Design a compnt IP network and equipment need, and subnet ip using vlsm

The Hotwire Pty Ltd (HPL) is a consulting company that advises clients about technical
requirements and solutions options available for their networks. Clients who accept advice
from HPL use this information to decide which option they will implement in their corporate
structure. As a result HPL must always provide a costed range of options for their clients.
Currently they have a small IT retail client, Web Development Company (WDC) that is
anticipating a large expansion program over the next 5 years. This client has its head office in
the city and one branch office in Ryde. The following expansion is anticipated:
1. Additional branches at Penrith and Hornsby.
2. A greater use of mobile workers who will connect to the Ryde Branch using whatever
Internet connections are available in different locations.
3. An increased On-Line presence for retail marketing and sales, to be based at Penrith.
The client employs developers to create Web Pages and Applications, markets these to
clients’ outlets as well as selling them online. The following lists the current physical
1. The Head Office City
a. Management Team – 12 employees
b. Developers – 70 employees
c. Sales – 20 employees
Ryde Office
d. Marketing Team – 20 employees
e. Retail Sales – 10 employees
f. Online Sales Team – 8 employees
g. Dispatch and Accounts Team – 14 employees
Under the new expanded structure it is expected that both Head Office and Ryde will double
in size and employee numbers. It will therefore be necessary to rebuild the company’s
network at these two locations. In addition the following new branches are expected to have
the following structure:
1. Penrith will have a retail sales outlet with online sales support as well as an accounts
a. Retail Sales – 12 employees
31270 Networking Essentials – Case Study Spring 2013 Page 2
b. Online Sales Support – 7 employees
c. Accounts – 6 employees
2. Hornsby will have a smaller outlet for sales, with all accounts being processed by
a. Retail Sales – 8 employees
b. Online sales – 2 employees
3. Mobile Workers will be employed in other Australian cities. They will be individual
employees who are based from their home, but will be able to travel anywhere the
company requires. They are primarily technical people who will provide sales and
support in the cities where they live. This team of Teleworkers is expected to grow to
10 employees over the next 5 years.
All Internet connections will pass through the company’s portal at Ryde, where the
company’s server and Online Sales are located. From Ryde each company site will be
connected using point-to-point fibre connections providing high bandwidth across the
company’s Intranet.
Web Development Company (WDC) has provided the following Networking Plan shown in
the diagram below.
Web Development Company (WDC) Network Plan
31270 Networking Essentials – Case Study Spring 2013 Page 3
Hotwire Pty Ltd (HPL) must design the network requirements for all branches of Web
Development Company (WDC). As employees of HPL your team will be required to
develop a plan for the Company network, including all costs, for all of the following:
1. The type of media you propose to use at Head Office and at each branch. This must
be adequate to allow for the 100% expansion of the Company network at Head
Office and Ryde and must be adequate to meet the requirements at each new
branch. Your recommendations should also include provision for additional
increased bandwidth needs in the future (beyond 5 years). Whilst the actual lengths
of media chosen are not required, the cost of media chosen should be included as a
cost per metre price. Installation requirements and costs must also be considered.
You must justify your choice of media. Remember this might include copper, fibre
and wireless options within the different sites. The fibre links between each site to
Ryde will be supplied by the company’s ISP and are therefore not to be included in
the above media requirements. Alternative solutions should be considered.
2. You are required to subnet the Company’s network IPv4 Address using VLSM.
You will be required to provide summary tables with IP Address ranges for all
hosts in your network. When allocating addresses you must allow enough addresses
for the 100% expected future expansion and additional hosts at each new branch, as
well as point-to-point addresses for the mobile workforce as they will be
communicating via VPN links. Additionally, you need to allocate IP Addresses for
networked printers. You need to allow one (1) printer for each 50 employees or part
thereof for each subnet, allocating a minimum of one printer per site. The small
sites at Penrith and Hornsby will require only one (1) printer for the entire site.
Printers will have the last usable address/es within the subnet/s to which they
belong. The server, located at Ryde, will be in a separate subnet, and must be
allocated a static IP Addresses within that network. Each teleworker is considered
a point-to-point link, and so must be addressed individually.
3. IPv6 Addresses will be added now for future use. Use the table below for IPv6
4. You must detail the hardware (switches, routers) that the Web Development
Company requires. This must include full reasons for selecting particular hardware
type (model numbers), remembering that each device must be adequate for the Web
Development Company’s requirements at the location where it is placed. You must
consider potential bandwidth usage for each link when making the decisions and
include expected bandwidth for future expected expansion. Each site will require a
minimum of one router, and also a number of switches determined by your
company. The details about computers, servers and printers are not required.
5. You must justify the type of network topology you propose to use at each Web
Development Company location. A topology diagram for each location should be
included in your report.
31270 Networking Essentials – Case Study Spring 2013 Page 4
6. WDC expects to conduct a great deal of business via the Internet. Communication
on the Internet is therefore essential. Select and fully justify the type of Internet
access you propose to have for this Company. This must be scalable to allow for
future growth and needs. The Point of Presence (POP) is located at Ryde.
7. As a model for explaining your proposal to WDC, your team will build your
network using Packet Tracer 6.0.1. This model will include all IPv4 and IPv6
addresses required and use XXXX routing protocol. This working model will be
part of the delivery requirements and will support the written report.

IPv4 Addressing
The Web Development Company (WDC) has purchased the IPv4 Address ____________
(supplied by your instructor) from its ISP for addressing all hosts within their network. Using
VLSM, subnet this IPv4 Address range to provide addresses for all required hosts. This
addressing scheme should allow for the 100% growth at Head Office and Ryde, all new
branches and Teleworker addresses . Complete the table below (which shows a sample of
required subnets, but must be expanded to show them all). The IPv6 Address
2001:acad:eba1:0001::/64 has been obtained as WDC IPv6 address.
1. Apart from the IP Addresses, you are not required to supply any WAN link
information. This includes fibre cables, VPN connections, and any security issues
relating to those links.
2. All branch offices can be considered an extension of the WDC network, and so the
IPv4 Addresses allocated must be reflected in the overall addressing scheme for the
3. The only media requirements required are those internal for each site.
4. Hardware (such as routers and switches) should reflect expected usage. Therefore,
low usage environments such as those for Hornsby Branch, would require different
hardware than high usage areas, such as those of the Ryde Branch.
5. Internet Access for the entire company, the Point of Presence (POP), is through the
Ryde Branch. This connection should be sufficient for all current users, and scalable
to allow for the expected increase over the next 5 years.
6. Teleworkers will use VPN connections from a variety of sites into the Ryde Branch.
Each teleworker should be considered a point-to-point network for IPv4 Addressing
(and subnetting).

Assignment Submission
The assignment submission should take the form of a report that thoroughly details the
reasons for decisions made, as well as the actual decisions made. Alternate solutions with
appropriate costing should also be included where appropriate. You should ascertain actual
costs by searching the Internet. Provide all your costs in Australian dollars.
(Note: Many web sites are US based. Take care not to quote prices in US dollars.)
The total length of the report is 2500 words. In addition you should include a Title Page,
Index Page and a page listing all references. These additional pages are not to be included in
this word count. Be sure to number all pages in your report.
An Executive Summary is also required, and should be no more than 200 words. This is in
addition to the 2500 word report.
All information sources must be appropriately acknowledged and a full bibliography is
It is expected that this will be completely your own work. Therefore using the ‘cut
and paste’ technique is not acceptable. You should read relevant material, and then
write your report in your own words. This report must be submitted to turnitin, and so
will be checked for plagiarism. For more information refer to:
This assignment is to be done as a group of four (4) students or a group of three (3)
students. It is expected that all students will contribute equally in all aspects of this
Case Study. Each student in every group will be required to complete a feedback form
detailing each group member’s commitment, and this will be used to adjust marks for
students who do not commit themselves fully to the Case Study requirements.
Students who have difficulty working with their group must inform their instructor
immediately a problem occurs so that a resolution for the difficulty can be made. If no
such contact is made it will be assumed that no problem exists and no later student
protests will be accepted.
Much of the work can be based on research carried out on the Internet, and reading the
Cisco Online curriculum as well as the Structured Cabling Supplement found on UTS
Online, but many other sources are available. All information obtained must be fully
referenced using the Harvard method. It is expected that each student will spend
approximately 24 hours on this Case Study.
The Case Study report is due by 11.59 pm on Tuesday of week 11 (15/10/13) as a soft
31270 Networking Essentials – Case Study Spring 2013 Page 8
copy submitted to turnitin via UTS Online. Only one group member per group is to
submit the soft copy on behalf of the whole group, because multiple copies will show
100% similarity. A hard copy must also be delivered to your Instructor at the beginning
of your Wednesday (16/10/13) or Thursday (17/10/13) lab session. The Packet Tracer
file must be submitted electronically to your Instructor during the week 11 lab sessions.
Late assignments will incur a penalty of 15% per day. No assignments will be accepted
after 7 days (100% marks) as the mark for this assignment will then be zero (0). The
submission time and date will be that shown on the receipt received from your
submission to turnitin. You are strongly advised to upload your Case Study at least an
hour before the deadline as problems do sometimes occur that result in late
submissions. A time stamp of Wednesday 16/10/13 00:01 will be penalised as late.
This case study will assess the listed objectives and related graduate attributes stated in
subject outline.
It is expected that the Case Studies will be marked by week 12 (Wednesday 23rd
October or Thursday 24th October) and returned in that lab session. Appropriate
comments, where necessary, will be written on the marked Case Studies. If this
deadline is not met, marks will be posted on UTS Online against student ID numbers,
and an email will be sent to all students, with the Case Studies returned in week 13.
There is no minimum mark required for this Case Study. Students who fail to attain
50% for it will need to work harder in other assessment items to make up the deficit.
The Case Study must have a title page with the following information:
Course Name – Networking Essentials
Course Number – 31270
Case Study Title – Case Study
Case Study due date – 15th October, 2013
Word Count – Found under ‘Tools’ on the menu bar
Names – The full names of all group members
Student IDs – The UTS Student ID Numbers of all group members
DO NOT include copies of referenced material or other documents (such as pamphlets)
with this assignment. However, proper referencing of all sources is essential.
Referencing should follow the Harvard system. If you need assistance with this
contact the UTS library or refer to:
