摘要
SDN具备集中控制和协同、可编程、虚拟化和开放性四个显著特点,它满足了移动网络需同时操作多种无线技术的迫切要求.SDN在蜂窝移动网络中提出了Cell SDN、Soft Cell、SoftRAN以及OpenRadio应用方案,在园区/企业移动网络中提出了OpenRoads、Odin、Open API以及OpenRadio解决方案.但SDN也存在着硬件支持不够、网络风险大以及协议缺陷等不足.
It meets the urgent needs of mobile network to operate more than one kind of wireless tech- nologies simultaneously. Concerning cellular mobile network, SDN offers application schemes of CellS- DN, SoftCell, SoftRAN and OpenRadio and regarding park/enterprise mobile network, SDN provides solutions of OpenRoads, Odin, OpneAPI and OpenRadio. However, there also exist defects like insuf- ficient hardware supports, high-risk network, imperfect protocol, etc, in SDN.
