Abstract
A system and method for measurement of the performance of a network by simulation, wherein time divergence is addressed by using discrete event simulation time to control and synchronize time advance or time slow down on virtual machines for large-scale hybrid network emulation, particularly where the loss of fidelity could otherwise be substantial. A dynamic time control and synchronization mechanism is implemented in a hypervisor clock control module on each test bed machine, which enables tight control of virtual machine time using time information from the simulation. A simulator state introspection and control module, running alongside the simulator, enables extraction of time information from the simulation and control of simulation time, which is supplied to the virtual machines. This is accomplished with a small footprint and low overhead.
