EONA

There is a growing recognition among researchers, industry practitioners, and service providers of the need to optimize user-perceived application experience. Network infrastructure owners (i.e., ISPs) have traditionally been left out of this equation, leading to repeated tussles between content providers and ISPs. In parallel, application providers have to deploy complex workarounds that reverse engineer the network's impact on application-level metrics. In this work, we make the case for EONA, a new network paradigm where application providers and network providers can collaborate meaningfully to improve application experience. We observe a confluence of technology trends that are enablers for EONA: the ability to collect large volumes of client-side application measurements, the emergence of novel "big data" platforms for real-time analytics, and new control plane capabilities for ISPs (e.g., SDN, IXPs, NFV). We highlight the challenges and opportunities in designing suitable EONA interfaces between infrastructure and application providers and EONA-enhanced control loops that leverage these interfaces to optimize user experience.
