Embodiment Construction

[0076] The SNMP-based MPLS-VPN network topology discovery method proposed by the present invention is described as follows in conjunction with the accompanying drawings and embodiments.

[0077] Firstly, the SNMP-based MPLS-VPN network management operating environment is established; a management information base MIB is configured on each network node of the VPN network.

[0078] like figure 1 As shown, S1: the network information collection process collects MPLS-VPN configuration data information. The network information collection process accesses the SNMP management information base MIB through the application layer protocol, and collects MPLS-VPN configuration data information, wherein the MPLS-VPN configuration MIB data table information includes at least: PE router VRF table (mplsVPNVrfTable) and VRF RT table. Specific steps such as figure 2 As shown, step S101, collect the number of VRF (Virtual Routing Forwarding) configured by the device; step S102, judge whether t...

Abstract

The invention discloses a discovery method of network topology based on MPLS-VPN, relating to the technical field of network management. The method comprises the steps of: acquiring MPLS-VPN configuration data information in the process of acquiring network information; and drawing an MPLS-VPN topological graph according to the MPLS-VPN configuration data information. On the basis of the method, a system comprises an MPLS-VPN configuration data information acquisition module for acquiring the MPLS-VPN configuration data information in the process of acquiring network information, and an MPLS-VPN topological graph drawing module for drawing the MPLS-VPN topological graph according to the MPLS-VPN configuration data information. The method can automatically discover and generate the topological graph to provide visual VPN information according to the condition of the MPLS-VPN network configuration.

Description

technical field [0001] The invention relates to the technical field of network management methods, in particular to a method for discovering the topology of an MPLS-VPN network. Background technique [0002] VPN (virtual private network, virtual private network) refers to a network where customers are connected together through public facilities and using the same security policy as a private network. The VPN set up on the public network provides security, reliability and manageability like the existing private network of the enterprise. Using the public network to build a virtual private network will bring many benefits to service providers and VPN users. For service providers, by providing value-added services such as VPN to enterprises, they can establish a closer long-term cooperative relationship with enterprises, and at the same time make full use of existing network resources. For VPN users, a large amount of private line expenses can be reduced, and enterprises do ...
