Abstract

A client device configured to access a remote device via a communication network. The client device is configured to: a) detect a termination of a network connection to the remote device and b) in response to detecting the termination of the network connection, record an idle time duration associated with the network. The client device repeats a) and b) until a plurality of idle time durations have been recorded. The client device then determines from the plurality of idle time durations a timeout value associated with the network and sets a transmission period of a keep-alive signal transmitted from the client device to the remote device based on the determined timeout value. The client device transmits the determined timeout value and information identifying the network to a timeout value server that may be accessed by other client devices.
