A Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks

[Proceeding] Power-Aware Routing and Wavelength Assignment in Optical Networks

We introduce the Power-Aware RWA problem, whose goal is to accommodate lightpaths in wavelength routing networks minimizing the power consumption. Formulation, algorithms, and results are presented, showing that significant power savings are possible. Introduction Wavelength Routing (WR) networks offer the flexibility of designing a “logical topology”, comprising lightpath requests, over a phys...

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...

A simple routing and wavelength assignment algorithm using the blocking island technique for all-optical networks

In this paper we consider the routing and wavelength assignment problem as well as the placement of wavelength converters in a wavelength routed all-optical network. Using a clustering technique called BI (Blocking Island), we propose a simple and intelligent RWA (Routing and Wavelength Assignment) algorithm: BI_RWA and a converter placement algorithm. These algorithms can be used in arbitraril...

Routing and Wavelength Assignment in All-Optical Networks

Abstracf— This paper considers the problem of routing connections in a reeontigurable optical network using wavelength division multiplexing. Each connection between a pair of nodes in the network is assigned a path through the network and a wavelength on that path, such that connections whose paths share a common link in the network are assigned d]fferent wavelengths. We derive an upper bound ...
