I=92m going to post these questions separately because they=92ll = each generate their own threads of conversation. QUESTION #1: How does SQM shape the ingress?=20 I know that fq_codel can shape the egress traffic by discarding traffic = for an individual flow that has dwelt in its queue for too long (greater = than the target). Other queue disciplines use other metrics for shaping = the outbound traffic.=20 But how does CeroWrt shape the inbound traffic? (I have a sense that the = simple.qos and simplest.qos scripts are involved, but I=92m not sure of = anything beyond that.)
