The main focus of this project is on improving the performance of multimedia content delivery networks (CDN), in particular based on novel functionalities that software-defined networking and network function virtualization brings to such networks. The explosion of broadband access around the world has significantly scaled up user demand for the streaming of popular events such as international sport matches, live events and news. Traditional CDNs are often too architecturally rigid to deal with mobility and quick scaling of user demands, which may result in either poor quality of experience for the users, or require over-engineering of infrastructure which results in an increase in capital and operational expenditure. Elastic Cloud-based CDNs with a software-defined underlying infrastructure could provide a much more flexible architecture to guarantee Quality of Experience (QoE) in such dynamic scenarios. Our objective is to develop and validate methods for optimal network service provisioning in multimedia streaming networks that are operating on top of such software-defined virtualized infrastructures, with particular focus on guaranteed Quality of Experience in a multi-tenant, multi-service provider setting.

本项目的主要重点是提高多媒体内容分发网络(CDN)的性能，特别是基于软件定义的联网和网络功能虚拟化为此类网络带来的新功能。世界各地宽带接入的爆炸性增长显著增加了用户对国际体育比赛、现场活动和新闻等热门活动的流媒体需求。传统的CDN往往在架构上过于僵化，无法处理移动性和用户需求的快速扩展，这可能会导致用户的体验质量较差，或者需要过度设计基础设施，从而导致资本和运营支出的增加。基于弹性云的CDN具有软件定义的底层基础设施，可以提供更灵活的架构，以保证此类动态场景下的体验质量(QOE)。我们的目标是开发和验证在这种软件定义的虚拟基础设施之上运行的多媒体流传输网络中的最佳网络服务提供方法，特别关注在多租户、多服务提供商设置中保证体验质量。
