If I may, I'd like to try and re-focus the discussion of 2018-1 on the<br>
network engineering problem that prompted this draft proposal. The<br>
solution this draft policy proposal offers to the problem is where I think<br>
the real value is, and where I think PPML needs to focus.<br>
<br>
Since the publication of RFC1997 in the 1996, network engineers have<br>
utilized an extension of BGP called the BGP communities attribute to<br>
enginer traffic (to "shape traffic") in a desirable way.<br>
<br>
RFC1997 only supports the use of 2-byte ASNs. As the free pool of 2-byte<br>
ASNs began to shrink, a solultion was needed to enable networks<br>
labelled with 4-byte ASNs to utilize BGP community attributes.<br>
<br>
In 2010, a draft of Flexible Community attribute was discussed, but no<br>
working code was widely released. In 2016, a draft of Wide Comunity<br>
attributes was released, but also resulted in no working code. Finally,<br>
in February 2017, RFC8092 was published, and Large BGP Communities became<br>
the protocol standard for defining 4-byte AS numbers within the BGP<br>
community attribute.<br>
<br>
Working code exists for some equipment and software, is planned for other<br>
equipment and software, but the point is that RFC8092-compliant code is<br>
not prevelant in the DFZ. This is important because it means a network<br>
operator who wants to shape their traffic properly with BGP communities<br>
still needs a 2-byte ASN or it won't work.<br>
<br>
This proposal addresses the problem by allowing registrants of an unused<br>
or unwanted 2-byte ASN to transfer the registration to a network operator<br>
who needs one, all within the existing and community agreed-upon framework<br>
of Inter-RIR transfers.<br>
<br>
For this reason, I support draft policy proposal ARIN-2008-1.<br>
