METHOD FOR DIVIDING BUFFER BETWEEN QOS CLASSES IN ATM EXCHANGE

摘要

PROBLEM TO BE SOLVED: To provide a quality-of-service(QOC) inter-class buffer dividing method in an asynchronous transfer mode(ATM) exchange eliminating the necessity of turning off all buffers when specific QOS is congested at the time of excess load and capable of managing the use of accurate resources (a line band and a buffer) when a connection acceptance control(CAC) is adopted. ;SOLUTION: A buffer pool 1 is constituted of buffers BF1 to BF8 to be high speed buffer memories capable of opening a hunt in each cell. A QOS class queue is constituted of first in first out(FIFO) queue in each QOS.;COPYRIGHT: (C)1999,JPO
