Packet delay characteristic measuring apparatus and method |
摘要 |
A packet delay characteristic measuring apparatus that can accurately only measure a delay in a network even if a delay may occur also in a device that receives packets. The apparatus includes: a sending section for periodically sending out test packets each including sending time information to the network; a branching section for handing over the test packets flowing from the network to each of a plurality of communication paths by electrically branching a communication path; a plurality of receiving sections each of which is connected to the branching section for receiving the identical test packets and calculating delay times based on the sending time information; and a measurement value determining section for comparing a plurality of delay times calculated by each of the plurality of receiving sections for the identical test packets and determining the smallest delay time value as a measurement value. |
