A dynamic resource management mechanism for LAN interconnection across high-speed networks

The authors study the problem of interconnecting several local area networks (LAN) across a highspeed backbone network (HSN). Because of the important gap between the transmission rate of the HSN compared to the ones of the LAN, a risk of severe congestion appears at the interconnection router that feeds the destination LAN. They study this problem using simplifying assumptions that allow them to develop a simulation model in the form of a queueing system. Simulation sessions made in simple cases show that significant gains in network utilization can be achieved by use of a real-time closed-loop control between the interconnection routers, at the expense of only a little additional traffic. They conclude with remarks about implementation possibilities and possible cooperation with other algorithms
