Re: [BEHAVE] Prioritization of the translation cases

[Dave Thaler <[e-mail]>]

The doodle questions were tailored to
   a) End-users (or anyone really) already using NAT-PT
   b) Implementers
   c) Network admins

So far 7 people have responded (most with multiple roles each):

1. An IPv6 network to IPv4 Internet
   a. 2 using NAT-PT
   b. 4 implementing
   c. 3 deploying
2. IPv6 Internet to an IPv4 network
   a. 3 using NAT-PT
   b. 4 implementing
   c. 4 deploying
3. An IPv4 network to IPv6 Internet
   a. 1 using NAT-PT
   b. 1 implementing
   c. 0 deploying
4. IPv4 Internet to an IPv6 network
   a. 1 using NAT-PT
   b. 5 implementing
   c. 5 deploying
5. IPv6 to IPv4 within the same organization
   a. 3 using NAT-PT
   b. 3 implementing
   c. 3 deploying
6. IPv4 to IPv6 within the same organization
   a. 1 using NAT-PT
   b. 2 implementing
   c. 2 deploying

I would like to encourage anyone who would answer Yes to any question to
respond if you haven't already.

One goal of prioritization is to decide what order to focus efforts on,
if we cannot do them all simultaneously with the same energy.

Some tentative observations from the poll so far
(we'll see if this changes based on any more responses)
1) all of the scenarios are important to someone
2) Scenario 3 seems the least urgent
3) Scenarios 1, 2, 4, and 5 are all fairly urgent.
4) Scenario 4 is the most popular scenario for IPv4-initiated communication

1, 2, and 5 all have the common property of being initiated from the IPv6
side (and hence some of the same solutions may apply).

If others have strong feelings or data to point out, please
do so (here on the list).  If you want to comment on
"Do you see a clear operational requirement for <pick a number>"
this would be a good time to start if you haven't already.
