A simulation environment for EIA-709.1/IP routers

Abstract

EIA-709.1/IP routers enable the extension of Lon-Works networks over the Internet, using it as just another transmission channel. To investigate the influence of delay jitter and loss rates, this paper presents a simulation framework for both Lon- Works nodes and routers. The Network Simulator ns-2 from UC Berkeley is extended by fieldbus nodes and EIA-709.1/IP routers. The simulation executes EIA-709.1 transport layer transactions using a sender/receiver model. Different router implementations can be analyzed using a generic scenario with sending nodes connected to local and remote receiving nodes.
