Project scope
In this project modern network for VIC Warehouse pty Ltd. which consists both wired
and wireless IT infrastructure to connect to its branches located at Footscray,
Ballarat, and Bundoora. The headquarter is located at Melbourne CBD.the host
requirements for the network is given in the table below
Locations Buildings Number of Hosts
Footscray 1 6
2 14
3 22
4 28
Ballarat - 40
Bundoora - 20
The Footscray warehouse consists of four buildings with different hosts
requirements , building 1 has 6 hosts , building 2 has 14 hosts, building 3 has 22
hosts , and building 4 has 28 hosts also the building 4 has marketing and finance
department and the hosts are shared by both of these departments .
There is requirement of wireless access using WIFI routers at each branches. There
should not be any restriction for the employees to use the network they must be
within the company, they should have privilege to access the network from
anywhere an at any time. Also the reliability of the network with the time delay is
very crucial parameter that must be followed strictly by the network engineer as the
customers can order products online, so there must be central server which is
located in Melbourne and it should be secured from any unauthorized access.
Project requirements (Hardware & Software)
 Routers: IP address 172.16.100.0/22 is the internal address of the LAN
network which is to be connected to the internet and other branch network,
to do so we will need routers that will use various routing protocol to route
the data from one network to other. Recommendations are shown in
Appendix A. [1]
 Layer 3 Switch: it is similar to routers when we are routing data from local
area network to other networks. It is also helpful in DHCP protocol to allocate
the IP address to the network.
 Switch: switch is a multiport networking device connecting all the local hosts
like PCs in a star topology, it works in OSI model layer 2 with MAC address
 PCs: the end point user interaction devices havingRJ45 connectors inbuilt and
network interface cards. [5]
 Wireless devices: the laptops and tablets are to be connected with WLAN
devices working in IEEE802.11 WIFI protocols. [7]

Network Topology Diagram
The network topology diagram is the connectivity diagram of each networking
devices with each other in the local area network. The diagram shown below is the
demonstration of the network infrastructure which is proposed for the company as
per there requirements. The branches located at Footscray , Ballarat,and Bundoora
are connected via routers and ISP , that is provided by the internet service providers
as the data is going out of LAN to internet . The routers are connected with the
switches and then the switches connects the end hosts. All the IP address or logical
address are used within the LAN are license free network address and thus
whenever the data flows out or is received by the LAN from ISP routers NAT
(Network Address translation ) protocol is invoked to know exact location of source
and destination. The topology proposed here is star topology as it is most reliable
and secure infrastructure, whenever there is fault between any end devices the
other network is not disturbed. [1]
The result of the structure configuration is a lot of outlines that give a physical
format to the majority of this data and demonstrate the connections among
segments of the structure . One huge contrast between a structure plan and a
system configuration is that there is frequently an imaginative part to a structure
plan, while there is once in a while one for a system structure. There can be an
imaginative part to a system, for example, when it is a piece of a display, show, or
meeting; be that as it may, most by far of systems isn't seen by its clients.[2]

IP address for the organization
The logical address of all the layer 3 device in OSI model is crucial in any network
design architecture, the IP address can be classful or classless, here we are using
classless IP address as subnetting used in this case does not require any specific
mask, and it can be variable. The 172.16.100.0 network address used here is a
public

Detailed Network Design in Packet Tracer
Switch configuration is Cisco packet tracer
VLAN configuration in switch
The VLAN is the backbone of modern computer network architecture as the large
local area network is very difficult to manage, it is bifurcated using VLAN. The
network is said to be consisting of single network when a large organization is using
same set of network ID and managing the network centrally, this reduces the cost
and work of the network engineering also controlling and securing the network
becomes easier. The NAT or network address translation is other protocol which is
very handy to manage the network when using private IP address inside LAN. The
VLAN ID is used in the switch where the computers connected to the particular
switch virtually knows it iis in different network so, it can’t be accessed by other
devices connected to the network, it can be accessed if same VLAN ID is used in
other switch also.

VLAN interface addition
Each interface of switch needs to add a separate of same VLAN ID according to the
requirement of user, if the user wants the ports to be accessed by all the devices, it
should use VLAN trunk or default VLAN ID for the switches.
