A Virtual Time System for Virtualization-Based Network Emulations and Simulations

Simulation and emulation are commonly used to study the behavior of communication networks, owing to the cost and complexity of exploring new ideas on actual networks. Emulations executing real code have high functional fidelity, but may not have high temporal fidelity because virtual machines usually use their host's clock. To enhance temporal fidelity, the authors designed a virtual time system for virtualization-based network emulations and simulations, such that virtual machines perceive time as if they were running concurrently in physical world.
