【摘要】：信息中心網絡(ICN,Information Centric Network)順應網絡應用模式的轉變,實現(xiàn)內容提供者和接收者的解耦,內容名字和存儲位置的解耦,內容和名字的綁定以及泛在的內置緩存。為了簡化內容塊的命名機制、降低緩存協(xié)同復雜度、提高網絡多路徑的有效利用,本論文提出了基于網絡編碼的內容中心網絡。內容中心網絡(CCN,Content Centric Network)和網絡編碼都致力于解決內容分發(fā)問題,分別通過緩存和計算來節(jié)省帶寬。本論文依托江蘇省未來網絡前瞻性研究項目子課題《基于網絡編碼的內容中心網絡》,圍繞如何在內容中心網絡中融合網絡編碼,完成以下幾個方面的工作:(1)對內容中心網絡和網絡編碼相關研究內容做了細致分析并分別概述。(2)提出了網絡編碼與內容中心網絡的融合方案,完成了基于網絡編碼的內容中心網絡模型NC-CCN的設計。(3)針對提出的NC-CCN模型做了大量仿真實驗,并與CCN的性能做了詳細對比分析。(4)采用仿真通過驗證的設計方案,實現(xiàn)了 NC-CCN原型系統(tǒng)的設計與實現(xiàn)。本論文研究結果發(fā)現(xiàn),融合網絡編碼的NC-CCN能夠消除CCN中細粒度命名問題、有效利用多路徑進行轉發(fā)、減少緩存協(xié)同的復雜度、簡化傳輸機制。仿真結果表明:NC-CCN各方面的性能在合適策略的選擇下表現(xiàn)出比CCN更好的性能收益。最后,本論文以通過仿真驗證的設計方案為基礎,進一步在IP網絡上以覆蓋網方式設計和實現(xiàn)了原型系統(tǒng),驗證了功能的正確性。
[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.
