Abstract
A method of delivering an IP multicast stream from a source node to a destination node. The method comprises establishing a Host Identity Protocol association between a multicast router and at least one further network node upstream of the multicast router, both of which are present in the multicast path, and using said association(s) to transport multicast packets.
Claims28
A method of delivering an IP multicast stream from a source node to a destination node, the method comprising establishing a Host Identity Protocol association between a multicast router and at least one further network node upstream of the multicast router, both of which are present in the multicast path, and using said association(s) to transport multicast packets.
An IP multicast router comprising a Host Identity Protocol client and being arranged to establish a Host Identity Protocol association with an upstream multicast router between itself and an IP multicast source node, or with an IP multicast source node, for the purpose of transporting an IP multicast stream from the source node to a downstream destination node.
A user terminal comprising a Host Identity Protocol client, the terminal being arranged to send a service discovery message to a multicast router and which contains a first multicast group identity, to establish a Host Identity Protocol association with said multicast router, to receive a second multicast group identity from said multicast router, to send a join instruction to said multicast router containing said second multicast group identity, and to subsequently receive an IP multicast stream over said Host Identity Protocol association.
