I'm running ImageStream routers for the Internet distribution side of
my network (2 edge routers, 2 core routers) and I'm extremely happy...
This is a datacenter network and my customers are happy, I guess
that's all that counts.
In my opinion, I prefer to go with a open-source based solution

For any non-trivial path, it seems to me that asymmetry in forward
and return paths is normal. Symmetrical paths are the except

You should do a PPS throughput analysis of your own to see which OS
works better on the hardware that you plan to use. Drivers, and the
susceptibility of the kernel to livelock, are where t
Wonder if it was intentional or a 'classful' issue. This is why we (Level

The /9s were stolen too, as well as a host of other prefixes. I just
listed the biggies that I was pretty sure didn't belong to 23520. No
clue if it

Check out the IAR for "Potential Prefix Hijacks" and if you're coming
to this more than 24 hours after the post, do a search on AS 23520 as
the hijacking AS.
I don't know how long the routes were announced, but they seem to be
gone now. Or maybe the IAR is horribly broken, in which case I will

Thanks to all for all the feedback!
It seems what a lot of people are saying is that it's almost acceptable
(in that, you shouldn't if you can afford other devices), given the
right time and engineering. The cost of supporting seems to be
unanimously higher then going with a specific vendor.
