NETWORKING REPORT PAPER

University of Technology Sydney Faculty of Information Technology 48720 - Networking Essentials Case Study – Spring Semester, 2013 THE SCENARIO 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 structure: 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 department: a. Retail Sales - 12 employees 48720 Network Fundamentals – Case Study Spring 2013 Page 1 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 Penrith. 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 48720 Network Fundamentals – Case Study Spring 2013 Page 2 REQUIREMENTS 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 addresses. 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. 48720 Network Fundamentals – Case Study Spring 2013 Page 3 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 EIGRP Routing protocol for IPv4 only at this stage. This working model will be part of the delivery requirements and will support the written report.

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. Subnet Name Subnet Subnet Host Range of Addresses Broadcast Address Address Mask in / format Head Office City Management Head Office City Developers Head Office City Sales Ryde Marketing Ryde Retail Sales Ryde Online Sales Ryde Dispatch ......... ......... ........... More .... ........... ............. .............. 48720 Network Fundamentals – Case Study Spring 2013 Page 5 Additional Information 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 company. 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). 48720 Network Fundamentals – Case Study Spring 2013 Page 6 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 required. Note: 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: wiki.it.uts.edu.au/start/Academic_Integrity www.gsu.uts.edu.au/rules/16-2.html GENERAL REQUIREMENTS 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 48720 Network Fundamentals – Case Study Spring 2013 Page 7 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.
