Datasheet

Overview

VIAVI Time-Sensitive Networking (TSN) test solutions cover conformance, functional and performance testing of TSN/AVB-enabled networks, cabling, devices and systems. They are used for in-car and Car2X automotive Ethernet as well as industrial and telecom applications, where TSN protocols defined by IEEE provide deterministic transport for time-critical traffic.

Conformance testing

Conformance testing is performed with TTworkbench and the TTsuite test suites, which provide predefined, fully automated test scenarios for individual TSN standards: Time Aware Shaper (IEEE 802.1Qbv), Filtering and Policing (IEEE 802.1Qci), Frame Preemption (IEEE 802.1Qbu / IEEE 802.3br), Redundancy (IEEE 802.1CB) and gPTP time synchronization, plus AVB suites based on Avnu Alliance automotive test plans. Tests can be run against bridges and end stations (an Upper Tester is required for end station tests), and PCAP files with the complete traffic are appended to the log of each test case execution.

Performance and functional testing

Performance and functional testing uses the VIAVI TestCenter application with TSN packages. The solution emulates TSN/AVB and non-TSN/AVB capable end-points, allowing a realistic automotive Ethernet environment with multiple connections, domains and traffic profiles, mixed TSN and non-TSN traffic generation on each port, TSN-specific metrics and timing measurements, real-time capture and full protocol decode in Wireshark.

Hardware platforms

The TSN & Automotive C2 Appliance is a compact, portable 2U Layer 2-3 test platform with up to two interface cards and up to 8 Ethernet ports, including 10Base-T1S and 100/1000Base-T1 interfaces. The TSN and Automotive M1 Appliance is a 2U Layer 2-3 test platform with 4 to 20 ports at speeds from 10M to 10G, with traffic and protocol performance identical to fX2 mainframe test modules. Both offer 2.5 ns Tx timestamp resolution with intra-chassis and inter-chassis synchronization.

Key Features

  • Full TSN/AVB emulation of multiple talkers or listeners on each port
  • Mixed TSN and non-TSN traffic generation capability on each port
  • Standard-specific wizards and result views for configuration and analysis
  • TSN-specific metrics and statistics measurements

  • Real-time capture and analysis with full protocol decode in Wireshark
  • Predefined, fully automated conformance test scenarios covering the IEEE standards
  • Bridge and end station tests (Upper Tester required for end station tests)
  • PCAP files with complete traffic appended to the log of each test case execution
  • Extensible for different profiles (IEEE, Avnu Alliance or IIC)
  • Visual failure analysis and test report creation with customization options
  • Tests for both store-and-forward and cut-through switches
  • Flexible timing protocol support: IEEE 1588, 802.1AS or AS-Rev
  • 2.5 ns Tx timestamp resolution with intra-chassis and inter-chassis synchronization
  • External timing sync via direct connect, NTP, PTP, GPS and CDMA
  • MACsec supported on C2 and M1 appliances
