I got into a "spirited discussion" tonight about just what the upstream
effects of traffic shaping look like.
In the case in point, a private WAN with quite a few routers connects to
a number of Internet POPs. In some cases, the "leaves" are three or
four hops from the backbone source.
The central focus of the discussion was the relative harm/benefit from
putting the traffic shaper at the point where the bandwidth hits the
Internet, at one extreme, versus at the "last-hop" routers on the other.
I won't go into the details as I suspect there is probably a cut and
dried answer.
And rather than proffering my own ideas, I would rather not embarrass
myself and just ask the experts.
Thanks.
B.
