Description of Working Group:

  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 potentially applicable to
  have a large span, including unicast and multicast overlays at Layer 2
  as well as at Layer 3, encompassing NAT traversal, VPNs, and supporting
  mobility as a general feature, independently of whether it is a mobile
  user or a migrating Virtual Machine (VM). Hence, the LISP technology is
  applicable in both Data Centers and public Internet environments.

  The LISP WG is chartered to continue work on the LISP base protocol and
  produce standard-track documents. In order to produce a coherent set of
  documents, the first (and high priority) work item of the LISP Working
  Group is to develop a standard-track 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.

  In parallel with the previous main work item, the LISP WG will work on
  the items listed below:

    - 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: By extending LISP with new
  multi-protocols support, it becomes necessary to develop the required
  mapping function and control plane extensions to operate LISP
  map-assisted networks (which might include Hierarchical Pull,
  Publish/Subscribe, or Push models, independent mapping systems
  interconnection, security extensions, or alternative transports of the
  LISP control protocol).

    - Mobility: Some LISP deployment scenarios include mobile nodes
  (in mobile environments) or Virtual Machines (VMs in data centers),
  hence, support needs to be provided in order to achieve seamless
  connectivity. This work item may benefit from experience of other
  Working Groups like DMM (Distributed Mobility Management) or NVO3
  (for VM migration).

    - Multicast: Support for overlay multicast by means of replication
  as well as interfacing with existing underlay multicast support. This
  may need discussion with other Working Groups related to multicast
  solutions (e.g. PIM).

    - Data-Plane Encryption: In some scenarios, it may be desirable to
  encrypt LISP encapsulated traffic. In this case, the data-plane
  encryption mechanism itself and support for control-plane security
  material exchange needs to be specified. Any solution proposed in this
  work item has to be reviewed by security experts.

    - NAT-Traversal: Support for NAT-traversal solution in deployments
  where LISP tunnel routers are separated from correspondent tunnel
  routers by a NAT (e.g., LISP mobile node).

    - Models for managing the LISP protocol and deployments that include
  data models, as well as allowing for programmable management interfaces.
  These management methods should be considered for both the data-plane,
  control plane, and mapping system components of standards-track

  Similar to the main work item, documents for these work items will as
  well target standard-track unless the document is of a different
  maturity level (e.g., Informational or Experimental). In the latter
  case, the Working Group will evaluate the maturity level and propose a
  recommended track for the document.

  Collaboration with other working groups, as stated in the different work
  items (e.g., PIM, NVO3, DMM, SFC), is important to ensure to have
  technologies that work smoothly together. The LISP Working Group is
  chartered to work on the LISP technology. It may use technologies
  developed in other working groups, but if it identifies needs for
  extensions or modifications, those extensions and modifications will be
  addressed in the working groups that developed those technologies. The
  LISP Working Group may provide feedback to other working groups based on
  experience gained while using their solutions.
