In this paper, we introduced a new partially preemptive scheduling technique with QoS support. The technique is capable of handling data bursts in parts and may use preemption due to the priorities of data bursts in a multi-service OBS network environment. Simulation studies suggest that more than 50% reduction in dropping probability and approximately 40% improvement in channel utilization is reachable at 0.8 load. The studies also reveal that the new scheduling technique has the ability to predict and control service performance differentiation among defined service classes.

The problem is to find the sequence in which to distribute divisible computing load from a root processor to its children processors which achieves the lowest monetary distribution cost. The convergence performance of a heuristic greedy algorithm is studied. This problem is directly relevant to computer utilities which offer computing and software hosting to organizations for a monetary charge.

The application envisioned is a specialized on-line service that rents time on its machine. The combinatorial optimization problem involved is examined analytically and a heuristic algorithm for its solution is provided. Lessons learned in this work appear in the conclusion.
