In this paper, we propose new optical switching architectures supporting asynchronous and variable-length packets. Output line contention is resolved by optical delay line buffers. By introducing a WDM technology, parallel buffer can be equipped with multiple wavelengths on the optical delay line buffer. Differently from existing approaches, a main feature of our proposed architecture is that b...

Current optical switching technologies allow us to rapidly deliver the enormous bandwidth of wavelength division multiplexed (WDM) networks. Broad acceptance of fiber optic and photonic technology in transmission systems has led to potential opportunities for using all-optical switching to utilise high bandwidth of the fiber and to cater the ever increasing demand of higher bandwidths. The majo...

We study photonic packet switches to support asynchronously arriving variable-length packets. A scheduler for contention resolution is operated in electrical domain even when data street of the buffer is provided in optical domain. In this scheme, the scheduler may be a bottleneck. To compensate the gap of high-speed optical transmission and slow-speed electronic processing, we propose a multi-...

Optical packet switching can seamlessly integrate data networking and optical networking [1]. Recent advances in optical technology make it possible to create systems with the capability to do switching in multiple domains (time, space and wavelength). Time-slot-interchange (TSI) is a form of network switching in time domain. Previous experimental TSI systems involve semiconductor laser amplifi...

Over the past few years, the Internet traffic has grown rapidly and the optical transport bandwidth has been continuously increasing. These changes are stimulating the evolution of data networks. In such a dynamic environment, a network architecture that accommodates multiple data formats, supports high throughput, and is capable of flexible bandwidth provisioning is the key to the design and d...
