Dear Colleagues,
Following on our tradition from last IETF meetings, ISOC has put
together the following "Rough Guide" to IETF 76 touching on topics of
interest.
Please feel free to share it with any of your members, or any one else
you think might make use of it. We hope it is of interest and helpful.
Kind regards,
Sabrina Wilmot

=============================================
ISOC's Rough Guide to IETF 76's Hot Topics
=============================================
IETF 76 in Hiroshima, Japan is upon us (8-13 November). As we have done
in previous meetings, the Internet Society has compiled this Rough Guide
to help you keep up with the IETF meeting sessions of particular
relevance to the Internet Society's current activities. Within that
context, the Standards & Technology team, with input from our Trust &
Identity colleagues, has previewed the most interesting developments and
discussions on the agenda.
We hope this guide will be helpful to those who are attending the
meeting as well as those who will follow remotely. Remember, although
the physical meetings provide excellent opportunities for informal
contact, in formal terms they are no more important than the mailing
list discussions which are continuous and open to all.
In line with our own priorities at the Internet Society, we've selected
working groups, BoFs, and other events in the following broad categories:
- Common and Open Internet
- Global Addressing
- Security and Stability
All times listed are local (Hiroshima, UTC+9). Check agendas for updates
as the meeting progresses.
Many of the critical agendas have only become available very recently,
so please accept our apologies for presenting this Rough Guide a little
later than usual.
Finally, in addition to the main IETF content, don't forget to follow
ISOC's latest expert panel "Internet Bandwidth Growth: Dealing with
Reality", on Tuesday 10 November. Agenda and audiocast details here:
http://www.isoc.org/isoc/conferences/bwpanel/
========================================
Common and Open Internet
========================================
As P2P and VoIP technologies become more prevalent, and network usage
patterns sometimes deviate from their architects' expectations, managing
bandwidth to allow best use for customers becomes an increasingly
important topic.
mptcp (Multipath TCP) BOF
----------------------------------------
This is a new working group since the succesful BoF meeting held during
IETF75. The Multipath TCP (MPTCP) working group develops mechanisms that
add the capability of simultaneously using multiple paths to a regular
TCP session. The primary output of the group will be the protocol
extensions needed to deploy MPTCP, and adaptations to congestion control
to safely support multipath resource sharing. Initially the WG will only
produce documents that are experimental or informational.
Full charter: http://www.ietf.org/dyn/wg/charter/mptcp-charter.html
This work has the potential to greatly improve robustness and resilience
of Internet connectivity for multihomed sites.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/mptcp.txt
(9 November, 17:40-19:40)
conex (Congestion Exposure) BOF
----------------------------------------
Congestion Exposure (ConEx) is a proposed new IETF activity to enable
congestion to be exposed along the forwarding path of the Internet. By
revealing expected congestion in the IP header of packets, congestion
exposure provides a generic network capability which allows greater
freedom over how capacity is shared. Such information could be used for
many purposes, including congestion policing, accountability and
inter-domain SLAs. It may also open new approaches to QoS and traffic
engineering.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/conex.txt
(10 November, 15:20-18:10)
homegate (Broadband Home Gateway) BOF
----------------------------------------
This is a new initiative. Device manufacturers, and/or the organizations
what specify requirements for such devices, are not certain which IETF
standards and best current practices should be supported, and when/why
that support is needed. As a result of this, millions of devices are
being deployed every year which do not work with important IETF
protocols, standards, and best practices that are central to the future
of the Internet. The primary objective of this group is to document a
baseline of 'core' RFCs/BCPs which must be supported, followed by some
'advanced' RFCs/BCPs which are to be considered optional. A secondary
problem is compatibility with and capability for the use of the Internet
of tomorrow. New security needs related to DNS are motivating a move to
DNSSEC. However, many if not most home gateways cannot handle DNSSEC,
which is expected to be a major problem that could significantly impede
the deployment of DNSSEC globally. Support for IPv6 is also lacking to a
great degree and there is no clear understanding of how such devices
should support IPv6.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/homegate.txt
(9 November, 15:20-17:20)
ppsp (Peer to Peer Streaming Protocol)
BOF
----------------------------------------
The purpose of PPSP BOF is to determine whether a working group should
be formed to develop standard signaling protocols (called PPSP
protocols) for multiple types of entities (such as intelligent
endpoints, caches, content distribution network nodes, and/or other edge
devices) to participate in P2P streaming systems in both fixed and
mobile Internet.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/ppsp.html
(12 November, 13:00-15:00)
========================================
Global Addressing
========================================
There is steadily increasing momentum to deploy IPv6 as the IPv4 address
pool approaches depletion. While much work is ongoing to support
interoperability in coexisting IPv4 and IPv6 network environments, there
are also interesting developments in emerging IPv6 environments.
6lowpan (IPv6 over Low power WPAN)
----------------------------------------
The 6lowpan WG deals with the use of IPv6 over low powered networks
(such as sensornets). This is protocol development for devices on "the
Internet of Things". The basic concept in 6lowpan is that IP may become
a unifying layer for low powered devices for interoperability,
potentially over the Internet. 6lowpan is intensely focused on
developing the protocols to enable this to happen.
Full charter: http://www.ietf.org/html.charters/6lowpan-charter.html
Some progress should be made in closing on standardization of a couple
of documents (specifically the Neighbor Discovery document).This working
group has been going on for some time and has a sense of urgency now due
to the SmartGrid efforts currently gaining a lot of attention in the
United States.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/6lowpan.txt
(10 November, 13:00-15:00)
behave (Behavior Engineering for
Hindrance Avoidance)
----------------------------------------
While behave was chartered to create mechanisms for transiting NATs in
reliable ways, most of its activity is now focused on protocol
translation from IPv4 to IPv6 in a number of different scenarios. Of
particular interest in these scenarios is how the proposed mechanisms
deal with DNS operation across the two protocol realms (and whether it
is possible to maintain any kind of reasonable operation of secure DNS
in such a scenario).
Full charter: http://www.ietf.org/html.charters/behave-charter.html
A great deal of cycles continue to be spent on 6to4 protocol translation
standardization.Two of the hot issues should be the handling of DNS for
these situations and the handling of fragmentation in a number of scenarios.
Agenda: http://www.ietf.org/dyn/wg/charter/behave-charter.html
(11 November 09:00-10:15)
v6ops (IPv6 Operations)
----------------------------------------
The IPv6 Operations Working Group (v6ops) develops guidelines for the
operation of a shared IPv4/IPv6 Internet and provides operational
guidance on how to deploy IPv6 into existing IPv4-only networks, as well
as into new network installations.
Full charter: http://www.ietf.org/html.charters/v6ops-charter.html
Discussion in Hiroshima will include recommendations for IPv6 CPE
devices, new transition tools, new measurements of IPv6 traffic, IPv6
deployment scenarios for ISPs, and IPv6 deployment in Internet exchange
points, amongst other topics.
Agenda: not yet published
(10 November, 13:00-15:00)
aplus (Address Plus Port) BOF
----------------------------------------
There are a couple of efforts underway to standardize the use of NATs
further in the network rather than at the edges. One of the approaches
is called DS-lite and it is being standardized in softwires.Another
approach uses address and port sharing. It may be used on its own or in
a way to supplement DS-lite. As an output of the Internet Society IPv6
Roundtable event in the Spring, Mat Ford updated the Internet draft on
problems with address sharing
(http://tools.ietf.org/html/draft-ford-shared-addressing-issues-01) and
this draft will be discussed in this BOF (as well as in softwires).
Agenda: http://www.ietf.org/proceedings/09nov/agenda/aplusp.html
(11 November, 13:00-15:00)
6lowapp (Application Protocols for
Low-power v6 Networks) BOF
----------------------------------------
6LOWAPP is a BOF considering whether different protocols, or
modifications to existing protocols, are needed for very low power
devices that may proliferate for sensor type networks. There is a great
deal of enthusiasm not just to define the work of a potential working
group coming out of this BOF but also to start defining problems and
protocols. The mailing list for this BOF has a lot of traffic and the
BOF promises to be vigorous.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/6lowapp.txt
(9 November, 13:00-15:00)
========================================
Security and Stability
========================================
Securing the DNS and greater assurance in routing is critical for the
ongoing expansion and evolution of the Internet in all areas of our
societies and economies.
dnsext (DNS Extensions)
----------------------------------------
This working group is involved in developing a wide range of functional
extensions to the DNS. dnsext also tracks the DNS implications of the
behave WG.
Full charter: http://www.ietf.org/dyn/wg/charter/dnsext-charter.html
Most of this meeting is devoted to extensions related to DNSSEC,
including registry states, registration rules, the GOST draft already in
wg-last-call, and DNSSEC-bis-updates. The other topic, transport for
DNS, is prompted by the larger answers that DNSSEC will produce.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/dnsext.txt
(9 November, 17:40-19:40)
DNSOP (Domain Name System Operations)
----------------------------------------
The dnsop WG works on various operational aspects of the Domain Name System.
Full charter: http://www.ietf.org/dyn/wg/charter/dnsop-charter.html
Several drafts in this WG relate to DNSSEC, including key timing
considerations, trust anchor history, signing policy, and practice
statement framework. Transport considerations for DNS are here as well
as in dnsext. Other topics are initializing a DNS resolver with priming
queries, and reverse DNS in IPv6.Top-level domains are considered in two
drafts. Finally, DNS implications in BEHAVE and MIF are to be discussed.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/dnsop.txt
(11 November, 13:00-15:00)
sidr (Secure Inter-Domain Routing)
----------------------------------------
The sidr WG working group is chartered to formulate an extensible
architecture for an inter-domain routing security framework.
Full charter: http://www.ietf.org/dyn/wg/charter/sidr-charter.html
Draft updates on repository structure, certificate profile, provisioning
protocol, ROA validation, and trust anchors are expected from their
authors. Terry Manderson will discuss his use-cases draft, which he
requests the WG to adopt.Steve Kent will present his draft on Local
Trust Anchor Management, which was unveiled pre-draft at IETF 75. The
report from the operators' roundtable arranged by ISOC will be discussed.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/sidr.txt
(9 November, 09:00-11:30)
savi (Source Address Validation
Improvements)
----------------------------------------
The savi WG is chartered to design methods for IP source address
validation that complement ingress filtering with finer-grained protection.
Full charter: http://www.ietf.org/dyn/wg/charter/savi-charter.html
The savi wg continues with updates for most of its drafts on the agenda
for IETF 76.
Agenda: http://www.ietf.org/proceedings/09nov/agenda/savi.txt
(9 November, 09:00-11:30)
karp (Keying and Authentication for
Routing Protocols) BOF
----------------------------------------
Many routing protocol deployments, if they use authentication at all,
are using older (possibly deprecated) cryptographic algorithms and
missing some modern security mechanisms, like replay protection,
algorithm agility, or key rollover. In addition, many use the same key
permanently. This needs to be fixed. Additionally, key management for
routing protocols needs to be added to easily address the
terminated-employee problem of compromised shared secrets. Such key
management needs to work over multicast media, and needs to work
directly over the link layer in some cases (since routing depends upon it).
This work is intended to scope and sequence detailed work on specific
protocols to improve the security of the routing infrastructure of the
Internet.
