APPARATUS OF THE STATIC PRIORITY QUEUEING DISCIPLINE USING THE PER-SESSION FRAME DEFINED BY THE SYNCHRONUS COUNTER OPERATION IN ATM NETWORKS BY DISTRIBUTED CONTROL MECHANISM

摘要

The present invention performs the function of the jitter controller by alternately serving each frame by using two logically divided FIFO queues for each connection, and each FIFO queue drives a corresponding switch by a distributed control scheme to give the highest priority. A distributed priority control priority queue service apparatus using frame-by-connection frames defined by counter interworking in an ATM network in which a cell is automatically selected. In the fixed priority queue service apparatus which adjusts, gives high priority to frames of each real-time connection in order of small size, and then selects and serves a cell to serve according to the priority, the predetermined priority from the demux 29 The real-time cell data of the virtual channels VC1 to VCn is input to two FIFO queues separated by logical connection units. The jitter is controlled by selectively serving the unit, and the distributed control method fixed priority service queue is configured to automatically select and service the highest priority cell among the cell data by the corresponding distributed control method switch for the FIFO queue. 30 to n); Cell data of the virtual channel VC0, which is a non-real time connection, is input from the demux 29, and the data traffic FIFO queue 40 is provided.
