And in Chapter 2, Overview of Network Topologies, you learned about the various topologies you can employ when designing and creating a local neighborhood network (LAN), and we also looked at some scenarios in which several networks were committed to form a wide area network (WAN). In this chapter, we volition look at an different aspect of creating a network the networks logical and physical design. The physical aspects of your LAN will depend on the vestigial physical transport technologyEthernet or Token-Ring, for example, or possibly ATM, which is forthwith 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 more 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 used for the most part in vertical-market applications (such as on the factory floor, or for point-of-sale hard cash registers). If you dont need the features that TCP/IP provides, and dont need an mesh connection, then these senior protocols may be a good solution for your network. Novell s NetWare products, while allowing for averse compatibility with the IPX/SPX protocol, have finally caught up with the times, and new installations will more than possible use the IP protocol. Other protocols, such as Microsofts LAN Manager, are used only in older networks. If you are still development older proprietary protocols, you should consider upgrading to TCP/IP, which is now the de facto standard, from the worldwide Internet down to the LAN.Before you can begin to design a physical network, however, you first must determine your needs. What services must you provide to your exploiter community? What are the resources youll need? If you have to compromise, what will it take to recompense the most users or to provide the more important services?
