Nowadays, convergence to Ethernet networks is becoming a reality at all levels. Additionally, in critical sectors like automotive, aerospace, railway, industrial automation, etc., this Ethernet convergence must go hand-in-hand with determinism for avoiding critical traffic to be affected by non-critical traffic. Time-Sensitive Networking has come out as the definite solution for covering these demands.
However, due to the complexity of TSN networks, it is essential being able to analyse the network communications at frame level for protocol validation, performance analysis, conformance testing and forensic purposes. Furthermore, the validity of this analysis will be constrained by the capability of the infrastructure to correlate the frames with a common time reference.
For that purpose, Relyum has developed RELY-TSN-REC, a device that is able to inspect, timestamp and record regular Ethernet and Time-Sensitive Networking traffic, using the same IEEE 802.1AS timing reference than the other equipment in the network under analysis.
