Re: [alto] I-D Action: draft-ietf-alto-performance-metrics-15.txt

Hi ALTOers,

This is the revised version of the document, addressing comments and issues
identified by Danny, Jensen, Kai, authors and some comments from our
wonderful chairs.

One "interesting" change is
2001:db8::1:2345:6789:abcd -> 2001:db8::1234:5678
to make sure that the ipv6 range is within the range of Table 25 of RFC
6890.

Cheers,
Richard
