PACKET SEQUENCE CONTROL METHOD, RECEIVER, TRANSMITTER, AND COMMUNICATING SYSTEM

PROBLEM TO BE SOLVED: To obtain a packet sequence control method which can achieve the effect of broadband and can re-assemble a packet without being influenced by the type or characteristics of a communication line in a communication system which achieves a broadband communication line as a whole using a plurality of communication lines of different types or characteristics. SOLUTION: A packet sequence control method, in a communication system which achieves a broadband communication line using a plurality of communication lines of different types or characteristics, receives a packet at each interface corresponding to each of the plurality of communication lines, wherein each decision unit (12-1, 12-2, 12-3, 13, 14) performs sequence control of a received packet based on a series SEQNO and an SEQNO for each IF contained in the received packet.
