Abstract
The present invention relates to IP networks and, more particularly, local area networks, for example home networks. It concerns the manner in which devices connected to such networks obtain and update knowledge of the other compatible devices connected to the network. To do this, the invention is based on a finite-state machine, comprising connected, disconnected and standby states. The changes of state take place on receipt of messages, requests or replies from the other devices, or on expiry of timers in the absence of receipt of messages.
