Method and apparatus for TCP with faster recovery

A method of setting a parameter for a transmission control protocol used by a source to transmit data to a receiver across a connection through a computer network, comprising:

• receiving by the source from the receiver a first acknowledgment at a first time and a second acknowledgment at a second time;
• determining an elapsed time using the difference between the first time and the second time;
• determining a quantity of data transmitted by the source to the receiver using the first acknowledgment and the second acknowledgment;
• generating a sample bandwidth share using the quantity of data transmitted and the elapsed time;
• generating an estimated end-to-end bandwidth share available to the connection by filtering the sample bandwidth share;
• and
• performing the following if congestion is detected on the computer network:
• generating a congestion window using the estimated end-to-end bandwidth share;
• and
• generating a slow start threshold using the estimated end-to-end bandwidth share.

An apparatus for setting a parameter for a transport protocol used by a source to transmit data to a receiver across a connection through a computer network, comprising:

• a processor;
• and
• a memory coupled to the processor, the memory having processor executable program instructions stored therein, the program instructions including:
• generating an estimate of end-to-end bandwidth share available to the connection through the computer network;
• and
• setting the parameter using the estimated end-to-end bandwidth share for the connection if congestion is detected on the computer network.
