[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.
