LARTC - Oct 2005 - shape downstream of a ppp link

Hi,

is it anyhow possible to tell the other end of the ppp link how he should
queue the packages? I have a ppp link to my isp and would like to control
the order of packages send to me. I would like to give uucp a lower
priority than http. Is this possible? Has ppp any special features to
control such things?

Bye, Jörg.

I would say no. You could only shape (= drop) some of the incoming packets,
and hope that the sender will slow down on this, because he doesn''t
receive
ACK for the dropped packets. This you can do with the normal tc methods.

Only by making a phone call and threatening the ISP directly... ;-)

It''s possible, although there is not really a nice solution for it. I
do
this kind of "prioritizing" by shaping packets that the router can
send to
the machines in my LAN, which basically reduces to "drop anything that 
comes in too fast", in your case "drop uucp packets if they come in
too
fast". Not really nice since packets have to be re-sent, but for me this 
is still better than letting one file transfer hog the whole line forever 
when I need bandwidth for interactive sessions.
