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.

该项目的主要重点是提高多媒体内容交付网络（CDN）的性能，特别是基于软件定义网络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式增长大大增加了用户对流行赛事（如国际体育比赛、现场直播和新闻）的流媒体需求。传统的CDN通常在架构上过于僵化，无法处理用户需求的移动性和快速扩展，这可能导致用户体验质量差，或者需要过度设计基础设施，这导致资本和运营支出增加。具有软件定义的底层基础设施的基于云的弹性CDN可以提供更灵活的架构，以保证这种动态场景中的体验质量（QoE）。我们的目标是开发和验证在多媒体流媒体网络中优化网络服务配置的方法，这些网络在这种软件定义的虚拟化基础设施上运行，特别关注多租户，多服务提供商设置中的保证体验质量。
