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?
