Dear Colleagues,
Following on our tradition from last IETF meetings, ISOC has put
together the following "Rough Guide" to IETF 75 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,

------------------------------------------
ISOC's Rough Guide to IETF 75's Hot Topics
------------------------------------------
IETF 75 in Stockholm is rapidly approaching (26-31 July). With almost
120 working groups (WGs) (http://www.ietf.org/dyn/wg/charter.html)
active in eight IETF areas (not to mention the BoFs, plenaries, IAB,
IRTF, and other work) there is a lot to try to keep up with. So once
again the Internet Society's Standards & Technology team, with help from
our Trust & Identity colleagues, has prepared a rough guide to some of
the most interesting developments and discussions on the agenda, as they
relate to the Internet Society's current activities.
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, plenaries, and other events in the following broad
categories:
- Global Addressing
- Common and Open Internet
- Security and Stability
- Trust and identity
[All times listed are local (Stockholm, UTC+2). Check agendas for
updates as the meeting progresses.]
--------------------------
Global Addressing
--------------------------
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.
alto (Application-Layer Traffic Optimization)
---------------------------------------------
The alto WG is chartered to design and specify a service that will
provide P2P applications with information to perform better-than-random
initial peer selection. This service may take different approaches at
balancing factors such as maximum bandwidth, minimum cross-domain
traffic, lowest cost to the user, and others.
Full charter: http://www.ietf.org/html.charters/alto-charter.html
IETF 75 is shaping up as an opportunity for the community to discuss the
newly-merged solution proposal and associated drafts.
Agenda: http://www.ietf.org/proceedings/09jul/agenda/alto.html
(28 July, 13:00-15:00)
ledbat (Low Extra Delay Background Transport)
---------------------------------------------
As mentioned in previous rough guides, ledbat is chartered to produce a
congestion control algorithm that simultaneously saturates the
bottleneck link in an end-to-end path, maintains low delay, and (most
importantly) yields to standard TCP. Such a congestion control
algorithm, if used by bandwidth-intensive applications (such as P2P data
transfer applications), would enable the simultaneous use of real-time
communication applications (such as voice-over-IP) without noticeable
problems.
Full charter: http://www.ietf.org/html.charters/ledbat-charter.html
At the time of writing, there was no agenda for this WG. However, a
draft solution
(http://tools.ietf.org/html/draft-shalunov-ledbat-congestion-00) has
been published and IETF 75 presents another opportunity for community
feedback and discussion.
(29 July, 13:00-15:00)
MPTCP (Multipath TCP) BOF
-------------------------
Multipath TCP is a proposed new IETF activity to add the capability to
use multiple connection paths in a single TCP connection. The
availability of multiple connection paths and the capability to
dynamically schedule traffic between them allows more flexibility and
efficiency in Internet congestion control, in addition to other
benefits.
Agenda:
http://trac.tools.ietf.org/area/tsv/trac/wiki/MpTcpBofDescription
(30 July, 09:00-11:30)
Technical Plenary - Network Neutrality
--------------------------------------
The Internet Architecture Board has arranged this important plenary
session to discuss network neutrality and place it within the IETF
context by presenting the network neutrality debate and its implications
to the IETF community.
Agenda: http://www.ietf.org/proceedings/75/agenda/plenaryt.txt
(30 July, 17:00-19:30)
--------------------------
Common and Open Internet
--------------------------
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
During IETF 75, there will be detailed discussions of each of these
protocols with a particular focus on advancing the specification for
neighbor discovery using IPv6 for these kind of low-powered, limited
bandwidth, and limited connectivity type of devices.
Agenda: http://www.ietf.org/proceedings/09jul/agenda/6lowpan.txt
(28 July, 09:00-11:30)
6man (IPv6 maintenance)
-----------------------
This WG is home for discussions of improvement and maintenance of the
IPv6 protocol suite.
Full charter: http://www.ietf.org/html.charters/6man-charter.html
Topics at IETF 75 will include a canonical representation of IPv6
addresses, and ongoing work to update the IPv6 node requirements
document (RFC4294, http://tools.ietf.org/html/rfc4294).
Agenda: http://www.ietf.org/proceedings/09jul/agenda/6man.html
(29 July, 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
Five hours have been scheduled for behave at IETF75, with an agenda full
of discussions on these protocol translation discussions. There will
also be a discussion on issues with large scale NATs (which have been
proposed by some as a means of extending the life of IPv4). It remains
to be seen whether such proposals in this context have enough benefits
to outweigh the new set of operational limitations they impose on
existing networks.
Agenda: http://www.ietf.org/proceedings/09jul/agenda/behave.html
(27 July, 09:00-11:30; 28 July, 09:00-11:30)
softwire (Softwires)
--------------------
The softwires WG looks at discovery, control, and encapsulation methods
for connecting IPv4 networks across IPv6-only networks and IPv6 networks
across IPv4-only networks in a way that will encourage multiple,
inter-operable vendor implementations.
Full charter: http://www.ietf.org/dyn/wg/charter/softwire-charter.html
At the time of writing, the softwires agenda had not been posted, but
look out for topics relating to shared addressing. Expect discussion of
the dual-stack-lite architecture and protocol proposal which may become
an important transition mechanism for IPv6 deployments.
(http://www.ietf.org/internet-drafts/draft-ietf-softwire-dual-stack-lite
-01.txt)
(29 July, 09:00-11:30)
v6ops (IPv6 Operations)
-----------------------
The v6ops WG exists to discuss operational issues in deployment of IPv6.
Full charter: http://www.ietf.org/html.charters/v6ops-charter.html
In the four hours of meeting time scheduled at this meeting, v6ops will
explore a number of important issues. Of particular interest are
discussions of how some IPv6 tunnels are considered harmful and the
requirements for IPv6 CPE devices. There is also a discussion planned of
an incremental carrier grade NAT for facilitating transition to IPv6.
Agenda: http://www.ietf.org/proceedings/09jul/agenda/v6ops.html
(28 July, 13:00-18:10)
--------------------------
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.
Securing the DNS Panel
----------------------
ISOC's Securing the DNS panel is not an IETF event, but will help take
some of the important work of the IETF to a broader audience. Featuring
speakers from .SE, ICANN, IAB, ISOC, PIR, and Verisign, the panel will
highlight the opportunities flowing from a more secure DNS. This panel
is now fully booked, but there will be a live audiocast (also archived
for future reference).
More details: http://www.isoc.org/dns
(28 July, 11:45-12:45)
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
Since dnsext did not meet at IETF 74, its agenda is larger than usual,
mostly concerned with security issues. Three drafts to be discussed
propose new algorithms for DNSSEC, one of which is a Russian national
standard. There are also five drafts proposing security improvements to
DNS other than DNSSEC, which remain unresolved from last year. Another
draft under consideration proposes a mechanism for a validator to signal
the server which algorithms it supports.
Agenda: http://www.ietf.org/proceedings/75/agenda/dnsext.txt
(29 July, 13:00-15:00)
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
Some of the new drafts in dnsop include a trust history tracker to help
DNSSEC validators catch up if they miss trust-anchor changes, as well as
a description of dns-redirect (which is controversial because it
involves recursive resolvers returning modified - not authoritative -
answers under certain circumstances documented in this draft).
Agenda: http://www.ietf.org/proceedings/75/agenda/dnsop.txt
(27 July, 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
Although the agenda has not been posted, there is an open discussion
from IETF 74 about the savi charter, specifically whether a proposed
development (preventing hosts from using unassigned IP addresses) would
amount to a charter extension.
(30 July, 09:00-11:30)
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
The sidr agenda for Stockholm ranges across revisions of the ongoing
drafts on the RPKI architecture, Route Origin Authorization, certificate
policy, RPSL with RPKI signatures, and a new draft of use cases for RPKI
objects.
Agenda: http://www.ietf.org/proceedings/75/agenda/sidr.html
(30 July, 09:00-11:30)
--------------------------
Trust and identity
--------------------------
As public concerns increase about security of infrastructure, privacy,
trust, and identity on the Internet, these themes recur in several
working group discussions.
ogpx (Open Grid Protocol) BoF
-----------------------------
This BoF is proposing a WG to provide an application-layer wire protocol
for virtual worlds to enable interoperability between applications,
provide for access and exchange with other systems on the internet, and
allow network layers to recognize VW traffic and make routing decisions
based on its characteristics. It's of particular interest to ISOC's
Trust and Identity work because of the proposed use of TLS and OAuth for
origin authentication.
(28 July, 15:20-17:00)
oauth (Open Authentication Protocol)
------------------------------------
OAuth allows a user to grant a third-party Web site or application
access to their resources, without necessarily revealing their
credentials, or even their identity.
Full charter: http://www.ietf.org/dyn/wg/charter/oauth-charter.html
This recently chartered WG will not meet formally at IETF 75, but a "Bar
BoF" has been tentatively scheduled for Wednesday 29 July, 7:30am.
Recently submitted drafts (http://tools.ietf.org/wg/oauth/) and the
Google OpenID/OAuth projects
(http://code.google.com/apis/accounts/docs/OpenID.html) are likely
topics of discussion.
dkim (Domain Keys Identified Mail)
----------------------------------
The DKIM working group will produce standards-track specifications that
allow a domain to take responsibility, using digital signatures, for
having taken part in the transmission of an email message and to publish
"policy" information about how it applies those signatures.
Full charter: http://www.ietf.org/dyn/wg/charter/dkim-charter.html
In Stockholm, the dkim WG will focus on next steps, as well as update to
RFC4871 (http://www.ietf.org/rfc/rfc4871.txt) will be discussed. There
is also interest both in stream lining the current feature set and in
gathering data on usage.
(28 July, 13:00-15:00)
--------------------------
Also watch out for...
--------------------------
lisp (Locator/ID Separation Protocol)
-------------------------------------
The lisp WG working group is chartered to produce an experimental
protocol that separates identifiers and locators.
Full charter: http://www.ietf.org/html.charters/lisp-charter.html
In Stockholm, lisp will discuss ongoing refinement of the experimental
protocol specification and explore some ideas about how to provide
functionality to support it.
Agenda: http://www.ietf.org/proceedings/09jul/agenda/lisp.txt
(27 July, 13:00-15:00)
rrg (Routing Research Group)
----------------------------
The Routing Research Group (rrg) is an IRTF WG exploring routing and
addressing problems that are important to the development of the
Internet but are not yet mature enough for engineering work within the
IETF.
Full charter: http://www.irtf.org/charter?gtype=rg&group=rrg
Again, no agenda is yet available. This group has been discussing
strategies for dealing with routing in the future Internet, particularly
the growth of routing and forwarding tables in the medium term and ways
to mitigate growth outrunning the ability for current hardware
technology to keep up.
(31 July, 09:00-15:15)
Transport Area Open Meeting
---------------------------
This is an open meeting for the Transport Area of the IETF. There is
typically novel and stimulating work on the agenda and this meeting is
no exception. Several presentations will deal with http, the protocol
that powers the web. These include improvements to enhance the end-user
experience during the transition to IPv6 ('Happy Eyeballs') and to
improve web browser capabilities when dealing with mirrored information
services.
Agenda: http://www.ietf.org/proceedings/09jul/agenda/tsvarea.txt
(27 July, 15:20-17:20)
