发明名称 Communication device
摘要 Provided is a communication device for measuring a usable bandwidth without delay in transmission of primary data. The relay device according to an embodiment of the present invention, when measuring a usable bandwidth in communication with another relay device, processes a user packet including a user data to be transmitted to the other relay device so as to be changed into a specific packet size while the user data is maintained as it is, and utilizes it as a measurement packet. Accordingly, even though it is a measurement packet for performing measurement of a bandwidth, since it includes user data, it may be treated in the same manner as a user packet thereby enabling an efficient use of a communication network in communication. Also, even though UDP is used, since a usable bandwidth can be measured, it is possible to measure a bandwidth even though streaming data is distributed while preventing any influences on the distribution.

主权项 1. A communication device, comprising: a setting unit that is configured to set a test bandwidth indicative of a transmission rate to be tested in a communication with another device; an acquisition unit that is configured to acquire a user packet in which user data indicative of contents to be transmitted to the other device is packetized; a processing unit that is configured to assign measurement information indicative of the test bandwidth which is set by the setting unit to the user packet acquired by the acquisition unit, and to process the user packet to prepare a measurement packet so that a packet size of the measurement packet becomes a packet size corresponding to the test bandwidth; and a transmission unit that is configured to transmit the measurement packet prepared by the processing unit to the other device at intervals determined so as to come into an environment in the test bandwidth which is set by the setting unit.
