Applying parallel and distributed simulation to remote network emulation

Many of today´s military services and applications run on geographically distributed sites and need to be tested and evaluated under realistic scenarios with many unpredictable factors. A remote network emulation framework called ROSENET is proposed that can meet this requirement by using a remote parallel simulation server to model the wide area network and a local network emulator to provide timely QoS predictions for real world applications. This paper discusses problems faced in applying parallel and distributed simulation technique for the remote network emulation. The experimental results show that timeliness and remote accessibility are main concerns in applying parallel simulation to remote network emulation.
