Abstract
Systems and methods are disclosed to schedule virtual machine (VM) migrations by analyzing VM migration behavior; building a simulation tool to predict time for multiple migrations under different links conditions and VM characteristics; determining a predetermined bandwidth sharing policy for each network link; applying a bin-packing technique to organize bandwidth resources from all network links, and allocating the links to different migration tasks.
