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

摘要

The invention relates to a method and an apparatus for controlling the admission to a guaranteed quality of service service in an MPLS network (150), the MPLS network consisting of at least one input peripheral router (100) and a output peripheral router (120), the data streams being conveyed in the MPLS network by tunnels. According to the invention, the input peripheral router receives a request from a client (180a) for the establishment of a guaranteed quality of service service in the MPLS network, obtains service-specific traffic engineering parameters. requested by the client, determines whether the creation of a tunnel to convey the data stream (s) related to the guaranteed QoS service between the input peripheral router and the output peripheral router is possible in the MPLS network and transfers to the client a request rejection message from the client for establishment of a guaranteed quality of service service in the MPLS network if it is not possible to create a tunnel to convey the service related data stream (s) guaranteed quality of service between the input peripheral router and the output peripheral router in the network.
