New software controller for S-Series optical circuit switches allows applications to reconfigure and optimize the optical network layer dynamically to deliver maximum performance and efficiency in accessing precious computation and storage resources
Future additions to the controller will add traffic pattern analysis and traffic engineering capabilities to enable hybrid packet-optical network architectures for data centers of all sizes
Santa Barbara, CA, Nov. 19, 2014 — CALIENT Technologies, Inc., the global leader for optical circuit switching technology, today announced a new software controller developed to facilitate dynamic reconfiguration of the optical network layer in cloud data center facilities.
The new Optical Topology Management Controller, built using the OpenDayLight framework, also lays the foundation for hybrid network fabrics in which CALIENT’s S-Series optical circuit switches augment third-party packet-based networks.
In modern cloud data centers, more than 60 percent of traffic is comprised of highly persistent traffic flows that require expensive, high-capacity networks for fast and efficient delivery. These “elephant” flows, typically caused by data replications, storage migrations, and movements of big data sets in Hadoop distributed file systems, can overflow buffers on packet switches, negatively impacting smaller, equally important and latency-sensitive “mouse” flows.
The first release of CALIENT’s Software-Defined Network (SDN)-based Optical Topology Management Controller allows efficient optical topologies to be built on demand, optimizing access to compute and storage nodes to achieve maximum utilization of these critical resources.
With the addition of traffic analysis and traffic engineering capabilities (planned for early 2015), the controller will support the full hybrid packet-optical network, in which the optical layer is reconfigured dynamically to create optical “express” paths that offload highly persistent traffic flows from the L2/3 packet network.
This means that applications and traffic pattern analysis algorithms will be able to drive the optical layer topology to achieve the highest levels of throughput and efficiency, thereby relieving the layer 2/3 network to efficiently deliver the more transient traffic. Pure optical circuit switched networks also offer tremendous cost savings – typically 80 percent less expensive than L2/3 solutions at 100Gbps.
Opens Hybrid Packet–Optical Networks to Wider Range of Data Centers
Until now, this vision of a dynamic optical layer has been available only to the largest data center operators that are able to design their own topology management solutions. The new CALIENT Optical Topology Management Controller makes this architecture available for a wider range of data centers.
“We’ve seen tremendous customer interest in the powerful value proposition of the dynamically reconfigurable optical layer offered by our S-Series optical circuit switches, but the stumbling block has been the lack of a controller to allow applications and traffic patterns to drive and orchestrate the new topologies,” said Daniel Tardent, Vice President of Marketing at CALIENT. “Our new Optical Topology Management Controller is the missing link and we’re now moving ahead on a number of proof of concept deployments with our customers.”
The new CALIENT controller will be used in conjunction with the company’s S-Series family of optical circuit switches. The S320 flagship is a 320-port optical circuit switch used to create an all-optical network fabric with total throughput of more than 32 terabits per second. The switch allows any-to-any, layer one network connections with almost no latency and can be reconfigured on demand under software control. Each switch port is transparent to bit rate and can support data speeds to 100 Gbps and beyond.
The CALIENT Software Defined Optical Topology Manager will be available for proof-of-concept testing and system integration with third party controller solutions starting January 2015. Additional functionality to enable full hybrid packet-optical networks will be announced in first quarter 2015.
