互联网是大规模内容分发的事实上的平台，但有两个问题限制了它的可扩展性、效率和发展。首先，基于IP的互联网是以主机为中心的，并且对正在交付的内容不可知，其次，控制平面和数据平面的紧密耦合限制了其可扩展性，并且随后限制了创建用于高效内容交付的动态替代路径的可能性。在这里，我们提出了卷曲系统，利用新兴的信息为中心的网络模式，使成本效益的互联网规模的内容交付，利用组播和网络缓存。CURLING遵循软件定义的网络概念，将控制平面和数据平面相结合，采用域间逐跳内容解析机制，允许网络运营商动态执行/更改其定位内容源和优化内容交付路径的网络策略。内容发布者和消费者还可以根据他们的偏好来控制内容访问。基于这两个分析建模和模拟使用真实的域级互联网子拓扑结构，我们演示了卷曲如何支持高效的互联网规模的内容交付，而无需彻底改变当前的互联网。
The Internet, the de facto platform for large-scale content distribution, suffers from two issues that limit its manageability, efficiency, and evolution. First, the IP-based Internet is host-centric and agnostic to the content being delivered and, second, the tight coupling of the control and data planes restrict its manageability, and subsequently the possibility to create dynamic alternative paths for efficient content delivery. Here, we present the CURLING system that leverages the emerging Information-Centric Networking paradigm for enabling cost-efficient Internet-scale content delivery by exploiting multicasting and in-network caching. Following the software-defined networking concept that decouples the control and data planes, CURLING adopts an interdomain hop-by-hop content resolution mechanism that allows network operators to dynamically enforce/change their network policies in locating content sources and optimizing content delivery paths. Content publishers and consumers may also control content access according to their preferences. Based on both analytical modeling and simulations using real domain-level Internet subtopologies, we demonstrate how CURLING supports efficient Internet-scale content delivery without the necessity for radical changes to the current Internet.
