<br>
I hope this won't look like I'm invading this thread with commercial<br>
information :) I felt it relevant, though.<br>
My name is Paweł and I'm from the Border 6 company. My colleague,<br>
Mateusz, already mentioned our BGP optimization product earlier in this<br>
thread. I'd only like to add a short note about inbound traffic control,<br>
since you are wondering about it - our NSI solution is already<br>
supporting inbound optimization when needed. We are able to do automatic<br>
AS prepending for cost control and traffic balancing purpose. We can<br>
also automatically shut down the BGP session of a transit in case of<br>
detected blackout. The latter is quite important, since without it you<br>
might have one of your transits malfunctioning (BGP up, but traffic<br>
dropped), causing a general outage on your whole BGP platform, because<br>
your prefixes would still be announced via the faulty link.<br>
Do not hesitate to contact me off-list for more details (or see the<br>
earlier message from Mateusz with a link to our brochure).<br>
<br>
best regards,<br>
Pawel<br>
