METHOD AND DEVICE FOR CONTROLLING ADMISSION TO A GUARANTEED QUALITY OF SERVICE IN A MPLS NETWORK

摘要

The invention concerns a method and a device for controlling admission to a guaranteed quality of service in a MPLS network (150), the MPLS network consisting of at least one input peripheral router (100) and one output peripheral router (120), the data flows being transported in the MPLS network through tunnels. The invention is characterized in that the input peripheral router receives request from a client (180a) for setting up a guaranteed quality of service in the MPLS network, obtains traffic engineering parameters corresponding to the service requested by the client, determines whether the creation of a tunnel for transporting the data flow(s) related to the guaranteed quality of service between the input peripheral router and the output peripheral router is possible in the MPLS network and transfers to the client a message of denial of the request of the client for setting up a guaranteed quality of service in the MPLS network if it is not possible to create a tunnel for carrying the data flow(s) related to the guaranteed quality of service between the input peripheral router and the output peripheral router in the network.
