Provide an example of capacity planning using linear projection.?

Question

What will be an ideal response?

Answer 1

For an example of capacity planning-using a linear projection-suppose you work for a company that allows its employees to access the Internet. Informal studies performed in the late 1990s showed that the average Internet user requires a transmission link of 50 kbps. As a precaution, let's double that figure to 100 kbps to allow room for growth. Additional studies have shown that the peak hour for Internet access is around 11:00 a.m., at which time about 40 percent of the potential users are on the system. If your system has 1000 potential users, your peak capacity would correspond to 400 concurrent users, each of whom requires a 100-kbps connection. To satisfy this demand, network capacity would need to be 40 Mbps (400 x 100 kbps). Can your local area network support this much traffic? In this example, capacity planning indicates that if your company is not willing to install communications links totaling 40 Mbps, it may have to apply restrictions on how its employees use the Internet. For example, the company may have to limit the number of simultaneous users or not give the full 100-kbps capacity to each user. Alternatively, the company can simply hope that no more than 40 percent of all its users will access the Internet at the same moment in time.?
