摘要:

海洋数据传输网络与陆地网络相比具有以下明显特征:网络边界和路径以及通信资源的高度动态性和不确定性、通信介质的异构性和节点性能的非对称性、海洋通信网络资源构成的复杂性和能力局限性以及海洋空间网络用户构成的复杂性和大流动性及低密度分布等。针对上述特点,从业务特征、网络构成、网络特点、体系架构方面探讨海洋数据传输网络体系,重点指出体系架构面临的 5 个方面挑战,包括自适应性、智能组网、透明传输、漫游支持、安全传输。

关键词: 海洋数据传输网络, 网络体系架构, 海洋互联网

Abstract:

Marine data transmission networks are different from terrestrials in the following aspects: high dynamics and uncertainties in network boundary, network path and communication and networking resources, heterogeneities of communication media and asymmetric communication performance, complexity of marine communication network resources with limited capabilities and ability, and high complexity and mobility of marine users with low distribution densities etc.In view of the above peculiarities for communication network in the marine space, an SM for marine data transmission network was studied from the aspects of business characteristics, network composition, network characteristics and architecture, and five challenges faced by the architecture were focused on, including adaptability, intelligent networking, transparent transmission, roaming support and secure transmission.

Key words: marine data transmission network, network system architecture, marine internet
