The Locator/ID Separation Protocol (lisp) WG in the Routing Area of the IETF is undergoing rechartering. The IESG has not made any determination yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg@ietf.org) by 2016-04-18. Locator/ID Separation Protocol (lisp) ----------------------------------------------------------------------- Current status: Active WG Chairs: Joel Halpern <jmh@joelhalpern.com> Luigi Iannone <ggx@gigix.net> Secretaries: Damien Saucez <damien.saucez@gmail.com> Wassim Haddad <Wassim.Haddad@ericsson.com> Assigned Area Director: Deborah Brungard <db3546@att.com> Routing Area Directors: Alia Atlas <akatlas@gmail.com> Alvaro Retana <aretana@cisco.com> Deborah Brungard <db3546@att.com> Mailing list: Address: lisp@ietf.org To subscribe: https://www.ietf.org/mailman/listinfo/lisp Archive: https://mailarchive.ietf.org/arch/browse/lisp/ Charter: https://datatracker.ietf.org/doc/charter-ietf-lisp/ 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 (unless the content of the document itself is of a different type, e.g., informational or experimental). 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 documents. Documents of these work items will as well target standard-track unless the main content of the document itself clearly demands for a different type (e.g., informational or experimental). In the latter case the Working Group needs to determine the proper document class. 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, and only use solutions/technology developed in other working groups. The LISP Working Group may provide feedback to other working groups based on experience gained while using their solutions. Milestones: TBD
