Using sdn technology to enable cost-effective bandwidth-on-demand for cloud services [Invited]

View publication


We describe bandwidth-on-demand in an evolved multilayer, software-defined networking (SDN) based cloud services model. We present motivation for using a multilayer architecture for the wide-area network (WAN). Our laboratory testbed is described, and both the hardware and management architecture are presented. We also show an initial proof-of-concept demonstration of this capability.
