Overview
  • Outline authors opinions of a good approach for
    a DNA
  • Tries to identify a piece of work that is needed
  • Key idea check whether connected to the same or
    a different link

3
DNA Solution Components
  • Link Identifier
  • Explicitly represent the identity of the
    currently attached link
  • RA optimized for DNA
  • with Link ID so that a host can check for link
    change upon a single RA reception
  • with necessary information for a new IP
    configuration so that a host can immediately
    create a new one in case of a link change
  • Quick RA acquisition
  • A way to quickly deliver an RA to a host upon a
    new link-layer connection
  • Optimistic DAD TSLLAO
  • specified in the IPv6 WG

4
DNA Solution Procedure
  • Hint
  • An indication that a link change might have
    occurred
  • Could be a link up from the L2 device driver
  • Receive an RA as fast as possible
  • By sending an RS, or through other means
  • Determine if the same of a different link from
    the RA
  • If a different link, use the information in that
    RA to immediately create a new configuration

5
Work Needed
  • Link Identifier
  • Immediate RA response to RS
  • Optionally RAs that are sent by L2 entity, such
    as AP
  • Optimistic DAD TSLLAO (in IPv6 WG)
  • Figure out when DAD or MLD is triggered in the
    sequence of events

6
Further Steps
  • We ask WG to adopt this draft as a WG item.
