Virtual Overlay Network Scheduling
As applications continue to expand, there is a growing need to provide advance reservation scheduling for higher-end virtual overlay network services. Hence, this paper presents an optimization formulation for this problem and studies several heuristic solutions using network simulation. The need to schedule future user demands, i.e., Advance Reservation (AR), is becoming an integral requirement for a range of applications in grid-computing, e-science, storage backup, community networking, special event broadcasting, etc. Hence, researchers have proposed a range of connection scheduling schemes for various AR service models (fixed start/duration, variable start/duration, etc.) in bandwidth-provisioning and optical wavelength-routing networks.
