Re: inauguration streams review

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.

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.

Just curious on that note with COW .. did you have much security related
problems setting up stuff nearby?

How many simultaneous connections can each COW handle? What kind of
connections do they have?

I can't comment on revenue-generation, though access as a whole was

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.
