They might wish, after many years there has been little take up of the various systems created to do this (we've spent quite some time working on the standards). Nobody wanted to pay for it to be in handsets, other features were seen as more important uses of the space/power. The next try is LTE Broadcast http://en.wikipedia.org/wiki/EMBMS brandon

Bogons filtering

Hello, With IPv4 being almost exhausted[1] , I am curious to know how many net admins have the Bogon filtering ACLs still hanging around ? Google even gave me this expired Internet Draft [2] that seems to have been intended as a BCP. Regards, -Jay.

Mechanics of CALEA taps
by Randy Fischer 10 Jun '13

10 Jun '13

Dear nanog: Honestly, I expect replies to this question to range between zero and none, but I have to ask it. I understand the CALEA tap mechanism for most ISPs, generally, works like this: * we outsource our CALEA management to company X * we don't even know there's been a request until we've gotten a bill from X. And that's the extent of it. Well, golly Slothrop, maybe someone else has started picking up the tab. Would you even know? Is that possible? Thanks, Randy Fischer

OC3/STM-1 Line Card
by Nick Khamis 10 Jun '13

10 Jun '13

Hello Everyone, Anyone know of a way of bypassing the 90K audiocodes mediant 3000 equipped for STM-1 interface using line cards and a linux box :). What we are looking to do is replace our traditional ISDN DS3 equipped for voice using an STM-1/OC3 backbone and our own put together linux box. Again, this will be used for voice signaling... Kind Regards, Nick.

It seems to somehow be related to geo-located DNS (akamai?) since the timeouts and RSTs I see in the traffic are from IPv6 akamai servers, not facebook itself. I tried de-peering from a number of networks to try and isolate it and it was not transit-specific. I stopped questioning my network when I saw a thread on Sixxs and tunnelbroker about this very issue. Hopefully it won't persist as right now as having Facebook intermittently connect is likely hurting deployment slightly. Chris
