SRL Researchers Successfully Routed Network Traffic Through Optical Switches with Sub-Millisecond Configuration Time Via Fujitsu Flashwave 9500

The experiments were part of the National Science Foundation (NSF) funded effort in prototyping the DWDM multi-mode switching router, an important step towards next generation optical networks. Internal network traffic from Fujitsu Flashwave 9500 packet optical networking platform has been successfully routed through low-power optical switches with sub-millisecond configuration time.

SRL researchers are developing devices that that could automatically control the optical switches, thus realizing real-time configuration of Flashwave 9500. Two configurations were tested with the sub-millisecond optical switch. The first configuration routed the traffic from the output port of the switching fabric (SF) to the input port of the optical multiplexing device. The second configuration routed the traffic from the output port of the multiplexing device to the input of the wavelength selectable switch (WSS). Results showed that the configurations were compatible with network traffic running through Flashwave 9500. Latency is one of the core metrics when evaluating the performance. Latency measurements will be conducted using 3Com switches as well as Xilinx FPGA board as auxiliary devices.
