A.1.0 INTRODUCTION
The World Wide Web (WWW) is growing rapidly on the Internet network and is slated to quadruple by the year 2000. With the increasing versatility and capability of the WWW, collaboration tools that facilitate the sharing of documents, transfer of speech over the Internet, and the ability to communicate using video techniques have surfaced and have recently assumed significance. The DCN/ICN bases a lot of its functionality on the ability to collaborate in systems design, analysis, integration and support in a CALS environment. With the multitude of types of computers and their specific hardware, it is important and necessary to classify the tools and their functionality for various hardware platforms. Furthermore, the subscriber services offered by the DCN/ICN will be based on core, intermediate and advanced services, each with increasing levels of capability. Given this situation, it is important that a client workstations' hardware meets the overall requirements of the collaboration tools that it must support for being a DCN/ICN node.
This section will outline various workstation and server qualification matrices for the support of these collaboration tools and the functions that are needed for the DCN/ICN to function effectively.
A.2.0 CLIENT WORKSTATION REQUIREMENTS
The multitude of platforms and their specific hardware requirements mandated the generation of the following matrices that are organized in the tier of functionality offered by the DCN/ICN, namely the core (using ASCII Terminals), intermediate (Graphical Workstation) and advanced (Full Multimedia and Development) levels. Each service level has been further broken down into the various generic operating systems and hardware platforms that are available in the industry. We have outlined also the variety of applications that the service levels encompass.
A.2.1 DCN/ICN Core Service requirements
The DCN/ICN core service requirements include the following services/capabilities:
· Electronic-Mail.
· Newsgroups/Forums.
· WWW browser (Text - e.g., LYNX).
· Events, white pages, yellow pages.
· Core Training.
A.2.2 Core (ASCII Terminal Minimum Requirements)
The core level is the fundamental service offered by the DCN/ICN pilot program. This level of service is meant for the subscriber that would like to take a maximum of advantage of the CALS information content offered by the DCN/ICN repository. To take optimal advantage of the core level of service, the client system should be capable of handling E-Mail, newsgroups, events, white and yellow pages, core training, and WWW browsing in a text/graphics based operating environment.
A.2.2.1 Terminal Requirements
Many terminals can meet the basic needs of the DCN/ICN core services. The terminal specifications given below can be used as a general baseline example of a quality client. The terminal must be versatile enough to work in most environments, such as PC, Macintosh or UNIX hosts. The hosts must be connected to the Internet network through either dial up (analog or ISDN) or direct network connect. It must have a choice of emulations and compatibility with many operating systems such as UNIX, VMS, ULTRIX, Pick, Theos. It should support DEC and PC Multinational character sets. A terminal with the following characteristics would suffice.
· Very fast communications speed (up to 11 5.2K bps,. up to 38.4k bits per second)
· Compatible with wide range of operating systems
· User friendly, window-like setup
· Easy installation
· Minimum 14" flat screen with overscanned video, in green, amber or paper-white phosphor
· Sessions: Single Session

A.2.3.4 Audio Conferencing Tools Matrix
Audio capability over the Internet is fast becoming an alternative to standard telephones as the quality and clarity of speech supported by the tools greatly improve. The DCN/ICN supports Internet audio collaboration products for the delivery of voice in real time to give a higher level of collaboration/interaction between the parties. In support for this goal, Table A.2.3.4-1 summarizes the features of some of the audio tools available in the market today. It must be noted that the tools listed in the matrix do not all have the same level of functionality, nor the same audio quality. In our experience, we have had success with a limited set from this matrix.
Preliminary testing of some of these products has been performed. The current preferred list of DCN/ICN audio capable tools are highlighted in red.
