Advance reservation for virtual overlay network services

Network advance reservation is an area of growing interest and focus today. However most proposed solutions in this field have only focused on the scheduling of point-to-point client connections. Now as applications and user communities continue to expand, there is a growing need to extend advance reservation support for multipoint services. To address this concern, a heuristic solution is presented for virtual overlay network scheduling. The scheme uses graph-theoretic schemes and is analyzed in detail using network simulation.
