Optical Buffering and Switching for Optical Packet Switching
2006 International Conference on Photonics in Switching, 2006We describe the design and initial results of an all-optical buffered 40 Gb/s packet switch. Dynamic packet forwarding is illustrated and specific attention is directed to buffering. We assess the challenges in meeting the requirements for optical buffering devices. Slow light and delay line buffering approaches are described and several recent results

Packet switching or optical switching?
IEEE Internet Computing, 2000One of history's main benefits is that it lets us detect trends that help predict the future. Over the past 30 years since the Internet started (1970-2000), many clear trends have emerged. The article very briefly examines the most critical of these trends, the one that led to the creation of the Internet: the packet switching cost trend.

Demonstration of an optical packet synchronizer for an optical packet switch
Optical Fiber Communication Conference and Exhibit, 2002We have demonstrated a compact optical packet synchronizer. With a tunable DBR LD and SOA gates, the synchronization is successfully achieved with simple electric circuits by controlling the switching timing. Because OFCs are used, the OPSy is compact and the delay time can be controlled precisely.

Optical Packet Switching and Optical Burst Switching
2020Optical transmission has long been the established choice for nonwireless data transmission spanning distances longer than a few tens of meters, due to its high bandwidth and electromagnetic noise immunity. Most current high-bandwidth networks are essentially a group of fiber-optic links connected by nodes whose function is to forward incoming data to ...

Impacts of packet filling in an optical packet switching architecture
Advanced Industrial Conference on Telecommunications/Service Assurance with Partial and Intermittent Resources Conference/E-Learning on Telecommunications Workshop (AICT/SAPIR/ELETE'05), 2005Increase in network traffic and emergence of a variety of applications requiring different QoS necessitate scalable and efficient resource utilization. An appealing solution for backbone networks is the optical packet switching architecture. However technological constraints prevent the deployment of such all-optical solutions.

Packet scheduling in a low latency optical packet switch
2010 International Conference on High Performance Switching and Routing, 2010In this paper, we study packet scheduling in the OpCut switch, a recently proposed optical switching architecture that can be adopted for high-performance parallel computers. The key feature of the OpCut switch is that it allows packets to cut-through the switch whenever possible, such that packets experience minimum delay.

This chapter provides an outline of the main concepts and issues related to optical packet switching (OPS). The basic network functions required by this paradigm are discussed and references to past and current research on the topic are provided. Optical packet switching is a transport technique that assumes information to be organized in packets ...

On Traffic Allocations in Optical Packet Switches
IEEE Journal on Selected Areas in Communications, 2007In this paper, we study the impacts of traffic allocations on the performance of optical packet switches (OPS). In particular, two different cases are investigated where traffic loads are distributed over different (i) time slots (time dimension); and (ii) output ports (space dimension), respectively.

Approaches to optical Internet packet switching
IEEE Communications Magazine, 2000Wavelength-division multiplexing is currently being deployed in telecommunications networks in order to satisfy the increased demand for capacity brought about by the explosion in Internet use. The most widely accepted network evolution prediction is via an extension of these initial predominantly point-to-point deployments, with limited system ...

Clos lives on in optical packet switching
IEEE Communications Magazine, 2004While the technological evolution since C. Clos's seminal article (see Bell Sys. Tech. J., vol.32, p.406-24, 1953) on multistage switch architectures has been huge, his work and ideas still live on. We discuss node architectures for optical packet switching and show how the multistage approach proposed by Clos can be adopted to solve scalability issues
