Failure Recovery Using RSWF Algorithm for Advanced Reservation in Optical Grid

Free registration required

Executive Summary

For utilizing distributed resources in optical grid environment advanced reservations play a very crucial role. For applications like the co-allocation of distributed resources and deadline driven applications advance reservations are essential. Also for enhancing capabilities of resource brokers advance reservations play a major role. In this paper, failure recovery has been done depending on schemes such as periodic reconfiguration, and so on using Revised Slide Window First (RSWF) algorithm. Here, RSWF algorithm checks one path at a time for all of the scheduling window slots. If a link or node failure occurs during the reservation then periodic rescheduling can be done in RSWF to perform failure recovery.
