This paper reports on the Scaleable High Performance LAN SHPL, the networking infrastructure for the Navys FY-96 Joint Power ProjectionReal Time Support JPPRTS Core Technology Program aboard USS Theodore Roosevelt CVN-71. The program demonstrates advanced concepts in strike planning, visualization, and execution using the latest technology in high speed computing, 3-D graphics, and networking. The Joint Power Projection application that SHPL supports involves the coordination of Air Tasking Orders ATOs among CTAPS, TSCM and APPEX, the display via APPEX of TSCM auto-route missions, the review of missions by Strike Lead, the passing of missions to TAMPS for detailed aircraft planning, the review of the mission concept by CAG, and the overall mission preview by TSCM and APPEX. The SHPL, or networking element of the JPPRTS Core Technology Program, is a totally fiber optic shipboard network that is based on asynchronous transfer mode ATM and switched Ethernet technology. The SHPL network demonstrates both permanent virtual circuits PVCs and switched virtual circuits SVCs, handles IP frames via both classical IP RFC 1577 and FORE IP, and demonstrates the LAN emulation functionality of the ATM Forums LANE 1.0 standard. In addition to handling computer data such as file transfer, imagery and email, the SHPL network handles voice and video in the form of interactive video teleconferencing VTC, shared X-windows applications via SharedX, interactive electronic whiteboarding, and NTSC video via ATM. SHPL also demonstrates the network management of a hybrid ATM and Switched Ethernet network, and cable plant configuration management. The use of SHPL on the CVN-71 demonstrates what high performance networking technology can do for next generation Navy ships, and how networking can extend the useful life of current ships.
