内容中心网络系统及其在船联网中的应用

Content Centric Network System and Its Application in Internet of Vessels

根据信息技术发展趋势,提出将内容中心网络与现有技术结合,建设新的船基信息网络的方法。介绍内容中心网络的系统结构与工作原理,并以船基数据传输系统为研究对象建立相应仿真模型。通过分析网络的内容缓存命中率、内容服务器负载、系统传输速度及完成一次数据传输所需经过的路由跳数等性能评价指标,指出内容中心网络相比于IP网络等现有网络的优点,并验证将该技术应用在船联网中的优势与可行性。

According to the development trend of information technology,a method for building ship-based information system by utilizing the newly developed content centric network is proposed.The structure of the content centric network is described and the corresponding simulation model is built by taking the ship-based data transmission system as the research target.Extensive evaluation of the model is performed by analyzing the content cache-hit ratio,the server load,the system transfer speed,and the number of routing hops required to complete a data transfer.The simulation results show that advantages of the content centric network over conventional IP networks and verify the feasibility of applications of content centric network technology in Internet of Vessels.
