Delay and loss-based transport protocols: Buffer-sizing and stability

It is generally accepted that buffers, in Internet routers, should be much smaller than the currently deployed bandwidth-delay product rule. However, as yet, there is no consensus on the optimal buffer-sizing strategy. Our focus will be on the performance, with respect to sizing buffers, of transport protocols that use queuing delay and packet loss as their feedback signals for flow and congestion control. The protocols we choose for our study are Compound, Illinois, and AFRICA.
