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)

The original cable will work with the new network. There is a problem tho with the current cabling because cables shouldn’t be lying on the floor. These need to be reran in the false ceiling and be plenum rated.

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)

Fiber always needs to be terminated to prevent damage to the cable ends. Also fiber is relatively double the price or more of utp.

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)

Yes an access layer is needed. Pretty much the lower end switches and wireless access points would be the devices operating at this layer. The access layer also provides better reliability and security.

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)

Yes, this network would need a distribution layer. The distribution layer applies policies and rules and the access and distribution layers cannot be combined. The distribution layer connects servers and would consists of a switch and servers.

6. Does this network...
