Description

Network design is as much of an art as it is a science. One of the necessary skills as a network designer includes creating diagrams, specifically, logical, physical, and wireless diagrams. For this exercise, each individual student is to develop their organization's logical diagram (described in the case for the Network Proposal) using Microsoft Visio and develop appropriate narrative.

So, what constitutes a good quality logical diagram? Well, there are several characteristics:

  • All diagrams, figures, tables and so on should have appropriate narrative describing in plain English what the diagram is trying to communicate
  • Start the diagram itself with the cloud in the top-left (we read left to right, top to bottom)
  • Appropriate use of color (designate secured and unsecured networks; VLANs, etc.)
  • Consistent use of icons (colors, sizes, etc.)
  • Recommended configuration information (IP addresses, gateways, DNS server, etc.)
  • Logical flow of icons with limited overlapping lines (grouping appropriately, aligning, etc.)
  • etc.

As an introduction, you need to identify the current situation and the issues with the existing system that need to be addressed as well as the steps necessary to provide a solution for the issue. Now, you can begin to develop the narrative for the logical design. Why did you make some of the design choices that you made? Why are you subnetting using multiple routers? Why are you segmenting using VLANs? What is the logical topology of your network and what does that mean to a business leader/decision maker? Describe in plain English/business terms how your recommended design addresses the business needs stated in the case. Do not explain what can be seen in the diagram. The diagram can be observed and a lot of useful information comes from it. But, the diagram does not tell the reader why design choices were made. That is your job as the professional and the narrative is how you convey that information. Once complete, insert your narrative before the diagram. Tables and figures such as your diagram should never be introduced first. Rather, they should be referenced (i.e. as in "...see Figure 1: Logical Diagram) in the narrative and then introduced after the first paragraph in which they are mentioned or at the top of the next page.

NOTE: This is the first part of an assignment that continues to build. In other words, for the next assignment, you do not need to create a new document. Rather, you simply need to post the same document that have continued to build. So, treat this as a formal proposal. Include a cover page, headings, etc.

The objective of this project is for each student to individually develop and demonstrate their understanding of network analysis and design, along with their understanding of technical and managerial implications that such decisions have. The project focuses on creating an appropriate network design given the business case presented, addressing management issues, security issues, financial issues, etc. Each student is to perform as an independent contractor as a network design consultant. Each consultant needs a dossier (with photo included) that demonstrates your relevant experience, education, certification(s), etc. that make you an ideal candidate for this job. Your dossier should fit onto a single page and sell yourself to the client as THE best hire for the job. Non-relevant information, though interesting, should NOT be included. This should be located after the cover page before the table of contents of your final submission. You are to manage this as a professional project. At this point, you have either had the Project Management class, and this will be an opportunity to demonstrate some of your project management skills, or you will be taking it (as it is a required class), and you can begin learning some of those skills early. You are to create a Work Breakdown Structure that includes each task and associated sub-tasks as well as realistic estimations for days to complete. You are to include this with your initial project draft as part of the appendix with plans on updating it as necessary throughout the semester to more accurately reflect your progress. NOTE: This is not for the network design project but rather, for the semester project itself that I am wanting you to track. You have MS Project available to you through Microsoft Imagine. I also like Gantter, a cloud-based, free Project Management application. You should create the various steps necessary to complete this assignment. For more information on Gantter, see the following videos: https://youtu.be/VpKWn8Rqk40 While we are working on the project throughout the semester and getting regular feedback through the discussion boards, you should only be actively working in a single Office 365 Word Document, essentially building on the work that you have done up to that point. This file should be stored in your shared Office 365 folder created as part of HW0. You may have other working files such as Visio, MS Project, etc (all which should be kept your shared Office 365 folder) but those are support documents. Make sure everything needed to review your submission is included within your document that you are submitting and that I have the ability to edit as I shall be providing feedback through your document. Case: Ronald Chump Goes to Washington Ronald Chump has hired your firm to consult with her campaign manager to help him with his upcoming re-election. Ronald's regional campaign will be based out of Dallas, Texas where he has a home but will require a lot of assistance in order to effectively reach potential constituents across the state. Ronald’s campaign is just gearing up in this election cycle and he has recently procured office space for his main office in downtown Dallas with enough square footage to support the bulk of the paid workers on his campaign. Ronald currently has 6 full-time employees hired to his team but predicts that he will add an additional 40 full-time employees as the campaign gets under way. In addition to his full-time staff, the campaign will also utilize hundreds of volunteer workers in various positions. In addition to the office space in Dallas, Ronald's campaign manager has also located potential satellite offices in major metropolitan areas throughout the country. Each office will be staffed by a regional manager and support staff to help Ronald in his efforts. It is critical that all of the personnel in each of these offices communicate effectively with the main campaign office and work to meet the needs of the diverse constituents in different areas of the country. Currently, his campaign staff has the bare minimum of equipment and infrastructure. Most are using their personal laptops to get the campaign underway. Ronald knows that a lot will need to change. Ronald and his staff will need cutting-edge IT to help him win his re-election. His campaign will need information systems to help him cover many aspects of traditional business. Systems will need to be in place that will allow for purchasing of materials from bumper stickers to advertising space. Resources will need to be dedicated to maintaining an online presence to allow Mr. Chump to reach younger voters in Texas and beyond. Databases will need to be created to allow the campaign to manage relationships with potential donors from the initial contact stage through the acceptance and documentation of donations. Other systems that support surveys, polling, and political strategy will also need to be considered. Mr. Chump knows the importance of strong IS support in a campaign. He has set aside a considerable amount of his campaign budget for this. He would like your company to make recommendations on the best way to integrate IT into his re-election campaign. Mr. Chump’s campaign manager found an office space available in downtown Dallas to serve as campaign headquarters. It is a new construction, just nearing completion. It is ideal for setting up and installing any necessary infrastructure requirements that you might have for your information system as the installation of sheet rock, drop ceilings, and electrical outlets is not yet complete. The construction contractor has agreed to allow you access to the building before completion to install whatever you might need to meet your technology needs. Below is the floor plan for this new building. Figure 1: Ronald Chump's Facility* * Consider the average exterior door width to be 3 feet in order to determine the scale for Figure 1. You are to plan, analyze, develop, and implement an organizational network that will help Mr. Chump support his re-election goals. This includes the development of both a wired and wireless infrastructure, networking devices (routers, switches, WAPs), clients/servers, printers, etc. Assumptions: • • No existing IT exists within the building and only that adequate power and AC outlets as well as heating and cooling are installed throughout the building. You will need both secured and open wireless access For your submission, you need to clearly identify the requirements of the design, state assumptions, develop a logical, physical, and wireless design for campaign headquarters as well as a logical WAN design, develop a thorough cost/benefit analysis, and manage the project using appropriate project management tools. Security needs to be considered throughout the process from a methodically sound approach. Lastly, you need to incorporate a network management solution that will provide a high speed networking solution that can provide remote connectivity to both campaign headquarters and remote sites that will minimize costs and administrative oversight so that Mr. Chump can focus his efforts on getting re-elected. NOTE: Use Microsoft Visio to develop the logical and physical diagrams for this project. Microsoft Visio is a widely used tool for this purpose and you should be familiar with its use. You can use the business computer labs on campus, download the trial version, or use the DreamSpark subscription to obtain Microsoft Visio. NOTE: Use citations to support your assumptions for both in line and references using APA format. For example, finding appropriate payscale data, you may want to use and reference payscale.com (Links to an external site.). Make sure you cite it appropriately. NOTE: Be sure to reference “credible” electronic resources to support your responses and cite accordingly. Wikipedia may be used but should not be used without other sufficient supporting resources. NOTE: Academic dishonesty in any section of the network project will result in an automatic zero. Submit your project to the TurnItIn.com submission link and verify that your are citing appropriately. Be sure to make corrections before the final due date/time. Review the rubric to make sure you are aware of the criteria on which you are being graded. Deliverables for this submission are: • You should submit your proposal as a link to an Office 365 document, not a Google Doc, PDF, etc. The file should be named "Network Proposal" and stored in your shared Office 365 folder created as part of HW0. The idea behind this is that I should be able to "pop" into the shared folder at any time, and see the shared files. I MUST have read/write access in order to leave comments in your document. Failure to provide this access will result in a grade but with limited feedback: o Engaging cover page including your name and appropriate graphics o One page Dossier o Table of Contents (one page) o Executive Summary (one page; written last) (Links to an external site.) o Introduction o Business Case (Largely a regurgitation of the case; instill in your client that you thoroughly understand their business problem and their goal for your solution): As part of the systems analysis process, if you have questions regarding the project, be sure to ask those questions in the 'Ask your professor and/or your peers' Discussions. o Logical Design and Appropriate Narrative (Incorporate feedback from DB posts) o Physical Design and Appropriate Narrative (Incorporate feedback from DB posts) o Wireless Design and Appropriate Narrative (Incorporate feedback from DB posts) • https://youtu.be/LTC4v0-aRno ▪ There are various tools out there. One that has been used in the past is Aerohive (Links to an external site.). It can be a bit finicky, require registration, the registration expires after 30-45 days or something like that. But, it gives you the option of using Google Maps to start diagramming a building or allows you to upload an image to use. Very cool tool. o o o o o Address Security Concerns with Appropriate Narrative (Incorporate feedback from DB posts) ▪ Use Microsoft's Risk Assessment tool (MSAT) to develop your risk assessment (https://www.microsoft.com/enus/download/details.aspx?id=12273) ▪ Based on your risk assessment, develop a security matrix, clearly indicating linkages between your MSAT results, identified vulnerabilities, and your choice in countermeasures and/or; ▪ Based on your risk assessment, develop threat scenario worksheets, clearly indicating linkages between your MSAT results, identified vulnerabilities, and your choice in countermeasures.
