Abstract:
1. A method of fault status suppression in a communication network, wherein the communication network includes a plurality of network elements, wherein the communication network is organized into a plurality of logical groups, wherein each of the plurality of logical groups includes one or more of the plurality of network elements, wherein one or more of the plurality of network elements in one of the plurality of logical groups is virtually partitioned from at least one network element in another of the plurality of logical groups, wherein at least one of the plurality of logical groups includes a detector for receiving fault data, the method comprising: receiving fault data from the detector identifying a fault status of a first network element; determining a first logical group from among the plurality of logical groups for said detector and a second logical group from among the plurality of logical groups for said first network element; and suppressing a fault on said first network element when the first logical group of said detector and the second logical group of said first network element are different and there is a fault on a second network element providing a communication path between said first and second logical groups.
