Communications relay device, a communication relay system, a communication relay method, and a communication relay program

摘要

Even if [Problems] destination in the congestion state, making it possible to perform data relay process without using a buffer [SOLUTION] The communication relay device specifies the destination of the input packet, the input packet is a determined packet input processing unit whether a packet of the communication delay time is limited includes a congestion monitoring means for monitoring the congestion status of the destination, after delaying a certain period of time the output timing of the input packet, and the delay means to re-enter the packet to the packet input processing means, the. Packet input processing means, the input packet and the destination is a packet of the communication delay time is not restricted when it is in the congestion state, to bypass transfers input packets to the delay means
