Internet Society's Rough Guide to IETF 80's Hot Topics 
-----------------------------------------------

IETF 80 in Prague is rapidly approaching (27 March - 1 April). Newcomers' training and technical tutorials take place on Sunday (27 March), with the working group, BoF, and plenary sessions happening during the week.

Once again, the Internet Society is pleased to bring you our regular rough guide to the sessions most relevant to our current work.

We have turned our attention to the following broad categories:

- Common and Open Internet
- Global Addressing
- Security and Stability
- Trust and Identity

Of course, with more than 100 working groups, there are many other important technologies under discussion. So for full details of the IETF 80 agenda, see:

https://datatracker.ietf.org/meeting/80/agenda.html

(All times are local Central European Time, UTC +1)

_____________________________________
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.

behave (Behavior Engineering for Hindrance Avoidance) WG

The behave Working Group creates documents to make NATs function in as deterministic manner as possible. Much of the recent work has been to document the behavior of IPv6/IPv4 protocol and address translation. Items of possible interest include analysis of 64 Translation (draft-penno-behave-64-analysis) and Large-Scale NAT Requirements (draft-ietf-behave-lsn-requirements).

cdni (Content Distribution Network Interconnection) BoF

Content Delivery Networks (CDNs) are widely deployed to improve scalability and performance of content delivery on the Internet. There is currently no standard way to interconnect CDN platforms. This BoF is to discuss the proposed development of IETF standards to facilitate such CDN interconnection. These standards might include protocols for 1) exchange of metadata between CDNs, 2) exchange of transaction logs & monitoring information, 3) exchange of request-routing information, 4) exchange of policies & capabilities, and 5) content management/flushing.

(31 March 2011; 1740-1940)

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

conex (Congestion Exposure) WG

The conex WG is concerned with exposing the congestion on the forward path of a flow to the network elements along that path. The mechanism to be developed by the conex WG will enable the sender to also relay the congestion information back into the network in-band at the IP layer, such that the total level of congestion is visible to all IP devices along the path, from where it could, for example, be provided as input to traffic management. The primary goal of the conex WG is to develop experimental specifications to achieve the above in IPv6 networks.

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

dane (DNS-Based Authentication of Named Entities) WG

The dane WG is chartered to specify mechanisms and techniques that allow Internet applications to establish cryptographically secured communications by using information distributed through DNSSEC for discovering and authenticating public keys which are associated with a service located at a domain name.  Building upon the implementation and deployment of DNSSEC, this work seeks to use the chain of trust established in the DNS to enable on-demand establishment of secure channels for a multiplicity of applications. The technical and business implications of this work are significant.

(30 March 2011; 0900-1130)

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

dnsext (DNS Extensions) WG

The main agenda item for the dnsext WG will be the aliasing work; This work attempts to tackle a set of issues that arises from the desire to treat a set or group of names as "aliases" of each other, "bundled," "variants," or "the same," which is problematic in terms of corresponding behaviour for DNS labels and FQDNs (draft-ietf-dnsext-aliasing-requirements). The second item on the agenda is improvements to DNS Resolvers, for Resiliency, Robustness, and Responsiveness (draft-vixie-dnsext-resimprove).

Charter: http://tools.ietf.org/wg/dnsext/charters
Agenda: http://tools.ietf.org/wg/dnsext/agenda
(28 March 2011, 1510-1610)

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

rtcweb (Real Time Communication on the World Wide Web) BoF

Several proprietary implementations of browser-based real-time communication platforms exist, for example for web conferencing or gaming. These implementations typically require non-standard browser extensions to be installed. This BoF meeting will discuss proposals to standardise this functionality so that this type of application can run in any compatible browser without the need for additional software.

Agenda: http://www.ietf.org/proceedings/80/agenda/rtcweb.html
(29 March 2011; 0900-1130)

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

tictoc (Timing over IP Connection and Transfer of Clock) WG

The tictoc working group is chartered to address next generation network time synchronization requirements. It is looking into enhancements for both the Network Time Protocol (NTP) and the IEEE 1588 Precise Time Protocol (PTP). The work is currently focused on MPLS encapsulations, security requirements, and network management. 

Charter: http://tools.ietf.org/wg/tictoc/charters

tsvarea (Transport Area) Open Meeting

bufferbloat.net is a new project initiated by Jim Gettys to tackle congestion and latency problems created by oversized buffers in the end-to-end path. Jim will present his research and the project's progress during this open area meeting. The problem is well-known to transport experts, but there is renewed energy in tackling it and a focus for activity as a result of Jim's efforts. The meeting will also hear from Google about their SPDY (pronounced "SPeeDY") application-layer protocol for transporting content over the web, designed specifically for minimal latency.

(30 March 2011; 0900-1130)

_____________________________________
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 Networks) WG

The 6lowpan Working Group exists to develop IETF standards for IPv6 over low-power personal area networks. A lot of the work has focused on developing a version of IPv6 neighbor discovery (ND) that is more suited to networks with intermittent and irregular connectivity, where use of the radio resources is limited. Looking for completion of the 6lowpan ND document. There are a number of other proposed areas of work here. This has gained quite a lot of interest in the last year with the proposed use of IPv6 for the Internet of Things.

Charter: https://tools.ietf.org/wg/6lowpan/charters
Agenda: not yet posted
(29 March 2011; 1520-1700)

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

renum (Site Renumbering) BoF

BoF to discuss specific problems with renumbering networks and specific spot techniques to make those less painful. One incentive for the use of NATs in IPv6 is to allow a change in network operator without renumbering the network.  It will be interesting to see whether there is anything useful enough to dis-incent that desire.

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.
_____________________________________

dane (DNS-based Authentication of Named Entities) WG

The dane (formerly keyassure) working group is looking at the use of DNSSEC to facilitate the establishment of cryptographically secure communications for Internet applications. This is a relatively new working group having been chartered after the last IETF meeting. Current drafts address using Secure DNS to Associate Certificates with Domain Names For TLS and S/MIME. 

Charter: http://tools.ietf.org/wg/dane/charters
Agenda: http://tools.ietf.org/wg/dane/agenda

karp (Keying and Authentication for Routing Protocols) WG

The karp WG is focused 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 working group is working to address these requirements in a number of protocols. The foundational documents have stabilized, and this meeting will focus on analysis of BGP, LDP, MSDP, and OSPF along with multicast router key management. 

Charter: http://tools.ietf.org/wg/karp/charters
Agenda: http://tools.ietf.org/wg/karp/agenda
(01 April 2011, 0900-1130)

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

sidr (Secure Inter-Domain Routing) WG

The SIDR WG is focused on securing inter-domain routing. The approach being developed is Resource PKI (RPKI). RPKI adds an authentication framework to BGP. It is going to require a certificate management infrastructure. This is a key technology for improving trust in the routing infrastructure. Initial operational deployments are expected this year. Topics of possible interest include re-chartering to include path validation and discussion of the BGP security requirement
