IPC: H04L45/50
Filed: 2001-08-18
Abstract: PURPOSE: A multicast method in an MPLS(Multi-Protocol Label Switching) network is provided to generate multicast connection between an LSR(Label Switching Router) and an LER(Label Edge Router), so as to enable high-speed switching in a layer-2 without using an LSP(Label Switching Path) for unicast in multicast data packet transmission.

An ingress LER confirms a protocol type of an IP header of an IP packet received from a non-MPLS network(S2), to check whether the protocol type is an IGMP(Internet Group Message Protocol) message(S3). If so, the IGMP message is forwarded to a non-MPLS port registered for multicast and MPLS control boards of each system(S4). And if a protocol type of the IP header is not an IGMP message but a multicast data packet, the multicast data packet is transmitted through multicast connection(S5).
