What is Time-Sensitive Networking (TSN)?
TSN represents a collection of IEEE standards that allow Ethernet to be used as a common network interface for all devices. This works by defining a variety of standards with two main goals:
Deterministic Latency and Guaranteed Delivery
To solve these challenges, the IEEE created the 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 network that enables a converged IT network that shares the same wire for critical time sensitive traffic and regular traffic.
Solving TSN Test Challenges
Keysight products enable real-world validation of emerging technologies, substantiating the very edge of standards development. Equipment makers and companies use Keysight test equipment to ensure devices and even whole networks meet the conformance criteria of TSN standards and the performance criteria of applications.
Powered by Novus ONE PLUS, NOVUS-S 100GE / 50GE / 25GE / 10GE, Novus mini, and IxNetwork, a field-proven AVB / TSN test solution validating that components and networks adhere to standards specifications. It is used by aerospace, automotive, industrial, Pro AV, and network equipment manufacturers and industry forums such as the Industrial Internet Consortium TSN Testbed to validate devices adhere to the TSN standards mentioned below.
