项目摘要

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.****

边缘计算在网络边缘启用数据处理。它包括3个主要概念：Cloudlets，Multi-Access Edge Computing（MEC）和雾计算。 Cloudlet是资源丰富的服务器或位于移动设备的单个HOP接近的服务器群。 MEC在网络边缘提供云计算功能，重点是移动网络。雾计算是从核心到网络边缘的云扩展。 Edge计算预计将有两个关键的好处：减少延迟和新服务和应用程序的配置。内容输送网络（CDN）由分布在多个位置上的Web服务器的集合组成，以透明有效地将RCONTENT交付给最终用户所需的经验质量（QOE）。传统上，它们是用静态网络技术提供的，但现在越来越多地使用诸如云计算之类的现代技术来提供。但是，潜伏期仍然是一个关键的障碍，并且引入新服务和应用程序（尤其是依靠仅在边缘可用的信息的服务）仍然是一项艰巨的任务。该项目旨在将边缘计算的好处带入CDN世界。我们将提出和验证体系结构和算法，以减少延迟，并轻松引入CDNS中的新服务和应用。****
