THREADED CASE STUDY OVERVIEW

The objective of this case study is to meet the requirements of the Washington School District by designing an enterprise-wide network which will include Local Area Networks (LANs) at each site and to provide data connectivity between all school sites by including a Wide Area Network (WAN).

The implementation of this design will include access to the Internet from any site in the school district .  The school district will implement a series of servers to facilitate online automation of all of the district's administrative and many of the curricular functions.

The network will need to continue to be functional for a minimum of 7-10 years.  Therefore, all design considerations will include a minimum of 100x(times) growth in the LAN throughput, 2x(times) growth in the WAN core throughput, and 10x(times) growth in the District Internet Connection throughput.  The minimum requirement for initial implementation design will be 1.0 Mbps to any host computer in the network and 100 Mbps to any server host in the network.  TCP/IP (Layer 3) and Novell IPX (Layer 4) will be the only two OSI layer protocols allowed for implementation in this network.
