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.
