This paper presents an overview of the project CASPER,1 a 4-year Marie Curie Research and Innovation Staff Exchange (RISE) project running between 2016 and 2020, describing its objectives, approach, architecture, tools and key achievements. CASPER combines academic and industrial forces towards leveraging the expected benefits of Quality of Experience (QoE) exploitation in future networks. In order to achieve that, a QoE orchestrator has been proposed which implements the basic functionalities of QoE monitoring, estimation and management. With means of simulation and testbed emulation, CASPER has managed to develop a proprietary SDN Controller, which implements QoE-based traffic rerouting for the challenging scenario of HTTP adaptive video streaming, leading to more stable and higher QoE scores compared to a state-of-the-art SDN Controller implementation.

CASPER以用户为中心的方法,用于在移动网络中提供高级服务

本文概述了CASPER项目1这项为期4年的玛丽居里研究与创新人员交流(RISE)项目在2016年至2020年之间运行,描述了其目标,方法,架构,工具和关键成就。CASPER结合了学术和产业力量,以在未来的网络中利用体验质量(QoE)开发的预期收益。为了实现这一目标,已经提出了QoE编排器,该编排器实现了QoE监视,估计和管理的基本功能。通过仿真和测试平台仿真,CASPER成功开发了专有的SDN控制器,该控制器实现了基于QoE的流量重路由,以应对HTTP自适应视频流的挑战性场景,与状况相比,QoE得分更加稳定和更高。最新的SDN控制器实现。
