SYSTEM AND METHOD FOR LAYER 3 RING PROTECTION WITH ADAPTIVE BANDWIDTH MICROWAVE LINKS IN A NETWORK ENVIRONMENT

摘要

A method is provided in one example and includes receiving a current bandwidth characteristic for a link, where the current bandwidth characteristic is determined under fading conditions associated with signal propagation on the link. The method can also include calculating a new cost for the link that is different from a nominal cost associated with a nominal bandwidth of the link without the fading conditions. The method could also include routing at least a portion of a plurality of flows that are to traverse the link away from the link based, at least in part, on the new cost. Another example method includes receiving the current bandwidth characteristic for the link, comparing the current bandwidth characteristic with a preconfigured low watermark corresponding to a class-specific MTR topology associated with a class of traffic traversing the link, and removing the link from the MTR topology based on the current bandwidth characteristic.
