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

摘要

According to the present invention, jitter is adjusted in each node using connection-specific frames in an ATM network, a deadline is given to each connection cell, and a cell is selected in a sequence close to the deadline, The present invention relates to a dynamic priority queue service apparatus using a per-connection frame defined by a counter interworking in an ATM network and a service method thereof,_{i, j}) Is installed and this counter (C_{i, j}) For each connection is defined by the counter interlocking in the ATM network in which individual frames are defined on a connection unit basis by performing counting on a slot basis, the dynamic priority queue service apparatus comprising: 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 dynamic priority scheduler 20 for assigning a deadline to each connected cell from the jitter adjusting means 9 to n and then servicing the cell in the order of closest deadline.
