Khurram,
IMO the first thing to consider is the bandwidth of the circuit. Next
decide how long you are willing (or allowed) to wait until a particular
queue can transmit.
For example:
assume that you have a 256kbps circuit
this means that it can transmit 32,000 Bps
If you allocate the following byte limits for your desired protocols:
Atalk 1,500B
ipx, 3,000B
ip 3,000B
DLSW 7,500B
Once the 3,000B of IP traffic is sent the interface can send up to 12,000B
from the other queues. It will take (12000B/32000Bps) or 0.375 seconds to
transmit those 12,000B.
It is possible then that you would have to wait 375ms between IP
transmissions. If there are multiple IP traffic flows sending more than
3000 IP bytes, then the wait will be multiples of the 375ms. This might
have a very negative impact.
Hope this helps.
David Russell
