Dynamic Adjustment Of Receive Window Utilized By A Transmitting Device

摘要

A method of controlling size of a receive window includes transmitting packets over a communication channel from a transmitting device to a receiver, and receiving acknowledgment packets from the receiver, the received acknowledgement packets from the receiver including an advertised receive window size. The method further includes determining a backlog parameter for the receiver in accordance with the advertised receive window size, determining a queuing delay in accordance the received acknowledgment packets, resetting a size of a congestion window in accordance with a function of a current size of the congestion window and a factor proportional to the queuing delay, and resetting a size of a receive window in accordance with a function of a current size of the receive window and the backlog parameter. A network window is reset in accordance with the smaller of the size of the congestion window and the size of the receive window.

1. A method of controlling transmission of messages from a sender to a recipient over a network, comprising:
at a transmitting device:
receiving acknowledgment packets from the receiver corresponding to transmitted packets, the received acknowledgement packets from the receiver including an advertised receive window size;determining a backlog parameter for the receiver in accordance with the advertised receive window size in the received acknowledgment packets;determining a queuing delay in accordance the received acknowledgment packets;resetting a size of a congestion window in accordance with a function of a current size of the congestion window and a factor proportional to the queuing delay;resetting a size of a receive window in accordance with a function of a current size of the receive window and the backlog parameter, wherein the receive window has a dynamically determined size, distinct from the advertised receive window size in the acknowledgment packets received from the receiver;comparing the size of the congestion window and the size of the receive window;resetting a size of a network window in accordance with the smaller of the size of the congestion window and the size of the receive window; andtransmitting packets over the network to the recipient in accordance with the size of the network window.
