    摘要: A method for multicasting data packets is provided. The method includes preparing multiple point to point connections between a root node and multiple destination nodes to establish point to multipoint connections. The method also includes receiving, at an intermediate node which is operatively connected to the root node and a plurality of the destination nodes, a data packet from the root node. In addition, the method includes determining whether the received data packet is a multicast data packet and generating a plurality of the data packets by copying the received data packet if the received data packet is a multicast data packet. Furthermore, the method includes forwarding the copied data packets to a plurality of the destination nodes.

    摘要: According to one embodiment of the invention, a method for multicasting data packets is provided. The method includes determining that a data packet is to be multicast from an intermediate node to a plurality of destination nodes in a branch of a point-to-multipoint MPLS connection tree. The intermediate node has a plurality of connection interfaces. The method also includes establishing only one MPLS tunnel in response to the determination. The only one MPLS tunnel is for carrying the data packet to be multicast and established between a node and the intermediate node. The method also includes connecting each destination node to the intermediate node through a particular one of the connection interfaces. The method also includes receiving the data packet from the node at the intermediate node through the only one MPLS tunnel. The method also includes forwarding the data packet to the plurality of destination nodes through the connection interfaces identified in a multicast table.

    摘要: A method and system for routing an externally generated message in a network includes receiving at an ingress port of a network a message from an external network. The message includes Internet protocol (IP) source and destination addresses and message data. The IP source and destination addresses are translated to internal addresses that are non-forwardable in the external network. The message data is routed in the network based on the internal addresses.
