Abstract: Disclosed is a method for automatically configuring a network address of network interfaces of communicating elements intended to form part of a home-automation system for a building and belonging to an unconfigured network part, the unconfigured network part including a head network equipment item and at least one communicating element, the network address of each network interface including a network prefix. The method is implemented subsequent to the connection of the head network equipment item to a configured communication network arranged in the form of a hierarchical network including at least two successive hierarchy levels, the method including steps of: negotiating the network prefix of the network interface of the head network equipment item; propagating the network prefix to the communicating elements belonging to the network part with a view to the automatic configuration of the network addresses of the set of network interfaces of the communicating elements.

Abstract: This home-automation system for a building comprises: home-automation equipment, distributed within areas of the building; and a communication network, to which the home-automation equipment is connected, and authorizing an inter-communication of the home-automation equipment according to a predefined communication protocol. The communication network is a hard-wired hierarchical network comprising: a first network of rank n; a plurality of sub-networks of lower hierarchical rank n?1, connected to the first network, each sub-network being associated with an area and containing at least one of the home-automation equipment items; each sub-network of the lower hierarchical rank n?1 being hooked up to the first network of rank n by a network equipment item.

Abstract: A method of managing traffic in a communication network is implemented by a network interface of a communicating element during the transmission of a message on a physical link of the network, the message including a transmission priority level. This method includes the steps of: detecting an internal state of a data link layer, as long as the internal state of the link layer does not allow the message to be sent immediately: waiting for the internal state of the link layer to reach a priority state equal to or lower than the transmission priority level, increasing the transmission priority level each time the internal state resumes a busy state signifying that a signal is present on the physical link during this wait time; sending the message when the internal state changes to a priority state equal to or lower than the transmission priority level.

Abstract: Disclosed is a communication method implemented in a home-automation system for a building including communicating elements including home-automation and network equipment, the communicating elements being connected to an unconfigured communication network, each communicating element utilizing a predefined communication protocol, and having physical and network addresses including a network prefix cut up into a plurality of addressing fields, at least one of which is not filled.

Abstract: Disclosed is a method for communicating between communicating elements forming part of a home automation system for a building, each communicating element being connected in a communication network allowing communication according to a predefined communication protocol. Each communicating element of the communication network stores a current network address in a memory of the communicating element, the current network address being used for point-to-point addressing in the communication network, and each communicating element stores at least one preceding network address of the communicating element in the memory of the communicating element.

Abstract: This method for configuring a home-automation system for a building includes a plurality of communicating elements so as to perform a plurality of home-automation functions and a communication network to which the communicating elements are connected, each communicating element including a network interface possessing a network address and implementing one or more software objects modelling this communicating element in the form of resources of at least three types: input, output and logic unit. The method includes steps of:—discovering the various communicating elements of the communication network,—mapping, in the communication network, the resources that each communicating element discovered offers,—programming the home-automation functions of the home-automation system while taking account of the mapping of the resources in the communication network.
