This activity is developing high performance networking technologies to provide enabling technology in support of global climate simulation, high resolution remote imagery exploitation, telemedicine as well as national- and global-scale applications requiring high data-rate wide and local area communication and information services. This activity will produce networking technologies needed to enable the effective interconnection of the high performance computing systems produced by the other parts of the HPCC Program. The Internetworking activity develops technology in four areas: Internet Protocols, Communication Services, Routing and Scaling, and Network Security. Internet Protocols insure that differing types of network "bitways" work together as a cohesive system to build networks from a local to global scale and from slowest to fastest. Research in this area also insures that integration of the newest high performance technology continues to interwork with existing and slower technology in a systematic manner. Routing and Scaling technologies insure that networks continue to provide reliable services as the number of networks and connected endpoints continue to increase. Communication Services builds on the basic transmission capability of the underlying technology to provide additional services, such as multicast and guaranteed Quality of Service, to applications. Finally, the Network Security activity collaborates with the Defensive Information Warfare program to integrate security techniques into the evolving network infrastructure.
The High Performance Networking activity is concerned with satellite, broadcast communication, switching technology, telecommunications standards, optical transmission, and affordable local area designs. This activity develops technology to reduce latency and increase bandwidth by focusing on new techniques to interface computers and their applications to networks, to provide distributed computing services that enables high inter-application performance, and to evaluate and measure performance through continual experimental applications. The objective is to create a suite of complementary communication systems that can be integrated into an overall system with all of the strengths and none of the weaknesses of individual systems. Through the use of testbeds, a continually escalating level of performance for application development is provided while validating the effectiveness of the supporting technologies. |
