Increasing Transmission Rate to a Remote Device In Response to Attributing Information Loss as Not Being a Result of Network Congestion

A method, comprising:

• communicating, by a particular apparatus, with a remote device over a network;
• and wherein said communication with the remote device includes:
• in response to a detected loss of previously transmitted information by the particular apparatus, increasing the rate of transmission of information by the particular apparatus in response to attributing said detected loss of previously transmitted information as not being caused by congestion based on a current queuing delay determined based on measured roundtrip delays between information sent from the particular apparatus to the remote device and an acknowledgement received by the particular apparatus corresponding to said sent information;
• and
• in response to the detected loss of previously transmitted information by the particular apparatus:
• decreasing the rate of transmission of information by the particular apparatus in response to attributing said detected loss of previously transmitted information as being caused by congestion based on the current queuing delay.

An apparatus, comprising:

• one or more processing elements and memory configured to communicate using Transmission Control Protocol (TCP) with a remote device over a network including reacting to network conditions including by modifying a congestion window (cwnd);
• wherein said communication using TCP with the remote device includes:
• determining a plurality of queuing delays based on a plurality of measured roundtrip delays for a plurality of sent information and corresponding received acknowledgements;
• distinguishing between information loss due to network congestion and infoimation loss due to another cause based on the plurality of queuing delays;
• and
• in response to an identified loss of particular information sent to the remote device and attributing the identified loss as not being caused by congestion based on one or more of the plurality of queuing delays, increasing the congestion window (cwnd).
