Problems solved by technology

In order to ensure the security of the VPN, in a user site, it is often necessary to specify that only users who meet specific identity requirements have the right to connect to the public network, so it is difficult to implement the method of using the above interface to control the access rights of private network users

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the drawings and embodiments:

[0032] Referring to Figure 1, Figure 1 depicts a simple VPN network structure, in which a PE111 of the VPN service provider backbone network 11 is connected to CE121 of VPN12, and users of VPN 12 use PE111 to forward data packets to access the public network and pass through a VPN The private network interface bound to the routing and forwarding instance, that is, the interface connected to CE121 on PE111, controls users of VPN12 to access the public network; another PE112 of VPN service provider backbone network 11 in Figure 1 is connected to CE131 and CE132 of VPN13, respectively. VPN13 users access the public network through PE112 forwarding data packets, and respectively use the private network interfaces bound to the VPN routing and forwarding instance, that is, the interfaces connected to CE131 and CE132 on PE112 to control VPN13 users' access to the pub...

Abstract

The invention provides a method of controlling private network user access right, including the steps: configuring identification information of data message allowing virtual private network (VPN) user to access public network; judging if the information carried by the above data message matches with the identification information: if yes, transmit the data message; otherwise discard it. The invention can control the user to access the public network according to the IP address carried by the data message, thus make the control more flexible and fully meeting actual requirement of the user and simultaneously, examining the VPN route transmission instance that the data message belongs to and strengthening the safety of public network access.

Description

Technical field [0001] The invention relates to a control technology for network access, in particular to a method for controlling the access authority of a private network user. Background technique [0002] With the development of the network, especially the network economy, many enterprises have put forward higher demands for their own network construction, which are mainly manifested in the flexibility, security, economy, and scalability of the network. In this context, Virtual Private Network (VPN, Virtual Private Network) has won the favor of more and more enterprises with its unique advantages. A private private network constructed using a public network is called a virtual private network. Using this technology can ensure the security and proprietaryness of private data in the public network, while providing management, scalability and flexibility. VPN is divided into three types: remote access virtual network (Access VPN), enterprise internal virtual network (IntranetVPN...
