Logical & Physical Diagrams and Narratives

Step 1: LOGICAL DESIGN & LOGICAL DESIGN Narrative

((MY LOGICAL DIAGRAM IS ATTATCHED BUT LACKED IN CERTAIN AREAS; Needs adjustments)Professors notes on my logical design; (Your firewall and router are not external. You have control over those devices. As such, they should be internal devices as their security and configuration is up to you. Also, unless you plan on recommending a hardware firewall, get rid of it from your design. It is essentially like having another router which is redundant. Routers essentially function as a firewall anyway and usually include dedicated firewall features. You need to include configuration information on both sides of your router and firewall if you keep it.For your internal network, rather than including configuration information on each client, simply add it to the top of the box. As long as the addresses are dynamically assigned, that should work fine and reduce redundency. You can also eliminate all the extra lines going to that box and only include one going to the box rather than the individual clients. You need to do something similar for the other two boxes as well. I would also advovate for the use if VLANs to help segment the network.))

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. The idea is that each person will post their work here in the discussion board to obtain peer feedback. Each student will make their initial post by the due date outlined in the schedule. Each student is then to provide two peer reviews to their peers, providing feedback for each item as well as overall comments. Utilizing the results from this process, each person will be able to develop a comprehensive solution by incorporating what they deem to be the most appropriate elements of various submissions into their individual project, editing as appropriate to insure a quality end product.

• 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.

STEP 2: PHYSICAL DESIGN AND PHYSICAL NARRATIVE

– Create floor plan attached and include all needed charicteristics. Please ensure colors are similar for logical and physical diagrams

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 student is to develop their organization’s physical diagram using Microsoft Visio for the Network Proposal project and include appropriate narrative. This is a “project”. So your submission is building on what you already submitted for your first DB. So, this submission should include your initial logical design as well as the new content for this submission. Simply provide a link to the same document located in your shared Office 365 folder that you created as part of HW0. The idea is that each student will post their work here such that you can get feedback from others in the class that you and your team can then use to improve your group’s submission for the final NP project.

• All diagrams, figures, tables and so on should have appropriate narrative describing in plain English what the diagram is trying to communicate
• Start with a Floor Plan which includes measurements for scale.
• Wiring should be clearly marked. Narrative should use the scale to accurately guestimate the amount of wiring necessary; Narrative should discuss the type of wiring and reasons for choice, etc.
• 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, MAC addresses, etc.)
• etc

NOTE: The above is a sample. Use the floor plan provided in the Semester Project to begin developing your Physical Diagram/Design.
