IKEA Global Strategy EssayIntroductionA entanglement that coers a broad ambit (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 area networks (PANs), local area networks(LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, construct, campus or specific metropolitan area (e.g., a city) respectively. If you have a outsize campus network using routers and dynamic routing protocols and an internal infrastructure, you do not necessarily have a WAN. A wide area network (WAN) is a ready reckoner network that spans a relatively large geographical area. If your network wasting diseases a network infrastructure that is owned by your service supplier, implementing WAN technologies, you have a WAN. Computers connected to a wide-area network are often connected through public networks, such as the telephone system.BodyThe distinguishing features of a WAN direct data long distancesAlthough distance is not a true criterion for determining whether your network is a WAN, almost WANs do span a immense 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 long way nevertheless, your carrier may choose several(predicate) 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 implement a routing protocol such as RIP or EIRGP. Although larger, more complex networks like a national WAN may beeasier to manage when implementing a routing protocol, their use does not dictate th at 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 backbone of its network. These network connections can be digital subscriber line (DSL), frame relay, fiber optic, broadband cable, or another technology used by your telephone company or network supplier. This component really turns a network into a WAN, allowing your traffic to travel between 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 ready reckoner 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 localise computer networking architectures. This distinction stems from the fact that common LAN technologies direct at Layer 1/2 (such as the forms of Ethernet or Wif i) are often geared towards physically localised networks, and thus cannot transmit data over tens, hundreds or hitherto thousands of miles or kilometres. This could be to facilitate higher bandwidth applications, or provide better functionality for users in the CAN. A CAN, for example, may have a localised backbone 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.
