- Reported by Robert Hinden/SUN
-
- Minutes of the IP Address Encapsulation Working Group (IPAE)
-
- This meeting of the IPAE Working Group took place on September 24, 1992
- in a Video Conference between Mt. View, CA and Lincoln, MA
-
-
- 1. Reviewed Agenda Items.
- 2. Reviewed Action Items from Previous Meeting.
- 3. Review of Recent Work.
- ICMP
- Reviewed G. Chesson's ICMP extensions. Decided that an IPAE
- redirect was necessary, but that special Destination unreachable
- was not needed.
- ACTION: Chesson to update work and write up mechanism to map ICMP
- error messages between commonwealths assuming that sender includes
- IPAE header in ICMP error message.
- Addressing
- Reviewed work of previous days addressing meeting.

- ACTION: Steve Deering to write IPAE addressing architecture and
- hold follow addressing sub-group meeting to review writeup.
- Commonwealth Router Discovery
- Concluded that discovery mechanism proposed by John Moy/Proteon
- would be fine.
- ACTION: Hinden to get IP address assigned for Commonwealth router
- discovery.
-
- 4. Close Outstanding Technical Issues
- DNS SUPPORT
- Discussed where changes to DNS would be necessary and which DNS
- servers would have to support IPAE at each stage in the transition.
- ACTION: Crocker to bring DNS experts into loop and write up details
- for document.
- Inter-Commonwealth Routing
- Discussed and concluded that for provider based addressing, use
- BGP4 with support for 96bit IPAE addresses. Metro based routing
- some what harder.
- ACTION: Deering to write up routing approach.
- ACTION: Hinden to discuss w/Yakov Rekhter about adding support for
- 96-bit addresses to BGP4.
-
- 5. Transition Issues
- 32-BIT IP Address => Commonwealth Address Mapping
- Discussed different approaches: Static table, pure DNS, and hybrid
- consisting of background DNS collection to local server + real time
- query by Commonwealth Router to local server.
- ACTION: Hinden to write up static approach.
-
- 6. Implementation Plans and Schedule
- SGI, Proteon, and Sun intend to build prototype IPAE
- implementations. Minimum test configuration need was:

- Testing can be done with out building any new infrastructure. It
- can be done using existing internet.
- Implementation subgroup will be formed. Bob Gilligan agreed to
- lead and coordinate.
- ACTION: Gilligan to set up implementors meeting and develop testing
- plan.
