Embodiment Construction

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0020] figure 2 It is a flow chart of Embodiment 1 of an access method of MPLS VPN according to the present invention, such as figure 2 As shown, the method of the present embodiment includes the following steps:

[0021] Step S201, generating service matching rules according to the user-customized MPLS VPN access service type information;

[0022] In this step, among the configured MPLS VPN access services, the user can customize some of the access services as required, so that other services are still processed according to ordinary packets, thus saving MPLS VPN resources, such as , a company handles MPLS VPN services between office A and office B, but c...

Abstract

The invention provides an MPLS VPN (Multi-Protocol Label Switching Virtual Private Network) access method and device. The MPLS VPN access method comprises generating a business matching rule according to user customized MPLS VPN access business type information; generating a static mapping relation between an MPLS VPN access business and an MPLS VPN instance according to the business matching rule; and screening out a business message which is accessed through a user customized MPLS VPN from received ordinary business messages according to the business matching rule and performing message processing on the ordinary business messages according to the static mapping relation to enable processed ordinary business messages to be MPLS (Multi-Protocol Label Switching) business messages of the user customized MPLS VPN. According to the MPLS VPN access method and device, the business message which is accessed through the user customized MPLS VPN is matched from the received messages, so that the problem that the current MPLS VPN access method is single is solved.

Description

[0001] technical field [0002] The embodiment of the present invention relates to data communication technology, and in particular to a method and device for accessing an MPLS VPN. [0003] Background technique [0004] Due to its flexibility and openness, the protocol for interconnection between networks (Internet Protocol, referred to as IP) will become the basis of the future converged network. The future network will be a converged network oriented to IP, and the converged network will be able to provide customers with new services. and experience, reduce investment costs, and enhance competitiveness. Multi-protocol label switching (MPLS) technology will be more widely used in the networks of various operators and enterprises, which will help users establish a global VPN Bring great convenience. [0005] figure 1 It is the topology diagram of MPLS network equipment, such as figure 1 As shown, the IP packet is labeled on the MPLS ingress device PE1 (Provider Edge, re...
