+ <p><font size="2" face="Arial">Designing a WAN can be a challenging task, but
+ approaching the design in a systematic manner can lead to superior
+ performance at a reduced cost. Many WANs have evolved over time,
+ therefore many of the guidelines discussed here may not have been
+ considered. Every time a modification to an existing WAN is
+ considered, the steps in this module should be followed. WAN
+ modifications may arise from changes such as an expansion in the
+ enterprise the WAN serves, or accommodation of new work practices and
+ business methods.</font></p>
+ <p><font size="2" face="Arial">Enterprises install WAN connectivity
+ because there is a need to move data in a timely manner between
+ external branches. The WAN is there to support the enterprise
+ requirements. Meeting these requirements incurs costs, such as
+ equipment provisioning and management of the data links.</font></p>
+ <p><font size="2" face="Arial">In designing the WAN, it is necessary to know what data traffic must
+ be carried, its origin, and its destination. WANs carry a variety of
+ traffic types with varying requirements for bandwidth, latency, and
+ jitter. <img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"></font></p>
+ <p><font size="2" face="Arial">For each pair of end points and for each traffic type, information is
+ needed on the various traffic characteristics.
+ <img border="0" src="../../images/2.gif" align="absmiddle" width="12" height="12"> Determining this may
+ involve extensive studies of and consultation with the network users.
+ The design often involves upgrading, extending, or modifying an
+ existing WAN. Much of the data needed can come from existing network
+ management statistics.</font></p>
+ <p><font size="2" face="Arial">Knowing the various end points allows the selection of a topology or
+ layout for the WAN. The topology will be influenced by geographic
+ considerations but also by requirements such as availability. A high
+ requirement for availability will require extra links that provide
+ alternative data paths for redundancy and load balancing.</font></p>
+ <p><font size="2" face="Arial">With the end points and the links chosen, the necessary bandwidth can
+ be estimated. Traffic on the links may have varying requirements for
+ latency and jitter. With the bandwidth availability already
+ determined, suitable link technologies must be selected. </font></p>
+ <p><font size="2" face="Arial">Finally, installation and operational costs for the WAN can be
+ determined and compared with the business need driving the WAN
+ provision.</font></p>
+ <p><font size="2" face="Arial">In practice, following the steps shown in
+ Figure <img border="0" src="../../images/3.gif" align="absmiddle" width="12" height="12"> is seldom a linear
+ process. Several modifications may be necessary before a design is
+ finalized. Continued monitoring and re-evaluation are also required
+ after installation of the WAN to maintain optimal performance.</font></p>
