To assess the effectiveness of HUDs planning requirements, this study explores how communities of different types have documented housing needs over the course of the 1990s; how their housing plans relate to local needs, priorities, and market conditions; and how these plans have shaped federally funded housing activities. More specifically, the Urban Institute conducted case studies of selected city and suburban jurisdictions in six metropolitan areas, including extended field visits to more fully understand local plans and activities in the context of market conditions and trends. The findings and policy implications presented in this report are drawn from these individual case studies. Our approach to this research involved four basic steps. These are: Select study sites that reflect important variations in market conditions and trends; Prepare a preliminary analysis of housing needs, plans, and activities for each site; Conduct field visits to investigate relationships between needs, plans and activities; and Draw cross-site lessons and policy implications from the metro-area case studies.

Fiber Distributed Data Interface, more commonly known as FDDI, is the name of the standard that describes a new local area network (LAN) technology for the 90's. This technology is based on fiber optics communications and, at a data transmission rate of 100 million bits per second (mbps), provides a full order of magnitude improvement over previous LAN standards such as Ethernet and Token Ring. FDDI as a standard has been accepted by all major computer manufacturers and is a national standard as defined by the American National Standards Institute (ANSI). FDDI will become part of the US Government Open Systems Interconnection Profile (GOSIP) under Version 3 GOSIP and will become an international standard promoted by the International Standards Organization (ISO). It is important to note that there are no competing standards for high performance LAN's so that FDDI acceptance is nearly universal. This technology report describes FDDI as a technology, looks at the applications of this technology, examine the current economics of using it, and describe activities and plans by the Information Resource Management (IRM) department to implement this technology at the Savannah River Site.

The Cornell University Castor project was funded over a two-year period to create new technical options aimed at demanding event-notification settings. Applications of this type are common in warfighting and other DoD settings but currently are limited by inadequate scalability, reliability and poor performance. Castor accomplished all goals originally stated in the SOW and in fact went beyond expectations. The team delivered a wide range of cutting-edge solutions, some of which are finding rapid uptake by major AF technology vendors. Our work has received keen interest from the very highest levels of industry, including CTO-level staff at the Air Force itself as well as Intel, Microsoft, Amazon, Red Hat, Cisco and we are collaborating closely with these and other vendors, including IBM and Raytheon. The final status report summarizes accomplishments and includes copies of some of the major publications by our group. Much of the software we developed is available for download from Cornell, as is a video demonstration of the Live Objects technology, which was briefed to the AF CTO, Mr. Kent Werner, in Spring 2008.

The Systems Simulation and Development Directorate has the responsibility for coordinating the research, development, and management of Local Area Networks (LANs) activities within the Missile Research, Development and Engineering Center. Directorates and offices within MRDEC require local computer networks with other LANs and Wide Area Networks (WANs). Networking is essential to evaluate missile computer systems and allow MRDEC access to technology at other DOD sites and worldwide. In support of this effort, UAH was contracted to perform research and analysis of computer networking capabilities within the MRDEC. UAH provided to the Center capabilities for LANs and WANs for missile systems and advanced missile manufacturing.

This report summarizes the activities of a Lab Directed Research and Development (LDRD) Project to investigate the viability of asynchronous transfer mode (ATM) switching technology in the local area network (LAN) environment. A number of ATM based LANs were constructed and their performance capabilities were measured. The summary report notes the measurements and lessons learned from the two-year effort.

Implementing a successful local area network for a publications work-group isn't as simple as the scarcity of information on the subject would suggest. Making a network work for you requires careful planning, developing and acquiring network expertise, transforming your group's patterns of working together, and carefully managing the human and technological resources.

The next generation of tokamaks, ITER or BPX, will be characterized by an even greater emphasis on joint operation and experimentation. With anticipation of an increased number and diversity of collaborations, especially in the area of diagnostics, we are preparing for such shared facilities by developing a systematic approach to remote, joint physics operation involving experimental teams at several locations. The local area network of computers used for control and data acquisition on present and future experiments can be extended over a wide area network to provide a mechanism for remote operation of subsystems (e.g. diagnostics) required for physics experiments. The technology required for high bandwidth ((ge)45Mbps) connections between multiple sites either exists or will be available over the next few years. With the rapid development of high performance workstations, network interfaces, distributed computing, and video conferencing, we can proceed with the development of a system of control and analysis sites to provide for consistent, efficient, and continuing collaborations. Early establishment of such sites could also enhance existing joint design and development efforts.

This thesis presents a technology review of the emerging IEEE 802.11n standard. A wireless local area network (WLAN) based on state-of-the- art equipment supporting the 802.11n protocol is evaluated in the Coalition Operating Area Surveillance and Targeting System (COASTS). This thesis also provides a brief introduction to COASTS, its support for testing various networking schemes, and their effectiveness in supplying information necessary to reach a decision maker's desired end-state. Also provided is a summary of the current state of the 802.11n proposed standard, the hardware and software used to evaluate the equipment, and the testing methodology. In general, the methodology was to conduct field tests with private vendors and coalition partners to evaluate the capabilities of 802.11n networks that promise large throughput benefits for WLANs. The specific goal of this research focused on testing equipment and network configurations in an IP network. The ultimate goal of this research is to evaluate an evolutionary improvement for our forces to transfer large amounts of data and to maintain the mobility and flexibility to deploy rapidly to areas with little or no infrastructure. With this capability our forces may can gain control of the environment, dramatically improve tactical situational awareness, and attain information superiority.
