Edge computing enables data processing at the edge of the network. It encompasses 3 main concepts: cloudlets, multi-access edge computing (MEC), and fog computing. Cloudlets are resource rich-servers or clusters of servers located in single hop proximity of mobile devices. MEC provides cloud computing capabilities at the edges of networks with a focus on mobile networks. Fog computing is an extension of the cloud from the core to the edge of networks. Two key benefits are expected from edge computing: latency reduction and provisioning of new services and applications. Content Delivery Networks (CDNs) consist of a collection of Web servers distributed over multiple locations to transparently and effectively deliver rcontent to end-users with the required Quality of Experience (QoE). They were traditionally provisioned with static Web technologies but are now more and more often provisioned with modern technologies such as cloud computing. However latency still remains a key roadblock and the introduction of new services and applications (especially the ones which rely on information available solely at the edge) is still an uphill task. This project aims at bringing the benefits of edge computing to the CDN world. We will propose and validate architectures and algorithms which will enable latency reduction and easy introduction of new services and applications in CDNs.****

边缘计算可以在网络边缘进行数据处理。它包含3个主要概念：云计算、多访问边缘计算（MEC）和雾计算。Cloudlet是位于移动的设备的单跳附近的资源丰富的服务器或服务器集群。MEC在网络边缘提供云计算功能，重点关注移动的网络。雾计算是云从网络核心到边缘的延伸。边缘计算预计会带来两个关键好处：减少延迟以及提供新服务和应用程序。内容交付网络（CDN）由分布在多个位置的Web服务器集合组成，以透明有效地向最终用户交付具有所需体验质量（QoE）的内容。 传统上，它们采用静态Web技术，但现在越来越多地采用云计算等现代技术。然而，延迟仍然是一个关键的障碍，引入新的服务和应用程序（特别是那些依赖于仅在边缘可用的信息的服务和应用程序）仍然是一项艰巨的任务。该项目旨在将边缘计算的好处带到CDN世界。我们将提出并验证架构和算法，这些架构和算法将能够减少延迟并在CDN中轻松引入新服务和应用。*
