you be running any multicast applications on these links? Are they
real-time video or data feeds? If so I’d steer clear of any MPLS
based solutions and stick with something that gives you a deterministic path.

I’d stay away from Radianz and YIPES as I’ve had bad experiences
with them over the past year. They have a significant amount of outages
and most go unexplained.<o:p></o:p></span></p>

have a global network with Global Crossing now and they average about 2-3 small
outages (less than 5 minutes) per week but their NOC engineers seem to be helpful
and respond quickly with RFOs. Proper backup paths prevent it causing
much of an issue.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>All,<br>
<br>
I am currently in the process of evaluating carriers for future expansion into
international regions, primarily Asia, Europe and South America.<br>
<br>
I am comfortable with AT&T and Verizon however I would like to make sure I
include all the major players and would like your direct feedback and
commentary in regards to any of them. <br>
<br>
These are the key areas I am concerned with.<br>
<br>
Support<br>
Reliability<br>
Flexibility<br>
Complexity<br>
Coverage<br>
<br>
I am looking at two deployment options as well if anyone would like to comment.<br>
<br>
1) A single carrier for global connectivity to all sites (mpls etc)<br>
<br>
2) A single carrier for global regional connectivity, and in country/regional
carriers for all local offices that funnel back to regional aggregation points.
<br>
<br>
Any insight would be greatly appreciated.<br>
<br>
Thanks, Daniel<o:p></o:p></p>
