You will create a design for an Ethernet network connecting four buildings in an industrial park. Hand in a picture showing your network. There will be a core switch in each building.

Building A is the headquarters building.

Building B is 85 meters south and 90 meters east of the headquarters building. A line will run directly from Building A to Building B. Building C is 150 meters south of the headquarters building. A line will run directly from Building A to Building C.

Building D is 60 meters west of Building C. A line will run directly from Building C to Building D.

Computers in Building A need to communicate with computers in Building B at 600 Mbps.

Computers in Building A need to be able to communicate with computers in Building C at 1 Gbps.

Computers in Building A must communicate with computers in Building D at 500 Mbps.

Computers in Building C must communicate with computers in Building D at 750 Mbps.

Draw a picture of the situation.
b) Determine the traffic volume on each transmission line. Explain your answers.

First, show all of the traffic between pairs of sites:

Second, add up the traffic for each line.

c) Determine what standard to use for each transmission line. Explain your answers.

If the distance is more than 100 meters, use fiber; if it is 100 meters or less, select UTP.

Then, select the lowest-speed standard (including bonding) sufficient to handle the traffic.
