Internet Society's Rough Guide to IETF 85's Hot Topics 
-----------------------------------------------

IETF 85 in Atlanta is rapidly approaching (4-9 November 2012). Newcomers' training and technical tutorials take place on Sunday (4 November), with the working group (WG), Birds of a Feather (BoF), and a plenary session happening during the week.

Once again, the Internet Society is pleased to bring you a Rough Guide to the IETF 85 sessions most relevant to our current work. The online version of this Rough Guide will be updated as the IETF 85 session agendas are finalized:

http://www.internetsociety.org/rough-guide-ietf85

At this IETF meeting, we are turning our attention to the following broad categories:

- Trust technologies
- Authentication/Authorization
- Infrastructure/Support
- IPv6
- Bandwidth

(All times are local, UTC -5 hours)

In addition to the WG and BoF sessions listed below, these sessions are of general interest:

+ Plenary Technical Topic

'Measurement Issues in the Internet'

Although network performance measurement has been a topic of research, standardization, and development for decades, recent efforts to create national, regional, and global access network measurement testbeds and frameworks are drawing renewed interest. These efforts seek to provide consistent measurements of fine-grained performance metrics such as packet loss, delay, and throughput, as well as higher order tests to capture quality of experience with respect to specific applications and services. Some standardized metrics and tests exist, including those developed in the IPPM WG, but a unified framework for observing and reporting the quality metrics that define users’ experiences across different networks has yet to be developed. This plenary will explore the approaches, results, and challenges involved with existing performance measurement efforts from around the world with an eye towards understanding the potential role for standardization broadly and IETF/IRTF activity specifically.

+ ISOC at IETF 85 Briefing Panel: Internet Untethered?

The mobile data network world has changed significantly in the course of the last 4 years as game-changing smartphones have come online, tablets are hitting the scene.  Users have taken up these devices with enthusiasm, and put them to uses not ever envisioned by their creators or the operators of the networks that support them.  And with increasing speed and power (of devices and mobile data networks), users are expecting broadband Internet experience while on the move.  This panel will explore the evolution of the mobile data network reality through key questions:

How have these new devices impacted the evolution of mobile data services  and offerings of mobile Internet, especially in terms of bandwidth management?

What are the key factors in evolving from a mobile data service to mobile Internet?

Many ubiquitous web-based services (Wikipedia, Facebook, Twitter) are increasingly accessed through dedicated applications on the smartphone. What are the drivers for this and where is it taking the Internet user's reality?

Information on the briefing panelists are posted at:

irtfopen (IRTF Open Meeting)

The IRTF Open Meeting will include talks from the two remaining Applied Networking Research Prize winners for 2012. Srikanth Sundaresan was recognised for his measurement study of access link performance on home gateway devices. This talk should be nicely complementary with the technical plenary topic of 'Measurement Issues in the Internet' and the lmap discussions taking place in the Transport Area Open Meeting (Srikanth Sundaresan, Walter de Donato, Nick Feamster, Renata Teixeira, Sam Crawford and Antonio Pescape. Broadband Internet Performance: A View From the Gateway. Proc. ACM SIGCOMM,August 2011, Toronto, Canada). Peyman Kazemian was recognised for developing a general and protocol-agnostic framework for statically checking network specifications and configurations (Peyman Kazemian, George Varghese and Nick McKeown. Header Space Analysis: Static Checking For Networks. Proc. USENIX Symposium on Networked Systems Design and Implementation (NSDI), April 2012, San Jose, CA, USA).

Nominations for ANRP 2013 are open until November 30th 2012. See https://isoc.org/anrp for details.

Trust technologies
Trust technologies are those that enable trust in the Internet infrastructure and user or application space. This includes encryption technologies and mechanisms for communicating trust in various forms.
_____________________________________

jose (Javascript Object Signing and Encryption) WG

The jose WG is chartered to develop two security services, integrity protection and encryption, for data being carried in the JSON format. The four core documents, including JSON Web Algorithms, JSON Web Encryption, JSON Web Key, and JSON Web Signature, have all been recently updated based on discussion at IETF84 and are progressing towards Working Group Last Call (WGLC). Additional drafts under consideration include drafts on serialization, a JSON notation for private keys, and use cases are all under discussion.

_____________________________________
Authentication/Authorization 
AuthN and AuthZ are key components of any managed identity exchange (above or below the Web) and the work called out here will be used in conjunction with efforts in the W3C, OASIS, and other specifications groups to create solutions for both end users and intermediaries.
_____________________________________

scim (System for Cross-domain Identity Management) WG

This newly chartered working group will standardize methods for creating, reading, searching, modifying, and deleting user identities and identity-related objects across administrative domains, with the goal of simplifying common tasks related to user identity management in services and applications. "The chairs believe that the scim comminity see a need for a version 2.0 that involve more than minor incremental changes from what we have now. In our opinion a design team will help the wg start to converge more quickly." Outputs of the proposed design team and reviews of current drafts will both be on the Atlanta agenda.

(8 November 2012, 1300-1500)

--------------

kitten (Common Authentication Technology Next Generation) WG

The kitten working group develops extensions and improvements to the GSS-API, shepherds specific GSS-API security mechanisms, and provides guidance for any new SASL-related submissions. One new proposed work item is the adoption of the kerberous-iana draft. The group will also look at updates to current drafts. There is also a request for expert review for SAML-EC around naming and keying issues

--------------

wpkops (Web PKI Operations) BoF

There are hundreds of variations on the Web PKI in regular use, and this can be a source of problems for certificate users, certificate holders, and certificate issuers. More consistency in Web security behavior is desirable, and a natural first step is to document current behavior. A working group is proposed for the purpose of documenting the operation of the Web PKI. The BoF is intended to gauge support for the proposal and confirm the availability of sufficient resources to complete the work.

(5 November 2012, 1520-1720)

--------------

certrans (Certificate Transparency) BoF

This non-WG forming BoF will discuss plans to specify mechanisms and techniques that allow Internet applications to monitor and verify the issuance of public X.509 certificates such that all issued certificates are available to applications, and each certificate seen by an application can be efficiently shown to be in the log of issued certificates. Furthermore, it should be possible to cryptographically verify the correct operation of the log.

httpauth (Common Authentication Technology Next Generation) WG

This WG formation BoF will discuss a charter that includes developing a set of informational or experimental RFCs for HTTP user authentication schemes that could, following experimentation, be widely adopted as standards-track schemes for HTTP user authentication.

Agenda: N/A

(7 November 2012, 1300-1430)

--------------

oauth (Web Authorization Protocol) WG

The Open Authentication Protocol is a mechanism that allows a user to give third-party web sites or applications access to protected resources without providing them access to their long term credentials or resources. The oauth WG was chartered to update and improve the security mechanisms in the original oauth protocol. With the core protocol work now finished the group will take up recent drafts and continue to aling efforts with the JOSE WG.

abfab (Application Bridging for Federated Access Beyond web) WG

This working group will specify a federated identity mechanism for use by other Internet protocols not based on HTML/HTTP, such as for instance IMAP, XMPP, SSH and NFS. The design will combine existing protocols, specifically the Extensible Authentication Protocol (EAP - RFC 3748), Authentication, Authorization and Account Protocols (RADIUS - RFC 2865 and Diameter - RFC 3588), and the Security Assertion Markup Language (SAML). The core architecture document is nearing completion and there are several recent drafts that will be considered in Atlanta.

(5 November 2012, 1300-1500)

_____________________________________
Infrastructure/Support
Internet infrastructure -- from managed resources to collaborative efforts such as routing -- continues to evolve to meet current needs. Of particular interest this time around are ongoing efforts to secure the routing infrastructure (SIDR) and develop an internationalized successor to whois for accessing information associated with resources.
_____________________________________

karp (Keying and Authentication for Routing Protocols) WG

The karp WG is continuing to focus on improving the state of authentication in all the Internet routing protocols. Many routing protocol deployments, if they use authentication at all, are using older (possibly deprecated) cryptographic algorithms and are missing some modern security mechanisms, like replay protection, algorithm agility, or key rollover. In addition, the issue of key management is a major stumbling block to deployment. The karp WG is working to address these requirements in a number of IETF routing protocols. The design guide has been published as RFC 6518, and several documents including the threat requirements document, an ospf analysis, and an analysis of BGP, LDP, PCEP and MSDP are currently under review by the IESG. Work is expected to continue at this meeting on an operations model, several analysis drafts, and a discussion of a database of long-lived symmetric cryptographic keys.

--------------

irs (Interface to the Routing System) BoF

Routers that form the Internet's routing infrastructure maintain state at various layers of detail and function, including information about the state of the network, policy, etc. This information that may be required for applications to understand the network, verify that programmed state is installed in the forwarding plane, measure the behavior of various flows, and understand the existing configuration and state of the router.

The Interface to the Routing System (IRS) provides a common, standard, read / write interface to allow access to the information and state that enable the routing components of routing elements.

This BoF is to determine focus and support for work within the IETF to specify abstract data information models, specific data models, and protocols to operate the IRS. The BoF does not assume that new data modeling languages or protocols will be required - that decision is expected to form part of the analysis carried out by a working group if one is formed.\

--------------

sidr (Secure Inter-Domain Routing) WG

The SIDR WG is focusing on securing inter-domain routing. The overall architecture is based on a Resource PKI (RPKI) which adds an authentication framework to BGP requiring a certificate management infrastructure. This is a key technology for improving trust in the routing infrastructure.

In its current phase the group is working on the BGPSEC requirements and protocol.

The group had an interim meetings focusing on the protocol as well as handling of some operational cases, like AS migration.

(9 November 2012, 0900-1130)

--------------

weirds (Web Extensible Internet Registration Data Service) WG

Internet registries for both number resources and names have historically maintained a lookup service to permit public access to some portion of the registry database.  Most registries offer the service via WHOIS (RFC 3912), with additional services being offered via world wide web pages, bulk downloads, and other services, such as RPSL (RFC 2622).

The existing standards and related service miss some important features: internationalization, standard data model, differential service.

The weirds WG aims at determining the general needs of such a service, and standardize a single data framework. The framework shall be for data to be delivered via a RESTful data service using HTTP (optionally using TLS), and may use standard features of HTTP to support differential service levels to different classes of user.

Working group tries to work towards a unified (Names and Numbers) protocol in one set of documents. This will be the second face-to-face meeting.

_____________________________________
IPv6
The Internet relies on a single addressing framework in order to have global reach and integrity. IPv4 address space is insufficient for today's Internet, and IPv6 has been developed as its successor. While the standard for IPv6 has long-since been finished, there are ongoing discussions of IPv6 operational issues and management, as well as possible uses in home networks and very large scale networks (of small scale devices).
_____________________________________

v6ops (IPv6 Operations) WG

The v6ops WG continues to be active in describing operational considerations of IPv6 deployment. A couple of interesting drafts that are being discussed by the working group apply in particular to IPv6 on mobile networks:

https://datatracker.ietf.org/doc/draft-binet-v6ops-cellular-host-reqs-rfc3316update/
http://tools.ietf.org/html/draft-byrne-v6ops-64share-03

Both have generated a lot of comment and it will be interesting to see how they proceed.

Charter: https://datatracker.ietf.org/wg/v6ops/charter/
(8 November 2012, 1300-1500; 1510-1710)

--------------

6renum (IPv6 Site Renumbering) WG

The 6renum WG is chartered to perform an analysis of IPv6 site renumbering. If the analysis leads to conclusions that are also applicable to IPv4 that will be an advantage, but it is not an objective of the WG to make its outputs more widely available than IPv6. Similarly the WG is targeting enterprise networks, but the analysis may also be applicable to SOHO or other (e.g. ad-hoc) scenarios.

The working group has issued last calls on each of its 3 working group documents:

http://tools.ietf.org/wg/6renum/draft-ietf-6renum-enterprise/
http://tools.ietf.org/wg/6renum/draft-ietf-6renum-gap-analysis/
http://tools.ietf.org/wg/6renum/draft-ietf-6renum-static-problem/

An iteration of the static problem draft has been made based on WGLC but revisions have not been published on the other two. Presumably any final comments will be discussed on these documents.

Agenda: https://datatracker.ietf.org/meeting/84/agenda/6renum/
Charter: https://datatracker.ietf.org/doc/charter-ietf-6renum/
(8 November 2012, 1730-1830)

--------------

6man (IPv6 Maintenance) WG

The 6man Working Group is charged with the maintenance, upkeep  and advancement of the IPv6 protocol specifications and addressing architecture, which is especially relevant as IPv6 begins to be deployed around the world at scale this year. Reflective of that, the 6man working group has 14 working group documents currently being considered. These are likely to be discussed in Vancouver, as well as some cross items with the 6lowmpan (v6 for low power networks) WG, which is not meeting at IETF 84.

Charter: https://datatracker.ietf.org/doc/charter-ietf-6man/
(5 November 2012, 0900-1130)

--------------

sunset4 (Sunsetting IPv4) WG
sunset4 is a new working group in the Internet Area. In short the formation of the working group is an acknowledgement that the Internet is still largely IPv4, but in the presence of address exhaustion it cannot continue to be the Internet that we know today. The Internet will transition to IPv6 but there will be an interval where the Internet's performance degrades as more coping mechanisms are adopted and before a complete transition to IPv6. This working group hopes to develop techniques to mitigate some of that pain. The immediate activity is to evaluate various CGN (carrier-grade NAT proposals) and determine whether there is a work item around CGN that functions as a suitable IPv4 sunsetting mechanism.

As a result of discussion at IETF 85, the gap analysis document has been made a working group document:

http://tools.ietf.org/wg/sunset4/draft-ietf-sunset4-gapanalysis/

There has been little activity on the mailing list since IETF 85.

Charter: https://datatracker.ietf.org/doc/charter-ietf-sunset4/
(5 November 2012, 15200-1720)

_____________________________________
Bandwidth
The public policy world is full of discussions of appropriate (and inappropriate) management of bandwidth in the face of growing network usage. The IETF and IRTF have a number of efforts underway to explore and address more sophisticated ways to make use of available bandwidth, and otherwise get content to where it needs to be, efficiently.
_____________________________________

rmcat (RTP Media Congestion Avoidance Techniques) WG

This is the first face-to-face meeting of this newly-chartered working group. Today's Internet traffic includes interactive real-time media, which is often carried via sets of flows using RTP over UDP. There is no generally accepted congestion control mechanism for this kind of data flow. With the deployment of applications using the RTCWEB protocol suite, the number of such flows is likely to increase, especially non-fixed-rate flows such as video or adaptive audio. There is therefore some urgency in specifying one or more congestion control mechanisms that can find general acceptance.
