Performance Evaluation of Fixed Grid and Flex Grid in Dense Wavelength Division Multiplexing

Abstract

Since the Internet services (video conferencing, cloud services and video streaming) and consequently traffic demands are increasing continually, leading to huge traffic growth in the core optical network. There is a need for network operators to increase their optical network capacity to follow this traffic growth

The aim of this thesis to Perform Evaluation of Fixed Grid and Flex Grid in Dense Wavelength Division Multiplexing and analyze the effect of using Flex Grid on the proposed network, different levels of Bandwidth were taken to observe the utilization .It has been observed that at flex can save BW by reducing the space between channels
