Network monitoring and analysis system under virtual machine circumstance

Abstract

The invention discloses a network monitoring and analyzing system under an environment of a virtual machine. The system comprises a network data multiplexing module, a lightweight level virtual machine manager module, a virtual machine control module, a service virtual machine module and an I / O access path optimization module, wherein the network data multiplexing module and the lightweight levelvirtual machine manager module are positioned in an operating system of a host computer, the virtual machine control module and the service virtual machine module are positioned on the operating system of the host computer; and the I / O access path optimization module is positioned in the operating system of the host computer and the service virtual machine. The network monitoring and analyzing system is based on the virtual machine and realizes the network data multiplexing of a single physical machine to a plurality of network monitoring and analyzing service programs, thereby providing a plurality of monitoring and analyzing functions for the same network data in real time, realizing safe isolation between the service programs and dynamically adjusting and distributing resource to the service programs according to requirements. The network monitoring and analyzing system overcomes the problems that the prior network monitoring and analyzing system has resource competition, low safety, instability of the system, uneasy expansion and the like.

Description

(1) Technical field [0001] The invention belongs to the technical field of computing system virtualization, and in particular relates to a network monitoring and analysis system under a virtual machine environment. (2) Background technology [0002] In the current network monitoring and analysis system, one architecture is to run multiple network monitoring and analysis service programs on one physical server. These service programs are installed on the same operating system, and the isolation between them is at the process level. The maintenance and upgrading of a single service program will affect the operation of other service programs. There is a contradiction between the different requirements of each service program on the version of the system platform environment component. When a service program fails, it may affect the normal operation of other service programs, and even cause the entire system to crash. The isolation (process level) between service programs is ...

AI Technical Summary

Problems solved by technology

In the traditional virtual machine environment, an operating system is installed in each virtual machine, and application services are run in the operating system, which will bring a lot of overhead. Frequent switching seriously reduces the performance of the entire system and the transmission efficiency of network data

These will bring problems such as difficult expansion, poor adaptability and weak reliability of the network monitoring and analysis system.
