Today's network administrators must
manage complex wide-area networks (WANs) in order to support the
growing number of software applications that are built around Internet
Protocol (IP) and the Web. These WANs place a great demand on network
resources, and require high-performance networking technologies. WANs are complex
environments that incorporate multiple media, multiple protocols, and
inter-connection to other networks, such as the Internet. Growth and
manageability of these network environments are achieved by the often
complex interaction of protocols and features.
Despite improvements in equipment
performance and media capabilities, WAN design is becoming more
difficult. Carefully designing WANs can reduce problems associated
with a growing networking environment. To design reliable, scalable WANs,
network designers must keep in mind that each WAN has specific design
requirements. This chapter provides an overview of the methodologies
utilized to design WANs.

Washington
Project: WAN Design
In
this chapter, you will learn about WAN design
processes that will enable you to implement WAN
services requirements into the Washington School
District network design. The district WAN should
connect all school and administrative offices with
the district office for the purpose of delivering
data.
