Network cutting method and device based on virtual private network

The invention discloses a network cutting method and device based on a virtual private network, and belongs to the technical field of networks. The method comprises the following steps: cutting the whole network into a plurality of virtual private networks, setting an independent access address for each virtual private network, setting to confirm the identity of a user when the user accesses the virtual private network according to the access address, and carrying out encryption operation on data transmitted on the virtual private network according to confidentiality level setting. According to the scheme, the whole network is divided into a plurality of virtual private networks, the network performance can be optimized, a security guarantee mechanism is not provided for each virtual private network, and the security of user information is improved. 本发明公开一种基于虚拟专用网络的网络切割方法及装置，属于网络技术领域。该方法包括：将整个网络切割成多个虚拟专用网络，为每个虚拟专用网络设置独立的访问地址，设置当用户根据访问地址访问虚拟专用网络时对用户的身份进行确认，根据保密等级设置对虚拟专用网络上传输的数据进行加密操作。本方案通过将整体网络切割为多个虚拟专用网络，可以优化
