METHOD FOR SETTING TUNNEL BY SERVICE CLASS OF DIFFERENTIATED SERVICE IN MPLS NETWORK BASED ON IP

摘要

The present invention Ingress (Ingress) two-step hierarchical dynamic lookup algorithm of the tunnel setup to send subscriber traffic from the router (Hierarchical Two Level Dynamic Lookup Algorithm) to (Internet Protocol) IP to set up a tunnel using based on MPLS (Multi -Protocol Label Switching) relates to how to set up the tunnel by the service class of the DiffServ (differentiated service) in the network.; How to enable the ingress router traffic tunnel according to the present invention, IP during resource allocation and tunnel set by GB-TE (Guaranteed Bandwidth Traffic Engineering) of the MPLS network based on a first process of receiving is a subscriber generated traffic .; A second step of searching the next-hop tunnel label of the dynamic look-up; A third step of determining the quality of service of the service class to which it belongs, the subscriber traffic; And it characterized in that it comprises a fourth step of the dynamic and performing a look-up to retrieve the label of the next-hop tunnel to finally select the final tunnel and transmits the subscriber traffic through it in accordance with the service quality.
