Abstract:
1. A computer-implemented method for end-to-end computer network congestion control on a network link comprising: the computer providing a specific average traffic rate guarantee to each of one or more network traffic connections, configured in accordance with a first protocol and having a particular priority whenever a bottleneck link can accommodate such a rate guarantee; the computer enabling each of one or more network traffic connections, configured in accordance with a second protocol and having a second priority, the second priority lower than the first priority, to use residual bottleneck capacity; the computer monitoring a loss event rate of a network traffic connection having the second priority to determine if the loss event rate is greater than a target loss event rate; and if the loss event rate is greater than a target loss event rate, the computer suppressing the capacity of the network traffic connection of the second priority in a controlled manner in which an adaptation gain parameter of the target loss event rate is initially set to a relatively high value and linearly decreased upon subsequent updates of the target loss event rate, wherein the capacity of the network traffic connection of the second priority is reduced to a minimal amount sufficient to determine a congestion state of the network link.
