随着互联网的快速发展,用户对内容信息的需求日趋明显,当前网络架构的设计已经不能满足时下服务的要求,因此,以信息为中心的未来网络的研究得以迅速发展。内容中心网络(CCN)是未来网络的研究热点之一,然而现阶段CCN的设计未深入考虑用户移动性问题。本文针对CCN网络中的移动性管理问题,提出一种基于层次路由推送的解决方案。仿真结果表明,本文所提出的方法能有效降低用户获取内容的时间及网络中消息重传数目。
With the rapid development of the Internet, the demand of users for content information has become increasingly evident. The current network architecture design can no longer meet the demands of the current services. Therefore, the research on the information-centric future network has been rapidly developed. Content center network (CCN) is one of the hot spots in the future research of network. However, the design of CCN does not take user mobility into consideration at this stage. In this paper, aiming at the problem of mobility management in CCN network, a solution based on hierarchical route push is proposed. Simulation results show that the method proposed in this paper can effectively reduce the time for users to obtain content and the number of message retransmissions in the network.
