Problems solved by technology

[0014] Method 2 realizes the management of CE devices in BGP / MPLS VPN, but since each CE device has joined Supervision VPN, the IP address of each VPN link in Supervision VPN cannot be on the same network segment. This obviously does not meet the basic theoretical requirements of VPN. RFC2547 clearly stipulates that the IP addresses of different VPNs can be the same
Moreover, since each CE device in the VPN joins the Supervision VPN, all CE devices lose the meaning of VPN isolation from the MCE device, which poses a security risk

Embodiment Construction

[0050] The core of the present invention is to establish a proxy relationship between CE (user edge) equipment and PE (operator edge) equipment, and the network side management terminal transmits the management information to the PE equipment acting as the CE equipment through the public network route, and the PE equipment according to The management information transmitted by the management terminal manages the CE equipment it acts as an agent.

[0051] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention and taking NSM (Network Service Management System) as an example of the management terminal on the network side.

[0052] The present invention proposes a brand-new solution for managing CE devices in a private network at the network operation level, and provides a brand-new method for NSM to manage CE devices in a BGP / MPLS VPN. The realization principle is shown in Figure 4.

Abstract

The invention provides a client edge (CE) device managing method and system. And the kernel of the method: building agency relation between CE device and PE (provider edge) device; network side managing end transmits management information through public networt route to the PE device; the PE device manages the CE device according to the received management information. And the invention fully uses the existing network resources to make managing end, such as NSM, able to safely, effectively and short-cut manage the CE device, avoiding occupying network device resources, increasing routing configuration complexity, hidden troubles in network, etc; thus implementing the purposes of enhancing network safety, perfecting networ side mangement mechanism of CE device, raising CE device managing efficiency, and reducing CE device managing cost.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for managing user edge equipment. Background technique [0002] BGP / MPLS VPN (Border Gateway Protocol / Multiprotocol Label Switching Virtual Private Network) was proposed by E. Rosen and Y. Rekhter in 1999, and finally formed RFC2547. BGP / MPLS VPN is a VPN provided by operators, referred to as PP VPN. [0003] The VPN device in BGP / MPLS VPN is located on the network side, and the operator provides VPN services for users. The user equipment does not need to be aware of the VPN, as long as it is connected to the PE equipment provided by the operator. [0004] The basic structure of MPLS-based VPN is shown in Figure 1. [0005] In Figure 1, MPLS-based VPN mainly consists of CE (Customer Edge) equipment, PE (Provider Edge) equipment and P (Provider) equipment. CE equipment is an integral part of the user network, and has an interface directly conne...
