Optical Packet Switching: Approach to Performance Modeling and Simulation
As (1) above, but E-mail: M.Marciniak@itl.waw.pl ABSTRACT The paper describes research progress in technologies and architectures that give hope to deliver truly transparent switching of optical packets. The importance of all-optical packet switching/routing for convergent next generation transport network and in particularly, for QoS packet transfer in core of future generation wireless networks is pointed out. Generic photonic packet switch/router architecture and its QoS possibilities as well as approach to optical packet format are studied in detail. Conditions for accurate performance modeling and computer simulation for any optical packet switch architecture are discussed. Optical components functionality modeling and optical switch/router simulation algorithms are presented as well.

Electronic Interfaces for Optical Packet Switching and Routing
Revista Científica
Resumo -Apresentam-se aqui novos circuitos para identificação, roteamento e resolução de contenda entre pacotes ópticos com cabeçalho em freqüência, integralmente desenvolvidos em nossos laboratórios. Os tempos de processamento dos circuitos eletrônicos são muito rápidos: os circuitos de reconhecimento de cabeçalho (HRC) e de decisão lógica (LDC) respondem em 40 ns. Ambos circuitos foram construídos usando tecnologia fast TTL. O chaveamento, roteamento e a solução de contenda são realizados pacote-a-pacote sem que haja degradação ou perda de pacotes ópticos. Este sistema é aplicável em chaveamento óptico de pacotes em futuras redes fotonicas transparentes.
Review of Optical World Technologies and Switching Network Devices
Optics is the science of light and has a very long history. In the modern world of telecommunication and information and communication technologies (ICT), the term “photonics” is sometimes used for the application of optical technology, such as lasers and optical fiber, in electronics.In the past, high costs have prevented optical components from finding their way into computers. But as optical technology matures, prices drop and the limits of miniaturization appear to have been reached, the computer industry is re-evaluating the situation and incorporating optical alternatives into computer systems. The use of all types of optical equipment in communication networks and computers, because they consume less power, is seen as a major saving on operational costs for service providers, while at the same time helping to reduce the carbon footprint of telecommunication. The gradual incorporation of optical technology into the world of traditional electronics is paving the way for the era of the optical world
Design and Analysis of Optical Packet Switch Routers
Advances in Wireless Technologies and Telecommunication
Optical packet switching is connectionless networking solution through which we can get high speed data transfer and optimum bandwidth utilization using wavelength division multiplexing technique. For realizing optical packet switching the numbers of optical packet switch architectures are available in market. In this chapter the authors discuss the overall development of optical packet switching; some recently published optical packet switch architectures are discussed in the chapter and a comparison is performed between the switches through loss, cost and buffer analysis.
Performance Analysis of Different Optical Switching Architectures
Journal of Computer Science, 2011
Problem statement: Optical Packet Switching (OPS) and transmission networks based on Wavelength Division Multiplexing (WDM) have been increasingly deployed in the Internet infrastructure over the last decade in order to meet the huge increasing demand for bandwidth. Several different technologies have been developed for optical packet switching such as space switches, broadcast-and-select, input buffered switches and output buffered switches. These architectures vary based on several parameters such as the way of optical buffering, the placement of optical buffers, the way of solving the external blocking inherited from switching technologies in general and the components used to implement WDM. Approach: This study surveys most of the exiting optical packet switching architectures. A simulation-based comparison of input buffered and output buffered architectures were presented. Results: The performance analysis of the selected two architectures derived using simulation program and compared at different scenarios. We found that the output buffered architectures give better performance than input buffered architectures. Conclusion: The simulation results shows that the-broadcast-and-select architecture is attractive in terms that it has lees number of components compared to other switches.
