hi Med, all,

Thanks for writing this, it helps.
A couple of quick comments below,

*) Is the focus of the document (properties used) on the whole address architecture/format, or just on the algorithms to build port sets? As in some proposals, for example 4rd, the port indexing algorithm can be an independent part and decoupled from the address format.

*)
   o  Multiple Port Ranges: Capability to assign multiple contiguous
      port ranges to a single PRD

Jacni>: I guess this only applies to "portrange" which offers contiguous port-set. So, I would suggest removing this property.

*) For "despres-4rd",
Differentiated Port Sets Supported, through different piece of rules, delegated CPE prefixes of different length.
IPv4 traffic Isolation   supported
Prefix Aggregation supported, since the IPv6 address planning is not affected.

I'll come back to you later if I get more.


Cheers,
Jacni

Dear all,

We have just submitted an I-D analysing the port set algorithms we have on the table. A set of properties are used to characterize the port set algorithms.

This is a call for review. In particular, we invite authors of the following proposals to review their section:

o [I-D.boucadair-behave-ipv6-portrange]
o [I-D.xli-behave-divi]
o [I-D.murakami-softwire-4v6-translation]
o [I-D.murakami-softwire-4rd]
o [I-D.despres-softwire-4rd-addmapping]

Questions, suggestions, corrections and contributions are more than welcome.

Thank you.
Cheers,
Med

Title : Analysis of Port Indexing Algorithms

This document analyzes various algorithm proposals for building port
sets. These algorithms are used to encode the range of ports in an
IPv6 address and prefix in the context of stateless solutions. The
ultimate goal of this analysis is to converge on one or a set of
algorithms to be used by all stateless solutions.

This is a companion document to
[I-D.boucadair-softwire-stateless-rfc6052-update].
