Exhibit D. -- ED Internet Computing and Networking Infrastructure, Equipment, and System and Server Software as of October 1997

The following sections present the configuration and component specifications (as of October 1997), as well as the scalability requirements in the area of hardware, software, and communications services for the ED Internet site.

ED Networking Environment

The diagram in the figure below describes the network topology in which the ED Internet site will be hosted. The major features of the topology are the links to two separate ISPs and a firewall consisting of a Sun Ultrasparc server running Checkpoint Firewall-1 software.

Internet Hardware and Software

The following list itemizes only the major components of the current configuration for the INet system, which includes the main ED addresses www.ed.gov, gopher.ed.gov, ftp.ed.gov, easi.ed.gov, oeri.ed.gov, oeri2.ed.gov, inet.ed.gov, and nle.ed.gov. It does not include gcs.ed.gov, stw.ed.gov, sfa.ed.gov, nces.ed.gov, other UNIX and Windows NT-based Internet servers, firewalls, mail gateways, virus checkers, and DNS servers located in Regional Office Building No. 3 (ROB-3).

Not all software is used in the production environment; some is used only on the test site.

Scalability and other requirements for listed hardware include anticipated need for upgrades to current configuration to allow for:

•	more concurrent users

•	larger data holding (eventually archive system required)

•	increased processing complexity - in relationship to search capabilities particularly

•	security requirements to be met

The Department intends to implement the following software upgrades by February 1998:

•	upgrade the operating system for all four servers listed below to Solaris 2.5.1, and eventually to Solaris 2.6 for Year 2000 compliance

•	replace the Galacticomm "the Major for UNIX" BBS software -- which only runs on Solaris 2.4 -- with software of equivalent functionality, i.e., user self-registration, sysop-controlled user privileges, discussion forums, file upload/download, and access to ED web site (different from Galacticomm access to ED gopher site)

•	replace the Xchange software -- which only runs on SunOS -- with software that provides the subset of functionality necessary for registered INet users, i.e., user logon/password access control, email, menu access to host-based client software

Additional Hardware

•	HydraWeb Load Balancing System (balances public access load directed to www.ed.gov between two machines -- oeri.ed.gov and oeri2.ed.gov)

•	Hard Disk Drive Tower + Data Silo standalone expansion cabinets (disk space included in server totals above)

•	Two (2) Xylogics terminal servers + 4 breakout boxes (Only one terminal server currently installed)

•	Equipment and modem racks

Additional Software

•	Desktop based client software for e-mail, Web browsing, gopher, ftp, telnet, and helper applications

•	Various Windows/DOS, Macintosh, and UNIX desktop tools for contractor staff to use to:

--	edit and prepare documents (WordPerfect, Microsoft Word, Excel, Powerpoint, Lotus 1-2-3, Lotus Freelance, Adobe PageMaker, HTML Transit, etc.)

--	convert text, tables, and graphics from various software formats to standard Internet formats (HTML, GIF, JPEG, ASCII)

--	create and edit graphics (Adobe Photoshop, Lview, etc.)

•	Various utilities and applications developed by INet contractor for:

--	usage log analysis and reporting

--	document conversion, validation, naming, and indexing

--	gopher-on-the-fly (on-demand generation of ASCII text files from HTML equivalents to respond to requests from gopher users)

--	Custom scripts using C, Perl, JAVA, JavaScript, and other UNIX scripting languages and utilities to process form input and build HTML pages, format and email input data, etc.

--	Cron jobs

Software must be upgraded from time to time to meet new or enhanced service requirements, correct problems, increase capacity, and expand concurrent use licenses, as well as to test and experiment with new capabilities.
