Just dropping a note that there is a fiber cut in the SF area (I have a metro line down). AboveNet is reporting issues and I've heard unconfirmed reports that ATT and VZW are affected as well. Rgs, craig

Additional news stories reporting second fiber cut on Sprint fiber in San Carlos, between San Francisco and San Jose, the SF Gate article above was updated at 12:20pm with that information. San Jose cut at around 1:30am, San Carlos around 3:30am. -george

My (user only) experience is that cellular data service doesn't handle long sessions well.

This seems to be due to the same fiber cut when following local news and scanner frequencies. -andreas -- Andreas Ott K6OTT andreas(a)naund.org

options for full routing table in 1 year?
by Jo Rhett 09 Apr '09

09 Apr '09

I was chatting with someone the other day and we were trying to build a complete list of all units which can handle full routing tables 1 year from now, assuming current 4k/month growth (nevermind de- aggregation) Juniper M/T-series units could handle 600k before, now 1mil with I- chip upgrade? Juniper MX-series units are always 1mil Cisco 6500/7600 with SUP720-3BXL handles 1mil routes Force10 E300/600/1200 with dual-cam line cards handle 512k routes Force10 E600/1200 with Exascale (quad-cam) line cards handle 1mil routes Is there anything I'm forgetting here? And if you already have one of these units, the upgrades are: Juniper M-series units can replace the FPIC card to get new I-chip? ...if I understand it, no other cards need replaced Cisco 6500/7600 you replace SUP32 or SUP720 with SUP720-3BXL ...if I understand it, no other cards need replaced? (note that this disagrees with my understanding of how their FIB/CEF works so I'm curious about this) Force10 you replace every single line card, since the entire chassis is limited to the smallest CAM size available. -- Jo Rhett Net Consonance : consonant endings by net philanthropy, open source and other randomness
