IKEA Global Strategy Essay

IntroductionA network that covers a broad discip p atomic number 18nthood (i.e., any telecommunications network that links crosswise metropolitan, regional, national or international boundaries) victimization leased telecommunication lines. Related foothold for otherwise types of networks are personal field of force 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 exact a oversize 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 computer network that braces a relatively large geographical area. If your network uses a network infrastructure that is owned by your service provider, implementing WAN technologies, you have a WAN. Computers connected to a wide-area network are often connected through public networks, such as the predict system. tree trunkThe distinguishing features of a WANSending data long outstripsAlthough distance is not a true quantity for determining whether your network is a WAN, most WANs do span a great distance, and the technologies used in the WAN depend a great deal on the distances involved. If your WAN spans only a integrity city, across town is a long 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 bottomland either use manual routing or implement a routing protocol such as draw or EIRGP. Although larger, more complex networks like a national WAN may beeasier to jazz when implementing a routing protocol, their use does not dictat e 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 conduct life easier on the routing front, you could choose to implement one of the many available routing protocols. So, although most WAN environments coif use of routing protocols, not all networks that implement routing protocols are necessarily WANs.Using carrier equipmentMeans the equipment from your telephone participation 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 really turns a network into a WAN, allowing your craft 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 itemors.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 give 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 or nevertheless 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 schoolbook definition of a WAN is a computer network spanning regions, countries, or even the world.
