Custom Queue & Byte count

Hi all:

I'm seing some practices of 3.1 IPExpert book relating Qos , and I have
this question:

There is an exercise when they say to configure an interface ( see chapter
23 if you have this book) to achieve:
-IP traffic use 40% of the bandwith
-Telnet traffic use 10% of the bandwith

They did't tell you the packet size of each size. The solution provided is:

  queue-list 1 protocol ip 1
  queue-list 1 protocol ip 2 tcp telnet
  queue-list 1 default 3
  queue-list 1 queue 1 byte-count 4096
  queue-list 1 queue 2 byte-count 1024
  queue-list 1 queue 3 byte-count 5120

  As you can see, a packet size of 1024 is supposed to do this, because all
  the byte-count's are integer multiples of this value.

  The question is: if they don't specify the packet size of each traffic
  type, what must you do? I've seen other examples similar to this where a
  packet size of 1500 is supposed to calculate the byte-count?

  Anyone can clarify this, or provide a good info link, please?

  Thank you very much for your help and best regards.
