[dhcwg] Announce: BoF Proposal: Detecting Network Attachment

[Greg Daley <[e-mail]>]

Hi,

There has been some interest in various IETF WGs
regarding what to do when attaching to a network,
and how to distinguish if a host has attached to
a currently configured network or a new one.

I believe that in DHC, this is being pursued for
the purpose of quickly detecting movement upon
joining a link.

There is currently a BoF proposed for IETF57 which
aims to discuss issues uncovered in DHC, Mobile-IP
and Zeroconf WGs.  The hope is that getting together
people from these (and other) groups who are interested
in the problems may lead to a unified approach
to these problems (or at least only one approach each
for IPv4 and IPv6).

Here is the proposed BoF's description:


Detecting Network Attachment (DNA) Proposed BoF Description:

Network Attachment occurs when a host arrives on a new
IP subnet.  When attaching to a network, a host either
already has a valid configuration for this subnet or
must configure addresses.  A host determines whether
it requires additional configuration by Detecting Network
Attachment.

When a host has existing upper layer protocols sessions,
it is important to receive a timely indication that
attachment has occurred.  This may be the case if a host
is connected intermittently, is moving or has urgent data
to transmit upon attachment to a link.

For these nodes, it is also important detect if an acquired
link is new, or has already been visited. This information
may be used to distinguish between events where
configuration must be initiated, or a host already has
valid configuration.

This meeting hopes to providing a forum for those
interested in developing generic attachment detection
technologies for IPv4 and IPv6.

The BOF aims to:

* Describe existing issues encountered in DHC, ZEROCONF
   and Mobileip WGs, which could benefit from work on
   detecting network attachment.

* Define the problem scope, and environments where network
   attachment detection is desirable.

* Determine if sufficient interest exists to form a
   Working Group on this topic.

* Reach consensus on the area of work for a potential WG,
   including which problems are outside scope.
