[Chapter-delegates] A Rough Guide to ISOC's IETF73 Hot Topics

[Anne Lord]

Dear Colleagues,

ISOC's Standards & Technology group has put together the following 
information as a "rough guide" to hot topics in the forthcoming IETF.

They are also seeking feedback on whether this information is useful to 
you as a participant or potential participant (remote or in person). 
Comments are welcome on or off list.

Best wishes

Anne

A Rough Guide to ISOC's IETF73 Hot Topics

ISOC's Standards & Technology department offers the following "rough 
guide" to hot topics being discussed at the 73rd IETF meeting in 
Minneapolis (November 16-21, 2008).  This simply indicates which meeting 
sessions are particularly focused on the following topics:

- Bandwidth Management
- IPv4/IPv6 Coexistence
- DNSSEC
- Trust and Identity

Remote participation in all meetings will be possible -- see specific 
meetings listed on http://tools.ietf.org/agenda/73/ for access to audio 
stream and jabber rooms.  That page also includes links to helpful 
tarballs of documents being discussed at meetings, etc.

For the full IETF meeting plan and agenda, see 
http://www.ietf.org/meetings/73/


Bandwidth Management
--------------------
As P2P and VoIP technologies become more prevalent, and network usage 
patterns sometimes deviate from their architects' expectations, 
management of bandwidth to allow best use for customers becomes an 
increasingly important topic.

Key meetings at IETF73:

ALTO WG -- application techniques for identifying and using bandwidth 
parameters.

Designing and specifying a service that will provide applications with
information to perform better-than-random initial peer selection based 
on factors including maximum bandwidth, minimum cross-domain traffic, 
lowest cost to the user, etc.

Currently scheduled:  Tuesday, November 18, 13:00-15:00
WG agenda: http://tools.ietf.org/agenda/73/alto.html
WG page: http://www.ietf.org/html.charters/alto-charter.html

LEDBAT WG -- alternative transport congestion management techniques
Chartered to standardize a congestion control mechanism that should 
saturate the bottleneck, maintain low delay, and yield to standard TCP.
What this means in practice - applications that do large background 
transfers (e.g. P2P apps) could use this mechanism and would then 
automatically yield in the presence of bursty web traffic, or other 
TCP-using apps. Particularly useful for P2P uploads on thin home uplinks.

Currently scheduled:  Thursday, November 20, 13:00-15:00

IPv4/IPv6 Coexistence
---------------------
As there is increasing momentum to deploy IPv6, as well as recognition 
that IPv4 and IPv6 network realities must coexist, work is being done to 
develop specifications to allow interoperable behaviour between 
networked realities.

BEHAVE WG -- NAT standardization WG
Carrier Grade NAT (CGNAT), alternatives to CGNAT, new approaches to 
v4/v6 translation, IPv6 NAT

Currently scheduled for 3 meeting sessions from Wed through Friday
WG page: http://www.ietf.org/html.charters/behave-charter.html
WG agenda:  http://tools.ietf.org/agenda/73/behave.html


SOFTWIRE WG -- DSlite dual stack
Tunneling IPv6 over IPv4 to enable incremental IPv6 deployment and to 
address the imminent IPv4 address shortage for large providers.

Currently scheduled:  Thursday, November 20, 17:40-19:30
WG page: http://www.ietf.org/html.charters/softwire-charter.html
WG agenda: http://tools.ietf.org/agenda/73/softwire.html [not available 
as of this writing]


DNSSEC
------
While the US Department of Commerce is calling for input on the question 
of signing the DNS root (using DNSSEC), IETF working group discussions 
will be focused on refinements of the technology, and consideration of 
implications of IPv6 NATing (for coexistence with IPv4) and DNSSEC.

DNSEXT WG -- DNS extensions

Currently scheduled:  Tuesday, November 18, 15:20-17:00
WG page:  http://www.ietf.org/html.charters/dnsext-charter.html
WG agenda:  http://tools.ietf.org/agenda/73/dnsext.html

BEHAVE WG -- for implications of DNSSEC & v4/v6 NATing

WG page: http://www.ietf.org/html.charters/behave-charter.html
WG agenda: http://tools.ietf.org/agenda/73/behave.html


Issues of Trust and Identity
----------------------------
As concerns increase about security of infrastructure, privacy, trust 
and identity on the Internet, these themes are appearing in several 
working group discussions.

DKIM WG -- e-mail infrastructure
Currently scheduled:  Thursday, November 20, 13:00-15:00
WG page:  http://www.ietf.org/html.charters/dkim-charter.html

WG page:  http://www.ietf.org/html.charters/geopriv-charter.html
WG agenda:  http://tools.ietf.org/agenda/73/geopriv.html


SIDR WG -- resource certification
Currently scheduled:  Monday, November 17, 13:00-15:00
