Optimal Scheduling of File Transfers with Divisible Sizes on Multiple Disjoint

In this paper I investigate several offline and online data transfer scheduling problems and propose efficient algo-rithms and techniques for addressing them. In the offline case, I present a novel, heuristic, algorithm for scheduling files with divisible sizes on multiple disjoint paths, in order to maximize the total profit (the problem is equivalent to the multiple knapsack problem with divisible item sizes). I then consider a cost optimization problem for transferring a se-quence of identical files, subject to time constraints imposed by the data transfer providers. For the online case I propose an algorithmic framework based on the block partitioning method, which can speed up the process of resource alloca-tion and reservation. 1
