Exercise 5-2: Best effort and Voice traffic class

For this test we setup an IPerf stream on station 2 which emulates a 1 Mbps audio stream with packets of 250 bytes. On station 1 a continuous Best Effort stream is active that tries to maximally occupy the medium. First, station 2 will try it's stream as Best Effort, afterward the Voice traffic class is used.

Executed on the access point:

iperf -s -u -i 1 -p 5001
iperf -s -u -i 1 -p 5002

Executed on station 1:

iperf -c -u -b 50M -p 5001

Executed on station 2:

iperf -c -u -b 1M -p 5002 -l 250
after 15 seconds:
iperf -c -u -b 1M -p 5002 -l 250 -S 0xE0
