Network Topology - HP 200 Series Services And Applications

ISDN Wide Area Network Design: Dry Creek Joint Elem. School District
Applications
To provide for the exchange of administrative and instructional information,
the three school locations require connection with the district office. In
partnership with Hewlett-Packard, the district has selected a two-phased
strategy using extended local area network (LAN) technology. Phase I
implements access to student administrative applications, electronic mail,
and other office automation applications for a core of trained administrators
and clerical staff.
During the 1993-94 school year, the district will begin phase II by designing
and implementing an integrated instructional computer network, tying all
school instructional areas together in a wide area network with access to
external resources such as the Internet.
Applications
Dry Creek's enterprise network must support office automation applications
such as electronic mail, word processing, graphics, and electronic spread-
sheets, as well as host- and server-based business and student administration
applications. The wide area network also must handle the additional load of
instructional traffic, such as electronic mail and Internet access, when those
services are brought online.

Network Topology

The current network is a star topology with the district office as the center
hub. Currently, the entire district is serviced by Roseville Telephone
Company from one central office. Roseville Telephone Company can provide
either 56 Kbit/s leased digital circuits or basic-rate Integrated Services
Digital Network (ISDN) services. The district's criteria for its wide-area
service are that it must be cost-effective, provide high performance, be
supportable, and provide maximum uptime.
