Study of the Defense Simulation Internet (DSI) for the Joint Advanced Distributed Simulation (JADS) Project

摘要

This report investigates the feasibility of the recently upgraded Defense Simulation Internet (DSI) network to support Test and Evaluation (T&E) requirements such as the Joint Advanced Distributed Simulation (JADS) phase two end-to-end (ETE) test. It reviews the features associated with the DSI and discusses how the DSI could be used to support JADS ETE T&E efforts. The DSI provides for bandwidth reservation among its user sites through the use of standards-based Resource ReSerVation Protocol (RSVP). Multicasting is supported so that packets in a distributed simulation are efficiently forwarded. Security is provided by Improved Network Encryption System (INES) boxes built by the Motorola Corporation. Desktop Video Teleconferencing (DVTC) applications can be used among limited number of sites in secure or non-secure mode. A JADS Phase two ETE test configuration for T&E is discussed and a potential configuration for running this test over DSI is presented. Because of the throughput limitations of the INESs (maximum two-way throughput being 1200 Kbits per second), it is suggested that running JADS ETE phase two tests over the DSI is not a viable option at the present time.
