<p><P>PROBLEM TO BE SOLVED: To prevent the overflow of a reception buffer memory, to reduce the number of times of retransmission for packet discard in TCP communication, and to improve the speed performance of the TCP communication, with respect to a packet data relay apparatus. <P>SOLUTION: Packet data inputted from a reception port to which a server terminal or the like is connected are stored in the reception buffer memories 1-1, 1-2 and 1-3, and then the packet data are sent out from the reception buffer memories 1-1, 1-2 and 1-3 to a transmission port to which a client terminal or the like is connected. The reception rate of each reception port is monitored in a reception rate monitoring part 1-4, and the memory region of the reception buffer memory (reception buffer memory 1-2, for instance) of the reception port wherein the degree of congestion is low and the reception buffer memory (reception buffer memory 1-3, for instance) of an unused port is allocated to the reception buffer memory (reception buffer memory 1-1, for instance) of the reception port wherein the degree of the congestion is high. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
