Instructions for Seamoby and Experimental Mobility Protocol IANA Allocations
RFC 4065

Sent James RFC Editor notes after waiting to see issues from iesg review/re-review of card/ctp.

1. Change the shared SCTP port for CARD and CTP, to one each, and
  have them not use PPI's.  The IESG has actually preferred to encourage
  that SCTP not substitute PPIs for ports, and SCTP ports are not scarce.
  We missed this point earlier.

  The text changes for this are (I'll put them in RFC Editor notes on the
  announcement, no revision needed):

  OLD:

    2.0    Common IPv4 and IPv6 Allocations

    IANA SHALL assign SCTP port number TBD1 for use by experimental mobility
    protocols such as Seamoby. See Section 5.2.1 of [CARD] for a description of
    inter-access router CARD protocol use of SCTP, and Section 3.1 of [CTP] for
    a description of the inter-access router CTP use of SCTP.

    IANA SHALL assign SCTP Payload Protocol Identifier (PPI) TBD2, designated
    "CTP", for the Context Transfer Protocol, and SCTP Payload Protocol
    Identifier TBD3, designated "CARD", for the Candidate Access Router
    Discovery protocol. These are used to differentiate inter-router CARD and
    CTP messages on the SCTP port. The allocation policy for new PPI numbers is
    the method of IETF Consensus Action.


  NEW:

  2.0    Common IPv4 and IPv6 Allocations


    IANA SHALL assign SCTP port numbers TBD1 for use by [CARD] and TBD1a for use
    by [CTP].  See Section 5.2.1 of [CARD] for a description of
    inter-access router CARD protocol use of SCTP, and Section 3.1 of [CTP] for
    a description of the inter-access router CTP use of SCTP.


  OLD:

  9.0    Utilization by Other Experimental Mobility Protocols

    The ICMP Experimental Mobility type code and SCTP port are available for
    other experimental mobility protocols to utilize. Other experimental
    mobility protocols MAY define additional ICMP messages that utilize the code
    points under the Experimental Mobility ICMP type, and MAY define protocols
    that utilize additional SCTP PPI numbers for the Experimental Mobility
    protocol por

  9.0    Utilization by Other Experimental Mobility Protocols

    The ICMP Experimental Mobility type code is available for
    other experimental mobility protocols to utilize. Other experimental
    mobility protocols MAY define additional ICMP messages that utilize the code
    points under the Experimental Mobility ICMP type.


2. There's an RFC 2434 mistake, a category that doesn't exist.  The only
  way to guarantee IESG review is the IETF Consensus category; this requires
  an RFC publication and an IESG review.  Text change:

  OLD:

    Subsequent allocations of subtype codes SHALL be done by the method of
    Specification Required and IESG Review as defined in RFC 2434.

  NEW:

    Subsequent allocations of subtype codes SHALL be done by the method of
    IETF Consensus as defined in RFC 2434.

resusing the port  for multiple applications seems not so good. Why
not just assign a port number for CARD and be done with it?

IESG Review is not defined in 2434...

Comment worth pulling into ballot:

5.2 - Given that the registry is starting with 8 values, and this is
just from IEEE 802, I'm wondering if one byte (255 values) leaves
enough headroom for the next 20 years. I guess it's BARELY big enough.
Yeah, Seamoby is Experimental, but what if the experiment works?

But John Loughney responded (on the gen-art list):

Strong guidence from the AD & Thomas Narten suggested that this space
be left small intentially to avoid potential over extension.  However,
if the experiment works, then the document will be reved as proposed
standard with this fixed, if needed.

It might be helpful if section 12 (IANA Considerations) spelled out the TBD actions that are sprinkled throughout the document instead of just saying that "This entire document is about IANA considerations".  It's easy to miss an action given the way the document is currently written.
