Problems solved by technology

[0003] MPLS (Multi-Protocol Label Switching)-VPN is widely used due to the existence of the above advantages, but after completing the configuration of VPN, it lacks the means to use network configuration information to track the existing VPN configuration. Tools are available, but few provide automatic discovery of the VPN topology

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 ...
