DEVICE AND METHOD FOR MANAGING SUBSCRIPTIONS TO MULTICAST TRANSMISSIONS

摘要

The invention relates to managing requests for subscription to multicast transmissions in a communication network, at least two branches thereof being interconnected by an interconnection device comprising a module consuming such subscription requests preventing the propagation of said requests from one branch to another. At least one of said branches comprising at least one bridge device, the interconnection device comprising a subscription announcement module, said subscription announcement module performs the following step: upon reception (404; 412) via a branch of a first request for subscription to a multicast transmission, transmitting (407; 415) a second request for subscription to said multicast transmission at least via the branch via which said first subscription request was received.
