Abstract
A failure detection mechanism provides enhancements to PIM SM based fast re route techniques. A network node upon detecting a loss of connection determines whether it can re route multicast data traffic. If the network node does not have a failure free secondary path it can originate a notification packet and send it to the downstream parts of a multicast tree. The notification packet can trigger one or more downstream nodes to switch over to redundant secondary paths to re route the multicast data traffic.
