1. Divide the percentage by bytes
- 20/1500; 30/600; 40/300
2. Normalize the numbers by dividing by the lowest number
- .013333/.013333; .05/.013333; .133333/.013333
- 1; 3.75; 10
3. Round Up! (I think you missed this step)
- 1; 4; 10
4. Multiply by bytes to convert number ratio to size
- 1*1500; 4*600; 10*300
1500; 2400; 3000
- Which is equivalent to 3000; 4800; 6000
(Debatable as to whether smaller values should be used).

Subject: how come custom queueing need to take into consideration of packet
size?
Hi Group, this is one of the questions from Netmaster labs:
Configure custom-queueing so that:
20% for ftp, packet size 1500 bytes
30% for http, packet size 600 bytes
40% for udp, packet size 300 bytes
10% for the rest
The solution is
queue-list 1 queue 1 byte-count 3000
queue-list 1 queue 2 byte-count 4800
queue-list 1 queue 3 byte-count 6000
my solution is
queue-list 1 queue 1 byte-count 3000
queue-list 1 queue 2 byte-count 4500
queue-list 1 queue 3 byte-count 6000
I don't quite understand why packet size comes into play? If the
packets are smaller, that more packets will be sent with amount of bytes
allocated?
Thanks in advance....
