  • Methods and apparatus to determine network delay with location independence
    Patent number: 11153220
    Abstract: The techniques disclosed herein determine a location independent network delay via a network monitoring device. Such techniques particularly include determining various delays such as a zero window delay, an advertised window delay, and a congestion window delay (including slow start delays).
    Type: Grant
    Filed: March 6, 2018
    Date of Patent: October 19, 2021
    Assignee: AirMagnet, Inc.
    Inventors: Craig Odell, Daniel Prescott, Douglas M. Roberts, Daniel Draper, Jason Liptak

  • Methods and apparatus to determine network delay with location independence from retransmission delay and application response time
    Patent number: 9419876
    Abstract: The techniques disclosed herein determine a location independent network delay, via a network monitoring device. Such techniques particularly include determining various delays caused by retransmission in instances of lost data segments and application response time.

  • METHOD AND APPARATUS OF MEASURING TCP NETWORK ROUND TRIP TIME
    Publication number: 20090296589
    Abstract: Network round trip time is measured as an initial value at a start of a network communication flow. If sufficient data is available subsequently during a communication flow, subsequent network round trip time value determinations are made, without TCP stack overhead and time out values being included in the determined value.
