Original document is :
The section I am concerened with is Step 7.
""If the actual bandwidth is not close enough to the desired bandwidth, multiply the original ratio of 1:11.2:1.3 by the best value, trying to get as close to three integer values as possible. Note that the multiplier you use need not be an integer. For example, if we multiply the ratio by two, we get 2:22.4:2.6. We would now send two 1086-byte packets, twenty-three 291-byte packets, and three 831-byte packets, or 2172/6693/2493, for a total of 11,358 bytes. The resulting ratio is 19/59/22 percent, which is much closer to the desired ratio that we achieved.""
In step 7:
a. where did they get number 2 from?
b. Why didn't they start with 1.5 instead? Is it a trial and error procedure?
c. If you use a non integer, how would you then proceed? You would have fractional packets that you would have to round!!!
Thanks,
Pierre-Alex
