Background The IT team at Game Technology is working on an overall architecture for the new C3 system.
They solicited RFPs from several hardware vendors, and decided to work with Network
Illusions, a well-known local firm. Your job is to help analyze the server test results, and to draw network diagrams when requested.

The Network Illusions sales rep recommended a Model DX server for the C3 network, and
submitted the following data, which shows projected network response times for various
numbers of Game Technology users:System Architecture Essay Paper.
Practice Tasks Task 1. Using the data provided, create an XY chart that shows Response Time on the Y
(vertical) axis and Number of Users on the X (horizontal) axis. You learned about XY
charts in Chapter 2 of your textbook. Describe the results and your interpretation of the data.
Task 2. Draw a bus network with a server, six workstations, a printer, a scanner, and a wireless access point (WAP). Also, determine how many separate data paths are needed in a mesh network with four nodes. Five nodes?
Challenge Tasks After you complete the Practice Tasks, you learn about new developments at Game Technology. System Architecture Essay Paper.
Although the spec was for a Model XP server, Network Illusions delivered a newer model, called
the DX+. The vendor sales rep said that performance would be the same or better, but the IT
team decided to run a series of response time tests. The results are as follows:
Critical Thinking Challenge: Tasks Page
Projected Data: Server Model DX Number of Users
10 20 30 40 50
Response Time (sec) .01 .015 .02 .025 .03
Task 1. Use the actual test data to create another XY chart, similar to the first one. Describe the results and your interpretation of the data.
Task 2. Draw the same network as a star topology with a central switch. Also determine how many separate data paths are needed in a mesh network that has six nodes.
Projected Data: Server Model DX + Number of Users
10 20 30 40 50
Response Time (sec) .01 .015 .02 .03 .05

Projected Data: Server Model DX Number of Users
10 20 30 40 50
Response Time (sec) .01 .015 .02 .025 .03
When the projected data on Server Model DX is plotted, it reveals a linear relationship
where the response time closely correlates to the number of users. As the number of
users grows, the response time increases proportionately. Given this relationship, we
project that the server offers stable and predictable performance across the range of users specified. System Architecture Essay Paper.
Further analysis would be required to determine at what point, if any, this model’s
performance changes from a predictable linear relationship, to something else. This
point is sometimes referred to as the “knee” in the curve. For example, at a certain
point, the response time could begin to climb exponentially.
Task 2. Draw a bus network with a server, six workstations, a printer, a scanner, and a wireless access point (WAP). Also, determine how many separate data paths are needed in a
mesh network with four nodes. Five nodes?
To determine the number of paths, you can just draw a sketch and count the paths. This works with relatively small numbers, but not so well if there are dozens, or hundreds of nodes. For example, in Figure 10-28 on page 428, there are five nodes, including the server, and a total of ten data paths.

If you are math-oriented, you can use a formula to determine the number of data paths.
This formula is commonly used to analyze permutations and combinations of values.
Here’s how it works: Assume that the number of nodes is represented by “N.”
The formula for the number of data paths is:
N * (N-1)
2
Therefore, with four nodes, we have
4 * (4-1)
