容断网络技术在岸海数据通信中的应用研究

岸海数据通信网络向海上延伸后,带宽分布不再是分级状,而是呈岛状：岛内为高可靠连通性带宽;由于移动、干扰等条件限制,岛与岛之间为间歇性连通带宽。岸海之间是典型的岛状网络,为了不增加新的网络拓扑,增强已有网络机会通信能力,提出了容断技术覆盖网岸海通信应用模型,并设计实验床进行了性能评估,仿真对比实验结果证明了该容断网络应用模型的优点。

Application of DTN in Naval Data Communication Network

As data communication network stretches to the new reach of ocean, and network bandwidth is no longer in hierachic distribution but in island-like distribution. The bandwidth within these islands is of highly reliable connectivity; and because of the condition restriction, such as motion, jamming etc, bandwidth between these islands is of intermittent connectivity. The network between land and sea is a typical island-like network. For the purpose to add no network topology and to upgrade the opportunistic communication capability of the network, a application model of DTN overlay network in communication between land and sea is proposed, and the experiment testbed is also designed for testing the performance of this model. Simulations and comparisons prove the advantages of this DTN application model.
