A novel priority weight-based explicit rate allocation scheme for ATM ABR services

A priority weight-based rate allocation scheme is proposed for ATM ABR services. Compared with existing ATM weight-based rate allocation algorithms, the proposed scheme is able to assure quality of service (QoS) guarantee based on its cell loss ratio (CLR) specification and actual cell rate of the application. The priority weight (PW) factor allows prioritization of application services for efficient flow control using minimum control variables and only less than 6% RM cell overheads.
