COMPENSATED UPC/NPC METHOD FOR GUARANTEEING QUALITY OF SERVICE BY ASYNCHRONOUS TRANSFER MODE NETWORK

摘要

PROBLEM TO BE SOLVED: To actualize the compensated UPC/NPC method for guaranteeing the quality of service by an ATM network. ;SOLUTION: The UPC/NOC method for two kinds of priority traffic when implementing an UPC/NPC function for a CLP=0 cell stream first and then an PC/NPC function for CLP=0+1, implements UPC/NPC for CLP=0 by PCRA algorithm (UP₀) for the existing CLP=0 cell stream. Then UPC/NPC for the CLP=0+1 cell stream is actualized by adding a compensating circuit which uses one register -R for PCRA algorithm (P₀₊₁) for the existing CLP=0+1 cell stream. By a traffic entente where two PCRs are defined in the ATM network, MPP problems of the CLP=0 cell stream and CLP=0+1 cell stream are solved to guarantee the CLRs.;COPYRIGHT: (C)1996,JPO
