prio test results

["comp.techs" <comp.techs@xxxxxxxxxxxxx>]

Hi, below are some test results from implementing a prio qdisc 'that is also below'.
The qdisc is attacted to a vlan interface for my external network. Both tests were run
at the same time.
The links are policed at 6.0M 'by our provider'.

192.168.70.1 --> 192.168.30.1

My question is: If using a prio qdisc should'nt the iperf run with a tos of b8
have the majority of the bandwidth?

thx jason
