【摘要】：信息中心网络(ICN,Information Centric Network)顺应网络应用模式的转变,实现内容提供者和接收者的解耦,内容名字和存储位置的解耦,内容和名字的绑定以及泛在的内置缓存。为了简化内容块的命名机制、降低缓存协同复杂度、提高网络多路径的有效利用,本论文提出了基于网络编码的内容中心网络。内容中心网络(CCN,Content Centric Network)和网络编码都致力于解决内容分发问题,分别通过缓存和计算来节省带宽。本论文依托江苏省未来网络前瞻性研究项目子课题《基于网络编码的内容中心网络》,围绕如何在内容中心网络中融合网络编码,完成以下几个方面的工作:(1)对内容中心网络和网络编码相关研究内容做了细致分析并分别概述。(2)提出了网络编码与内容中心网络的融合方案,完成了基于网络编码的内容中心网络模型NC-CCN的设计。(3)针对提出的NC-CCN模型做了大量仿真实验,并与CCN的性能做了详细对比分析。(4)采用仿真通过验证的设计方案,实现了 NC-CCN原型系统的设计与实现。本论文研究结果发现,融合网络编码的NC-CCN能够消除CCN中细粒度命名问题、有效利用多路径进行转发、减少缓存协同的复杂度、简化传输机制。仿真结果表明:NC-CCN各方面的性能在合适策略的选择下表现出比CCN更好的性能收益。最后,本论文以通过仿真验证的设计方案为基础,进一步在IP网络上以覆盖网方式设计和实现了原型系统,验证了功能的正确性。
[Abstract]:Information Center Network (ICN,Information Centric Network) adapts to the transformation of network application mode, implements decoupling of content provider and receiver, decoupling of content name and storage location, binding of content and name, and ubiquitous built-in cache. In order to simplify the naming mechanism of content blocks, reduce the complexity of cache collaboration and improve the efficient utilization of network multipath, this paper proposes a content center network based on network coding. Content-centric network (CCN,Content Centric Network) and network coding are dedicated to the problem of content distribution by caching and computing to save bandwidth respectively. This paper relies on the future network forward-looking research project of Jiangsu Province, "content Center Network based on Network coding", and focuses on how to fuse network coding in content Center Network. The main works are as follows: (1) detailed analysis and summarization are made on the content center network and network coding related research contents. (2) the fusion scheme of network coding and content center network is put forward. The design of content center network model (NC-CCN) based on network coding is completed. (3) A lot of simulation experiments are done for the proposed NC-CCN model. And the performance of CCN is compared and analyzed in detail. (4) the design and implementation of NC-CCN prototype system is realized by using the design scheme of simulation and verification. In this paper, we find that NC-CCN fusion network coding can eliminate the fine-grained naming problem in CCN, effectively use multi-path to forward, reduce the complexity of cache collaboration, and simplify the transport mechanism. The simulation results show that the performance of NC-CCN is better than that of CCN under the choice of appropriate strategy. Finally, based on the design scheme verified by simulation, the prototype system is designed and implemented by overlay network on IP network, which verifies the correctness of the function.
