Abstract:
1. A method, comprising: detecting a failure of a primary ad-splicer; conveying a failure information for the failed primary ad-splicer to a redundant ad-splicer; dynamically forwarding one or more pre-spliced packets intended for the failed primary ad-splicer to the redundant ad-splicer; receiving one or more post-spliced packets from the redundant ad-splicer; and transmitting the post-spliced packets towards one or more target receivers, wherein conveying a failure information for the failed primary ad-splicer to a redundant ad-splicer comprises: using a failure detection as a trigger to formulate one or more Internet Control Message Protocol (ICMP) packets; encoding an Internet Protocol (IP) address of the failed primary ad-splicer in the one or more ICMP packets; and transmitting the one or more ICMP packets to the redundant ad-splicer.
