+
+ Many enterprise WANs will have connections to the Internet. This
+ poses security problems but also provides an alternative for
+ inter-branch traffic.<p>Part of the traffic that must be considered during design is going to
+ or coming from the Internet. Since the Internet probably exists
+ everywhere that the enterprise has LANs, there are two principal ways
+ that this traffic can be carried. Each LAN can have a connection to
+ its local ISP, or there can be a single connection from one of the
+ core routers to an ISP. The advantage of the first method is that
+ traffic is carried on the Internet rather than on the enterprise
+ network, possibly leading to smaller WAN links. The disadvantage of
+ permitting multiple links, is that the whole enterprise WAN is open to
+ Internet-based attacks. It is also difficult to monitor and secure the
+ many connection points. A single connection point is more easily
+ monitored and secured, even though the enterprise WAN will be carrying
+ some traffic that would otherwise have been carried on the Internet.<p>If each LAN in the enterprise has a separate Internet connection, a
+ further possibility is opened for the enterprise WAN. Where traffic
+ volumes are relatively small, the Internet can be used as the
+ enterprise WAN with all inter-branch traffic traversing the Internet.
+ <img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"> Securing the various LANs will be an issue, but the saving in WAN
+ connections may pay for the security.<p>Servers should be placed closest to the locations that will access
+ them most often. Replication of servers, with arrangement for off-peak
+ inter-server updates, will reduce the required link capacity. Location
+ of Internet-accessible services will depend on the nature of the
+ service, anticipated traffic, and security issues. This is a
+ specialized design topic beyond the scope of this curriculum.
