Logical Topology

The figure shown is the logical layout of the whole network of the school. This figure shows how the computers are connected to the MDF of the network. It also shows the three major hierarchical network design layer of the network (Core layer, Distribution layer, and Access Layer).

There are only two kinds of cable that comprise the layout; CAT 5e UTP cable and an outdoor CAT 5e UTP cable.

The MDF is composed of a multilayer switch, a 24-port switch, an FTP server, the administrator’s computer and the router for the connection to the ISP. It is also illustrated in the figure that every section is assigned to a specific Virtual LAN by the researchers. The IP addressing is also included to show the addressing assigned by the researchers to the different areas.

In addressing the different users, the proponents used different Virtual LANs to group our users based on the restrictions and privileges that they should have. The Virtual LANs are assigned to the multilayer switch for easy manageability of the network administrator. Student users are assigned to a different Virtual LAN in order to separate them with the other area that may have different privileges and restrictions like the faculty and administrators, all with different Virtual LANs depending on the needs of these areas. In creating the Virtual LANs, the researchers also considered the future growth of the locale. Another reason of having different Virtual LAN for each department is the anticipation of the increase in the number of users. If the additional users are to be added, it will not be applicable to have one Virtual LAN for different department because it will be more difficult to organize and manage them since they are included in one Virtual LAN and they are having different functions. In addition, each department will be using different systems and programs accordingly.
