SYSTEM FOR PROVIDING FABRIC ACTIVITY SWITCH CONTROL IN A COMMUNICATIONS SYSTEM

摘要

Disclosed is a system for providing redundancy on a communications switchplatform having adata plane for processing data. The data plane includes an active fabrichaving an ingress and anegress and establishing a first datapath, a redundant fabric having an ingressand an egress andestablishing a second datapath, and a fabric switch for aligning the egress ofone of said fabricsto a system output. A separate and independent control plane is provided formonitoring theprocessing of data. The control plane includes: (i) a plurality of monitorsoperatively connectedto monitor the status of the active and redundant fabrics in the data planefor a fau and(ii) a fabric activity switch circuit adapted to determine whether the faultoccurred in the activefabric in the data plane, and if so, to generate a fabric activity switchsignal directed to said fabricswitch in the data plane.
