Routing algorithms for all-optical networks with power considerations: the unicast case

Routing Algorithms for All-Optical Networks with Power Considerations: The Unicast Case - Computer Communications and Networks, 1999. Proceedings. Eight International Conference on

In this paper, we investigate the problem of routing connections in all-optical networks while allowing for degradation of routed signals by different optical components. To overcome the complexity of the problem, we divide it into two parts. First, we solve the pure RWA problem using fixed routes for every connection. Second, power assignment is accomplished by either using the smallest-gain f...

A Genetic Algorithm for Routing in WDM Optical Networks with Power Considerations Part I: The Unicast Case

Routing and wavelength assignment (RWA) is an important problem that arises in wavelength division multiplexed (WDM) optical networks. Previous studies have solved many variations of this problem under the assumption of perfect conditions regarding the power of a signal. In this paper, we investigate this problem while allowing for degradation of routed signals by components such as taps, multi...

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...

Ant colony optimization for the routing of jobs in optical grid networks

Grid networks provide users with a transparent way to access computational and storage resources. The introduction of (dense) wavelength division multiplexing techniques have made optical networks the technology of choice for data-intensive grid traffic. In a grid network scenario, users are generally more interested in the successful completion of their jobs than in the location where the actu...
