Satellite Networks &
Architectures Branch

The concept of Global Information Infrastructure (GII) is to provide access to a set of
communication services, that is an open multitude of information-based applications
and services, to everyone, anytime, anywhere at acceptable cost and quality. This can be
achieved by the seamless interconnection of all networks, information systems, and
applications. Satellite communications play an important role in providing access to
communication services at the global level, and it has become increasingly evident that
there is a need to develop an architectural framework within which information-based
applications can realize their full potential. Also, such a framework will be useful for
standards, experiment design, and strategic planning. We are developing approaches
to frameworks based on end-users, enterprise networks, service providers, and satellite network operators.
We also participate in discussions about the architecture frameworks being
developed by various standards-making bodies (ITU, ANSI, ATM Standards, etc.) and their
pros and cons. From this foundation of cooperation, research, and development, we
will answer the need for a higher level systems
engineering approach for development of architectural framework for the next-generation
satellite networks.
