Joel, Luigi,
thanks for taking a stab at this one.
I think it covers the relevant aspects that I would like to see the WG
to focus on.
As discussed in the use case thread, I would suggest that the draft
should mention a very small set of use cases that we can use to drive
the design decisions. I think that we can possibly cover all of the
protocol aspects you describe if we take the following two use cases:
1) LISP-based programmable L2/L3 VPNs with extensions to support the
following services:
- encryption
- programmatic northbound access to the mapping and to xTR
configuration
- SFC/NFV
- VPN termination on mobile nodes
2) LISP-based programmable L2/L3 VPNs for DC applications
I think these two will give a good scope to the WG work and, without
resorting to more exotic use cases, reinforce the focus on the use of
LISP as an overlay technology.
Thanks,
Fabio

Folks,
in the past weeks (and months) there was a fruitful discussion that took place
on the mailing list (and also in Prague) concerning
the new charter to be adopted by our WG. Thanks for this effort.
Beside this discussion we had proposals from WG members as well as discussion
with our AD about what is practical and reasonable.
Hereafter you can find the result: a draft of the new proposed charter.
This does not mean that discussion is over, rather that we reached a first
consistent milestone for further discussion.
Discussion ideally culminating in our meeting in Japan.
So please have look and send your thoughts and feedback to the mailing list.
Joel and Luigi

The LISP WG has completed the first set of Experimental RFCs
describing the Locator/ID Separation Protocol (LISP). LISP supports
a routing architecture which decouples the routing locators and
identifiers, thus allowing for efficient aggregation of the routing locator
space and providing persistent identifiers in the identifier space.
LISP requires no changes to end-systems or to routers that do not
directly participate in the LISP deployment. LISP aims for an
incrementally deployable protocol. The scope of the LISP
technology is recognized to range from programmable overlays,
at Layer 2 as well as at Layer 3, including NAT traversal, and
supporting mobility as a general feature, independently of whether
it is a mobile user or a migrating VM, hence being applicable in both
Data Centers and public Internet environments.
The LISP WG is chartered to continue work on the LISP base protocol
with the main objective to develop a standard solution based on the
completed Experimental RFCs and the experience gained from early
deployments.
This work will include reviewing the existing set of Experimental RFCs
and doing the necessary enhancements to support a base set of
standards track RFCs. The group will review the current set of Working
Group documents to identify potential standards-track documents and
do the necessary enhancements to support standards-track. It is
recognized that some of the work will continue on the experimental track,
though the group is encouraged to move the documents to standards
track in support of network use, whereas the work previously was
scoped to research studies.
Beside this main focus, the LISP WG may work on the following items:
• NAT-Traversal
• Mobility
• Data-Plane Encryption
• Multicast: Support for overlay multicast by means of replication
as well as interfacing with existing underlay multicast support.
• YANG Data models for management of LISP.
• Multi-protocol support: Specifying the required extensions to support
multi-protocol encapsulation (e.g., L2 or NSH – Network Service
Headers). Rather than developing new encapsulations, the work will
aim at using existing well-established encapsulations or emerging
from other Working Groups such as NVO3 and SFC.
• Alternative Mapping System Design: When extending LISP to support
new protocols,it may be also necessary to develop the related mapping
function extensions to operate LISP map-assisted networks (which
might include Hierarchical Pull, Publish/Subscribe, or Push models
and related security extensions).
