摘要：The invention relates to a method for establishing intercommunication betweena plurality of end nodes (20-24) via a communication network. The network includesrouting nodes (10-13) arranged in a tree containing a root node (10) and branchesconnecting the nodes in pairs from the root node to the end nodes. The method includesthe following steps which are carried out by a routing node, namely: (a) a step comprisingthe reception of a request to open a two-way communication with resource reservation,originating from another routing node via a branch, known as an upstream branch, saidrequest including a bandwidth required for a flow originating from said other node,known as a downlink flow; (b) a step comprising the determination of a bandwidthrequired for a downlink flow, for a first downstream branch connected to the routingnode, as a function of the bandwidth required for the downlink flow flowing through thereceived upstream branch and of the bandwidth required for a flow originating from atleast one end node via at least a second downstream branch connected to theaforementioned routing node; and (c) a step comprising the transmission of a new

request to open a two-way connection with resource reservation to a node of the firstdownstream branch close to the routing node, which request includes the determinedbandwidth, steps (b) and (c) being repeated for all of the downstream branchesconnected to the routing node if necessary.
