TSN Multiport Switch Core – TSN-SW

TSN Multiport Switch Core - TSN-SW

Currently being developed by the IEEE, Time Sensitive Networking (TSN) is a set of standards aimed at increasing the degree of determinism in switched Ethernet networks according to existing IEEE 802.1 and 802.3 standards. In essence, TSN looks to realize Ethernet networks with guaranteed end-to-end latencies for real-time critical data traffic, transmission of (time-) critical and uncritical data traffic over a converged network, low packet losses and low latency fluctuation (jitter).

The TSN-SW IP Core is suitable for multiport switch devices within TSN Ethernet networks. An internal CPU port and additional four external 10/100/1000+ Mbps are available, which are scalable to up to 16 ports. The IP core consists of up to 16 instances of the TSN-EP IP, a cut-through switching bar as well as additional routing logic specialized on low-latency communication. It is intended for devices in industrial automation, robotics, automotive, aerospace and more.
