<p>PROBLEM TO BE SOLVED: To reduce the overhead of a network in a communication data transfer method, based on MPLS procedures. SOLUTION: When label switching paths are used to transfer communication data a transmission source node acquires a label corresponding to a specific destination node and acquires information of a node in the last stage of a label switching path corresponding to this label. If this node in the last stage is matched with the destination node of data to which the transmission source node is to communicate, the transmission source node adds the acquired label and a simple header, which doesn't include information of the transmission source node other than of the destination node, to a data main body to generate a packet and transmits this packet. Thus duplicate storage of information of both the transmission source node and the destination node in the packet is prevented to reduce the overhead of the network.</p> |
