Abstract:
1. 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 able to create dynamic tunnels and a server able to create static tunnels in the telecommunication network, the static tunnels being created based on traffic forecasts in the telecommunication network, said method comprising: receiving, at an ingress edge router, an admission request from a client to transfer a specified data flow in the telecommunication network, determining, in the ingress edge router, whether there exists a static tunnel defined by the server in the telecommunication network that is able to transport the data flow specified in the admission request, and creating, using the ingress edge router, a dynamic tunnel able to transport the data flow in the telecommunication network if there is no static tunnel defined by the server that is able to transport the data flow.
