Multihop 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 کاملA Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks
Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of regeneration capabilities, the physical layer i...
متن کاملDistributed Wavelength Assignment Algorithm for Optical Bursts in WDM Networks
We present a distributed wavelength assignment algorithm named Priority-based Wavelength Assignment (PWA) for the contention resolution problem in buffer-less burst optical networks without wavelength conversion capability. Simulation results show that the PWA can effectively reduce the blocking probability and increase the performance of burst optical networks compared to previous algorithms s...
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 کاملMulti-Path Routing and Wavelength Assignment Algorithm (RWA) for WDM Based Optical Networks
In optical WDM networks, transmission of information along optical lines is advantageous since it has high transmission capacity, scalability, feasibility and also high reliability. But large amount of information is being carried; any problem during transmission can lead to severe damage to the data being carried. Hence it is essential to consider the routing as well as the wavelength assignme...
