Abstract: Provided are a connection management mechanism and a connection management method with which computer bus connections can be managed such that failures and freezes do not occur in a computer system when delays and packet losses occur. A connection management unit, which is used in computer bus communication in which packets are transmitted between a request source and a request destination, has a dummy return packet generation/transmission function wherein a dummy return packet is generated and is transmitted to the request source when a delay or loss occurs in a return packet transmitted from the request destination, and/or a filter function wherein, after transmission of the dummy return packet, a legitimate return packet arriving from the request destination is discarded.

Abstract: [Problem] In a case where a plurality of packets are compiled for transmission to a network, the length of data to be continuously transmitted to each of a plurality of destinations is increased and hence the time interval in which the packet(s) addressed to each destination gets a transmission opportunity is increased, with the result that the packet delay is disadvantageously increased. [Solution] A packet extraction unit (22 of FIG. 2) extracts a plurality of packets as a whole from a packet compilation queue (21 of FIG. 2) that sorts, according to destinations, and stores packets. A limited number of packets to be extracted as a whole at this time is given in accordance with a maximum packet compilation number defined by a maximum compilation number calculation unit (29 of FIG. 2) on the basis of a band increase and a delay increase due to a packet compilation.
