Dear LISP WG, This is a new LISP Use Case draft, and this one is centered on how to use LISP for a number of network-based mobility use cases. We¹d like to request comments on this. Terry/Joel, we¹d also like a 5 minute slot at IETF89 to present this use case draft Yves On 14/02/14 18:12, "internet-drafts@ietf.org" <internet-drafts@ietf.org> wrote: > >A new version of I-D, draft-hertoghs-lisp-mobility-use-cases-00.txt >has been successfully submitted by Yves Hertoghs and posted to the >IETF repository. > >Name: draft-hertoghs-lisp-mobility-use-cases >Revision: 00 >Title: End Host Mobility Use Cases for LISP >Document date: 2014-02-14 >Group: Individual Submission >Pages: 17 >URL: >http://www.ietf.org/internet-drafts/draft-hertoghs-lisp-mobility-use-cases >-00.txt >Status: >https://datatracker.ietf.org/doc/draft-hertoghs-lisp-mobility-use-cases/ >Htmlized: >http://tools.ietf.org/html/draft-hertoghs-lisp-mobility-use-cases-00 > > >Abstract: > This memo proposes use cases for LISP in the area of end Host > mobility.
