and experimental technology, many of these policies and procedures are motivated more by technological considerations or by
a desire to be compatible with the world outside Digital than by traditional Digital procedures.

Naval Engineering will be greatly impacted by the emergence and deployment of the Next Generation Internet (NGI) based
upon the Transmission Control Protocol/Internet Protocol version 6 (TCP/IPv6) family of protocols; Shipboard Information
Technology (IT), IT for the 21st Century (IT-21), the Navy and Marine Corp Intranet (NMCI), and the commercial Internet currently
are built upon the Transmission Control Protocol/Internet Protocol version 4 (TCP/IPv4) family of protocols. The TCP/IPv6
protocol family will likely replace the TCP/IPv4 protocol family after an extended transition period, anticipated at up to 10 years,
during which both protocol families will need to be supported. The replacement of the TCP/IPv4 protocol family is necessary to
ensure the long-term health, scalability, and security of the Internet and DoD Command, Control, Communications, Computers,
Intelligence, Surveillance, and Reconnaissance (C4ISR). The USN, USMC, and DoD should begin preparing for this costly and
complex transition.

The objective of the Next Generation Internet (NGI) Federal program is threefold, encompassing development of networking
technologies, high-performance network testbeds, and revolutionary applications. There have been notable advances in emerging
network technologies and several nationwide testbeds have been established, but the integration of emerging technologies into
applications is lagging. to help bridge this gap between developers of NGI networking technologies and developers of NGI
applications, the NASA Research and Education Network (NREN) project hosted a two-day workshop at NASA Ames Research
Center in August 1999. This paper presents a summary of the results of this workshop and also describes some of the challenges
NREN is facing while incorporating new technologies into HPCC and other NASA applications. The workshop focused on three
technologies - Quality of Service (QoS), advanced multicast, and security-and five major NGI application areas - telemedicine,
digital earth, digital video, distributed data-intensive applications, and computational infrastructure applications. Network
technology experts, application developers, and NGI testbed representatives came together at the workshop to promote cross-fertilization
between the groups. Presentations on the first day, including an overview of the three technologies, application case studies
and testbed status reports, laid the foundation for discussions on the second day. The objective of these latter discussions, held
within smaller breakout groups, was to establish a coherent picture of the current status of the various pieces of each of the three
technologies, to create a roadmap outlining future technology development, and to offer technological guidance to application
developers. In this paper we first present a brief overview of the NGI applications that were represented at the workshop, focusing
on the identification of technological advances that have successfully been incorporated in each application and technological
challenges that remain. Next we present the technology roadmaps that were created at the workshop, summarizing the status of
various mechanisms that are currently under development and forecasting when various advances are likely to occur within the
next one-to-three-year time span. Then we identify issues that were raised at the workshop that might hinder technology development
or that might impede integration into NGI applications. We also report some specific guidelines that were offered at the workshop
to enable application developers to integrate and effectively use emerging NGI technology building blocks. Finally, we
describe NREN activities to incorporate emerging technologies into NASA applications. These activities include support for other
NASA High-Performance Computing and Communications Program areas such as IPG (Information Power Grid), support for
NASA science enterprises such as Earth science and Mars program prototyping activities, support for satellite/terrestrial networking
applications such as the TransAtlantic and TransPacific demonstrations and the Interplanetary Internet, support for NASA
telemedicine applications such as the Virtual Collaborative Clinic, and participation in NGI advanced technology testbed initia-
