On RWA Algorithms for Scheduled Lightpath Demands in Wavelength Division Multiplexing Networks

We have proposed and evaluated a novel heuristic algorithm of routing and wavelength assignment (RWA) for scheduled lightpath demands (SLD). Our algorithm works on directed and undirected optical networks, and is shown here to have a performance gain in terms of the number of wavelengths upto 65.8 % compared with the most recently introduced method, TDP_RWA. Also, we show the execution time of ...

RWA on Scheduled Lightpath Demands in WDM Optical Transport Networks with Time Disjoint Paths

In optical networks, traffic demands often demonstrate periodic nature for which time-overlapping property can be utilized in routing and wavelength assignment (RWA). A RWA problem for scheduled lightpath demands (SLDs) has been solved by combinatorial optimal solution (COS) and graph coloring, or heuristic sequential RWA (sRWA). Such methods are very complex and incurs large computational over...

Routing and wavelength assignment of scheduled lightpath demands

In this paper, we present algorithms that compute the routing and wavelength assignment (RWA) for scheduled lightpath demands in a wavelength-switching mesh network without wavelength conversion functionality. Scheduled lightpath demands are connection demands for which the setup and teardown times are known in advance. We formulate separately the routing problem and the wavelength assignment p...

Routing and Wavelength Assignment for Scheduled and Random Lightpath Demands: Bifurcated Routing versus Non-Bifurcated Routing

We consider the routing and the wavelength assignment (RWA) of scheduled and random lightpath demands in a wavelength switching mesh network without wavelength conversion functionality. Scheduled lightpath demands (SLDs) are connection demands for which the set-up and tear-down times are known in advance as opposed to random lightpath demands (RLDs) which are dynamically established and release...

Strategies for the Routing and Wavelength Assignment of Scheduled and Random Lightpath Demands

We propose three routing strategies for the routing and wavelength assignment (RWA) of scheduled and random lightpath demands in a wavelength-switching mesh network without wavelength conversion functionality. Scheduled lightpath demands (SLDs) are connection demands for which the set-up and tear-down times are known in advance as opposed to random lightpath demands (RLDs) which are dynamically...
