Method and system of protection switching in a network element

摘要

A method and system protects switching in a network element. At least one data signal at the client entity is received, wherein the signal flow through server entity via the client entity. A configuring protection group on at least one client entity is served by at least two server entity, wherein the protection group includes at least one work entity and at least one protect entity. A plurality of supplement client entities of client entity is created such that at least one of the supplement client entity flows over one server entity and checking the entities for a fault to raise alarm to their respective controllers. The controller includes at least one server layer protection controller and at least one client layer protection controller.

1. A method of protection switching in a network element, the network element comprising a centralized switch fabric including at least one client entity over at least one server entity, the method comprising:
receiving at least one data signal at the client entity, wherein the signal flow through server entity via the client entity; configuring a protection group on at least one client entity served by at least two server entities, wherein the protection group includes at least one work entity and at least one protect entity; creating a plurality of supplement client entities of client entity such that at least one of the supplement client entity flows through one server entity; and checking the entities for a fault to raise alarm to their respective controllers, wherein each respective controller includes at least one server layer protection controller and at least one client layer protection controller, wherein a decision of the client layer protection controller to switch traffic to one of the client entities, undergoes a physical translation process which in turn switches the traffic to this translated client entity on the central fabric.
