Patent abstract

A router and method are described herein that provide a “fast leave behavior” by instantly aging out group and source records that are associated with the IGMPv3/MLDv2 protocols. In one embodiment, the router and method are part of a triple play service network including a bandwidth-limited Internet Protocol Television (IPTV) network in which the instantly aging out of group and source records is desirable to implement a fast TV channel changing feature (or fast leave behavior).
