RFC 3550 has massive detail on the statistics which can be collected (bandwidth, packet size, jitter, transmission interval, packets lost, etc.) but leaves analysis and interpretation of the data to the app developer
Sender and receiver reports can be stacked into a combined report
If we combine the WFQ scheduling with the leaky bucket policing options, what happens to the delay for any class of packets?
If the class’ bucket is full, and ‘b1’ packets arrive, the rate the bucket is emptied is at least R*wi/sum(w) where R is the link rate, wi is the weight of this class, and sum(w) is the sum of all active classes’ weights
