Information‐centric networking (ICN) has long been advocating for radical changes to the Internet, but the upgrade challenges that these entail have hindered its adoption. To break this loop, the POINT project proposed a hybrid, IP‐over‐ICN, architecture: IP networks are preserved at the edge, connected to each other over an ICN core. This exploits the key benefits of ICN, enabling individual network operators to improve the performance of their IP‐based services, without changing the rest of the Internet. This paper first provides an overview of POINT and outlines how it can improve upon IP in terms of performance and resilience. It then describes a trial of the POINT prototype in a production network, where real users operated actual IP‐based applications. As part of the trial, we carried out experiments to evaluate the quality of experience (QoE) for video services offered via either HLS or IPTV, using either IP or POINT as a substrate. The results from the trial verify that the IP‐over‐ICN approach of POINT offers enhanced QoE to the users of these video services, compared with traditional IP, especially under exceptional network conditions.

使用ICN上的IP改善视频QoE

长期以来,以信息为中心的网络(ICN)一直在倡导对Internet进行彻底的更改,但是这些带来的升级挑战阻碍了Internet的采用。为了打破这种循环,POINT项目提出了一种混合的IP-over-ICN IP体系结构:IP网络保留在边缘,并通过ICN核心相互连接。这利用了ICN的主要优势,使单个网络运营商可以在不更改Internet其余部分的情况下提高其基于IP的服务的性能。本文首先概述了POINT,并概述了POINT在性能和弹性方面如何改进IP。然后,它描述了在生产网络中试用POINT原型的过程,实际用户在该网络中运行基于IP的实际应用程序。作为审判的一部分,我们进行了实验,以IP或POINT为基材,评估了通过HLS或IPTV提供的视频服务的体验质量(QoE)。该试验的结果证明,与传统IP相比,POINT的IPover-ICN IP方法可以为这些视频服务的用户提供增强的QoE,尤其是在特殊的网络条件下。
