本文考虑ICN（信息中心网络）CCN（内容中心网络）中的视频和音频传输，其中每个中间节点都可以缓存内容。 LCE（Leave Copy Everywhere）被称为通用缓存决策策略。但是，由于LCE在所有中间节点都进行缓存，因此中间节点的缓存可以是重复的。因此，人们提出了各种消除冗余的缓存决策策略。在本文中，我们评估了缓存决策策略对 ICN/CCN 中视频和音频传输 QoE 的影响。我们使用树形网络的计算机模拟和主观实验的 QoE 来评估应用程序级 QoS。
This paper considers video and audio transmission in ICN (Information-Centric Networking) CCN (Content- Centric Networking), in which each intermediate node can cache content. LCE (Leave Copy Everywhere) has been known as a generic cache decision policy. However, because LCE caches at all the intermediate nodes, the cache of intermediate nodes can be duplicated. Therefore, various cache decision policies that eliminate redundancy have been proposed. In this paper, we evaluate the effect of the cache decision policies on QoE of video and audio transmission in ICN/CCN. We assess application-level QoS using a computer simulation with a tree network and QoE by means of subjective experiment.
