IKEA Global Strategy EssayIntroductionA mesh that covers a broad playing field (i.e., any telecommunications network that links across metropolitan, regional, national or international boundaries) using leased telecommunication lines. Related terms for other types of networks are personal domain of a function networks (PANs), local area networks(LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, building, campus or specific metropolitan area (e.g., a city) respectively. If you have a large campus network using routers and dynamic routing protocols and an internal infrastructure, you do non necessarily have a WAN. A wide area network (WAN) is a computer network that spans a relatively large geographical area. If your network uses a network infrastructure that is owned by your service provider, holding WAN technologies, you have a WAN. Computers affiliated to a wide-area network are often connected through public networks, such as the telephone system.BodyThe distinguishing features of a WANSending entropy want distancesAlthough distance is non a true criterion for determining whether your network is a WAN, approximately WANs do span a abundant distance, and the technologies used in the WAN depend a great deal on the distances involved. If your WAN spans only a single city, across town is a tenacious way nevertheless, your carrier may choose different technologies for that distance than they would if your network spanned a state, country, or continent. Although long distances are not criteria for defining a WAN, commonly, WANs do span substantial distances.Implementing routing protocolsRouting protocols are also not true criteria for a WAN definition. A WAN can either use manual routing or employ a routing protocol such as RIP or EIRGP. Although larger, more complex networks comparable a national WAN may beeasier to manage when implementing a routing protocol, their use does not ord er that you have a WAN. A large corporation could have a single (but large) building or a campus of several buildings that causes the network to have several routers. To make life easier on the routing front, you could choose to implement one of the many available routing protocols. So, although most WAN environments make use of routing protocols, not all networks that implement routing protocols are necessarily WANs.Using carrier equipmentMeans the equipment from your telephone company that allows you to connect your network to the gritrock of its network. These network connections can be digital subscriber line (DSL), frame relay, fiber optic, broadband cable, or other technology used by your telephone company or network provider. This component genuinely turns a network into a WAN, allowing your traffic to travel mingled with your locations while traversing another providers network, mainly your ISP or telephone company. In some cases, this traffic may cross several providers networks. If you are connecting two offices and they are in different countries, you may be crossing networks owned by a regional provider, which connects to a national provider and then crosses borders and travels across the other national provider to another regional provider before finally reaching your other branch office location. It is this use of other peoples networks that really defines use of a large LAN versus a WAN (LANs are covered in the next section). So, a WAN is not related to the size of your network, or to your choice of routing protocols, or to any other factors.ConsolationHowever, in terms of the application of computer networking protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different LANs, MANs and other place computer networking architectures. This distinction stems from the fact that common LAN technologies operating at Layer 1/2 (such as the forms of Ethernet or Wifi) are often geared towards physically localised networks, and thus cannot transmit data over tens, hundreds oreven thousands of miles or kilometres. This could be to facilitate high bandwidth applications, or provide better functionality for users in the CAN. A CAN, for example, may have a localised grit of a WAN technology, which connects different LANs within a campus. The textbook definition of a WAN is a computer network spanning regions, countries, or even the world.
