Current studies have found that electromagnetic waves propagate in both positive and negative directions on the surface of magneto-optical media, and even have unidirectional propagation characteristics. This unique physical phenomenon has attracted the attention of many scholars in the industry. Through the derivation and theoretical analysis of vector potential equation, scalar wave equation and dielectric wrapped conductor waveguide, the existing TM mode and TE mode are shown. Then the millimeter wave energy is effectively radiated by the horn antenna to achieve a high efficiency coupling device. The electromagnetic energy is gathered on the surface of the conductor and transmitted along the conductor. At last, the validation of surface wave transmission is realized through experiments, which proves its authenticity.

This paper mainly introduced a congestion management based on Open-flow to solve the problem in the traditional routing strategies. When the congestion happens, the routers cannot fully use the resource of the whole network to reroute the link in congestion in traditional routing strategies. Due to this reason, traditional strategies cannot solve the congestion problem effectively. In network working under open-flow, the controller of whole network is in charge of the routing management about the whole network resources and can use them to effectively solve the problems. This management takes the advantage of Openflow that can monitor and control the whole network data strings and topology map, and solve the congestion problem more proficiency than other algorithm. In this way, it can solve the congestion problem.What's more, the service qualities will be maintained, and the throughput of network and resources utilization will be improved at the same time.
