bring sense to the ietf - volunteer for nomcom

Dear Operators - Please take a moment to volunteer yourself for the next NOMCOM. There are an interesting set of IAB and IESG folks whose terms expire, and now is an opportunity to correct the historical under-representation of operators in the choice of appointees to I* bodies. It is pretty simple - check RFC 2727 and the message I attach below. Tell your friends & colleagues too. Sean. - -- Message-Id: <200008291928.PAA29406(a)ietf.org> From: "Bernard Aboba" <aboba(a)internaut.com> To: IETF-Announce: ; Subject: 3rd (and last) Call for nominations committee volunteers Date: Tue, 29 Aug 2000 15:28:10 -0400 Sender: scoya(a)cnri.reston.va.us Lines: 103 Hi - I've been selected to chair the 2000 IETF Nominations Committee, the committee that will select this year's nominees for the IAB and the IESG. The good news is that I don't have a vote. The bad news is that we need to find 10 volunteers to fill this year's NomCom. Details about the NomCom process can be found in RFC 2727. If you've already volunteered, you can check that you're on the volunteer list by looking at: http://www.drizzle.com/~aboba/internaut/nomcom2k.txt The NomCom is the IETF's way of choosing its leadership. Typically, half of the IAB and half of the IESG is selected each year. It is possible that the NomCom will have to fill more or fewer slots than this, due to the creation or elimination of positions by the IESG, resignations, transfers, etc. IESG members whose terms are up include Fred Baker, IETF Chair; Scott Bradner, Transport; Randy Bush, Operations & Management; Patrik Faltstrom, Applications; Thomas Narten, Internet; Dave Oran, Routing; and Jeff Schiller, Security. IAB members whose terms are up include: Harald Alvestrand, Ran Atkinson, Rob Austein, Steve Deering, Tony Hain and Geoff Huston. For the NomCom to work as it should, the pool from which the volunteers are chosen should be as large as possible. The more people who volunteer, the better chance we have of choosing a random yet representative cross section of the IETF population. Volunteering for the NomCom is also a good way of serving the IETF community. So please volunteer. NomCom members are barred from nomination during the year they serve, even if they later resign. Therefore being selected for the NomCom provides complete immunity against selection for the IAB or IESG during that year. People who volunteer should be sure they can the afford the time, several hours per week for the next 4-5 months. The task basically involves the following activities: - Reading candidate's statements - Participating in a weekly 2 hour conference call. - Attending the IETF meetings held during the selection process. - Doing several interviews. - Speaking to IETF participants about the candidates, the job requirements or the process. All NomCom deliberations and supporting information that relates to specific nominees, candidates, and confirmed candidates are confidential. The NomCom members will be exposed to confidential information as a result of their deliberations, their interactions with those they consult, and from those who provide requested supporting information. All members are expected to handle this information in a manner consistent with its sensitivity. To qualify as a volunteer, a person needs to have attended 2 out of the last 3 IETF meetings. Anyone who meets this requirement is invited to volunteer by emailing your name, telephone number(s), and email address to aboba(a)internaut.com no later than September 3, 2000. Please put "NOMCOM VOLUNTEER" in the subject line. Once the list closes, I'll provide the list to the IETF secretariat for them to verify the eligibility of the each of the volunteers (e.g. has attended at least 2 of the last 3 IETFs). I will also ask them to publish the list prior to verification for volunteers to confirm that I actually got their email volunteering. We will then run the selection process and announce the results the week of September 11, 2000. Ten (10) NomCom voting members will be chosen from the pool of volunteers according to the procedure described by Donald Eastlake in RFC 2777, "Publicly Verifiable Nomcom Random Selection". The source of randomness will be based on the shares traded number of 12 stocks selected by the NomCom chair. The official shares traded numbers (denoted in 000s) will be drawn from the September 8, 2000 Wall Street Journal which reports the sales figures from the previous day - September 7, 2000. If trading in any of the stocks is suspended, then the shares traded will be assumed to be 0. Please volunteer. Please convince your friends to volunteer. Thank you, Bernard Aboba <aboba(a)internaut.com> STOCKS USED IN THE NOMCOM SELECTION PROCESS: eBay, Inc. (EBAY) Merill Lynch & Company (DJM) Digex, Inc.

| Internet2 provides the same thing, only faster; I'm sorry, but parts of my network are ALREADY faster than Internet2's network by a factor of four. Other fully commercial networks are also well beyond the technology that most academics brag about. The ONLY interesting large-scale academic networking project is currently being done by CANARIE, which ironically I used to call a pretty bird with a beautiful song and no ability to fly anywhere. If you want to appreciate interesting research networking ignore both I2 and v6, check out the MANET stuff in the IETF, and try to get the folks there to think much bigger scale. Sean.

I disagree, IPv6 is already significantly being deployed in the Inernet2. So far though that is only used by University and research orgs, kinda like Arpanet was in teh begining. Significant new applications are being deployed for it specifically, and great innovations are taking place. Eventually, that will replace the Internet as we know it today, and IPv6 will be implemented, unless someone comes up with anything better, which isnt that unlikely.

There are two key problems which are preventing the widespread use of IPv6, IP Allocation, and network vendor support. Support for all hosts is actually one of the least of the problems. Think of it this way, major networks want to deploy IPv6... How do they do it? They certainly can't do it on their primary backbone links and routers, the support from vendors is simply not there. Even if there was working code, they wouldn't dare deploy it on their production network, the code is too unstable (especially IPv6 routing protocols), and they risk looking unreliable in comparison to those who don't even make the attempt to support IPv6. So what do they do? Without the network there is not the demand for high traffic IPv6, and without the demand there is little desire to build the network. Should they buy seperate routers, try desperately to make IPv6 work well on a spare 7200, and hope not to get a black eye from customers who expect the same level of routine-ness we are experienced with in IPv4? Should they provision more circuits because of this? Build a parallel network supporting IPv6, without a current customer demand? Or do they say, "we'll wait until the vendors get it right"? Even if you get past all that, there is still the very obvious fact that for certain vendors, the levels of performance we expect today are because of extensive tuning for IPv4 speed, and we know we won't be seeing this level of performance right off the bat from IPv6. And while they wait, there is no usable IPv6 infastructure, less interest and development from vendors who don't really see a "need", and less demand from users who know there is no point when they can't find a network infastructure to support them. The other problem is IP allocation. ARIN and others are used to their comfortable role as IP Nazi ("No IP for you, come back, one year!"), they have happy extortion-scheme pricing on it, and they're not about to give it up voluntarily any more then NetSol would have without being forced... If you doubt this, go look at the current policies for obtaining IPv6 space. -- Richard A Steenbergen <ras(a)e-gerbil.net> http://www.e-gerbil.net/humble PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)

ARIN Policy on IP-based Web Hosting
by sigma＠pair.com 02 Sep '00

02 Sep '00

Gentle readers who might happen to be using unique IP addresses for your Web hosting customers, or for other virtualized services such as FTP, POP3/IMAP, SSL, etc, you need to be aware of ARIN's recent policy change. Basically, they won't give you addresses anymore. They're accepting comments. A lively discussion has begun, as usual.
