Patent ID: 8437350

Claim:
Method for controlling access to multicast traffic streams in a packet-switched access network by a client node, said client node being connected to said packet-switched network via an access node, including the steps of: said access node receiving from said client node a multicast request message requesting access to at least one multicast channel; said access node adding identification information to said multicast request message for identifying said client node and forwarding said message to a router capable of routing multicast traffic streams; said access node receiving from said router an acknowledgement message indicative of whether the requested access to said at least one multicast channel is permitted; and streaming said at least one multicast channel to said client node when said acknowledgement message indicates that access is permitted, wherein said step of adding identification information to said multicast request message includes adding information identifying said access node and information identifying a port of said access node to which said client node is connected.
