore technicians need a tool that is quick and easy to configure. Intuitive graphics, drop down menus and touchscreen operation greatly simplify test interface, signal structure, payload mapping and test pattern setup.

Test configuration, menus, and results are presented in VeEX’s intuitive hierarchical test signal builder GUI, requiring little or no training for new or existing VePAL™ users, maintaining a consistent user experience from the lab to the field. Framed signals can be equipped with unstructured or structured payloads with selected test pattern filling the entire test payload (Bulk) or a structured payload (SDH/SONET framed client signal) with or without PDH/DSn multiplexed clients.

Layer-based graphical configuration interface allow users to build the test signal in a logical layer by layer sequence

• SDH/SONET/PDH/DSn interface selection.
• Optical or Electrical signal settings.
• Mapping and Multiplexing.
• Payload (Bulk and multiplexed).
• Test Pattern

Physical Layer Testing

Verifying that signals are within prescribed specifications and limits is recommended prior to performing framing and payload analysis. High optical power levels can saturate receiver equipment, while low power levels are susceptible to noise which result in bit errors. Clock tolerances for each individual signal hierarchy is clearly defined by Telcordia and ITU-T recommendations and should be verified as part of any acceptance/conformance test.

Payload Mapping and Multiplexing

Test the operation of Add/Drop Multiplexers, Digital Cross Connects and other Network Elements (NE) by verifying the correct mapping and de-mapping of different tributaries and payloads into SDH and SONET containers, monitoring any anomalies and defects at every multiplex level, according to ITU-T and Telcordia recommendations.

PDH/DSn client can be multiplexed and mapped into SDH/ SONET.

Complete Overhead Decoding and Generation

Binary, hexadecimal and detailed text decode of all applicable Section, Path overheads and Framing word bytes are performed through individual byte and bit selection or through dedicated test applications (e.g. APS, Payload Labels, Pointer Tasks)

Overhead byte control allows the manipulation and easy encoding of transmitted overhead bytes in both terminated and payload through modes to stress the network responses to various conditions.

Service Disruption Time and APS

SDT and Automatic Protection Switch timing measurements use trigger events to measure outages and link recovery timesat different levels and evaluate them against Pass/Fail criteria. It also provides detailed events recording to understand what happened during the service outage.

Error Insertion and Alarm Generation

Alarms and Errors can be inserted into any of the mapping or multiplexing layers, from line signal to the test payload itself. A full range of SDH/SONET and PDH/DSn defects and anomalies are supported depending on the signal structure setup. Single errors, preset rates or user-defined error rates are supported.

Intuitive Test Results

A summary screen quickly reports signal status and critical Error and Alarm parameters with easy-to-read Pass/Fail indicators. Additional screens accessed via a simple tab system display signal levels, anomalies and events.

Alarms and Errors overview with history indicators provide direct (touch) access to counters and statistics and complement the soft LEDs with a layered representation of all defects and anomalies.

SDH/SONET Testing

Installation, bring-into-service, and maintenance of SDH/SONET and PDH/DSn networks is simplified thanks to a combination of intuitive features and powerful test functions. SDH/SONET signals are often compromised by various impairments in the multiplexing process therefore defining the type of anomaly or defect to isolate the network element or signal path causing the problem is crucial. Fast troubleshooting and comprehensive analysis of transmission problems can be performed using intrusive, non-intrusive and monitoring test modes. Novice users will benefit from the easy-to-use Auto-configuration and Tributary Scan test modes, while experienced users will appreciate the array of advanced features such as Overhead Monitoring and Byte Control, Pointer Test Sequences, Path Trace Generation, Tandem Connection Monitoring and lots more.

For FC-1, frequency fluctuations, transceiver noise and phase jumps are tested using CRPAT, CSPAT, and CJPAT patterns. Data dependency and behavior of network components are checked with PRBS patterns, sequence number tracking, and time stamping to calculate Frame Loss, round trip delay, and other performance metrics.

RFC 2544 Benchmarking

Based on the Ethernet test methodology, the RFC 2544 routine has been adapted to Fiber Channel circuits where flow-control and buffer verification is important. The feature checks throughput and round trip delay at various buffer sizes to verify optimal buffer size and best possible link performance.

FEATURES

Fiber Optic Tools

Digital Fiber Inspection Scope

Dirty connectors can damage or degrade the performance of expensive optical modules, or produce inaccurate results. Inspecting and cleaning patch cords and pluggable optics connectors before mating them is always recommended.

This option allows digital video microscope probes* to be connected directly to the TX300s through a USB 2.0 port. Featuring live video feed on the TX300s screen for visual analysis. It offers image capture, compare (before and after), IEC 61300- 3-3 Sect 5.4 Pass/Fail templates for SMF and MMF, save, export and generate report to USB flash drives.

Visual Inspection

• Visual file selector.
• Image comparison for before-after reports

Auto-Focus Detection and Analysis option

Test set automatically detects when image is in-focus, captures the image and analyzes it. This process is faster than complex mechanically-driven auto- focus systems as it uses human fast reaction and finesse.

• Analysis per IEC 61300-3-3.
• SMF and MMF templates (Core, Cladding, Adhesive and Contact areas).
• Dots or square to highlight contamination, debris and scratches.
• Report Generation.

*USB Fiber Scope sold separately. Check its datasheet for details.

OTDR Viewer

Built-in OTDR Viewer and Client application provides full postanalysis of SOR traces, as well as control of OPX-BOX OTDR via direct USB connection or Bluetooth®.
