Method, equipment and system for configuring differentiated service mode supported by multi-protocol label switching (MPLS)

Abstract

The embodiment of the invention provides a method, equipment and a system for configuring a differentiated service mode supported by multi-protocol label switching (MPLS), and relates to the field of communication. Relatively higher configurability is achieved, the problem of differentiated service mode consistency between two communication terminals can be solved, and end-to-end communication can be ensured. The method comprises that: one communication terminal performs own differentiated service mode configuration according to the application scenario of a virtual label switched path, and transmits configured differentiated service mode information comprising the differentiated service mode of the terminal to an opposite communication terminal; and after receiving the differentiated service mode information, the opposite terminal configures own differentiated service mode according to the differentiated service mode in the differentiated service mode information. The embodiment of the invention is used for the configuration of the differentiated service mode.

Description

technical field [0001] The present invention relates to the communication field, in particular to a configuration method, device and system for a differential service mode supported by MPLS. Background technique [0002] Differentiated Services (Differentiated Service, DS) defines an architecture that can implement scalable service classification on the Internet. A "service" is defined by some important characteristics when transmitting data packets through one or several paths in the same transmission direction within a network. For example, these characteristics may include throughput, delay, delay jitter, etc., and may also refer to their relative priority in obtaining network resources. [0003] Multi-Protocol Label Switching (MPLS) is a system for fast data packet switching and routing, which provides capabilities such as destination, routing, forwarding and switching for network data traffic. More specifically, it has mechanisms for managing various forms of communic...

Problems solved by technology

[0006] However, the deployment of this differential service mode is poor, and to a certain extent, it is difficult to achieve the consistency of the differential service mode between the two ends of the communication, because different differential service modes are an end-to-end concept, which requires Ingress LSR (Ingress Label Switching Router, ingress label switching router) and Egress LSR (Egress Label Switching Router, egress label switching router) cooperate closely, and this method is to configure their own differential service mode at the opposite end of mutual communication. When the network scale is relatively large When using physical ports, it is difficult to solve the consistency problem of the differential service mode between the two ends of communication by configuring physical ports, and the LSP (Label Switched Path, Label Switched Path) tunnel has the characteristics of dynamic establishment and is not bound to a specific physical port. It is more difficult to solve the consistency problem of the differential service mode between the two ends of the mutual communication by the configuration of the physical port.

[0007] Some equipment suppliers configure corresponding differential service modes according to different application scenarios in some logical entities, such as VPN (Virtual Private Network, virtual private network) and TE (Traffic Engineering, traffic engineering) interfaces; but due to When the logical entity configures the differential service modes of the two ends of the mutual communication, it configures the differential service modes of the two ends respectively. consistency problem
