inauguration streams review

Thu Jan 22 14:08:30 UTC 2009

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.

Thanks,
Adam

COWs are more or less full sites - so standard N concurrent voice
calls per carrier (check out the CDMA standard if you're really
interested), times the number of carriers. 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.
