Abstract
A protocol for detecting faults in a bidirectional path between two forwarding engines, where parts of the bidirectional path checked may include interfaces, one or more data links, and to the extent possible the forwarding engines themselves, with potentially very low latency. The protocol may operate independently of media, data protocols, and routing protocols.
