Patent ID: 7987259

Claim:
A method of providing ad splicer redundancy in a network, comprising the steps of: monitoring an availability of a first ad splicer that receives a unicast ad traffic addressed to the first ad splicer and a pre-spliced multicast traffic, and produces a post-spliced multicast traffic; detecting a failure of the first ad splicer; dynamically forwarding, in response to the detected failure of the first ad splicer, the unicast ad traffic and the pre-spliced multicast traffic to a second ad splicer; utilizing the forwarded unicast ad traffic addressed to the first ad splicer and the pre-spliced multicast traffic by the second ad splicer to generate the post-spliced multicast traffic; receiving at a router the post-spliced multicast traffic from the second ad splicer; and transmitting the post-spliced multicast traffic generated by the second ad splicer is to one or more target receivers.
