ABSTRACT:
A method for managing multicast traffic in a data network, and devices using said method. The hosts store for each multicast group an included source record and an excluded source record, and the network interfaces of the hosts send to the router a message containing information about the included source record and information about the excluded source record. The router also stores for each multicast group an included source record and an excluded source record, and updates them when it receives through its network interface a message from the hosts containing information about an included source list and/or information about an excluded source list. The devices are a router, host equipment and network equipment compatible with the method.
