Model-driven network emulation with virtual time machine
Jason Liu, Raju Rangaswami, Ming Xin Zhao · 2010
We present our initial work on VENICE, a project that aims at developing a high-fidelity, high-performance, and highly-controllable experimental platform on commodity computing infrastructure to facilitate innovation in existing and futuristic network systems. VENICE employs a novel model-driven network emulation approach that combines simulation of large-scale network models and virtualmachine-based emulation of real distributed applications. To accurately emulate the target system and meet the computation and communication requirements of its individual elements, VENICE adopts a holistic machine and network virtualization technique, called virtual time machine, in which the time advancement of simulated and emulated components are regulated in complete transparency to the
