Abstract: A system and method is disclosed for routing a stream between several nodes, Ni, forming a network. The stream is transmitted by a source and is intended for one or more destinations taking account of the mobility requirements of the users and of the network nodes. The network nodes have the following characteristics: a node, Ni, of the network comprises a service module, xSVi, one or more transfer gateways, xTGi, a function LOC suitable for generating for each service a routing table used at the request of the service modules, xSVi. A server LOC is connected, for a given service, via a service node, SNGi, to the other routing modules LOCi.

Abstract: Method and system for routing data streams in a meshed system, in which use is made of multitopology routers each provided with an intelligent module and wherein at least one step is implemented which takes account of the flow objectives associated with a data stream, the intelligent module associated with each multitopology router determines the proportion of resources reserved for the streams established for the various operational importances and a metric of links is calculated for each of the topologies, and each multitopology router driven by its intelligent module determines a routing table for each topology.

Abstract: Procedure and device for managing the quality of service hop-by-hop in a packet-based communications network comprising several arteries linked together by a router, the network supporting a signalling protocol. The procedure comprises at least at each router a step of reserving the resources on the arteries gradually and a step ensuring once the communication has been established that the packets of one and the same connection follow the path between the sending source and the destination on which the resources have been reserved.

Abstract: System for dynamically controlling equipment in a communication system taking into account the dynamics associated at least with the mobility of the users (authentication and affiliation of services), service quality requests transmitted by the users of the telecommunication network, the availability of the resources of the system comprising at least one control module comprising at least: a control block comprising: a control component ACS adapted to process the authentication of users connected to the network, dynamic configuration of the IP addresses, management of authorizations for service requests from users, configuration of the network components according to the authenticated users, a control component LOC for the process of user affiliation, server mobility, user location and the application-oriented service routing, a control component QSM adapted to process service quality management on the highways of the network.
