Abstract

Bandwidth-on-Demand (BoD) as a network service (BoD-as-a-Service) is integrated into applications that end-users can flexibly purchase when and for however long they need it. A centralized Software Defined Networking (SDN) controller and distributed SDN controller agents that may be seen in a Service Provider, Enterprise or distributed computing environment with remote and mobile end-users is provided. The end-user initiates the BoD request using an application via desktop, cloud, smartphone or tablet. The BoD Service Provider, Enterprise, has a controller-based centralized view of the complete SDN service topology. On receiving the request, the BoD provider dynamically computes the optimal end-to-end path through the SDN topology that best suits the end-user requested traffic types and service level requirements. It then translates that optimal path into flow computations that are dynamically pushed down to the controller agents to provision the BoD network path in real-time. An on-demand and real-time bandwidth service for consumers are herein provided where it was previously too costly or too time consuming to set up.
