You question would usually include a packet size for each protocol. Here is
an example if you have a packet size for each.
DLSW gets 25% and has a 512KB packet size
Telnet gets 25% and has a 1500 KB packet size
Citrix gets 50% and has a 1500 KB packet size
To figure out byte count use the following formula.
Divide the percentage for each protocol by packet size.... You get the
following.
DLSW 25/512 = .048848
Telnet 25/1500 = .01666
Citrix 50/1500 = .03333
Divide the output of each by the smallest number.
DLSW .048848/.01666 = 2.93
Telnet .01666/.01666 = 1
Citrix .03333/.01666 = 2.0006
Round this number and multiply by byte count.
DLSW 3X512 = 1536
Telnet 1X1500 = 1500
Citrix 2X1500 = 3000
Now to verify that you are close to the proper percentages by adding all
byte counts and dividing by each one.
1536+1500+3000=6036
DLSW 1536/6036=.25473
Telnet 1500/6036=.2485
Citrix 3000/6036=.4970
If you do not round up in the earlier step, you this formula will come a
little closer to the exact numbers, but using DLSW as an example, if you
were to multiply 2.93 X 512, you actually get 1500.16 as a byte counte. If
you use 1500 as your number, you will still send 3 packets before your turn
is up which equals 1536..... That's as close as you can get!
