— In this paper, we present the architectural design of optical burst-buffers that can truly emulate input queuing and accommodate asynchronous burst operation. The architectural design uses wavelength converters and fixed feed-forward delay lines that are combined to form either a multiple-input buffer or a shared buffer. Both schemes are modular, allowing the logarithmic expansion of buffer size with the number of switching elements (wavelength converters). Optical burst switching; optical buffers; input queuing; wavelength converters; programmable delay.
