Hi, all: I''m involved in the study about the QoS,but have some problems , hope someone could help me answer: 1. Why most traffic shaping implement in the egress side (Uplink) rather than the ingress side(Dnlink)?(e.g. why put the police rule on the smaller bandwidth side but not put on the larger side) 2. I can''t differ the functionalities exactly between SFQ and HTB , they''re both the queueing disciplines,HTB is used to manage bandwidth ,with the DRR disp...
