Abstract

The use of a dynamic reconfigurable optical network is an important requirement for the new advanced resource-intensive, highly distributed Grid applications that begin to emerge on the e-Science field. In this paper, we propose an ACO-based algorithm that is capable of the co-scheduling of both computational and optical network resources. We assess the performance of the proposed algorithm by comparison with traditional publish-and-subscribe grid systems that make use of topological routing of the lightpaths. The proposed algorithm can be used as a viable alternative for grid scheduling in Lambda Grids.
