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

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.

Physical layer performance of optical packet switches: A practical approach

2011

Simulation results of the OSNR performance of an optical switch/router are presented in this paper. The paper is completed with a cascadability analysis, which takes into account the optical link that joins the nodes, and some results that show the effects of the scheduling algorithm on the optical performance.

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 of Optical Packet Switches Based on Parametric Wavelength Converters

Journal of Optical Communications and Networking, 2010

In an optical packet switch (OPS), input fibers carry multiple wavelengths, each of which carries a packet to one output fiber. As several wavelengths from different inputs could be destined to the same output fiber, one wavelength can be connected and the others remain disconnected, losing the carried packets. Because of the multiple wavelengths available at an output fiber, wavelength conversion in the OPS of the unconnected wavelengths into those available can increase the number of connections. A parametric wavelength converter (PWC) provides multichannel wavelength conversion where wavelengths can be converted to another. A PWC uses a pump wavelength that can be flexibly chosen to define which wavelengths can be converted, defining the so-called wavelength conversion pairs. However, it is unknown which set of pump wavelengths, and therefore the set of connection pairs, should be selected to improve the OPS performance while the number of PWCs in the OPS is reduced. This paper proposes a pump wavelength selection policy for an OPS that uses different pump wavelengths, one for each PWC, within an arbitrarily selected interval. This policy is called a variety-rich (VR) policy. This paper also introduces a non-wavelength-blocking OPS (NWB-OPS) to make full use of PWCs. The switch performance is evaluated through computer simulation. The results show that the proposed policy with different pump wavelengths achieves the highest performance when compared with another of similar complexity. Furthermore, the performance study shows that small sizes of the interval to select a pump wavelength are more beneficial than larger ones. UTC from IEEE Xplore. Restrictions apply.

A Comparison and Performance of Different Optical Switching Architectures

Int'l J. of Communications, Network and System Sciences, 2011

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 the WDM. This study surveys most of the exiting optical packet switching architectures. A simulation-based comparison of input buffered and output buffered architectures is presented. The performance analysis of the selected two architectures is derived using simulation program and compared at different scenarios. We found that the output buffered architectures give better performance than input buffered architectures. The simulation results show that the-broadcast-and-select architecture is attractive in terms that it has lees number of components compared to other switches.
