Abstract

A mechanism is provided for updating a timeout value of an application in a computer system. Hardware and software configuration data of the remote computing device is determined. A local computing device in the server system is provided in accordance with the determined hardware and software configuration data. An application on the local computing device is executed for determining the execution time of the application. An echo request packet is sent to the remote computing device. A current network time delay is determined from the elapsed time between sending and receiving a response to the echo request packet from the remote computing device. The timeout value from the current network time delay and the execution time is calculated. The sending, determining, and calculating steps are repeated during execution of the application by the remote computing device for repeatedly updating the timeout value using the calculated timeout value.
