Fixed priority queue service apparatus and its service method using connection-specific frames defined by counter interworking in ATM network

摘要

The present invention relates to an ATM network in which jitter is adjusted in each node using a connection-specific frame in an ATM network, a high priority is assigned to each connection frame in order of a small size, The present invention relates to a fixed priority queue service apparatus using a connection-specific frame defined by a counter interworking in a network and a service method thereof,_{i, j}) Is installed and this counter (C_{i, j}) For each connection, wherein each frame is defined as a connection unit, and the counter is defined by counter interworking in an ATM network, wherein the virtual channel (VC0 Jitter adjusting means (9 to n) for adjusting the jitter of the cell data of the frame from the frame memory (1 to VCn); And a fixed priority scheduler 20 for assigning high priority to frames of each connection from the jitter adjusting means 9 to n in order of small size and then servicing the cells in priority order.
