Re: [MEXT] LISP as a solution for some part of the DMM requirement

Dear Charles,

I think the LISP can also be considered as a promising candidate
in the design of DMM solutions. Several works are being progressed
to use or extend the LISP for mobility support, which inlcude LISP-MN draft
and many research papers. Actually, I am also considering how to extend
the LISP scheme in the DMM perspective.

LISP is a network-based ID-LOC separation scheme and thus it may give some
advantages for effective mobility support. On the other hand, it is noted that
the current version of LISP and LISP-MN may need to be more enhanced
in terms of scalability in the mobile environment. For example, one concern of LISP
is that the LISP EIDs may not be aggregated anymore in the mobile networks, since
each mobile node will have its own distinctive EIDs that do not conform the concerned mobile domain.
This may decrease the scaling benefits of original LISP.
We may need to design a new enhanced EID structure to be used for mobile environment.
Nontheless, it is worthwhile to consider LISP as a promisng candidate in the disign of DMM, I think.

By the way, as I already said in this IETF DMM ad hoc meeting, the urgent action item of DMM is
to make one or more introductory I-Ds with WG consensus, which may include
the problem statements and requirements for DMM, use cases/scenarios, and comparison matrix, etc.

Regards,
