Abstract

In building building information network system, openflow is the core technology of software defined network,  Separating   building information  data plane of the network equipment in the building building information network system, SDN has super control flexibility for the building building information network system, so as to realize the flexible control of network traffic, and provide a good technical platform for IP network address hopping technology. This article analyzes the principle of address hopping technology, puts forward a new network IP address hopping system in building building information network system, and adopts the network IP address hopping strategy , which effectively solves the problem that the network IP address hopping in building information network system can not be synchronized immediately due to the unstable  building  information  network data transmission speed and other factors in building   information network system What's the matter. In this article, openflow as the core technology of address hopping module and SDN routing module are designed in detail, and the security defense system of building building information network equipment based on address hopping is constructed.
