PHYSICAL NETWORK DESIGNS

The architect lays those elements into a blueprint, which corresponds to the perspicuous jut. At this point, no decisions have been made regarding construction materials, and the layout of the theater may change many times as the client and architect seek to realize a common vision. nearly consideration is given to the final physical appearance--one story or two, possible construction materials--but the general contractor takes the logical invent prepargond by the architect, and makes the physical mark. In this example, the physical design would include where walls pass on be placed, which walls will be load-bearing, how wire will be run, which types of appliances will be installed, and how they will be installed, etc. The logical design may take nigh of these factors into account, and the physical design may reveal some logical aspects that need to be reworked, but the two are assorted processes requiring different skills.

This same approach exists in internet design, as well. The logical design identifies the topology, addressing, switching and routing protocols and even security issues that will be handled by the network ("Interview with," 2003). During this phase of network design, hardware issues or specific hardware is not withal selected, although it is likely that the network designer will have a good idea of what is available to meet the logical design ask.

Physical design follows logical design and consists of identifying the real technologies and products that will fulfill the logical design (McCabe, 2003). During this process, capacity issues are taken into account as well as scalability issues and the needs of the organization in the future with regard to both of these.
