Problems solved by technology

According to the survey, the current MPLS VPN products on the market are developed based on the needs of actual application networks, and non-administrators are not allowed to modify configurations, nor can they save their own configurations for non-administrator users, especially not suitable for teaching experiments on MPLS VPN technology
[0003] After checking the existing technologies, it was found that although ZebOS Advanced RoutingSuite (ZebOS advanced routing software package) of IP Infusion supports the MPLS VPN solution of virtual routers, each router in the MPLS VPN solution needs to be installed on a host Run ZebOS software for simulation, and because it keeps the technology of MPLS and VPN modules secret, it is not convenient to flexibly perform functional verification of internal modules and centralized management and control of MPLS VPN, and it is also not convenient to realize the interactivity of experiments

Embodiment Construction

[0024] Below in conjunction with the application of the present invention in the "BGP / MPLS VPN" experiment, its implementation will be described in detail. In this embodiment, the experimenter first logs in to the page, and the system automatically assigns the IP address segment available to the experimenter to configure each virtual router, and the address segments of each experimenter do not conflict with each other. All CE, PE and P virtual router processes run on the same VPN server. Experimental environment such as figure 1 shown. Specific steps are as follows:

[0025] (1) Configure the virtual system topology: first, the experimenter adds the required routers CE1, PE1, and P1; then configures the corresponding interfaces for each router; then configures the physical connections of adjacent routers for the routers. In this way, a virtual topology within the autonomous domain (Areal) is generated. Similarly, other experimenters in this group configured the virtual top...

Abstract

The method includes steps: first, system assigns available IP address field in use for configuring each virtual router for experimenter automatically; next, constructing virtual system topology structure; then, using WEB technique starts up CE, PE, P routers on VPN server; starting OSPF, BGP, MPLS modules on virtual router to construct virtual MPLS network; configuring and stating up VRF module to construct BGP / MPLS VPN network; finally, interactivity of system is realized through WEB browser. The invention is initiated in BGP / MPLS VPN domain. Comparing with prior art, the invention provides good teaching and experiment platform. In addition, the invention is applicable to engineering emulation test and other research in new network technique.

Description

technical field [0001] The invention relates to a method in the field of network technology, in particular to an MPLS VPN online experiment method supporting large-scale multi-user concurrent access. Background technique [0002] MPLS VPN is an IP VPN (IP Virtual Private Network) based on MPLS (Multiprotocol Label Switching) technology, which applies MPLS technology to network routing and IP virtual private network implemented by label switching. It can meet a variety of flexible business needs, especially through MPLS VPN to provide enterprise users with a unified communication platform including voice, data and even video services (the so-called "triple play"). Therefore, MPLS VPN has become an important direction of network security research and Internet application. According to the survey, the current MPLS VPN products on the market are developed based on the needs of actual application networks, and non-administrators are not allowed to modify configurations, nor can...
