The protection relay offers a bandwidth rate limiting functionality to limit the Ethernet/TCP network traffic. The main purpose of this feature is the possibility to divide network segments for different multicast frame types and also to limit the network congestion and traffic towards the protection relay processing during network attacks (such as a Denial of Service attack) or in case of network configuration issues.
The Ethernet rate limiter is configured for 1000 packets per second. The Ethernet filter only allows the subscribed GOOSE packets.
