Abstract

The invention provides a mutual exclusion access method and device applied to a network controller, and the method comprises the steps: obtaining logic network information pre-configured on a network switching server; acquiring terminal access information sent by the network switching server; querying the pre-configured logic network information according to a logic network accessed by the terminal, and creating a network switching forwarding entry; receiving a terminal message, and determining whether a destination IP of the message is matched with an IP address in a preset mutual exclusion access object or not, the mutual exclusion access object comprising a pre-configured IP address set; if not, querying the network switching forwarding entry according to the source IP of the message; and acquiring a tunnel ID in the network switching forwarding table entry, and forwarding the message based on the forwarding table entry corresponding to the tunnel ID. By means of the technical scheme, terminal network switching is rapidly achieved, and the effect of fusing multiple logic networks is achieved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for mutually exclusive access. Background technique [0002] In industries such as government, finance, and medical care, in order to ensure the security of information exchange, there are scenarios where multiple logical networks such as intranets and extranets need to be physically isolated, such as e-government extranets and the Internet, tax transfer networks and the Internet , Enterprise R&D Intranet and Internet, etc. [0003] In a traditional isolation scenario, if the internal network needs to access the external network, it is necessary to adjust the configuration of the network device or even change the physical location of the user terminal to change the internal network terminal to an external network terminal. If you want to access the internal network and external network at the same time, you need to provide two user term...
