DATA COMMUNICATIONS AND NETWORKS
Part A:
Analysis of the User requirements:
After investigatuion of the requirements and challenges put forwarded by the new
requiremetns and branch office purchased by AML the following network designhas been
identified. The main goal of designing is to provide the maximum performance along with
maximum avilability, speed and over all, maximun security to serve your groing orgaization’s
needs.
The selected network topology for AML is a star Topology. In the star topology the
Devices are seen to have a connection back to the cetral device in an independent manner.
Break in the cable is only associated with effecting those devices only which are connected
by making use of the broken cable and not by the entire topology. Besides this the third floor
would be associated with hosting 30% of the AML personnel and would be associated with
including the seveteen different work stations consisting of printers along with two network
copiers which would be associted with allowing the scanning as well as the priantable
capabilities and the conference rooms consiting of video conference. Additionally there
would exist an local file server along with an databse server, proxy server, a firewall and a
network management station. The workstation which are left out would be associated with
even dispersal based upon the space in the 2nd floor. The remaining florrs would be associated
with the hosting of the remining personnel and would be associated with including the thirty
work stations along with Voice over IP phones, small rrom for meeting and two printers. For
the purpose of providing wireless coverage to the employees all the floors would be having a
wireless access points which would be helping in getting connected to the switches which are
located in the corresponding floors.

Because of the infrastructure of the buliding it is essentail to make sure that all the
cables are running over the cable and the cable that is to be used is the unsheilded twisted pair
plenum catgory 5e that is CAT5e. the reson behind selection of this cable is that it doesnot
emit any kind of poisonous gas by menas of the buildings heating or ventilation of due to the
air conditioning which is een to happen in the UTP cables. The cables would be running from
each of the workstations through the celling and would be connected to the switches. Besides
this the cables from the 3rd floor would be running throught the 2nd floor by means of the
elevator gap and would be connected to the router or the firewall which would then be
coonected to the service provider. The switch would be used in the 1st floor so as to connect
all the workstations as well as the phones, network printers and conference room to the
network. The switch in turn would get connected to the router or the firewall and for creation
of the demilitarize zone for the local servers a 2nd switch would be used for handling of the
traffic for the local server and this in turn would be connected to the firewall or to the router.
The router in turn would be providing a connection to the wireless access points which is to
be installed in each floor.
B. Description & Analysis of Current Setup
Analysis:
The utilization of a star network topology and the use of switches for each floor
facilitate troubleshooting and repairing broken wires. Additionally, it distributes traffic
among three different switches and in the event of a switch failure; it would only affect the
subnet connected to the device and not the entire network. The same scenario is not true
when it comes to the router/firewall device, since it’s the back bone of our network and a
single point of failure, the team as a secondary router on site and already configured to take
over in case the active router fails.
