Abstract: A polymorphic network control system and a polymorphic network control system method supporting terminal mobile access. A network architecture is redesigned based on the idea of separation of an identifier from a locator. In this network mode, the three-layer protocol is no longer a traditional IP message, but a message carrying a locator and an identifier. The polymorphic SDN network controller is responsible for forwarding the data packet to a destination corresponding to a destination locator. When the network location of a mobile device is changed, the transmission connection established based on the identifier will suspend communication due to the disconnection of the physical link. When the mobile device is re-accessed and a new forwarding path is established, the transmission connection can recover communication.

Abstract: A geographical identification forwarding method for area-oriented addressing. The geographic location information is used as a transmission identification, and the communication process based on the geographical identification is realized by constructing the SDN-based geographical identification transmission architecture. In this method, a geographical identification is used instead of a traditional IP identification for network transmission, which effectively alleviates the problem of narrow waist of IP single bearing in the current network. At the same time, through a flow table decomposition design, the flow table size of the switch is effectively controlled. The method provided by the present invention can be extended to a plurality of geographical identification areas to realize large-area real-time cross-domain transmission.
