Introduction
This report analyses the network requirements of a business which operates with different
networks for the five different departments and has the switches of these departments connected
with the adjacent switch in a linear bus topology. The report begins by presenting the scope of the
project and then goes on to summarize the requirements of the network. After that the network
design gets discussed in detail where the topologies and cabling are mentioned. Thereafter, the
report presents the IP addressing and subnet calculation for the different subnetworks and mentions
the key findings [8]. After that the network topology diagram is given and the configuration for
switches, routers, access points, database server as well as the security for the network get talked
about. Following this the report ends with observations in concluding notes.
Solution
Project Scope
The business whose network design is being proposed comprises of five individual
departments each of which is to have a particular network. All the five different departments are to
access the fourth switch which hosts the Ethernet printer and database server along with the
management and employees. Only the Manager from this department is to have access the finance
which department. Other than that the finance department is not to have direct network
connections.
Project Requirements
There are assumed to be a laptop available for each user. Hence number of laptops per
department is 3. Therefore, total number of laptops for all departments equal 15. These laptops are
to be connected through wireless routers that are connected directly to the main router. The
company looks to be a decent sized firm having five different networks for each of its five respective
departments.
Other than that, each of the department is to provide network to 3 workstations [5]. One of
which hosts the database server and the Ethernet printer that needs to be shared among the devices
of all the departments.
Network Design
The network design is chosen to be quite straight forward. Internet is obtained from the ISPs
or Internet Service Providers through the main router [6]. Part of the connections are provided to all
the 15 laptops through a different network via the wireless router WRT300N [1]. The rest of the

4OVERVIEW ON NETWORKING
connections are passed through a firewall from the main router to the switch that is responsible for
providing access to finance department. From here the network follows a linear bus topology to
connect the other switches of the network. For security reasons, direct connections to the finance
department are blocked by the firewall. Only the manager’s system is allowed to have access over
the devices of finance department through the LAN. The cables to connect the switches and in
between the router and the wireless router are crossover cables while for connecting individual
devices the straight through cables have been used.

The CIDR (Classless Interdomain Routing) method of IP addressing is used for allocating IP
addresses [7]. The major network chosen for the network is 172.16.121.0/24 with where about 30%
of the address space is being used suggesting health traffic and decent network performance. An
additional network (172.16.121.72) was required for connection between the main router and the
wireless router
Network Topology Diagram
Figure 1: Network Topology Diagram
Switch Configuration
All the switches of the company are connected with each other in linear bus topology [3].
Since the switches need to support both inbound and outbound connections, the link through which

6OVERVIEW ON NETWORKING
they acquire the network as well as the link with which connections are forwarded to the other
switches are configured to be in trunk mode to operate with both VLANs.
Router Configuration
The main router uses the network for finance department to connect for the interface
to connect with switch01 and the IP address 172.16.121.73 to connect with the wireless
router who uses the interface with IP 172.16.121.74 to receive this connection.
Access point and server configuration
The wireless router itself here performs as the wireless access point for all the laptops and
remote devices requiring wireless connections. The network used for serving wireless network
connections is 172.16.121.32 [4]. The server as well as the Ethernet printer is installed with the
switch that provides network access to Management and Employees department and hence the
server uses IP address 172.16.121.34 from the subnetwork of the management and employee’s
department.
Security configuration
The firewall makes use of two VLANs or Virtual Local Area Networks. VLAN 1 and VLAN 2 for
outbound and inbound connections respectively [2]. The interface through which the firewall, Cisco
ASA 5505 obtains the network accesses the VLAN 1 while the interface through which the server
provides the network to switch01 accesses the VLAN 2.
Conclusion
To conclude, this report successfully analyses network requirements of the business that
operates with different networks for the five different departments and has the switches of these
departments connected with the adjacent switch in a linear bus topology. The report is observed to
be presenting the scope of the project and proceeds further to summarize the requirements of the
network. After that the network design gets discussed in detail where the topologies and cabling are
mentioned. Thereafter, the report presents the IP addressing and subnet calculation for the different
subnetworks and mentions the key findings. After that the network topology diagram is given and
the configuration for switches, routers, access points, database server as well as the security for the
network get talked about.
