Techniques for Processing TCP/IP Flow Content in Network Switches at Gigabit Line Rates

The growth of the Internet has enabled it to become a critical component used by businesses, governments and individuals. While most of the traffic on the Internet is legitimate, a proportion of the traffic includes worms, computer viruses, network intrusions, computer espionage, security breaches and illegal behavior. This rogue traffic causes computer and network outages, reduces network throughput, and costs governments and companies billions of dollars each year. This dissertation investigates the problems associated with TCP stream processing in high-speed networks. It describes an architecture that simplifies the processing of TCP data streams in these environments and presents a hardware circuit capable of TCP stream processing on multi-gigabit networks for millions of simultaneous network connections. Live Internet traffic is analyzed using this new TCP processing circuit

Assessment of avionics technology in European aerospace organizations

This report provides a summary of the observations and recommendations made by a technical panel formed by the National Aeronautics and Space Administration (NASA). The panel, comprising prominent experts in the avionics field, was tasked to visit various organizations in Europe to assess the level of technology planned for use in manufactured civil avionics in the future. The primary purpose of the study was to assess avionics systems planned for implementation or already employed on civil aircraft and to evaluate future research, development, and engineering (RD&E) programs, address avionic systems and aircraft programs. The ultimate goal is to ensure that the technology addressed by NASa programs is commensurate with the needs of the aerospace industry at an international level. The panel focused on specific technologies, including guidance and control systems, advanced cockpit displays, sensors and data networks, and fly-by-wire/fly-by-light systems. However, discussions the panel had with the European organizations were not limited to these topics

Applications of remote sensing data in Alaska: A cooperative program of the University of Alaska with user organizations, including local, state and federal government agencies

The development of the coastal-zone-related issues is generating an increasing need for information which is greater in quantity of natural resource data, greater in quality of detail of data, and more frequent in collection of data owing to the need to monitor certain aspects of programs. The array, detail, and frequency of information acquisition required to develop natural resources and to implement and maintain the resulting programs demand improved techniques of data gathering, processing, and interpretation which is conducive to the use of remote-sensing techniques. As Alaska, both in the state and federal domain, gears up to meet the energy-related issues facing the nation there will be a growing role for efforts which adapt state-of-the-art tools to solving existing problems

The summary and baseline change list is included along with design notes for the spacecraft system, thermal subsystem, power subsystem, communications subsystem, plasma wave instrument interface definition, and the structure

A grid-aware emergency response model for natural disasters

Natural phenomena are essential and unavoidable planetary actions. When they occur in extreme forms they may have a disastrous impact on human life, property and the environment. Emergency management bodies mitigate, prepare for, respond to and recover from such events. Emergency response is a sum of decisions and actions taken through the collaboration and cooperation of many specialists from different disciplines. However, primary and secondary research findings suggest that there are limitations in the current information and communication technologies (leT), which affect the effectiveness and efficiency of emergency response tasks. Therefore, the focus of this research was to investigate whether the appropriate use of cutting-edge leT (such as the Grid) can improve the effectiveness and efficiency of emergency response operations for natural disasters. The approach adopted in the research involved literature reviews, case studies, face-toface structured interviews with emergency management stakeholders and leT experts, model development using Soft Systems Methodology (SSM) linked to Information Systems Development Methodologies (lSDMs), and finally, one-to-one evaluation exercises. ease studies and interviews involving two member states of the European Union were carried out to investigate current practices and to highlight the limitations that emergency management stakeholders face during response operations. SSM was used to investigate the problem area and to produce a conceptual Emergency Response Model (ERM). Further literature review and interviews suggested the Grid as the most appropriate technology to support the ERM. The linking together of the SSM findings with ISDMs - resulted in the production of a Grid-Aware Emergency Response Model (G-AERM) for natural disasters. The evaluation of the G-AERM demonstrated the applicability of Grid technology to emergency response by supporting stakeholders in monitoring, planning, controlling and managing actions within emergency situations caused by natural disasters in a far more informed way in terms of effectiveness and efficiency....EThOS - Electronic Theses Online ServiceGBUnited Kingdo
