Method and device for processing MPLS message

Abstract

The invention discloses a method and a device for processing a multiprotocol label switching (MPLS) message, which are applied to an MPLS message processing system comprising an interface board and a main control board, wherein at last one of the single boards serving as the interface board and the main control board supports the MPLS. The method comprises the following steps of: configuring a proxy mode for processing the MPLS message for the single board which does not support the MPLS; and when the single board not supporting the MPLS receives the MPLS message, forwarding the MPLS message to a corresponding single board supporting the MPLS for processing according to the proxy mode configured to the single board. By using the device and the method, the single board not supporting the MPLS can realize the forwarding of the message based on the MPLS so as to improve the utilization ratio of the single board resource.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a method and device for processing an MPLS message. Background technique [0002] MPLS (Multiprotocol Label Switching, Multiprotocol Label Switching) is an emerging IP backbone network technology. MPLS introduces the concept of connection-oriented label switching on the connectionless IP network, combines the third-layer routing technology with the second-layer switching technology, and gives full play to the flexibility of IP routing and the simplicity of layer-2 switching. [0003] The MPLS system has a variety of label distribution protocols, and LDP (Label Distribution Protocol, label distribution protocol) is a widely used one among these protocols. The LDP protocol defines the process of negotiating the meaning of labels between LSRs (LabelSwitched Routers). Labels are used for data forwarding between two LSRs. LSR is the main processing unit in MPLS t...

Problems solved by technology

[0007] In the existing implementation scheme, only the single board that supports MPLS feature can establish LDP session connection, and the single board that does not support MPLS feature, although the configuration can deliver the LDP protocol, but the LDP protocol cannot be established

In the MPLS environment, there are few single boards supporting MPLS features, and the price is relatively expensive.

In this case, if an LDP session connection can only be established with a board that supports the MPLS feature, then the resources of the board that does not support the MPLS feature, such as rich port resources and rich QACLs (or ACLs, that is, Access Control List) resources, etc.
