Efficient multicast setup mechanism for mobile hosts in MPLS network
This paper proposes an efficient multicast setup mechanism for mobile hosts in multiprotocol label switching (MPLS) network. A management of multicast tree is based on MPLS label. A mobile node (MN) can join a specific multicast group through egress LER after movement detecting. In our mechanism, egress LER has a responsibility to join multicast group and transmit multicast data traffic to MN as remote subscription. After MN joining, data forwarding method uses MPLS-based forwarding. This MPLS-based mobile multicast algorithm can improve performance and solve other mobile multicast problems such as tunnel convergence problem, late join latency, nonoptimized route and complexity
