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.

Methods and apparatus to determine network delay with location independence from retransmission delay and application response time

Network monitoring method and apparatus determines the zero window event data transfer delay, reporting the amount of data transfer delay caused thereby. Non-data-transfer-delaying zero window events can be separated from those causing actual delay, allowing reporting of actual delay events separate from non-delay causing events.

Method and apparatus to determine the amount of delay in the transfer of data associated with a TCP zero window event or set of TCP zero window events
