IKEA Global Strategy Essay

IntroductionA net income that covers a broad area (i.e., any telecoms ne bothrk that cogitate across metropolitan, regional, national or international boundaries) using leased telecommunication courses. Related terms for other types of networks are personal area networks (PANs), local anesthetic area networks(local area networks), campus area networks (CANs), or metropolitan area networks (MANs) which are unremarkably limited to a room, building, campus or specific metropolitan area (e.g., a city) respectively. If you have a lifesize campus network using routers and dynamic routing communications protocols and an inbred infrastructure, you do non needs have a na mathematical functionous. A tolerant area network (WAN) is a ready reckoner network that spans a relatively too large geographical area. If your network uses a network infrastructure that is have by your service provider, implementing WAN technologies, you have a WAN. Computers connected to a wide-area network a re often connected through public networks, such as the telephone system.BodyThe distinguishing features of a WANSending selective information long distancesAlthough distance is not a true criterion for determine whether your network is a WAN, most WANs do span a big distance, and the technologies use in the WAN depend a great escape on the distances involved. If your WAN spans only a single city, across townspeople is a long way nevertheless, your carrier may choose dissimilar 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 in any case not true criteria for a WAN definition. A WAN depose either use manual routing or implement a routing protocol such as RIP or EIRGP. Although larger, more complex networks akin a national WAN may beeasier to manage when implementing a routing protocol, their use does not dictate 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 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 provider. This component in truth turns a network into a WAN, allowing your traffic to travel between your locations time traversing another providers network, mainly your ISP or telephone company. In some cases, thi s traffic may cross several providers networks. If you are connecting two offices and they are in dissimilar countries, you may be crossing networks have 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 succeeding(prenominal) section). So, a WAN is not related to the size of your network, or to your prize of routing protocols, or to any other factors.ConsolationHowever, in terms of the natural covering of computer networking protocols and concepts, it may be best to view WANs as computer networking technologies used to aerate data over long distances, and between different LANs, MANs and other localised 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 assist 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.
