ABSTRACT
Content Delivery Networks (CDNs) differ from other caching systems in terms of both workload characteristics and performance metrics. However, there has been little prior work on large-scale measurement and characterization of content requests and caching performance in CDNs. For workload characteristics, CDNs deal with extremely large content volume, high content diversity, and strong temporal dynamics. For performance metrics, other than hit ratio, CDNs also need to minimize the disk operations and the volume of traffic from origin servers. In this paper, we conduct a large-scale measurement study to characterize the content request patterns using real-world data from a commercial CDN provider.

Hybrid storage-based caching strategy for content delivery network services
This study proposes a novel caching scheme for content delivery network services. In general, video content users often watch the first part of video clips and then switch to other content. Therefore, a caching scheme is proposed, in which the first ...
Caching Policies for D2D-Assisted Content Delivery Systems
WirelessEdge '18: Proceedings of the 2018 on Technologies for the Wireless Edge WorkshopWe consider a content delivery system consisting of a central server and multiple end-users. The central server stores the entire catalog of contents on offer and can deliver the requested content to the end-users. In addition, the end-users are ...
