چکیده

Photonic networks using Optical Burst Switching (OBS) emerged as an attractive choice for building the next generation Photonic Internet. In burst switched photonic networks, contentions caused by multiple bursts intending to use the same wavelength of the same link at the same time, remarkably increase burst dropping probability and degrade network throughput. As efficient contention resolution methods, the previously presented deflection routing and priority-based wavelength assignment (PWA) work individually but are not compatible with each other. It is therefore desirable to combine these two methods together to make further performance improvement. In this work, we revamped PWA to support deflection routing and show the improved performance of deflection routing-compatible PWA through simulation results.

On Wavelength Assignment and Deflection Routing for Contention Resolution in Burst Switched Photonic Networks

We present and evaluate a wavelength assignment and deflection routing scheme for contention resolution in burst switched photonic networks in this work. By combing deflection routing and Priority-based Wavelength Assignment (PWA) together and making them compatible with each other, we show the improved performance of deflection routing-compatible PWA through simulation results.

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...

Analysis of Wavelength Conversion and Deflection Routing in Optical Burst Switched Network

In Optical Network contention is one of the big problem. Contention occurs when more than one burst demand for same output wavelength channel in same time. Wavelength conversion and deflection routing are the methods to resolve contention in Optical Network. In this case of wavelength conversion if any contentions occur then one of the burst’s wavelength have to be changed from its current wave...

Iterative Linear Programming Formulation for Routing and Wavelength Assignment in Optical Networks

In this paper, we consider the Routing and Wavelength Assignment (RWA) problem in Wavelength Division Multiplexing (WDM) networks. Firstly, we propose separate linear programming (LP) formulations for the lightpath routing and the wavelength assignment subproblems. Then, an iterative algorithm that integrates both formulations is also proposed for solving the complete RWA problem. The objective...
