Dynamic Establishment of All-Optical Connections in Wavelength-Routed Optical Networks Using Genetic Algorithms

In this paper we propose the use of genetic algorithms (GA) for solving the problem of dynamic establishment of all-optical connections in wavelengthrouted optical networks. All-optical connections can be required to be either fault tolerant or not. We first consider the case where no failure restoration capability is demanded to the optical layer. In this case, an all-optical connection consis...

Chromatic Dispersion Compensation using Optical All Pass Filters

The purpose of this paper is to experimentally study Optical All Pass Filters (OAPF) and optimize the value of distance of origin from poles (r). Using the value of transfer function of optical all pass filter which is of 2 order we found the factor of numerator and denominator. In this work, we took the value of ̳r‘ as 0.660 and the angular position (w0) as 0.390. The power taken as 18dBm. Whe...

Wavelength Assignment Optimization for All-Optical Networks Using Evolutionary Computation

This paper presents a novel wavelength assignment algorithm for alloptical networks. The main idea is to determine the wavelength assignment order for a first fit algorithm taking into account the physical layer effects of four wave mixing and residual dispersion by using a training algorithm inspired in evolutionary computation concepts. The intelligent algorithm presents some concepts recentl...
