CALIENT Technologies will be releasing an application programming interface (API) for OpenFlow on its S320 optical circuit switch. This will allow the S320 to optimize high-capacity data flows at the optical layer and to function as part of an integrated packet-circuit switched software-defined network (SDN).
Calient’s 320-port (full duplex) S320 is a MEMS-based optical switch that connects top-of-rack switches in a data center. The OpenFlow API runs on the S320’s MEMS Switching Module (MSM), a high-availability switching and control subsystem with redundant control processors and a Linux-based operating system.
Calient said an OpenFlow controller can reconfigure S320 connections based on time of day, real-time application flows or predictive algorithms.
