Method for transporting data packets, data network system, and network nodes

摘要

A method for transporting data packets, a data network system and network nodes are provided. According to the present invention, subframes are classified according to their forwarding paths when entering a network from an ingress node; subframes with the same forwarding path are encapsulated into a multiframe; the multiframe is transported via intermediate nodes; and the multiframe is de-encapsulated into the original subframes at an egress node. According to the present invention, traffic to enter the network is processed at an edge node of a network, so that small data packets (subframes) are encapsulated into a large data packet (multiframe) for increasing a minimum data packet length, and the subframes are recovered from the multiframe when the traffic exits the network for reducing the burden of traffic processing in a transport network.
