Industrial IoT and TSN
Complex industrial networks have traditionally used special busses or modified version of Ethernet to solve challenges specific to timely delivery and reliability of critical control data. This approach brings two challenges: special-purpose technology makes it more difficult to develop new IoT applications and is costlier to maintain.
To solve these challenges the IEEE created the time sensitive networking (TSN) suite of standards, a successor of IEEE audio video bridging (AVB) that enables minimum latency over Ethernet, seamless redundancy, and centralized configuration and control. With TSN, companies can use standard Ethernet to implement a more cost-effective network that enables a converged IT/OT network that shares the same wire for critical time sensitive traffic and regular traffic.
Solving TSN Test Challenges
Ixia products enable real-world validation of emerging technologies, substantiating the very edge of standards development. Equipment makers and companies use Ixia test equipment to ensure devices and even whole networks meet the conformance criteria of TSN standards and the performance criteria of applications.
Ixia’s IxNetwork™ is a field-proven AVB/TSN test solution, used by industry forums such as the Industrial Internet Consortium TSN Testbed, that validates that components and networks adhere to standards specifications. It is used both by industrial and network equipment manufacturers to validate that their devices adhere to the TSN standards:
- IEEE 802.1Qbv TSN Scheduled Traffic – the foundation for low latency TSN
- IEEE 802.1AS time synchronization of devices and network through gPTP
- IEEE gPTP-rev functionality related to multiple time domains and redundancy
- IEEE AVB standards: 802.1Qav (CBS/FQTSS), 802.1Qat (MSRP), 1722/33
