Response for spurious timeout

A method for responding to a spurious timeout on a network, comprising:

• restoring congestion state values, including setting a limit of data that a sending host can send over the network before receiving an acknowledgement;
• restoring a threshold value of available bandwidth prior to the spurious timeout;
• adjusting a pipe value, wherein the pipe value is based on an estimate of data outstanding on the network prior to the spurious timeout and is based on adding a maximum segment size capable of being sent by a sending host to a difference between a maximum sequence number sent and a lowest sequence number that is not yet acknowledged;
• maintaining a data flow from the sending host, wherein data is transmitted if the pipe value is less than a congestion state window;
• and
• resetting, upon receiving an acknowledgement, the limit of data that the sending host can send over the network before receiving an acknowledgement.

A computer-readable storage medium embedded with a computer executable program having at least one instruction that, upon detecting a timeout on a network, causes at least one processor to:

• adjust congestion state values including adjusting a pipe value, wherein the pipe value is based on an estimate of an amount of data outstanding in the network to a maximum segment size sent by a sending host plus a difference between a maximum sequence number sent and a lowest sequence number that is not yet acknowledged;
• maintain a data flow on the network, wherein data is transmitted if the pipe value is less than a congestion state window;
• and
• re-transmit previously transmitted data when the previously transmitted data is determined to be lost on the network.

An apparatus for spurious timeout recovery, comprising:

• a transmitter to transmit data packets;
• a transmission timer to detect a spurious timeout;
• and
• a response processor
• to adjust congestion state values by setting a limit for an amount of data that a sending host sends before receiving an acknowledgement to be twice a size of a data segment that the sending host can send,
• to maintain a data flow on a network with the adjusted congestion state values, wherein data is transmitted if a pipe value is less than a congestion state window, wherein the pipe value is based on adding a maximum segment size capable of being sent by the sending host to a difference between a maximum sequence number sent and a lowest sequence number that is not yet acknowledged, and
• to re-transmit previously transmitted data when the previously transmitted data has been deemed to be lost on the network, wherein the data flow is maintained until data is confirmed to be lost on the network.

A processor, comprising:

• means for adjusting congestion state values, said means for adjusting congestion state values including a means for adjusting a pipe value, wherein the pipe value is based on an estimate of an amount of data outstanding in a network to a maximum segment size capable of being sent by a sending host plus a difference between a maximum sequence number sent and a lowest sequence number that is not yet acknowledged;
• means for maintaining a data flow on a network in accordance with the adjusted congestion state values, wherein data is transmitted if the pipe value is less than a congestion state window;
• and
• means for re-transmitting previously transmitted data when the previously transmitted data has been deemed to be lost on the network.
