Abstract
A method and system for controlling a plurality of pipes in a computer network is disclosed. The computer network includes at least one processor for a switch. The at least one processor has a queue. The plurality of pipes utilizes the queue for transmitting traffic through the switch. The method and system include allowing a minimum flow and a maximum flow to be set for each of the plurality of pipes and determining if excess bandwidth exists for the queue. The method and system also include linearly increasing a flow for a pipe of the plurality of pipes based on the minimum flow or the maximum flow if excess bandwidth exists and if the flow for the pipe of the plurality of pipes is less than the maximum flow for the pipe. The method and system also include exponentially decreasing the flow for the pipe of the plurality of pipes based on the minimum flow or the maximum flow if excess bandwidth does not exist and the flow is greater than the minimum flow for the pipe. Thus, the traffic through the queue is stable.
