System for passive alarm propagation and suppression for packet based networks

摘要

A system for passive alarm propagation and suppression in a communication network is disclosed. The system includes a packet based network including one subset of network providing connectivity to other set(s) of network. The network includes a first edge node and a second edge node; a first customer node connecting to the first edge node and a second customer node connecting to the second edge node; and a replicated alarm suppression table (RAST) residing in the first provider edge node.
