[DNA-BOF] Detecting Network Attachment BoF description (rev 2)

[Gregory Daley <Greg.Daley@eng.monash.edu.au>]

Hi, 

Here is a description of the potential BoF,
with some changes to the goals, to say a few more
things about applicability of DNA.

It is still a bit hand-waving, but the agenda
(when created) will have more details, and will
provide context for some of these goals.

Detecting Network Attachment (DNA) BOF: 
Meeting Description: 

Network Attachment occurs when a host arrives on
a new IP subnet. When attaching to a network, a
host either has current 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. 

  * Determine applicability of network attachment
    detection to providing configuration hints for
    network and upper layer protocols. 

  * Define link layer technologies and network
    topologies 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.
