未来互联网中面向命名数据高变动时间局部性的高效、健壮路由机制研究

The Internet architecture that is centered around the "named data" is one of the most promising directions for the "clean-slate" evolution of the future Internet. However, the named data workload of the future Internet is featured with highly dynamic temporal locality, and for designing the Internet routing mechanism, it is very important to understand its workload. In this project, we focus on the highly dynamic temporal locality of the future Internet's workload, and seeks to make contributions in the following aspects: 1) We seek to analyze the future Internet's workload under the granularity of the named data, and present analytical model for understanding its temporal locality; 2) We seek to propose a routing mechanism that can handle the highly dynamic network workload and improve the efficiencies of the network in forwarding and caching the named data; 3) We seek to propose a light-weighted mechanism against the locality-disruptive and false-locality caching pollution attacks that are targeted on the in-network caching mechanism, and improve the resilience of the routing nodes; 4) We seek to develop a future Internet prototype testbed based on Huawei's Protocol Oblivious Forwarding (POF) SDN technology, implement our proposed methodologies and mechanisms on the testbed, and evaluate them in real world. In summary, by understanding the workload of the future Internet, designing its routing mechanism, constructing its routing nodes, and implementing the real-world prototype, this project can comprehensively promote the research of the named data oriented routing mechanism for the future Internet from theory to practice.

以命名数据为核心的体系结构是未来互联网革命式演进的重要方向，而未来网中的命名数据负载具有高变动的时间局部性特征。准确理解网络负载的时间局部性特征，是设计未来网核心路由机制的前提和关键。本项目拟围绕未来网高变动的时间局部性负载特征，从以下几个方面展开研究：1）分析命名数据块粒度下的未来网负载特征，建立命名数据的时间局部性分析模型；2）设计实现适应高变动时间局部性负载的未来网路由机制，提高网络对命名数据的转发和缓存效率；3）针对基于局部性破坏和伪局部性的缓存污染攻击，设计实现有效抵御攻击的轻量级方法，提高路由节点的健壮性；4）探索运用华为协议无感知转发（POF）软件定义网络技术搭建未来网原型试验系统的技术路线，实际检验所提出网络机制和关键技术的有效性与性能。我们希望通过本项目，从“网络负载分析”、“路由机制设计”、“路由节点构造”和“原型系统建设”四个层面，整体推动对未来互联网路由机制的研究。
