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.
