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. [Med] All port indexing schemes are independent of the address format itself, but we included some properties to reflect some design choices made my the authors of these solutions on the address format. FWIW, we will submit soon a list of requirements to be followed by stateless address/prefix 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. [Med] Ok. *) For "despres-4rd", Differentiated Port Sets Supported, through different piece of rules, delegated CPE prefixes of different length. [Med] the concern is more on the border router side, can you please check if the operations are still stateless at the border side? BTW, I'm envisaging having two properties here: (1) Differentiated Port Sets (network level) (2) Differentiated Port Sets (bound to the same shared address) IPv4 traffic Isolation supported [Med] Ok. This is supported by assigning two prefixes. Prefix Aggregation supported, since the IPv6 address planning is not affected. [Med] Ok. I'll come back to you later if I get more.

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.

Title : Analysis of Port Indexing Algorithms Author(s) : Mohamed Boucadair Nejc Skoberne Wojciech Dec Filename : draft-bsd-softwire-stateless-port-index-analysis-00.txt Pages : 25 Date : 2011-09-05 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.
