I'm trying to model ADSL access link bandwidth shaping. With a link of
18Mbps, I'm using a token bucket filter (tc + netem) to model 10Mbps,
8Mbps and 2Mbps access plans. I have a couple of questions:
- do ISPs typically use token bucket filters with large bursts to shape traffic?
- what kind of burst sizes and latencies/limits are typically used for
the filter?
Thanks in advance,
Srikanth
