Systems, methods, and computer program products providing feedback for network congestion management

摘要

A computer program product having a computer readable medium tangibly recording computer program logic for providing feedback in a network, the computer program product including code to receive first data and second data over the network at a receiving device, code to increment a first counter and a second counter in response to the first data and second data, respectively, code to generate a plurality of feedback signals reflecting states of the first and second counters using at least three bits, the bits defining a set of code points mapped to the states of the first and second counters so that each individual code point represents a different one of the states and each one of the states is represented by one code point, and code to transmit the plurality of feedback signals to a sending device in the network.

主权项

1. A method comprising:
receiving network congestion information at a receiver over a computer network; receiving honesty accounting information from a sender over the computer network; adjusting a first counter based on the network congestion information; adjusting a second counter based on the honesty accounting information; selecting one of N code points, the N code points being defined using a common set of at least three bits and encoding state information associated with the first and the second counter, N being an integer greater than one, where a first set of the N code points encodes state information of the first counter and a second set of the N code points encodes state information of the second counter; and sending a message to the sender over the computer network, the message comprising the selected one of the N code points.
