WAN Design
This chapter covers wide-area network (WAN) designs for the enterprise WAN and enter-
prise branch architecture. It starts out by reviewing traditional WAN technologies and net-
work topologies. Remote-access design is examined with an emphasis on virtual private
networks (VPN). Next, enterprise VPNs are compared and contrasted with service
provider VPNs. Then, this chapter covers WAN architecture, WAN components, and
