TeleScope: Flow-Level Video Telemetry Using SDN

摘要: Internet Service Providers (ISPs) are struggling to cope with the growing volume of streaming video traffic in their network, and problem will only exacerbate as Virtual Reality applications proliferate. To classify manage bandwidth for streams, current practise is either sample offline analysis or deploy middle-boxes in-line packet inspection – such solutions inaccurate and/or expensive. In this paper we present Telescope, a low-cost system comprising commodity SDN switch server, identify profile individual flows at line-rate. We develop an architecture that dynamically manages flow-table entries minimal mirroring packets, prototype our solution using Noviflow OpenFlow switch, coupled Bro engine application on Ryu controller, lastly, validate real streams campus WiFi test its scaling thousands hardware-based generator. believe offers great potential real-time classification operational network very low cost.
