IP-Core für Time Sensitive Networking (TSN)

TSN IP Cores for Ethernet-Networks

Time Sensitive Networking (TSN) is a set of IEEE standards previously developed by the IEEE Ethernet AVB (Audio Video Bridging) task force. These standards enable the transport of time sensitive data streams through standard Ethernet networks without use of  special hardware support and the use of proprietary fieldbus systems. Time-critical data streams can thus be transported with guaranteed latency through a TSN network. The TSN IP Cores developed by the Fraunhofer IPMS eases the integration of TSN into devices used in such networks. 

 

The IP cores can be integrated into FPGAs and ASICs and have currently following substandards implemented

  • Time synchronization (IEEE 802.1 AS)
  • Traffic-Shaping (IEEE 802.1 Qav and Qbv)
  • Frame preemption (IEEE 802.3br & IEEE 802.1Qbu)
  • Low Latency Ethernet MAC communication (IEEE 802.3)
  •  

The TSN IP Cores are available in the following variants

  • TSN-EP - TSN Endpoint Core
  • TSN-SE - TSN Switched Endpoint Core
  • TSN-SW - TSN Multiport Switch Core
