Comparative Analysis of Routing and Wavelength Assignment Algorithms used in WDM Optical Networks
This study aims at highlighting the Routing and Wavelength Assignment (RWA) problems in WDM Optical networks and describes the Routing Algorithms and their performance comparison. Since routing decisions play an important role in evaluating the blocking performance of a network it is critical to choose a wavelength assignment scheme that should take into account its compatibility with the chose...
متن کاملWavelength Assignment and Routing in WDM networks
With wavelength division multiplexing (WDM) several optical signals can be transferred in a single optical ber [6][7]. This technology allows more e cient use of the huge capacity of an optical ber but also poses new network design and management problems, especially when wavelength conversion is not possible in the nodes. In this paper we consider the routing and wavelength assignment problem ...
متن کاملMultihop Routing and Wavelength Assignment Algorithm for Optical WDM Networks
We propose a new routing and wavelength assignment scheme that improves the blocking probability of WDM networks and offers a very good utilizat ion of the networks resources. This heuristic results in high quality of service, prioritization of the LAN networks and lower installat ion costs compared with the traditional RWA algorithms applied in WDM networks. It is based on the distributed Dijk...
متن کاملRouting, wavelength assignment, and spectrum allocation algorithms in transparent flexible optical WDM networks
Current fixed grid wavelength routed networks are limited in terms of spectral efficiency due to the rigid nature of wavelength assignment. We propose the Flexible Optical WDM (FWDM) network architecture for flexible grid optical networks in which the constraint on fixed spectrum allocation to channels is removed and network resources can be dynamically provisioned with an automated control pla...
متن کاملDistributed Routing and Wavelength Assignment Algorithms for Dynamic WDM All-optical Networks
The problem of establishing lightpath between a given source-destination pair through routing and assigning wavelength to the route is known as routing and wavelength assignment (RWA) problem. In this paper, we have proposed a set of distributed algorithms for dynamic RWA problem in WDM All-optical networks. We have made a comparative study of different distributed algorithms in terms of blocki...
