WAN Design 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
