内容中心网络中的泛在移动管理关键技术研究

The explosive increasing of the Internet data business hastened the study and design of the new Internet architectures based on the content-centric concept. In this way, the increasely serious challenges, when the current Internet faces the massive data, are expected to be solved, such as security, mobility and scalability. The focus of the content-centric networking transfers from "where the resource is" to "what the resource is", and the communication is directly based on the content name but not its address. However, how to solve its efficient and secure addressing in the growing mobile Internet environment, is the biggest challenge faced by the content-centric networking. Besides, how to well use the current Internet infrastructure will determine whether this new architecture can be largely deployed. This project aims to optimize the content management in the content-centirc networking, designs the credible content addressing scheme based on the DNS and its related extensions and solves the key mobility management issues faced by the content-centric networking. The most difficult and important point of this project is how to optimize the network architecture and communication scheme of content-centric networking in the mobile scenario. For this purpose, we should make full use of the "content-centric" concept on one hand, and promise its smooth evolution on the other hand. The results of this project will support the efficient management of the massive Internet data and secure content addressing in the future mobile Internet.

互联网数据业务爆炸式增长催生了以内容为中心的新型互联网架构的设计研究，以期有效解决当前互联网在面对海量数据业务时面临的日益严峻的安全性、移动性和可扩展性等挑战。内容中心网络从关注于"资源在哪里"转变为"资源是什么"，从"基于端地址的转发"转变为"基于数据内容的转发"。也正是由于这一特点，如何在当前日益繁荣的移动互联网环境中采用这种通信机制实现高效的信息获取成为内容中心网络面临的最大挑战。本项目从泛在移动需求出发，研究如何优化内容中心网络的内容管理架构，设计基于DNS及其扩展协议的内容寻址模型，并在此基础上研究内容中心网络面临的各种移动性管理问题。项目难点和关键问题是如何优化移动环境下内容组织架构和通信机制，既充分利用"以内容为中心"的优势，又保证其平滑的演进。该项目研究将为未来移动环境下的海量数据高效、可信寻址提供支撑。

互联网数据业务爆炸式增长催生了以内容为中心的新型互联网架构的设计研究，以期有效解决当前互联网在面对海量数据业务时日益严峻的安全性、移动性和可扩展性等方面的挑战。内容中心网络通过对内容直接命名，实现了基于内容名字的路由和存储。然而如何在当前日益繁荣的移动互联网环境中采用这种通信机制实现高效安全的信息获取是内容中心网络面临的最大挑战；此外，如何融合既有的互联网名址基础设施也是这种新的通信架构是否能得到大规模部署应用的先决条件。本项目从优化内容中心网络内容管理架构出发，设计了可扩展的内容可信管理体系，研究了内容中心网络面临的各种移动性管理问题，提出了内容源和内容接收者移动性管理方案，并创新性地提出了一种基于内容描述的新型内容中心网络架构。上述研究成果将为内容中心网络的进一步发展和演进提供重要支撑。
