Cisco 7600 vs ASR 9000
by Nick Colton 22 Sep '09

22 Sep '09

I work for a small CLEC, we have been doing FTTP for 5 years now but are getting ready to update our core network and introduce IPTV services. Cisco has been recommending the Cisco 7600 as our core router. My concern is that cisco told us that in the event of an RSP failover the 7600 could take up to 30 seconds to begin routing packets again, this seems wrong to me since my old Extreme Networks BD 6808 can do failovers and rebuild route tables in under 5 seconds but?? More recently I have been reading up on the ASR 9000 however and it appears that it would be better sized for our company than the 7600. A few questions I have for the group. 1. Has anyone used the ASR 9000 in place of a Cisco 7600? 2. Is the ASR 9000 Carrier ready? Meaning 5x9's of availability, few component failures, solid software...etc 3. Has anyone had issues where it took the 7600 30 seconds to start routing again after an RSP failover? Thanks, Nick

TDM data analyzer
by jp＠seminte.lt 22 Sep '09

22 Sep '09

Hello fellow NANOGers. Slightly offtopic, but I would greatly appreciate your suggestions. For my telecommunications engineering degree I am designing a TDM data analyzer, and I need suggestion, what you would like in an appliance like that. Right now my idea is that it should be a transparent device that plugs in between two E1/T1/J1 devices and then connect to FastEthernet for data uplink. All data traveling between two devices is sent to central server that can accept data from one or more capture devices. End user (i.e. NANOGer debugging a problem) has a program to connect to data acquisition server and can see decoded Q921/Q931 signaling data and to play-out what's happening in any one of voice channels. BERT tester and signal level indication with remote fault monitoring and logging would be included also. End user will have ability to record voice data with supplemental information too. So my question to the community is what other features you would like to see in a device? And most of all - if you had a device like that would you find it useful? All replies off list greatly appreciated. I would like to ask people to forward this email to colleagues that work with voice systems or to a voice operators group if you are a member of one. Thanks a lot, Justin ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Matt Cutts from Google has publicly stated this to not be true; if it is true and he was lying, then everyone hosted at a large provider would be penalized for doing so from an SEO perspective since the likelihood of being on a 'close' network to similar content would be high when you've got hosts running hundreds of thousands of name-based sites off one /24. Actually he stated this to not be true in response to a thread I started on this list about this subject several years ago when I was complaining about Google causing IPv4 exhaustion due to people asking hosts, with some willing, to give them a bunch of IP's on different /24's for SEO purposes when there is no technical justification for it. We've had customers leave and go elsewhere after refusing to give them IP's they didn't need because they were convinced by some SEO 'expert' that they need a bunch of doorway sites on a variety of /24's. If someone is willing to leave their host over that, there are certainly going to be hosts willing to dish up IP's for SEO reasons, and the waste of addresses continues. David

subnet aggregation script
by Ric Moseley 21 Sep '09

21 Sep '09

Does anyone know of a tool/script that can aggregate subnets feed to it via command line? Meaning if I give it multiple /30s (or any size subnet) it will scrunch them together. Example: #aggregate_subnets.script 192.168.0.0/30 192.168.0.4/30 10.0.0.16/29 10.0.0.24/29 #192.168.0.0/29 10.0.0.16/28 Thanks.

West Coast U.S. interesting outage 21 Sept. ~1105h UTC
by Aaron Hughes 21 Sep '09

21 Sep '09

All, This morning around 0405h PDT there were several odd network outages around LA where packets simply stopped forwarding in several networks. I saw no circuit drops, however, several massive traffic drops. Thus far I have heard (unconfirmed) Telia had some kind of capacity drop / equipment failure and it has been fixed. Does anyone have any details on this and/or can confirm/deny this was a Telia outage? Cheers, Aaron -- Aaron Hughes aaronh(a)bind.com +1-831-824-4161 Key fingerprint = AD 67 37 60 7D 73 C5 B7 33 18 3F 36 C3 1C C6 B8 http://www.bind.com/
