【摘要】：互联网的应用方式正从以面向主机的点对点通信为主转向以海量内容获取为主.为适应这一转变,研究界提出了多种以信息/内容为中心的新型网络架构.这类网络架构中最重要的特征之一是利用网络内置缓存提高接收者驱动的内容获取的传输效率和网络资源的利用率.与传统的Web缓存、CDN缓存等相比,ICN缓存系统呈现了缓存透明化、泛在化和细粒度化等新特征,对缓存系统的建模、行为理解和优化方法都提出了新的挑战.在介绍了ICN缓存系统的新特征及带来的挑战后,首先从多方面着重阐述和比较了缓存网络的优化方法,之后对缓存网络系统的理论模型研究现状加以阐述,然后分析了仍待解决的关键问题和未来的研究方向.
[Abstract]:The application of Internet is changing from point-to-point communication oriented to mass content acquisition. In order to adapt to this change, researchers have proposed a variety of new information / content-centric network architecture. One of the most important features of this kind of network architecture is to improve the transmission efficiency of content acquisition driven by receiver and the utilization of network resources by using network built-in cache. Compared with the traditional Web cache system, the Web cache system presents some new features, such as cache transparency, ubiquity and fine-grained. It presents new challenges to the modeling, behavior understanding and optimization methods of the cache system. After introducing the new features and challenges of ICN cache system, this paper first expounds and compares the optimization methods of cache network from many aspects, and then expounds the current research situation of the theoretical model of cache network system. Then the key problems and future research directions are analyzed.
