RELY-REC

Time-aware Network Recorder

In critical systems, it is essential being able to analyze the network communications at frame level for 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-REC, a device that is able to inspect, timestamp and record regular Ethernet and high-availability Ethernet traffic, using the same PTP timing reference than the network under analysis.

As an example, due to the critical nature of communications in Electric sector, RELY-REC is an all-in-one solution specifically designed to analyze the traffic in the modern IEC 61850 Digital Substations where the use of combined HSR, PRP and PTP has generated a new challenge for the operators. This device is synchronized with a IEEE 1588-2008 PTPv2 infrastructure, that may be the same shared by the other equipment of the substation.
