SDN based service provisioning management in smart buildings

Foundation of every smart building is local area network connecting devices and systems for enabling provisioning of in-building and Internet based services. In the Internet of Things era, in-building local area networks are becoming more complex with support for plethora of access technologies, support for edge processing, interconnecting IoT gateways and supporting different mission critical services depending on low latency and high reliability all while supporting internal company business processes and high QoS for Internet based services like web browsing, content delivery and video streaming. It is evident that smart building local area networks require proper solution for context and service aware resource management. In this paper we introduce SDN-based approach and controller for context aware service provisioning management. We focus on mission critical services of building management system, VoIP for inbuilding voice communication and content delivery. We will show that our SDN controller enables context and service aware utilization of edge processing and storage capacities of the in-building IP infrastructure to ensure required QoS levels for these different classes of in-building and Internet based services.
