In this paper, we study multicast tree construction in MPLS network. We discuss the difficulty in combining multi-cast and MPLS in a network. We describe some MPLS proposals for the multicast traffic and we justify the need for defining a new protocol. Thereafter we propose MMT, the MPLS Multicast Tree protocol, which uses MPLS LSP (Label switched Path) between multicast tree branching nodes in order to reduce the multicast routing states in routers and to increase scalability. We present improvements to MMT protocol and we evaluate it in term of scal-ability and efficiency. Finally, we present simulation results to validate our evaluation and we conclude that the MMT protocol seems promising and well adapted to a possible implementation of mul-ticast traffic engineering in the network.
