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)

No, this is CM rated cable, which may not be installed in the plenum space. CMP rated cable is needed.

The new cable should be

solid copper, 24 AWG, 100 balanced twisted-pair (UTP) Category 5e cables with four individually twisted-pairs, which meet or exceed the mechanical and transmission performance specifications in ANSI/TIA/EIA-568-C.2 up to 100 MHz for installation in a plenum space;

or

solid copper, 22 AWG to 24 AWG, 100 balanced twisted-pair (UTP) Category 6 cables with four individually twisted-pairs, which meet or exceed the mechanical and transmission performance specifications in ANSI/TIA/EIA-568-C.2 up to 250 MHz for installation in a plenum space.

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)

The FOLS model will show that the cost of installed fiber optic cable is about the same as copper cable. What it omits, as does the common argument for fiber to the desktop, is the increased port cost in the work and in the LAN room switch for the fiber electronics.

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. Every network must at least have an access layer.

This diagram would be the same as the

NETW410, Professor’s Name Current Date Lab 7: Traffic Modeling Lab Report 1. Capture a screen shot of the results screen and paste it into your answer sheet. (7 points) 2. What do the stats show about the traffic entering the cloud? (7 points) It show that it have a high starting packet send to each other to establish communication. 3. Paste a shot of this screen into your worksheet. (7 points) 4. What do you observe about the packet delay related to the ToS we assigned? (7 points) That they have multiple different delays in the three interface queuing. The three could be use depend on the need. 5. Why does this simulation run so much quicker than the first one? (7 points) Because its only tracking the background traffic so it make it a little bit faster. 6. What do you observe about the queuing delays in both scenarios? (7 points) They both average out to be the same kind of startup. Although the background seem to have a smaller delay at the startup compare to the other one. 7. The first panel compares the queuing delays between the three scenarios. Paste a shot of this panel in your answer sheet. (7 points) 8. How do you compare these...

Please use the template starting on Page 2 and submit it to the Week 6 iLab Dropbox by the due date. Have fun while learning. Your Name: Sheryl Livingstone NETW410 August 14, 2013 Lab 6: Routing Protocol Selection Lab Report 1. Complete this table on routing protocols. However, many rows are needed for the routing protocol names. (10 points) Interior | Exterior | Distance Vector | Link State | Path Vector | Standard | Proprietary | Standard | Proprietary | Standard | RIP | EIGRP | OSPF | BGP | | 2. Should the individual buildings be connected to the Administration Building at Layer 2 or Layer 3? (10 points) The individual building should be connected to the Administration building at layer 3 because each building has their own subnets in the new IP scheme. 3. If the individual buildings should be connected to the Administration Building at Layer 3, which routing protocol or protocols should be used? (10 points) When selecting a routing protocol, one important criterion is how quickly the protocol adapts to changes in the network and resource allocation. EIGRP is a distance vector protocol and would be a good routing protocol to use because the network devices are Cisco based. EIGRP is fast, consumes little resources, supports VLSM, and scales well. EIGRP only works with Cisco...

...NETW410 Week 2 Lab Report To complete the Week 2 Lab Report, answer the questions below concerning the Network Design Lab Scenario found in Doc Sharing. Please use the template starting on Page 2, and submit it to the Week 2 iLab Dropbox by the due date. Have fun while learning. Your Name Christopher White NETW410, Professor’s Name Current Date Lab 2: Application of the Top-Down Network Design Methodology Lab Report 1. What are the business goals? (10 points) Redundancy is not required but it is highly recommended to reduce any data loss so the network automatically uses a secondary path if one goes down. The redundancy would be located in layer 3. 2. What are the business constraints? (10 points) The school is utilizing its revenue from property taxes and bonds that must deliver the required improvements but with a very strict budget, suggesting that affordability is more important than the best technical solution. 3. What are the technical goals? (10 points) Improve network performance by increasing the amount of users that can access the network and speed, making the network fast as possible is key to a network administrator. 4. What are the technical constraints? (10 points) The existing equipment such as the CAT5 cable should be replace with CAT6 at every drop and Fiber Optics should replace each uplink at the core. The campus should replace or upgrade its existing ISP or service so that its bandwidth is consist with campus needs for...
