SDN Architecture on Fog Devices for Realtime Traffic Management: A Case Study

Abstract

Software Defined Network has become one of the most important technology to manage the large scale networks.The separation of the control plane from the data plane in networking devices is the main idea of SDN. Currently, Open Flow is the popular SDN standard, which has a set of functionalities.In the emerging cloud scenario smart devices plays an important role. But they are facing latency and intermittent connectivity. For this fog devices are placing in-between cloud and smart devices.Fog computing is currently applying on connected vehicles, sensor network etc. This article looks into the vehicular network area as a case study where SDN architecture can apply on fog devices for enhancement of the performance and betterment of traffic management and QoS on distribution of real time data.
