A critical component of the NIF Integrated Computer Controls System (ICCS) is the local area network (LAN) that enables timely and reliable communication between control applications running on the 600+ computer systems distributed throughout the NIF facility. This project analyzed critical portions of the NIF ICCS network (referred to as "the network" in this report) applying the OPNET Modeler discrete event simulation package to model and simulate network operation and the Network Associates Distributed Sniffer network analyzer to collect actual network performance data in the ICCS Testbed. These tools were selected and procured for use on this project. Simulations and initial network analysis indicate that the network is capable of meeting system requirements. ICCS application software is currently in development, so test software was used to collect performance data. As application software is tested in the Testbed environment, more accurate timing information can be collected which will allow for more accurate large-scale simulations.
