Lab 3: Designing the Infrastructure for the Network

Lab Report

1. Draw a diagram of the new network. (10 points)

2. Will the current horizontal cabling suffice for the new network? If it will not, what type of cable should be used for the horizontal cabling? Provide detailed specifications for this cable. (10 points)Yes the horizontal cabling will suffice but issues with the current cabling would be present and there shouldn’t be any cables lying around all over the floor. The cables should be secure and not present or visible in any walking paths, which is a hazard. Horizontal cables need to be run above a false ceiling and plenum rated, which they currently are.

3. Should fiber optic horizontal cabling be installed but not terminated as future proofing for a future higher-speed network? What is the cost difference between copper UTP cable and fiber optic cable? Use this model to compute the relative cost—http://www.fols.org/cost_model/. (10 points No, whenever using any type of fiber optic cable, they would always need to be terminated. The termination provides the connection from the cable to a patch panel. The Fiber cables are almost double the cost of UTP cabling so that is not a good idea to purchase them.

4. Does this network require an access layer? What devices would operate at the access layer? Draw a diagram of these devices at the access layer. Label all of the devices. (10 points)

5. Does this network require a distribution layer? What devices would operate at the distribution layer? What would these devices be responsible for? Could the access and distribution layer be combined into a single layer? Draw a diagram of these devices at the distribution layer. Label all of the devices. (10 points)

6. Does this network need a core layer? What devices would operate at the core layer? (10 points) This network would need a core layer because high-speed, highly-redundant forwarding services are needed to move packets of information fast...
