COMMUNICATION DEVICE, RELAY DEVICE AND COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To efficiently perform communication in high speed, with low power consumption and without requiring large resources.SOLUTION: A communication device 2 comprises: a communication unit 9 for communicating with another communication device; an information request unit 5 for issuing an information request to another communication device 3; an information acquisition request generation unit 6 for generating an information acquisition request by adding meta-information to the information request issued by the information request unit 5; and an information request processing unit 7 for generating a pipeline request in which information acquisition requests are coupled as many as possible within a range not exceeding an information separation defined by a protocol lower level than a protocol used when an information acquisition request is transmitted to the other communication device 3 and for transmitting it to the communication unit 9.
