The invention discloses a configuration-free WiFi network system based on an OpenFlow protocol and a networking method, which realize the networking of the free-configuration WiFi of a campus network. The networking method comprises steps of constructing a wired network based on a controller and an OpenFlow interchanger, deploying wireless access points and providing a WiFi access according to a communication range, wherein each access point is directly connected to the terminal of the OpenFlow interchanger, a mobile host senses the moving state and initiatively chooses an access point based on the intensity of the signal, and all the server resources are directly connected to the OpenFlow interchanger. The invention has characteristics of free configuration, mobile communication and easy deployment.
Description
technical field [0001] The invention relates to a design method of a WiFi campus network based on the OpenFlow protocol, a configuration-free access method for a mobile host, and a method for maintaining an uninterrupted session when a mobile host roams in a campus network, belonging to the technical field of network data communication. Background technique [0002] WiFi works in unlicensed wireless spectrum and has the characteristics of low cost and high speed. WiFi technology has limited coverage and needs to rely on related facilities to provide end-to-end connection control at the network layer. Currently, a single-hop wireless local area network architecture with facilities is widely used, and multiple access points (AccessPoints, APs) are connected through a layer 2 switch. Each AP configures the DHCP service to automatically assign an IP address to the mobile host. Literature [1] analyzed the problem of user authentication, and proposed a seamless mobile solution u...
