中文摘要:

内容中心网络(content-centric networking,CCN)实现了基于内容的信息传输以及泛在的网络缓存功能，但是，CCN中内容名字和位置的绑定使得其应用于移动网络时面临着基于内容名字的路由收敛问题，尤其是当内容源移动时．针对此问题，提出一种基于多接口的内容源移动性管理机制．在网络中部署多接口移动内容路由器，路由器通过内向和外向接口先后执行切换，使得中断间隔时延最小．通过数学建模分析切换性能，并进一步分析切换的中断间隔时间，研究影响切换时延的主要参数．实验结果表明，通过合理配置主要影响参数信道扫描频率及移动内容路由器间距，可以提高切换性能，实现无缝切换．

英文摘要:

Content-centric networking (CCN) realizes the information delivery based on the content and in network caching universally. However, it also faces the problem of routing convergence based on the content name, which is due to the binding of content name and physical location, especially in the case of content source moving. Aiming at the problems of content source moving in CCN, the multiple interfaces-based content source mobility management scheme is proposed. The multiple interfaces-based mobility content routers are employed in the network, and these routers perform the handoff by the egress and ingress interfaces sequentially to reduce the interruption interval. The handoff performance and interruption interval are studied by the mathematical model, and the impact of critical parameters is deeply analyzed. The experimental results reveal that this proposition can improve the handoff performance and realize seamless handoff if the main parameters as channel scan frequency and distance of mobile content routers are correctly chosen.
