软件定义网络技术将网络控制与数据转发功能分离，并采用软件定义的方式实现了网络的灵活重构和敏捷管理，已成为新型网络架构发展的主流方向。针对海上通信手段异构多样、网络拓扑复杂多变、信息传输流程与协议灵活适配的应用需求，提出一种基于软件定义的海上异构网络信息传输的网络结构、互连模型、路由机制、数据转发控制方法和技术架构，并对其关键技术进行了研究。
Software defined network technology separates network control and data forwarding functions and implements flexible network reconstruction and agile management by software defined method, which has become the mainstream direction of new network architecture evolution. According to the application requirements of heterogeneous network, complex and changeable topology, flexible and adaptive information transmission, the network structure, interconnection model, routing mechanism, data forwarding control method and technical architecture based on software definition are proposed. Finally, the key techniques are studied.
