Abstract: A method for distributed management of a catalogue of objects in a communication network comprising devices. The method comprises the step of registering local objects present in a device in a local registry managed at the level of the device, wherein a local object may formulate a request for a list of objects, and receive a collected response. The request is transmitted to the single local registry of the device hosting the local object and propagated through the local registry to distant registries. The responses are collected by the local registry and the collected response is transmitted to the local object that formulated the initial request. The invention applies in particular within the context of home communication networks.

Abstract: A method and device for implementing a method for associating communication devices capable of wireless interfacing. The method includes producing a relation between communication devices capable of wireless interfacing enabling dialogue among them exclusively. The devices comprise a single and permanent identifier, can be connected to a cable network and exchange data through the latter. The association can be modified by connecting the devices to be associated to a single cable network.

Abstract: A process for synchronization in a communications network comprising at least two buses interconnected by a wireless communications network, each bus being linked to the wireless communications network by a portal. The process comprises the steps of: determining a so-called cycle server portal whose own clock will serve as a reference for the other portals; transmitting, via each portal, a synchronization signal at a predetermined instant with respect to the start of a frame and characteristic of each portal, the frame being defined with respect to each portal's own internal clock, the synchronization signal being achieved via the insertion of a control window; and detecting, via each portal, the control windows of other portals and selecting one of the detected windows for the synchronization of the receiver portal's own clock with the clock of the cycle server portal, the selected window corresponding to a portal whose clock is already synchronized with that of the cycle server portal.

Abstract: A process and a device for determining node address correspondence in a communication network in which each node is allocated a unique address after each network reset, wherein the addresses of a given node before and after a reset may differ. The process comprises the steps, at the level of a node connected to the network, of determining network topologies based on self-identification packets received before and after network reset, and of comparing these topologies for determining correspondence among addresses of a node before and after reset.

Abstract: In a 1394 bus, during the bus reset procedure, nodes exchange some Self-id packets. The invention presents a method for a node to build the topology of the bus from the information contained in the Self-id packets. Once the node has collected all the Self-id packets, the node goes over nodes to separate parent nodes (with at least one child) and children nodes (with no child). Then by going over nodes from the smallest Phy-id to the root, one can attribute which node is connected to every port of a given node.
