Hi Xu, My first impression on reading over your HRA proposal is that it involves changed host behaviour.
If this is the case, then I don't think HRA can be considered alongside LISP, eFIT-APT, Ivip or TRRP - all of which are intended to work for current and future hosts without any new host host requirements. I think HRA or any other system which requires host changes is probably about as hard to introduce as IPv6: There seems to be no strong enough immediate benefit for most early adopters to create anything like widespread or ubiquitous adoption - and in the meantime (~= forever) all ordinary Internet users still need full IPv4 connectivity. - Robin -- to unsubscribe send a message to [EMAIL PROTECTED] with the word 'unsubscribe' in a single line as the message text body. archive: <http://psg.com/lists/rrg/> & ftp://psg.com/pub/lists/rrg
