This paper presents an adaptive available bit rate (ABR) traffic management
scheme in asynchronous transfer mode (ATM) networks using the newly develo
ped minimal resource allocation network (MRAN). MRAN generates a minimal ra
dial basis function (RBF) neural network by adding and pruning the hidden n
eurons based on the input data and is well suited for on-line adaptive cont
rol of time varying nonlinear systems. In this paper, the ATM traffic is mo
deled using the network simulation package OPNET. The performance of MRAN-c
ontroller is compared with the conventional ABR control scheme explicit rat
e indication with congestion avoidance (ERICA) for different traffic scenar
ios such as bursty and Variable Bit Rate (VBR) traffic. Results indicate th
at MRAN-controller performs better than ERICA by keeping the queue length a
nd delay to a minimum while maintaining a higher Link utilization and throu
