Re: OT:MPLS Across US

My recent experiences have been with AT&T. They provide MPLS L3 VPN
services across the USA and many many other countries, and offer a variety
of QoS options. Specifically, they offer a 4 queue and 6 queue system,
with a variety of different queueing options depending on what you want to
do. NOW...the company I implemented this for, also does business in China
and Hong Kong where AT&T could not get me a circuit.

AT&T works with China Telecom in that situation. Basically, there is an
ISP to ISP connection (redundant connections actually and you get to pick
the IP addressing on that link as it must use inter-AS MPLS option A).
That portion of it all works fine, but the QoS is where it sucks. China
Telecom in this situation only supports currently a 4 queue system. AT&T
supports either 4 or 6 ...so if you actually wanted to use 6 queues, you
are kind of stuck unless you want to do a bunch of manual tedious
remarkings. Because of this, I implemented a 4 queue system across the
board.

Make sure you are aware of all these things before you pull the trigger
