Abstract
Method and system for providing ad-splicer N+1 redundancy in a network by employing IP network intelligence and techniques to facilitate a redundant ad-splicer assuming, within a few seconds, the functionality of the failed primary ad-splicer. The network triggers the installation of unicast and multicast routes on an interface by tracking one or more unicast routes to deliver the unicast and (pre-spliced) multicast traffic to the redundant ad-splicer. The network dynamically adjusts the multicast trees to continue to deliver the post-spliced multicast traffic to the intended receivers.
