[v6ops] protocols without need for ALG ?

[Toerless Eckert <[e-mail]>]

For autonomic networking (ANIMA WG), we are planning to rely only on IPv6 for initial
autonomic connectivity, and the question of connecting this (at least initially)
to IPv4 only NOC equipment came up. Alas, IPv6 support in transport seems to be still
weak on a range of commonly used NOC tools.

If i understand the NAT RFCs and behave output correctly, we primaerily
want ALGs to go the way of the dodo, so i was wondering if there might be
any crucial protocols between typical NOC equipment and network devices that
would require ALGs. And better of course:knowing which protocols would be fine
without ALG.

Are there any lists about this (eg: what requires ALG ?)

Wrt to what seems to be important between NOC and network devices:

   FTP     - NOK (requires ALG) - IMHO not a problem
   traceroute - ??  (initiated from v4 NOC) ??
   telnet  - OK 
   ping    - OK ?
   SSH/SCP - OK
   syslog  - OK
   TFTP    - OK ?
   radius  - OK ? (i ran some tests, seemed to be fine)
   diameter/tacacs+ - OK ?
   NTP     - OK ???

   For the following, that have extensible data-models (MIBs/OIDs, XML schema etc.),
   i can see that some NOC tools relying on them might not support data-models
   with IPv6, but that would be "fine" (aka: can't manage everything from such tools,
   but transport stack works):

   netconf - OK ?
   SNMP    - OK ?

Whats the next most important NOC<->network management protocols... ?

Thanks!
