Abstract
A method of creating a tunnel for transporting at least one data flow in a label-switched telecommunication network, the telecommunication network comprising at least one ingress edge router, a server able to define tunnels, called static tunnels, in the telecommunication network based on traffic forecasts in the telecommunication network. The method includes the steps, performed by an ingress edge router receiving an admission request from a client to transfer a data flow in the telecommunication network, of determining whether a static tunnel defined by the server in the telecommunication network is able to transport the data flow, creating a tunnel, called dynamic tunnel, able to transport the data flow in the telecommunication network if no static tunnel defined by the server is able to transport the data flow.
