METHOD ENABLING FAST SWITCHING BETWEEN MULTICAST TREES |
摘要 |
<p>Presented are a system and method of detecting a multicast tree link failure and performing a fast switch from the failed multicast tree communication path to a secondary multicast tree communication path. The methods are suitable for leaf nodes in a multiprotocol label switching network. The method generates a count of communication path failure detection packets and a count of communication path failure detection packets plus other packets and compares the counts to determine the status of the link. The system includes two counter components and a comparison component.</p> |
