ABSTRACT:
Calculating the roundtrip delay between first and second computers due to the latency of a routing server. The first computer receives an incoming message from the second computer via the routing server. The incoming message includes incoming time information indicative of processing time at the second computer and outgoing time information indicative of a time when a first outgoing message was sent by the first computer. The first computer calculates an observed roundtrip time indicating the routing server latency for a first outgoing message and the incoming message as a function of a time when the first computer received the incoming message, the outgoing time information, and the incoming time information.
