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

End-user response time in a network is determined by an analyzer which measures client data transfer time, server response time, server data transfer time and, if the protocol is a TCP protocol, further measuring server network round trip time. End-user response time may be approximated by the sum of these determined times.

Method and apparatus of end-user response time determination for both TCP and non-TCP protocols
