The company mentioned in the case is AdviceNet which is operating in the consulting and management services industry. The operations of the company are expanded over a wide geographic range including regions likeToronto,New York,Los Angeles,DallasandAtlanta. with future locations of operations to include Vancouver and Chicago. Therefore the regions of operations for the company extend to different major cities in the north and central region of US andCanada. The company is also seeking to increase its modem size and therefore increase the bandwidth which is available to it on its prospective WAN.
The WAN based network is suitable for AdviceNet as it is dynamic in nature, specific to the access points based on the internet, MANs and local LANs.
“A major factor impacting WAN design and performance is a requirement that they lease communications circuits from telephone companies or other communications carriers. Transmission rates are typically 2 Mbps, 34 Mbps, 45 Mbps, 155 Mbps, 625 Mbps (or sometimes considerably more). Numerous WANs have been constructed, including public packet networks, large corporate networks, military networks, banking networks, stock brokerage networks, and airline reservation networks. Some WANs are very extensive, spanning the globe, but most do not provide true global coverage. Organizations supporting WANs using the Internet Protocol are known as Network Service Providers (NSPs). These form the core of the Internet.” (Fairhurst, 2001)
