Frankfurt, Germany – Infinera and Brocade, in collaboration with the U.S. Department of Energy’s Energy Sciences Network (ESnet), announced today the successful demonstration of multi-layer networking using Software-Defined Networking (SDN) technologies. The demonstration shows how SDN can be used to automatically provision services and optimize network resources, such as dynamically increasing or rerouting data center to data center interconnect bandwidth services, across a multi-layer network as traffic demands change.

The first phase of this new demonstration leveraged ESnet’s On-Demand Secure Circuits and Advance Reservation System (OSCARS) in conjunction with an open source controller to provision services over network elements at both the packet and transport layers via the OpenFlow™ protocol. A 100 GbE service was provisioned across the multi-layer network comprising of Brocade® MLXe Core Routers and additional OpenFlow-enabled Layer 2 switches connected over a virtualized transport network consisting of three Infinera DTN-X platforms, each running Infinera’s Open Transport Switch software module. Multi-layer provisioning using SDN enables services and bandwidth to be dynamically provisioned via a single screen across the router layer and transport layer to speed service delivery and save operational costs.

The second phase of the demonstration focused on multi-layer network optimization and demonstrated how proactive detection of increasing bandwidth of packet flows could trigger OSCARS to dynamically re-route the large flow to bypass an intermediate packet switch/router. This approach leverages SDN to maximize the use of the intelligent DTN-X transport layer with integrated switching to minimize transit traffic carried at the router layer. Automated multi-layer optimization analyzes network topology and traffic flows to route traffic at the most cost-effective and energy-efficient layer of the network to save both capital and operational costs.
