A method and an apparatus are provided for improving or optimizing the frequency at which the keep-alive messages are exchanged between a network device (e.g., network server) and a remote device (e.g., a PC) behind a router or gateway. By improving or optimizing the frequency at which these messages are exchanged, the amount of network bandwidth that is consumed as a result of the exchange of keep-alive messages can be reduced. This allows a network device to remotely access a remote device in a very efficient manner in terms of the number of keep-alive messages that are generated and processed and in terms of bandwidth consumption.
