Hi, quick question ...Most people here said they saw most of the inauguration traffic on TCP1935 to Limelight and UDP8247 to CNN. However, we were seeing it simply as "http" traffic (i.e. port 80), which made it very difficult to manage. Our inbound bandwidth was effectively maxed out for about 6 hours.
I wonder what the discrepancy is between my experience and yours ... maybe the glass through which I am peering? We're analyzing / controlling WAN traffic with Exindas.

They can do 850+PCS all carrier if configured that way. If we can grab fiber from a nearby building that's best (hence why this takes so long to plan), however a lot of time we rely on OC3 microwave backhaul. I wasn't involved with the DC guys as I'm in Boston so I don't know specifics of this event. Re: security, I don't know since I wasn't involved though since all the planning started so far back I doubt there was much issue. -Jack Carrozzo On Wed, Jan 21, 2009 at 1:54 PM, Paul Stewart <pstewart () nexicomgroup net> wrote:
Just curious on that note with COW .. did you have much security related problems setting up stuff nearby? -----Original Message----- From: Mike Lyon [mailto:mike.lyon () gmail com] Sent: Wednesday, January 21, 2009 1:52 PM To: Jack Carrozzo Cc: nanog () nanog org Subject: Re: inauguration streams review How many simultaneous connections can each COW handle?

We hardly had any voice IAs (Ineffective Attempts, or 'Busy' messages). Since data can be queued, the only thing that would cause data IAs are bad RF conditions - we had a TON of 'cell on wheels' in the area for the event so we had enough carrier space to cover it. In-network data response times were hardly affected, with switch loads well below 50%. In-network SMS were still getting to their destinations in under 5 seconds for the most part.... I don't have any numbers on MMS or mobile IP data at the moment, though I would have heard if something horrible had happened. I'm told that the out-of-network SMS queue was piling pretty high at one point, to delivery times up to an hour, though they all still got there. We can't control other network's switches obviously. This isn't trying to sound like an advertisement - *I'm* not affected either way if people sign up with us as I'm not in sales, however from my point of view it looks like we had the most solid network... Our guys were planning and setting things up since June.
