CAC NETWORK PROPOSAL
Executive Summary
Before purchasing any networking equipment or even deciding any hardware platform that
should be implemented it is very essential to have a clear knowledge of the organization problem. This is
a network proposal for a small marketing firm by the name Colour Ability Corporation. The organization
is interested in upgrading its network system. Currently, the organization is operating from level 10 and
11 in Brisbane CBD. The organization has four section which are marketing, design, HR accounting, and
photography. The current network structure requires several upgrades in hardware so as to address
incompatibilities and older technologies. This will result to high-speed network, a more reliable network,
and easy to maintain the network. In addition to updating the current network, this proposal will outline
some of the network configuration that ought to be done. If CAC implements these changes it will
provide a more reliable and secure network. Along with new network hardware and new network
configuration, this network proposal will open the door for CAC to explore the emerging network
technologies. In addition, this solution will meet the current needs of the organization. The total
estimated cost for the project will be under $400,000.

CAC NETWORK PROPOSAL
Part One: Gather Requirements
CAC‘s needs
There two major requirements for the CAC’s network. First, the organization’s network is to be
upgraded to accommodate the emerging technologies. The network also needs to be simple, secure and
scalable. The organization employees need access to emails. Currently, the service is provided by the
organization ISP. The organization desire to set up an email address for all organizational employees.
CAC managers require to share files between themselves. The organization also need a wireless internet
access which ought to be made available in all the departments
Technical goals
One of the technical goal expected by CAC is to improve network capacity and Speed, improve
network security by replacing hubs with a manageable switch which provide the ability to monitor the
organization LAN and giving a greater control over how organization data travels over the network.

Activity 2
Small organizations such as CAC can use brother type of printer for printing black and white
copies. This printer prints 24 to 27 pages per minute with a print rate of around 52 pages per minute.
For color printing the organization needs to go for copies for Epson 850 series which is said to print 20
copies per minute. Epson 850 series is all in one since the organization can use it to photocopy, print and
scan copies.
Activity 3
Physical Network design
Figure 1 shows the physical topology design. The diagram demonstrates the physical design
implementation that CAC need to implement. The diagram also illustrates the main points of a network
upgrade. The points of an upgrade as shown by the diagram are cable installation, location, and devices.
As indicated by the diagram floor one which is the ground floor contains the mainframe and the
organizational server. As indicated by the diagram the mainframe connects the organization servers and
the organization switches.

Proposed network topology
From the collected requirements, it is evident that the organization client base is growing at a
high rate. For the organization to achieve its mission and goals it needs to utilize a hierarchical network
topology. This type of topology aims at making an organization network modular, manageable, resilient
and efficient.
The hierarchical network topology is divided into three tiers which are access, core, and
distribution layer. The topology allows organization network administrators to specify the correct
software and hardware for the entire organizational network (Kurose & Ross, 2016, p. 34). The topology
diagram is as shown in the figure below. The diagram was developed using Netsim.

Activity 7
CAC’s Logical design
So as to meet CAC’s both technical and design goals, the organization needs to apply Cisco SAFE
architecture when design network design. The main goal is to provide the very best practice's
information when implementing secure networks. The SAFE architecture usually uses a modular
approach which allows flexibility. It also facilitates troubleshooting and implementation. Cisco SAFE
architecture utilizes defense-in-depth approach where multiple layers of protection are strategically
located throughout the organization network. Cisco logical topology ought to be divided into three main
functional areas which are enterprise campus, service provider edge and enterprise edge. Each of these
functional areas contains network modules (Green, 2010, p. 67)
Table 6: List of Hardware device required
IP Design strategy
Different Internet
Protocols have been created aiming at supporting communication between user computers. For CAC
case, I would propose the use of distance victor protocols and link state protocols. The organization ISP
have given CAC class C type of IP address. The Brisbane Suburb 192.168.0.0/24. The number of servers
located in this location are two. Table 6 below shows IPV4 notation for the organization. Calculation is
found in the appendix

Activity 8
Public IP address assigned to computers so as to allow direct access over the internet. Private IP
address is an address given by InterNIC to organizations to create their own network. CAC can use a
combination of these two to address the concern of vulnerability. The organization can use private IP
address so that only the organization employees can access files and resources provided by the
organization. The organization can use public IP address to address the issue of reflection attack.
Security plan
The organization ought to use password protection mechanism which ought to be long and
memorable by the organization employees. The passwords also ought not to have any relationship and
should be changed regularly. All organization data should be treated as confidential

Future plans
Due to budget consideration, the current physical design as shown in figure one is designed
using CAT 5e type of cabling. The current cabling might not facilitate high speed. The organization need
to plan for Passive Optical type of cabling. This is a type of cabling which uses optical splitters so as to
divide a single optical connection aiming at serving multiple end points. This means that the
organization will in future change the physical design to the one shown in figure three.
Figure 3: Future Physical Design
Recommendations and conclusion
The main goal for this project proposal is to upgrade the existing network of CAC. As part of the
upgrade the inclusion of physical design and the network topology is shown in the diagram which
includes the modification. A security evaluation have also been down in accordance to the laid
standards. Implementation of each upgrade will incur cost which is shown in a table. For the WAN
design, I would propose the organization to use metro Ethernet WAN technology. This is because it is
scalable, enables new applications and it is reachable. It also scales very well with the current standards
100Gps and 40 Gps. CAC need to go for optus ISP as the organization since it has high speed internet
connection. Lastly, the implementation of this new network upgrade will provide the much needed
benefit of improving security and fault tolerance and achieve organizational goal of modernizing its
technological resources.
