Low Cost Support Structures, with New Advanced Composite Materials Tailored for Ultra-Stable Particl Tracking Detectors

Not Available The main challenge of today's heterogeneous networks is concerned with interoperability, that is, to deliver end-to-end Quality of Service (QoS) among various networking technologies and equipment from different vendors while achieving maximum possible network performance. Standard protocols provide a common ground for the equipment to communicate; however, the network performance is always lower than would be expected from its original network design. The causes of this performance degradation are subtle and can be traced, fundamentally, to a vendor's proprietary design schemes, e.g., packet scheduling, buffering, and call admission control, and inappropriate parameters setting on the network elements and their interfaces. We will investigate these root causes and their associated network design and operational difficulties. Our goal is to develop a Rules-based Expert System (RES) that will provide extensive 'expert experiences', known as knowledge rules, to assist designing and operating highly efficient heterogeneous networks. It will work with HP OPENVIEW or IBM TIVOLI, the Navy Network Management Systems of choice, so that RES can be remotely controlled and operated through a uniform Navy platform. RES will achieve Navy's stringent interoperability goals such as those in the IT-21 and DD-21 programs.
