I've always wondered if you could incorporate damping into TCP with something like PID. So you'd have a transfer function to use the error rate as an input and adjust the transfer rate based on PID. Perhaps more CPU overhead, but we have amazing CPUs now.
- xtacy 15y agoIt's an interesting thought, and one could always make good use of more feedback to make a control loop behave nicely with respect to throughput, fairness, convergence time and stability. There have been many improved congestion control algorithms proposed with this train of thought: XCP[1], RCP[2] to name a few. One of the reasons why they have not caught on is that they require a lot of support from the network.
