COMMUNICATION METHOD, COMMUNICATION SYSTEM, NODES AND PROGRAM

摘要

To reduce the load caused by a transmission of control information related to data packets and enhance the communication efficiency. When packets are transferred from a transfer node (101) to a transfer node (102), control information stored in each of data packets (301) is shifted therefrom to a leader packet (302) located in the front portion of a packet block (300-1) and then transmitted from the transfer node (101) to the transfer node (102). When receiving the packet block (300-1), the transfer node (102) controls, based on the control information in the received leader packet, the transmission of the packets to be transferred to the transfer node (101).
