提供稳健的内容递送沿着高效的无线资源使用对于下一代无线网络是重要的。为了实现这一目标，我们提出了一个积极的内容缓存计划，利用交通系统，特别是火车。在我们的系统中，我们将具有CCN功能的内容服务器放置在每个火车和车站。视频内容的片段在列车到达车站之前由车站服务器预先缓存。列车在车站停靠时通过高速无线传输接收内容。我们开发了一个基于IP和CCN混合协议的原型系统。我们通过现场实验评估其性能，并与使用蜂窝网络的传统CDN场景进行比较。评估的结论是，我们的系统可以实现高速和高可靠的视频传输，而不会冻结。
Providing robust content delivery along with efficient wireless resource usage is important for next generation wireless networks. To achieve this, we propose a proactive content caching scheme utilizing transportation systems, especially trains. In our system, we place content servers with CCN capability to every train and station. Segments of video contents are pre-cached by the station servers before trains arrive at stations. Trains receive the contents via high-speed wireless transport while they stop at the stations. We develop a prototype system based on IP and CCN Hybrid protocols. We evaluate its performance by field experiment and compare with traditional CDN scenarios using cellular networks. Evaluations conclude that our system can achieve high-speed and high-reliable video delivery without freezing.
