Subject: [Cerowrt-devel] Is ingress QoS worth the pain?

Hi everyone,

again a bit of a basic question, but what are the advantages of doing
ingress shaping in SQM?

To me it wastes a lot of CPU cycles (decreases forwarding performance)
and you can't really "unsend" any packets from the ISP. What I mean is
in 99% of cases your internal forwarding capacity is usually (much?)
bigger than what the ISP sends to at any rate.

What do I miss here? Some effects on TCP rate-limiting?



Cheers,

Steven
