ONOS Build 2016

This talk will introduce the implementation of DPI into ONOS.To cope with the performance and scalability problem of current OpenFlow protocols flow statistics collection mechanism due to the per-flow based polling, AFM & SDPI provide algorithms, protocols, and facilities to collect flow statistics efficiently to reduce the overhead of controllers.  AFM reduces overhead by adjusting flow collection rate adaptive to the characteristics of flow size.  SDPI performs deep packet inspection to some specific flows (e.g., flows for premium service customers) for accurate application analysis or anomaly detection purposes.  In this presentation, Taesang Choi will review the state-of-the-art of traffic flow monitoring for SDN, discuss the associated challenges, introduce the ONOS OPEN-TAM subproject that implements AFM & SDPI functionality, and describe experiences on the deployed use cases and future work.
The audience is anyone interested in traffic flow monitoring and analysis development for SDN and NFV networks. Especially, SDN network equipment, SDN/NFV NMS/OSS, SDN/NFV orchestrator, and network anomaly detection & analysis solution vendors are the favorable audience.  Attendees can expect information on the SDN/NFV traffic monitoring technology state-of-the-art, main outstanding challenges, and the solution with use case deployment experiences.
