CARRIER CLASS RESILIENCE SOLUTION FOR SWITCHED ETHERNET LOCAL AREA NETWORKS (LANS)

摘要

A Carrier Class Ethernet switch is described herein that has a resilient Switch control system (RSCS) which manages redundant switch matrixes that use redundant links to connect to one or more application blades (e.g., switches, end stations) . The Ethernet switch has Carrier Class characteristics because a Rapid Link Supervision Protocol (RLSP) is used to detect a fault in anyone of the redundant links between the redundant switch matrixes and the application blades. And, a RLSP distribution policy is used to coordinate and control isolation measures between the redundant switch matrixes and the application blades. Also described herein is a method for providing resilient Ethernet connectivity in a network.
