Research on Network Access Control System Model Based on Virtualization Technology

With the continuous development of computer technology, virtualized network has become an indispensable part of the current social life and economic field. In the operation of computer networks, virtualization technology can effectively realize the information interaction between users and systems, or between servers and applications, and analyze and manage them through virtualization models. In addition, virtualization technology can also analyze and manage network data, thus enabling information interaction between users and servers. This paper first describes the virtualization technology, which mainly analyzes the virtualization technology based on x86 architecture. x86 architecture is mainly analyzed and studied from CPU virtualization, memory virtualization, device and I/O virtualization, and the network access control system based on virtualization technology is proposed to be studied accordingly. Secondly, this paper studies the design and implementation of network access control system based on virtualization technology, mainly analyzes the model of network access control system based on virtualization technology, and carries out detailed design of each subsystem in the system, finally realizes the whole system between different users, between servers and applicants and different types of environments, which can provide users with fast and secure and efficient services.
