COMMUNICATION METHOD, COMMUNICATION DEVICE, AND COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress the degradation of throughput in a communication system that has plurality of communication devices to reply a reception result of multiple address communication. SOLUTION: Each communication device (client terminal 20) replying a reply packet is provided with a delay processing section 24, the delay processing section 24 generates a random number when a received packet denotes multiple address communication and decides a delay time based on this random number and delays the reply packet sent from a communication control section by the delay time. Thus, it is avoided that the reply packets are concentrated onto a sender (server terminal 10) at the same time.
