A method, system, and computer-readable code for measuring network latency between a client computer and a server machine without requiring any additional software on the client. Network latency is a measurement that reflects the network round trip delay between a client machine and a server machine
A method, system, and computer-readable code for measuring network latency between a client computer and a server machine without requiring any additional software on the client. Network latency is a measurement that reflects the network round trip delay between a client machine and a server machine. The present invention defines a novel technique for gathering latency information. This information may be used in a variety of ways (such as making policy decisions that may limit the amount of data sent over a communications path due to detection of high latency in the network).
