Hi all,
I am currently trying to test the schedulers available in Linux - CBQ,
FIFO, PRIO, SFQ and WRR.
My setup is simple -
Source --------- Router --------- Sink
eth0 eth1
- The links are 10 Mbit links.
- I am generating average traffic of 1Mbps at the source
- I have to throttle/rate-limit the router-sink link to 1Mbps to make it
look similar to a T1 link to the internet.
- I need a rate-limiting architecture which will allow be to test various
schedulers as well as impose a strict limit on the outgoing link.
- I hope to cause queueing due to the statistical nature of traffic
(TCP,UDP) so that instantaneous source thruput might be greater than
1Mbit/s.
I thought of using a TBF class inside a CBQ root qdisc to rate-limit
traffic, but that would drop extra traffic which would prevent queuing.
I would like ideas on how to create queuing assuming that the outgoing
link is like a T1 link. Also what kinds of traffic can i use to simulate
real life situations?
Regards,
Amit
