Generally, these topics fall into the following categories:<br><br><span class="Apple-tab-span" style="white-space: pre; "> </span>IPv4/IPv6 Coexistence<br><span class="Apple-tab-span" style="white-space: pre; "> </span>Securing Internet Infrastructure<br><span class="Apple-tab-span" style="white-space: pre; "> </span>Trust and Identity<br><span class="Apple-tab-span" style="white-space: pre; "> </span>Bandwidth Management<br><span class="Apple-tab-span" style="white-space: pre; "> </span>IETF Structure and Process<br><br><br>Remote participation in all meetings will be possible -- see specific meetings listed on <a href="http://tools.ietf.org/agenda/74/">http://tools.ietf.org/agenda/74/</a> for access to audio stream and jabber rooms.

This pertains to IPv6 and continued existence of IPv4 following IPv4 address completion. Some of the other address sharing proposals may be being merged with existing DS-lite proposals. What we are hoping for here is an optimal an address sharing solution as we can envisage combining IPv6 deployment and a reasonable level of end user control.<br><br>Currently scheduled:<br><span class="Apple-tab-span" style="white-space: pre; "> </span>Friday March 27 2009, 09h00-11h30<br>WG Agenda: [Not available]<br>WG webpage: <a href="http://www.ietf.org/html.charters/softwire-charter.html">http://www.ietf.org/html.charters/softwire-charter.html</a><br><br><br>SHARA BOF: Sharing of an IPv4 Address BOF<br>This BOF is concerned with address sharing and all the various proposals for IPv4 address-sharing that have emerged recently. Randy Bush’s overview of the many address-sharing proposals that were around led to this BOF to focus on the topic specifically. This is not a working group forming BOF.

An independent author draft was submitted between IETF72 and IETF73; there was a BOF at IETF73. There is a lot of interest in the 1.0 spec for OAUTH. Since IETF73, there has been work on drafting a charter and a lot of discussion about what should go in it.

In other words, a mechanism that would allow bandwidth intensive applications to scavenge as much free bandwidth as possible without negatively impacting on simultaneously occurring interactive, or inelastic traffic flows.

Documented trial deployments illustrate the potential benefits of this approach.
