A communication system for transferring data packets between a network device located within a first network and a network device located within a second network. The data packets having a header allowing each packet to be routed independently through each node of the second network using routing information to process the header of each incoming data packer and forward the data packet to the next node. The headers of each of said data packets entering said first network at an ingress node are encapsulated by assigning at least one label to each data packet so that the data packets can be forwarded by each of the intermediate nodes based on said label without having to process the header information.
