چکیده

Traffic management and congestion control are key issues in ATM networks. Congestion control schemes promises effective traffic management and it uses feedback information from the network to specify the maximum rate at which each source can transmit cells in to the network. In this paper, we considered an Explicit Forward Congestion Indication (EFCI) Congestion scheme, developed by ATM forum for ATM networks. This scheme has cell drop problem at intermediate switch and allowed cell rate at source terminals oscillates from lower values to higher values and vice versa. An enhancement to EFCI scheme is proposed. The simulation results shows that enhanced EFCI scheme gives better results than basic EFCI scheme.
