An Optical Packet Switch based on Parametric Wavelength Converters
In an OPS, an optical fiber carries several wavelengths to transmit packets. An input fiber may carry as many packets as wavelengths that could be destined to one or several output fibers. The output contention occurs when multiple packets from different input fibers are destined to a single output fiber using the same wavelength at the same time. Only one packet is forwarded to the output fibe...
متن کاملA hybrid pump wavelength assignment scheme for optical packet switch with parametric wavelength converters
This paper proposes a pump wavelength assignment scheme for an optical packet switch with parametric wavelength converters (PWCs) to reduce the number of different colored light sources while a predefined packet loss rate is satisfied. PWCs are separated into two sets. First set, each PWC has a different pump wavelength from each other. Second set, all PWCs have the same pump wavelength placed ...
متن کاملPractical solutions for optical packet switches with shared wavelength converters: performance and complexity evaluations
Multi-stage optical packet switching fabric based on the broadcast-and-select principle is considered to implement the shared-per-node wavelength conversion scheme. This approach fairly allows to combine contention resolution in the wavelength and space domains. A scheduling algorithm is proposed to control optical packet forwarding in synchronous context. The results aim at showing how the sha...
متن کاملWDM Optical Packet Switches with Bufferless and Partially Shared Buffering Wavelength Converters
Abstract-In this paper we introduce two architectures for optical packet switches. One is a bufferless switch employing shared Tunable Wavelength Converters (TWCs), and the other is a packet switch with Partially Shared Buffering (PSB). They were proposed for solving problems of contention resolution. The bufferless optical packet switch employing shared TWCs allows a saving in terms of employe...
متن کاملDemonstration of bufferless optical packet switch with recursive stages of parametric wavelength converter
We demonstrate in an experiment an optical packet switching (OPS) using recursive parametric wavelength converters (PWCs) which uses the combination of two or more PWCs for wavelength conversions. The PWCs, which are based on four-wave mixing in highly nonlinear fibers, are possible for multiple wavelength conversion, allowing a shareper-node switching scheme, and thus significantly reducing th...
