Dynamic Adjustment of Receive Window Utilized by a Transmitting Device

An apparatus for controlling size of a receive window, the apparatus comprising:

• a transceiver to transmit packets over a communication channel to a receiver, and to receive acknowledgment packets from the receiver corresponding to the transmitted packets;
• one or more processors;
• and
• memory storing instructions to be executed by the one or more processors, the instructions to:
• determine a backlog parameter for the receiver in accordance with a parameter value in the received acknowledgment packets;
• reset the size of the receive window in accordance with a function of a current size of the receive window and the backlog parameter;
• and
• after the receive window size is reset, transmit packets over the communication channel to the receiver in accordance with the reset size of the receive window.

A computer readable storage medium, storing one or more programs for execution by one or more processors of an apparatus that includes a transceiver to transmit packets over a communication channel to a receiver, and to receive acknowledgment packets from the receiver corresponding to the transmitted packets, wherein the one or more programs include instructions for:

• determining a backlog parameter for the receiver in accordance with a parameter value in the acknowledgment packets received by the apparatus;
• resetting the size of a receive window in accordance with a function of a current size of the receive window and the backlog parameter;
• and
• after the receive window size is reset, transmitting packets over the communication channel to the receiver in accordance with the reset size of the receive window.

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;
• determining a backlog parameter for the receiver in accordance with a parameter value 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 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;
• 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;
• and
• transmitting packets over the network to the recipient in accordance with the size of the network window.
