+ legal reasons, a communications provider or a common carrier normally
+ owns the data links that make up a WAN. The links are made available to
+ subscribers for a fee and are used to interconnect LANs or connect to
+ remote networks. WAN data transfer speed (bandwidth) is considerably
+ slower than the 100 Mbps that is common on a LAN. The charges for link provision are
+ the major cost element of a WAN and the design must aim to provide
+ maximum bandwidth at acceptable cost. With user pressure to provide more
+ service access at higher speeds and management pressure to contain cost,
+ determining the optimal WAN configuration is not an easy task.</font></p>
+ <p><font face="Arial" size="2">WANs carry a variety of traffic types
+ such as data, voice, and video. The design selected must provide
+ adequate capacity and transit times to meet the requirements of the
+ enterprise. Among other specifications, the design must consider the
+ topology of the connections between the various sites, the nature of
+ those connections, and bandwidth capacity. </font>
+ </p>
+ <p><font size="2" face="Arial">Older WANs often consisted of data links
+ directly connecting remote mainframe computers.
+ <img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"> Today’s
+ WANs, though, connect geographically separated LANs.
+ <img border="0" src="../../images/2.gif" align="absmiddle" width="12" height="12"> End-user
+ stations, servers, and routers communicate across LANs, and the WAN data
+ links terminate at local routers. By exchanging Layer 3 address
+ information about directly connected LANs, routers determine the most
+ appropriate path through the network for the required data streams.
+ Routers can also provide quality of service (QoS) management, which
+ allots priorities to the different traffic streams.
+ </font>
+ </p>
+ <p><font size="2" face="Arial">Because the WAN is merely a set of
+ interconnections between LAN based routers, there are no services on the
+ WAN. WAN technologies function at the lower three layers of the OSI
+ reference model.
+ <img border="0" src="../../images/3.gif" align="absmiddle" width="12" height="12"> Routers
+ determine the destination of the data from the network layer headers and
+ transfer the packets to the appropriate data link connection for
+ delivery on the physical connection.</font></p>
