Embodiment Construction

[0038] The specific implementation of the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] With reference to Fig. 3 and Fig. 4, the LSP Ping connectivity detection of the present invention based on SNMP (Simple Network Management Protocol, Simple Network Management Protocol) agreement is as follows:

[0040] (a) Realize the support to the LSP Ping MIB (Management Information Base, Management Information Base) library by loading the private MIB library in the VPN PE device, and realize the standard MIB operation. The MIB library includes the entry of setting the Ping parameter and saving the Ping For the entry of the result, the SNMP agent process in the VPN PE device operates the private MIB library;

[0041] The SNMP-based LSP Ping must implement the LSP Ping MIB first. Since there is no RFC standard related to LSPPing MIB, LSP Ping MIB is a private (private) MIB designed according to actual...

Abstract

The invention discloses a connectivity detection method of MPLS VPN. Based on the SNMP agreement, a private MIB library is loaded in a PE device, and the SNMP agent process in the PE device conducts operation on the private MIB library, and the steps comprise that : (a) the user set a Ping parameter at the network management client terminal, and the SNMP agent process in the PE device sets the network element MIB library and transmits the Ping parameter to a business execution module; (b) the business execution module starts up the Ping operation according to the Ping parameter and returns the Ping result to the SNMP agent process to store the result in the MIB library; (c) the SNMP management process of the network management terminal returns the Ping result which is taken from the private MIB library to the network client terminal. The method of the invention can enable the user more conveniently to conduct the VPN business connectivity detection in the VPN business management system.

Description

technical field [0001] The invention relates to the technical field of data network communication, in particular to a method for MPLS VPN connectivity detection. Background technique [0002] MPLS (Multi Protocol Label Switch, Multi-Protocol Label Switching) technology is currently a hot network technology, which combines Layer 2 switching technology and Layer 3 routing technology together to provide a connection-oriented network infrastructure. MPLS VPN (Virtual Private Network, Virtual Private Network) refers to a virtual private network based on MPLS technology, that is, using MPLS technology to build an enterprise or a specific user group's own private network on a public IP network to realize data, voice, image, etc. and other multi-service broadband connections, combined with differentiated services, traffic engineering and other related technologies, to provide users with high-quality services. [0003] The networking mode of MPLS VPN is shown in Figure 1, including ...
