Patent ID: 7006448

Claim:
A system for measuring network round trip time, comprising: a client computer adapted for communications with a server computer, the client computer including: a processor; memory coupled to the processor containing definitions identifying fast-response operations initiated by an application program running on the processor; a monitor and analysis engine, coupled to the processor, includes an analyzer for detecting the presence of at least one of the fast-response operations where fast-response operations are certain operations associated with normal running of the application program where the application program itself is not programmed to participate in determining the round trip time, the application program requiring the transmission of a first packet to the server computer and the receipt of a second packet from the server computer in response to the first packet, and; the monitor and analysis engine calculating the round trip time when a fast-response operation is detected based on the time interval beginning with the transmission of the first packet and ending with the receipt of the second packet.
