Hello from Gregg Levine usually at Jedi Knight Computers
I hate to be a nitpicker, or a piker, but what about backward 
compatibility? And what about Port Assignment? And what about Service 
Numbers? Obviously these are minor things, but probably they will turn out 
to be important later.

| 6bone Folk,

| At the recent Minneapolis IETF meetings, the three RIR registries (APNIC,
| ARIN and RIPE-NCC) had meetings with various groups about their recent
| draft proposal for policies regarding the assignment of production IPv6
| Sub-TLA address prefixes. One of the most difficult aspects of their 
policy
| (for them and for the IPv6 community) is to figure out how to go safely
| between the two extremes of either giving Sub-TLAs away too easily, or
| making it too difficult to get them.
|
| If Sub-TLAs are given away too easily, they will be encouraging non-ipv6
| providers to get theirs now, i.e., the land rush model which could easily
| fill up the TLA/Sub-TLA space with networks, sites, and organizations 
that
| simply want to make sure they have a TLA/Sub-TLA, even if they don't need
| one now or really qualify (i.e., they have no intent on putting up IPv6
| service and/or are simply not higher level transits).
|
| Alternatively, if Sub-TLAs are too hard to get, especially in the early
| days of IPv6 deployment, it will discourage providers from putting up 
IPv6
| service, may give the impression that IPv6 doesn't help the address space
| problem at all, thus greatly impeding the progress of IPv6 deployment and
| transition, and even pose a legal risk to the registries.
|
| During the meetings and discussions with the registries during the IETF
| week, the idea of potentially using the 6bone as some sort of
| prequalification for getting Sub-TLAs from the RIRs was proposed. This
| could be especially useful during the "bootstrap" phase of IPv6 
deployment
| and address assignement (say 6 months to 24 months max). This idea was 
well
| received by the RIRs, the IAB, the IPv6 co-chairs and various folk in the
| IPv6 community. Thus the idea was pursued with a first draft reviewed by
| the IAB, the RIRs and the IPv6 co-chairs. Now it is time for getting
| comments from the 6bone community, which is the purpose of this email.
|
| An overview of the idea is that a network wanting a Sub-TLA would go
| through the process of joining the 6bone to become a pTLA (for which 
rules
| and procedures are in place, and soon to be reworked based on the 6bone
| hardening effort now underway), and after spending 3 months as a pTLA 
would
| ask for a "fitness report" from the 6bone community (actually a small
| oversight group) to be made to the relevant RIR so that a Sub-TLA could 
be
| assigned (thought it will still be the RIR making the actual decision and
| assignment).
|
| Note that the RIRs will soon reissue a draft incorporating other ideas 
and
| comments from various sources, and will continue to have Sub-TLA
| prequalification criteria independent of the ideas presented here. Also
| note that the RIRs will still be the folk in charge of deciding who gets
| TLA/Sub-TLAs. Our processes, if adopted, will only be advisory to the 
RIRs.
|
| So, please review this carefully and send your comments to the full list
| above (unless you have some reason to say something in private to 
someone!).
|
|
| This will be open for discussion until 19 April '99, at which time the 
IAB,
| RIRs and IPv6 co-chairs will decide whether to move forward on an 
agreement
| about this or not, based on comments received.

| ------------------
| 6bone Prequalification for Sub-TLA Assignment - draft 2, April 4, 1999 -
| Bob Fink
|
| The following is a draft to describe how the 6bone might be used as a
| prequalification step during the "bootstrap" phase of Sub-TLA assignment 
by
| the Regional Internet Registries (RIRs):
|
| It is predicated on the following facts:
|
| F1. the 6bone community represents the world-wide IPv6 operational
| networking community as of early 1999, including all existing IPv6
| providers and users in the world, operating under the only IPv6 address
| allocation and authority in place at that time, i.e., the 3FFE::/16
| allocation to the 6bone under RFC 2471 ("IPv6 Testing Address 
Allocation")
| <ftp://ftp.isi.edu/in-notes/rfc2471.txt>.
|
| F2. the 6bone has a well defined address structure underneath the RFC 
2471
| allocation for high-level (top tier) transit service providers, know as a
| Pseudo-TLA (pTLA), that all the known top level IPv6 transit providers 
are
| part of. See <http://www.6bone.net/6bone-testv2-addr-usage.html> for
| documentation of the pTLA structure. The pTLA structure is modeled on the
| TLA structure and serves as a proving/testing ground for those 
structures.
|
| F3. the 6bone process for becoming a Pseudo-TLA (pTLA) is well defined 
and
| accepted by the 6bone community. See
| <http://www.6bone.net/6bone-routing-practice.htm> Section 7 for 
Guidelines
| for 6Bone pTLA sites. It has just been made Informational RFC 2546.
|
| F4. the 6bone community as a whole is willing to provide their knowledge,
| experience and opinions as part of a process to help "bootstrap" the
| Sub-TLA (sTLA) address allocation process for the RIRs.
|
| ===
| 6bone Prequalification for Sub-TLAs
|
| S1. the sTLA requestor (sTR) places their Sub-TLA request with the
| appropriate RIR and declares that they intend to use the 6bone
| prequalification process (6PP).
|
| S2. the sTR (and the RIR?) notifies the 6bone list of their intent to use
| the 6PP.
|
| S3. the sTR follows the published process for becoming a pTLA (This will
| change by the end of the OSLO IETF meetings as the 6bone hardening 
process
| is approved by the NGtrans 6bone community). At the present time this
| process is documented by [RFC 2546] Section 7. This process currently
| requires 2-3 months minimum, based on this current practice, from the 
time
| of first joining the 6bone as a end-site network.
|
| S4. after the sTR has been approved as a pTLA, and operating as a pTLA 
for
| 3 months with at least y customers (either lower level transits or
| end-sites) (recommend 3 customers), the pTR petitions the 6bone mailing
| list for support of its request for a Sub-TLA based on its performance as 
a
| pTLA, providing relevant proof or statement of how and/or why they 
believe
| they have met current 6bone backbone practices (currently as in RFC 
2546).
|
| S5. a 6bone steering group (consisting of 3-5 persons established by 
6bone
| participant consensus) prepares a short 6bone fitness report report (6FR)
| based on input received from 6bone participants (note this means members 
of
| pTLAs, pNLAs or end-sites organizations, not just mailing list 
subscribers)
| and factual information of compliance with established pTLA rules extant 
at
| the time (currently RFC 2546) and submits this report (the 6FR) to the
| appropriate regsitry (will need a well established contact point for the
| three IRRs).
|
| S6. if after the minimum time for the steps above, plus 1 (2?) month(s),
| the sTR may protest to the appropriate RIR of non-responsiveness and 
revert
| to another qualification process per RIR rules (unrelated to the 6PP).
|
| S7. after assignment of an sTLA to the sTR (by the RIR), the sTR may
| optionally renumber from the 6bone pTLA prefeix to the sTLA prefix, or
| continue use of their pTLA. If the pTLA space becomes over subscribed, 
the
| most likely networks to be asked to surrender their pTLA would be those
| holding production number space.
|
| ===
| Misc. Notes:
|
| N1. currently the RFC 2546 doc is being reworked under the 6bone 
hardening
| process now underway, which will almost certainly yield a stronger set of
| rules on what it takes to become a pTLA.
|
| N2. the current RFC 2546 doc does not specify a prequalification time as 
a
| pNLA or end-site 6bone site prior to requesting a pTLA, so it is
| recommended that a minimum of 2 months be specified (prior to the new 
rules
| being published after Oslo).
|
| N3. in S6. above, the total time from start of the 6PP until a protest
| could be made to the RIR, would be in the 6-8 months minimum (2-3 mos.
| while becoming a pTLA, 3 mos. while a pTLA, plus 1-2 mos.).
|
| N4. we need a way to handle existing pTLA sites that should not really 
have
| an sTLA as they are not production networks, rather they were created to
| "bootstrap" the 6bone or help a specific testing user community. This 
might
| include sites like INNER, TELEBIT, VIAGENIE, CISCO, NRL, UO, 3COM, MERIT,
| BT-LABS. Note that DIGITAL (now COMPAQ) is different in that they are
| acting as a real IPv6 exchange thus have not been included in the 
previous
| list. It is doubtful that these site would ask, but if they did it would 
be
| unlikely they could get a positive 6PP Report. So maybe the problem 
should
| be ignored and let the 6bone community police itself on this.
|
| N5. clearly this process will be none too quick between the time to get 
it
| firmed up and agreed to and the inherent time built into the process as
| described above. Thus it may get poor support if the revised RIR draft
| offers a reasonable alternative (of course that's why I noted this was a
| voluntary path for sTRs to take). On this we will have to see what the 
RIRs
| do in their next draft.
|
| N6. there may be a liability exposure of the IETF with this process, 
given
| the 6bone relationship to the IETF. This need not be covered here, but
| everyone should be aware of the issue.
|
|
| Things forgotten !!?? :-) Speak up!
