Algorithm for wavelength assignment in optical networks

A 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...

Distributed 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...

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...

CoS-oriented Wavelength Assignment Algorithm in Burst Switching Optical Networks

We present a CoS-oriented wavelength assignment algorithm for burst switching optical networks with multiple service classes. Simulation results show that CoS is realized in terms of burst blocking probability and throughput.
