Semester 2, 2015
Assessment Weighting: 20%
Due Date: Week 10, 07/10/2015
Instructions:
This is a group assignment and all students are expected to contribute evenly. A peer review form must be signed by each student indicating the contribution percentage.
This report should be written in clear English, and be submitted in electronic format and a hard copy. You are expected to use references in the normal Harvard referencing style. An AIH cover sheet should be attached confirming that the work is solely your own.
A hard copy of your assignment must be submitted by the end of the lecture in week 10.
Late submission of assessment items or deferral of examinations
An assessment item submitted after the assessment due date, without an approved extension or without approved mitigating circumstance, will be penalised. The standard penalty is the reduction of the mark allocated to the assessment item by 5% of the total mark applicable for the assessment item, for each day or part day that the item is late.
Correct referencing techniques
A key skill expected of all students is the ability to correctly reference and cite academic works or other works referred to in student assignments using Harvard style.
A failure to correctly or fully cite academic works could result in a lesser mark than may be achieved otherwise and can even result in a charge of academic misconduct. It is essential, therefore, that all students become fully familiar with the recognised methods for referencing words.
Details of the key referencing methods can be found at: www.aih.nsw.edu.au MOODLE site.
THE SCENARIO
The XYZ is a new retail company with its Head Quarters building in the city, and with branches in Strathfield, North Sydney and Parramatta. In addition there are two small home offices in Hornsby and Penrith. There are WAN connections between each site and Head Office, with all Internet access through the Head Office site.
The XYZ company is planning a restructuring of its network to allow for an expected 100% expansion over the next 5 years. Whilst the numbers of sites are expected to remain the same, the number of employees, and so end computing devices, is expected to double. However, the server farm, currently 4 servers, is expected to be adequate for the foreseeable future.
REQUIREMENTS
You must design the network requirements for the XYZ company. As the network consultant you 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. This must be adequate to allow for a 100% expansion of the company network within 5 years, and must be sufficient for all bandwidth requirements for each company site. It should also be sufficient for increased bandwidth needs in the future. Whilst the actual lengths of media chosen are not required, the cost of media chosen should be included as a cost per metre price. You must justify your choice of media. Remember this might include copper, fibre and wireless options. The serial links between each site will be supplied by the company’s ISP and are therefore not to be included in the above media requirements.
2. You are required to subnet the company’s network IP Address as appropriate. 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 of hosts for the. As well, you need to allocate one (1) printer per site. Printers will have the last usable address for the subnet to which they belong. The servers will be located in a separate subnet, and must be allocated static IP Addresses within that network. The number of servers is not expected to grow.
3. You must detail the hardware (bridges, switches, routers) that the XYZ company will require. This must include full reasons for selecting particular hardware, which must be adequate for the XYZ company requirements. Again, consideration must be made with regard to future expansion and bandwidth requirements. The details about computers, servers and printers are not required.
4. You must justify the type of network topology you propose to use at each XYZ company location. A topology diagram for each location should be included in your report.
5. Communication on the Internet is 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.
IP Addressing
The XYZcompany has purchased the IP Address 200.100.48.0/22 from its ISP for addressing all hosts within its network. Subnet this IP Address to provide addresses for all required hosts. This addressing scheme should allow for the 100% expected growth. Complete the table below and add the required WAN links.
Subnet Name Subnet
Address Subnet
Mask Host Range of Addresses Broadcast Address
Head Office
Strathfield
North Sydney
Parramatta
Hornsby
Penrith
Server Network
WAN Links
Additional Information
1. Apart from the IP Addresses, you are not required to supply any WAN link information. This included serial cables, VPN connections, or any security issues relating to those links.
2. Number of hosts required for each site are as follows:
a. Head Office 120
b. Strathfield 60
c. North Sydney 35
d. Parramatta 20
e. Hornsby 10
f. Penrith 5
3. There will be a Server Network, with 4 Servers, for the entire Company. This will be situated in a separate LAN in the Head Office building. It is expected that the 4 servers will be sufficient for the next 5 years, and so will not be subject to the 100% growth requirement.
4. All branch offices and Home Offices can be considered an extension of the Head Office network, and so the IP Addresses allocated must be reflected in the overall addressing scheme for the company. The only media requirements required are those internal for each site.
5. Hardware (such as routers and switches) should reflect expected usage. Therefore, low usage environments such as those for the Home Offices, would require different hardware than high usage areas, such as those of the Head Office.
6. Internet Access for the entire company, the Point of Presence (POP), is through the Head Office. This connection should be sufficient for all current users, and scalable to allow for the expected increase over the next 5 years.
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. You should ascertain actual costs by searching the internet. Base all your costing in Australian dollars. (Note: Take care not to quote prices in US dollars, as many web sites are US based.)
The total length of the report is 2000 - 2500 words. You should include a Title Page, Index Page, the full report and all references.
All information sources must be appropriately acknowledged and a full bibliography is required.
Note:
It is expected that this will be completely your own work. Therefore using the ‘cut and paste’ technique is not accepted. You should read relevant material, and then write your report in your own words.
GENERAL REQUIREMENTS
This assignment is to be done in group. Much of the work can be based on research carried out on the Internet. All information obtained must be fully referenced using the referencing method, as per the subject outline.
The assignment is due on Wednesday (07/10/15). Late assignments will incur a penalty of 5% per day, as per the subject outline.
This case study will assess all objectives from the course outline.
There is no minimum mark required for this Assignment. 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 – Information Systems Networking Essentials
Course Number – ISY202
Case Study Title – Assignment 1
Case Study due date – Week 10, 07 October, 2015
Word Count
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 style as per the subject outline.
