4.3 Ten thousand airline reservation stations are competing for the use of a single slotted aloha channel. The average station makes 18 requests/hour. A slot is 125 microseconds.

What is the approximate total channel load?

To compute the approximate total channel load, you must

1. Compute the number of seconds that passes per request for each terminal. Now multiple by the number of terminals to get the average request rate in requests/sec. This is the total load

Assume that one request fits into a single slot. Compute the number of slots per second you are seeing.

Recall that G is the average number of attempts per packet time. So to compute the approximate total channel load you will need to divide the total load by the number of frames per second.
