<p>The invention provides a packet transmission method and apparatus which prevent the holding of unavailable links during packet transmission. An embodiment of the present invention assumes that the case of a packet transmission between transmitting terminal x and receiving terminal y which includes seven of links 0 to 6 and switches 1 to 6. Switches 3 and 5 are connected with burst servers 1 and 2, respectively, which have a buffer for temporarily holding of a message packet and a function of the packet transmission. The function comprises to request a link reservation, to transmit message packet, to store the received message packet, to release the reserved links upon completing the transmission of message packet. When transmitting terminal x transmits a message packet, burst server 0 starts the packet transmission including the link reservation to burst server 1, and when the packet transmission is completed, reserved links 0, 1, 2 are released. The same packet transmission is repeated consecutively to each burst server until receiving terminal y if the link reservations are not blocked. If a link reservation is blocked at a link, the packet transmission is held the last burst server, and another link reservation is using the same bandwidth or converting the bandwidth to another available bandwidth. <IMAGE></p> |
