For that reason I'm sure there will be a small droid army of independent systems monitoring and studying every change the Global Trust Anchor makes - ready to sound the alarm. It's probably easier to keep an eye on one trust anchor than it is to monitor 5 of them. All the other arguments I've heard are in favour of a one-TA system so I won't repeat them. > > At the point in time when we understand the technical architecture > being proposed and its implications, we will formally poll the ARIN > and NANOG community on the question of whether there is support for > having an RPKI Global Trust Anchor.

At $DAYJOB I had to set our SSL VPN system to re-key via new-tunnels every 5 minutes to keep it under their threshold of what looks like seven minutes for a tcp session. After that the sessions appeared to rate shape down to 128kbps. It may also only kick in during local POP congestion. I am assuming this is DPI trying to do peer-2-peer mitigation. --- James M Keller
Re: Returned mail: see transcript for details
as it so happens, i could still use a decent contact over at AS3209. noc channels are unresponsive. even tried this one listed in radb: n...@adm.arcor.net. they are doing something really funky with their cg-nat setup for mobile subs. like, frag mapping gone wrong, therefore crazy retries or acks never received, etc. for us, it is breaking SSL.
Re: Comcast contact
If you run something like a pingplotter or MTR from pbx side towards the Remote, and do similar from remote towards the pbx side... Let it run for a bit, and compare / analyse the results.. you will spot your problem very quickly. --- We find that the IP Transit is often overloaded between Comcast networks and certain IP Transit providers. or Some common IP Transit provider have their routers overloaded thus having packet loss. We have had to some route engineering to get around these issues.

Make sure the remote phone is using a low bandwidth codec too. In a previous life changing a remote (home) user's phone from G.711 to G.729 made all the difference in the world to their call quality.

Any chance someone on this list is affiliated with Comcast who could contact me off-list?

Re: RPKI and Trust Anchor question
Barb, You've apparently forgotten ICANN's time distortion field (which they'll be inventing very shortly with the zillions of dollars they'll get from the new gTLD program). Err, yeah. 2006.

Agreed. I believe that it is necessary to do the same with respect to any global trust anchor architecture for RPKI, and believe that much of this needs to take place initially in the IETF sidr working group. The first step of that process is to have an initial draft doc for discussion (which is presently being written by the ICANN/RIR technical folks.) FYI, /John John Curran President and CEO ARIN
