About the Talk

Measurement serves as the basis for network management. Figuring out what is going on in the network is often harder than deciding what to do about it. Yet, in today's networks, measurement is an afterthought. Network operators must rely on incomplete and indirect observations of network traffic and performance. Software-defined networking brings new opportunities for rebuilding the network measurement stack to support diverse and dynamic measurement tasks. In this talk, I will first present OpenSketch, a software-defined traffic measurement data plane, which strikes a careful balance between generality (supporting a wide variety of measurement tasks) and efficiency (enabling high link speed and low cost). Next, I will present DREAM, a new measurement framework in the control plane, which dynamically adjusts resource allocation across tasks in reaction to traffic dynamics and task dynamics, while ensuring a user-specified level of accuracy.
