It's kind of interesting that from 2001ish to current day and there is still only a handful of service providers worldwide that seem to offer *any* kind of support for IPv6. After all the propaganda, is there actually any other major deployments in the IPv6 space? >From the ipv6.org web site, I see "Most of today's internet uses IPv4, which is now nearly twenty years old." - read as it works well! " IPv4 has been remarkably resilient in spite of its age, but it is beginning to have problems." - Really? Every network I know using IPv4 still works as designed. "Most importantly, there is a growing shortage of IPv4 addresses, which are needed by all new machines added to the Internet." - I'm sure there's a lot more ways around this - and I'm sure the NANOG archives have a lot of thought food there. "It also adds many improvements to IPv4 in areas such as routing and network autoconfiguration." - I would really love to know what these are that DHCP etc doesn't already do. I tried to check out the FAQ at http://faq.v6.wide.ad.jp/ but it wasn't reachable - maybe it needs IPv6 connectivity? As for routing 'improvements', doesn't more address space just give us more routes to handle? "IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years during a transition period." - so this 'transition period' has been, what, 7 years so far? I'm still predicting that it'll be at least another 10 years before IPv6 amounts to much... On a side note, does anyone currently have issues getting new address space where it's operationally required? I don't know anyone first hand who has yet to come across this issue... -- Steven Haigh Email: netwiz(a)crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 C:\WINDOWS C:\WINDOWS\GO C:\PC\CRAWL

VSNL CANTAT-3 Optical Submarine Cable
by Martin Hannigan 18 Dec '07

18 Dec '07

Dear Colleagues: I've had multiple conversations with operators concerning the status of CANTAT-3, a submarine cable that runs from Pennant Point , Halifax, Canada, to the area of Sylt, DE and branches to locations along the route: http://upload.wikimedia.org/wikipedia/commons/3/3b/CANTAT-3-route.png 1. Pennant Point , Nova Scotia Canada 2. Vestmannaeyjar, Iceland 3. Tjørnuvík, Faroe Islands 4. Red car, England, UK 5. Blaabjerg, Denmark 6. Sylt, Germany Does anyone have formal or published indication from VSNL that confirms a decommissioning and states an actual date? I've heard this from several highly reliable sources and I'd like to find out "when" if at all. I have checked Google. I'd be very happy to receive any information formally, off line, or otherwise and summarize back to the list. Best, Marty

Someone else mentioned "self-infliction" in this thread, and that's spot on. Over the course of the past year or more, we've seen less & less "scanning & self-propagating" malware, and more & more self-infliction, either by being duped via social engineering or just by drive-by infections/compromises. As it stands, now -- and unless the pendulum swings the other way -- the whole "...v6 address space is larger, thus it is much harder to scan and thus propagation of worms is much harder..." train of thought is completely misguided. - - ferg -----BEGIN PGP SIGNATURE----- Version: PGP Desktop 9.6.3 (Build 3017) wj8DBQFHZ+v6q1pz9mNUZTMRAviAAKC1z/Q0m1xzFmSkah5WL8xrbD/cEgCfaKgi xQHKSq8Tx8D5JEv6ObrGVoQ= =mdeP -----END PGP SIGNATURE----- -- "Fergie", a.k.a.

RE: VSNL CANTAT-3 Optical Submarine Cable
by Neil J. McRae 18 Dec '07

So in a former life I experienced first hand this cable between 97 and 99 and it had quite a few issues and outages some that lasted a significant period of time. One of which was a failure in the Iceland region caused by a boat of some description. Id need to boot up my old sparc to untar the mail backup to be sure though. Its was a great cable for cheap links for EU to US voice but for Internet the additional C.70ms from PP to NYC made it suboptimal however in the late nineties bandwidth was still relatively pricey most trafic EU to US was paid all by the EU SPs and Cantat3 was cheap and had less half circuit type issues than other TAT cables.

In January of '06 there was a major outage on Cantat-3 that took a very long time to repair. This is why most people can even recall the name. Check the nanog archives if you are interested in the discussion that took place here. There is a major fishing ground north of the cantat route off of Iceland and south of Hornsfjordur , but the cable does not run through it as far as I know, a little to East, and the "big" outage was situated in the North Sea, southwest of Bergen, Norway. I'm not sure about other outages. I have found some interesting stuff in some NOC archives though. Best, Martin

Looking for generic OID to transmit free-form text in an SNMP trap
by Frank Bulk 17 Dec '07

17 Dec '07

I'm looking to do some custom monitoring of a system and the contracted NOC only supports pings, SNMP queries, and SNMP traps. My first choice was to send an e-mail and have their system ingest it, but that's not possible, and the first two aren't an option, which means I'm looking to send them SNMP traps. What OID should/do I use for sending traps with free-form text? Do I just use sysDescr? Or is there another OID that's recommended? Regards, Frank

Somewhat bizarre scenario... (Fiber distance)
by Deepak Jain 16 Dec '07

16 Dec '07

Given this 40G/100G topic, I figured I'd bring this up given the topics. I've got a link that is testing out at 29.5db loss @ 1550. Its 107km. I seem to remember a few good solutions for 1Gb/s or 2.5Gb/s that can handle a link like this, but its been a while and I can't seem to remember. I can put a regen in there if I have to, but that or an EDFA both seem like ugly solutions since I just need 1 wave. Shoot me a few suggestions? Thanks in advance, Deepak

IEEE 40GE & 100GE
by Bora Akyol 14 Dec '07

14 Dec '07

IEEE is seeking feedback from network operators etc on the reach requirements for 40GE & 100GE. If you have direct feedback to give, please contact Chris Cole directly (email address below). This is very important as it will directly impact how much you pay for those soon to be cherished 40 & 100 GE hardware in the future. I believe information on how many patch panel connections you expect the links to go through is also highly valued.

One of my motivations for working on the proposal was informal input from a number of 100GE end users that >90% of their data center and short interconnect needs would be met by a reach objective less then 4km (versus 10km.) With such a reach distribution, a 4km or less optimized reach objective would result in overall cost savings. As part of the HSSG effort to review this proposal, numerous requests, both informal as well as from the HSSG chair and Reach Ad Hoc chair, have been made for contributions to quantify the 10km and under reach distribution. While the optics vendors as suppliers can accurately represent the relative costs of optics alternatives, they can not represent end user requirements. To date, we have seen no end user presentation or data supporting changing the 10km reach objective to 4km or less. Unless such contributions are forthcoming, it is likely that there will be no motivation to make the change. This sentiment can be seen in the 12/7 Reach Ad Hoc conference call minutes. I would encourage any HSSG participant that views their volume 100GE SMF needs as better met by a 4km or shorter reach objective to make a contribution containing reach distribution data in support of this position. Otherwise we will move forward with the existing approved objectives.
