The Washington School District WAN should connect all school and administrative offices with the district office for the purpose of delivering data.

The WAN technology required for the Washington District WAN's link to the Internet is a frame relay PVC running at T1 speed.

PPP encapsulation should be used on point to point links in the Washington School District network.

The Washington School District should use dedicated lines (T1) for its WAN core.

The WAN core for the Washington School District network should be a high-speed switching backbone designed to switch packets as quickly as possible. School locations should connect into the WAN core based on proximity to the core from school locations.

The Washington School District WAN should be based on a two-layer hierarchical model. Three regional hubs should be established - one each at the district office / data center, the service center, and Shaw Butte Elementary School to form a fast WAN core network.

Internet access and connections any outside network should be provided through the Washington School District office by using a Frame Relay Link. For security purposes, no other connections should be permitted.

PPP should be used as the data-link layer protocol in the district WAN implementation.

An ISDN connection must be provided for a remote site that needs part-time connectivity to the district.
