METHOD AND SYSTEM FOR PROTECTING A SUB-DOMAIN WITHIN A BROADCAST DOMAIN |
摘要 |
<p>A method and system for protecting a service available on a broadcast domain. A sub-domain is established within the broadcast domain. The sub-domain includes a group of nodes used to provide a communication path to the service. A primary sub-domain maintenance association and a back-up sub-domain maintenance association are monitored. The primary and sub-domain maintenance associations are a set of primary and back-up paths, respectively, representing connectivity between nodes acting as edge nodes in the sub-domain. A fault is detected within the primary sub-domain maintenance association and a switch to the back-up sub-domain maintenance association occurs.</p> |
