Session Abstract

This session will demonstrate an innovative, vendor agnostic implementation of SDN controllers within and between data centers connected by a packet optical metropolitan area networks (MAN). This approach can serve as a model for other organizations in the research and education community interested in multi-tenant cloud computing environments. We have created open source software to perform monitoring, control, and dynamic provisioning on wavelength division multiplexing (WDM) optical transport platforms. Our approach is based on industry standard implementations of the OpenFlow specification. An API is used to collect network monitoring information from each WDM wavelength channel, including traffic profiles, bandwidth utilization, and network topology information. The network is subdivided into several virtual slices, each of which can be assigned to a different cloud tenant. Further, each cloud tenant can use a different type of network controller to manage resources on their slice of the network. A hybrid cloud architecture such as those commonly used by the Internet2 community could use this approach to dynamically assign network resources to multiple clients without over-provisioning the optical network, resulting in lower operating costs and more efficient utilization of network bandwidth. Using data collected by our industry partners, we show that dynamic bandwidth on the MAN is able to address performance bottlenecks for use cases such as synchronous storage in a hybrid cloud. Our approach is able to respond to short duration traffic bursts, which cannot be efficiently handled using conventional over-provisioned network circuits. We can also achieve significantly faster automated network resource provisioning using this innovative solution.
