Hello~~~ If I use 2 token buckets to emulate TSpec's avg rate and peak rate(RFC 2212), how to set tbf2 's bucket size? If tbf2 can gather tokens , then sometimes it will generate an flow whose rate is larger than peak rate. Can I set bucket size to zero to make it a leaky bucket? flow -> tbf1 -> tbf2 -> flow tbf1 bucket rate = avg rate tbf2 bucket rate = peak rate bucket size? Jay...
