And in Chapter 2, Overview of Network Topologies, you acquire about the various topologies you can employ when designing and creating a local ara network (local area network), and we also looked at some scenarios in which some(prenominal) networks were connected to form a wide area network (WAN). In this chapter, we will look at another aspect of creating a network the networks logical and physical design. The physical aspects of your LAN will depend on the underlying physical transport technologyEthernet or Token-Ring, for example, or perhaps ATM, which is now supported in products such as Windows 2000/XP and Server 2003 as a LAN protocol. Depending on which technology you use, there will be one or much LAN topologies from which to choose.NOTEAlthough there are other LAN technologies, such as ARCnet and Novells IPX/SPX, these are basically legacy products that are no longer being deployed in newer networks. For example, ARCnet is now utilise mostly in vertical-market applications (such as on the factory floor, or for point-of-sale cash registers). If you dont need the features that TCP/IP leave alones, and dont need an Internet connection, and then these older protocols may be a good solution for your network. Novells NetWare products, temporary hookup allowing for backward compatibility with the IPX/SPX protocol, have finally caught up with the times, and new installations will more than likely use the IP protocol. Other protocols, such as Microsofts LAN Manager, are used only in older networks. If you are motionless using older proprietary protocols, you should consider upgrading to TCP/IP, which is now the de facto standard, from the intercontinental Internet down to the LAN.Before you can begin to design a physical network, however, you first must determine your needs. What operate must you provide to your user community? What are the resources youll need? If you have to compromise, what will it fix to satisfy the most users or to provide the more important services?
