Network Design - Essay Example In the following section a description of both physical and logical design is given to clearly define the distinction between these two approaches. logical network design refers to the logical addressing used to describe the network or the networks it connects to. A logical network design displays the IP Addresses linked with each component of the network as shown in fig. 2. In most cases, the logical network is a simple Class C network such as 192.168.0.0 with the default subnet mask of 255.255.255.0. This network allows up to 254 hosts to be connected directly to it without the need of any routing. The following are important factors involved in logical network design. Information about client Kinds of Services or Applications Will the Network Offer Choice of LAN Protocol The information and assessment about the work patterns for various clients is an important factor in logical network design. It helps to appropriately place servers, high- bandwidth links, and other such things in the appropriate physical location of the network. For example if any client (either a single work station or a group) contributes a major portion of the network traffic, then it is necessary to provide that client with a large data pipe. The second important point to be considered in network’s logic design is the kinds of services or applications that a can offer. Typical network applications today include FTP, telnet, and, of course, browsing the Web. Since each application has potential security problems, hence logical network design also addresses the potential security risks. The choice of LAN Protocol is also decided in logical network design. Today the de facto protocol of choice has to be TCP/IP.
