6. Network architecture design, including network traffic demand analysis (traffic type, volume, and pattern), performance criteria, and logical/physical topology designs. Key diagrams must be included, showing the network layout at different levels of details. For example, if part of your solution is to use WLAN, you must decide the number of APs needed, their placement, and how they are to be physically wired into the backbone network (Note: You must provide support/justification for the specific design decisions you made)
