IPv6 Space Management. Tracking, not Allocating
by chip 17 Nov '10

17 Nov '10

There's been lots of discussion on how we should allocate space to various bits of the network. What I haven't yet seen is how people are tracking these allocations. Is everyone using one of the two or three commercial applications or some OSS solution or a few large(ish) text files? Anyone have any recommendations or feedback? Thanks! --chip -- Just my $.02, your mileage may vary, batteries not included, etc....

OT: VM slicing and dicing
by Brandon Kim 16 Nov '10

16 Nov '10

Hey gents: As always I value your input. Best resource on the planet! =) I'm hoping this isn't too off-topic if so please respond to me offline if so. I figured since most of everyone here are operators working in a datacenter, you may or may not have experience with virtualization software that allows you to configure VM's on the fly. I'm not looking for companies that offer this service, but the actual software engines that allow you to create VM's on the fly. So a customer goes to your website and says I want Win2008 with 8gigs of RAM and 120gigs of HDD. Just like custom configuring a new PC. Does anyone here have experience or knowledge of companies that offer this type of software engine? Thanks in advance! Brandon

Low end, cool CPE.
by Leo Bicknell 16 Nov '10

16 Nov '10

I've run into a number of low end CPE situations lately where I haven't found anything that does what I want, but I have to believe it is out there. I'm hoping NANOG can help. Basically think about a sophisticated home user, or a 1-5 person small office. Think DSL, Cable Modem, maybe Cell Card or ISDN as backups. Looking for an "appliance", very much fire and forget. I probably won't get all the features that I want, but in no particular order: - Able to load balance over 2 links (probably via NAT). - IPv6 support, native or tunnel to tunnelbroker.net type thing. - Able to deal with "backup" connectivity, eg. Cell Cards which you only want to use if the primary is down. - User friendly features, e.g. UPNP, NAT-PMP, etc. - Good manageability. ssh to a cli would be a huge bonus, at least the ability to backup a config. - Able to handle decent througput, probably 20Mbps/sec min, 50 would be nice. _ Nice firewall features. - IDS features are cool. WiFi is not strictly required, but would be cool. Things like "guest" WiFi would be an added bonus. Something a NANOGer might want at home would be a good baseline. I realize the exact product may differ depending on DSL/Cable/Cell/ISDN, that's ok, let's get some various good solutions going here. What is the state of the art, and who has it? -- Leo Bicknell - bicknell(a)ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/

Current trends in capacity planning and oversubscription
by Sean Donelan 16 Nov '10

16 Nov '10

While the answer is always it depends, I was wondering what the current rules of thumb university network engineers are using for capacity planning and oversubscription for resnets and admin networks? For K-12, SETDA (http://www.setda.org/web/guest/2020/broadband) is recommending: - An external Internet connection to the Internet Service Provider of at least 100 Mbps per 1,000 students/staff - Internal wide area network connections from the district to each school and between schools of at least 1 Gbps per 1,000 students/staff How does that compare with university and enterprise network rules of thumb?
