A reliable and realistic approach of advance network reservations with guaranteed completion time for bulk data transfers in grids

Advance Reservation mechanisms in Grid systems should include the network just like any other resource; this is usually not only a technical, but also an administrative challenge. In this paper, we present a QoS mechanism for bulk data transfers which minimizes the necessary support from network service providers. By shifting the complexity of controlling the traffic to end nodes, where we combine admission control with congestion control, we can provide per-flow guarantees while efficiently using the available network capacity.
