An efficient ABR service engine for ATM network

In recent ATM forum activities, considerable efforts have been focused on an Available Bit Rate (ABR) service, which enables maximal link utilization in the ATM network. In this paper, we present an efficient architecture of an ABR service engine, which includes all functions required in the ABR service algorithm. The new architecture of the ABR service engine is very small in size and high speed by computing the congestion control information without cell delay.
