Gateway-to-gateway level congestion control in high speed backbone networks

The authors investigate the performance of a congestion control scheme for an interconnected network where several local area networks are connected to a high speed backbone network via gateways. In such a network, traffic congestion may occur due to the difference of transmission speed and/or workload between the high speed backbone and the lower speed LANs. To release congestion and to obtain high throughput, the authors have previously proposed a congestion control scheme and have evaluated the performance via simulation. Since the scheme suites the short-distance backbone, it may cause performance degradation in high speed delay-product networks. The authors introduce a simple buffering technique to the previous scheme in order for it to survive in the high speed environment
