Abstract: A system includes a first processor configured to analyze packets received over a communication protocol system and determine one or more congestion indicators from the analysis of the data packets, the one or more congestion indicators being indicative of network congestion for data packets transmitted over a reliable transport protocol layer of the communication protocol system. The system also includes a rate update engine separate from the packet datapath and configured to operate a second processor to receive the determined one or more congestion indicators, determine one or more congestion control parameters for controlling transmission of data packets based on the received one or more congestion indicators, and output a congestion control result based on the determined one or more congestion control parameters.

Abstract: Congestion control by adding a congestion signal tag header to each of one or more transmission packets prior to transmission of the transmission packets by the first node to a second node, the congestion signal tag header specifying one or more congestion signal types and, for each of the congestion signal types, specifying a congestion signal value by providing an initial congestion signal value for the congestion signal value; receiving one or more return packets generated by the second node in response to receipt of the transmission packets, the return packets including a congestion signal reflection header having one or more return congestion signal values, and the return congestion signal values corresponding respectively to the congestion signal types; and determining whether transmission rate control is necessary based on the return congestion signal values.
