TRANSMISSION CONTROL PROTOCOL (TCP) CONGESTION CONTROL USING TRANSMISSION DELAY COMPONENTS

摘要

According to the present disclosure, methods and apparatus are provided to improve the Transmission Control Protocol (TCP) for data such as delay sensitive or bursty data. A maximum send window is adjusted using forward queuing delay and maximum bandwidth parameters. Reverse queuing delay and the number of packets drops are not factored into generation of the maximum send window. Network buffer occupation is bounded and a congestion window is effectively varied using rate shaping and gradual size increases based at least partially on the number acknowledged packets.

1. A method for performing congestion control using a transmission control protocol (TCP), the method comprising:
determining a forward delay component of a round trip time associated with sending data associated with a flow from a source node and receiving an acknowledgment from a destination node using the transmission control protocol (TCP); determining a maximum window based on at least: (i) the forward delay component; (ii) a minimum round trip time observed between the source node and the destination node; (iii) a previous congestion window for sending the data from the source node to the destination node; (iv) a maximum bandwidth between the source node and the destination node; and (v) a target buffer amount for the flow to consume; and transmitting data using the maximum window.
