ABSTRACT:
A method and an apparatus are provided for improving or optimizing the frequency at which the keep-alive messages are sent to a network device (e.g., an Internet service platform) from a set top box (STB) connected to a router or gateway. By improving or optimizing the frequency at which these messages are sent by the STB to the network device, the amount of network bandwidth that is consumed as a result of sending keep-alive messages can be reduced. This allows a network device to remotely and asynchronously access a STB in a very efficient manner in terms of bandwidth consumption.
