学术界和工业界都发现，如果不引入以信息为中心的网络（ICN）概念，当前的互联网通信模型就无法满足未来的高可扩展性和安全性要求。在ICN模式下，最终用户只需要关心他想要什么，而不是它在哪里。在这个原则下，提出了许多新的建议。其中，使用了两种常见的内容命名方案：一种是平面的，另一种是层次的。基于不同的命名方案，设计了具有不同特征的不同内容寻址方案。在本文中，我们提出了一种混合的内容命名方案和相应的内容寻址方案，同时利用它们的优点。在该方案中，核心网和接入网通过各自不同的功能完全分离，边缘路由器用于名称映射和内容缓存。通过这种方式，可以保证核心网的稳定性，并且可以以高效的方式为最终用户提供服务。此外，安全传输和用户隐私可以得到很好的保证。我们还基于这个新颖的想法设计了一个向后兼容的架构，以便即使在小规模环境中部署时也可以保留ICN的优势。基于所提出的模型，我们所提出的方案在两种情况下的性能进行了研究，并与基本的PURSUIT和CCN情况下的性能进行了比较。数值结果表明，在不同的情况下，我们提出的方案的效率提高，它将是一个很有前途的架构在ICN世界。
Both the academic and industrial worlds have found that the current Internet communication model fails to fulfill the future high scalability and security requirements without the Information-Centric Networking (ICN) concept introduced. Under the ICN paradigm, an end user only needs to care about what he wants but not where it is. Then many clean-slate proposals have been proposed under this principle. Of them, two common content naming schemes are used: one is flat and the other one is hierarchical. Based on different naming schemes, different content addressing schemes are designed with different features accordingly. In this paper, we propose a hybrid content naming scheme and the corresponding content addressing scheme to take their advantages simultaneously. In the proposed scheme, the core network and the access network are completely separated by their different functions and the edge router is used for the name mapping and content caching. In this way, the stability of the core network can be guaranteed and the end user can be served in an efficient way. Besides, the security transmission and user privacy can be well guaranteed. We also design a backward-compatible architecture based on this novel idea so that the ICN benefits can be preserved even when it is deployed in a small-scale environment. Based on the proposed model, the performance of our proposed scheme under two scenarios are investigated and compared with that in basic PURSUIT and CCN cases. The numerical results demonstrate the efficiency improvements of our proposed scheme under different cases and it will be a promising architecture in the ICN world.
