I propose changed and additional text for the LISP WG charter in response to two types of concern: 1 - LISP's name and claim to implementing true Loc/Id separation is problematic, in that other systems such as HIP implement truly separate Locator and Identifier addressing systems (AKA namespaces) while LISP does not. [1] [2] 2 - That the charter should be unambiguous for readers who know nothing about the RRG, LISP etc. and should provide greater clarity about the nature of LISP's "separation". This is especially important considering the false claims made in some LISP I-Ds, presentations and mailing list messages [3] that LISP involves separate namespaces for Locators and Identifiers. - Robin Replace the first 2 sentences of paragraph 3 with the following text (perhaps as one or two paragraphs, rather than the three below) and leave the remaining sentences as a separate paragraph. This new text also explicitly states that EID space is for end-user networks and lists the benefits it provides in a scalable manner. LISP supports the separation of the Internet address space (IPv4 or IPv6) into multiple regions, each of which contains only EIDs or RLOCs. EID addresses are intended to be attractive for end-user networks and to enable the provision of multihoming, portability of the EID addresses between ISPs and inbound traffic engineering to large numbers of these networks in a scalable manner. LISP Ingress Tunnel Routers (ITRs) handle packets addressed to EID regions of the address space via global "map-and-encap" system (RFC 1955) in which a mapping system is used to determine the RLOC address of an Egress Tunnel Router (ETR) to which the packet will be tunneled. The ETR decapsulates the packet and forwards it to the destination network. Hosts and conventional routers make no distinction between addresses in the EID or RLOC regions of the address space. No separate namespaces are created. While it may be possible to use an IPv4 RLOC to tunnel a packet addressed to an IPv6 EID address or vice-versa, IPv4(6) RLOCs and EIDs share the same IPv4(6) namespace. Optionally, at this point, add a mention of HIP as involving separate namespaces for Locator and Identifier. I also propose modifying the last sentence of para 1 to include mention of the proper term which covers LISP, APT, Ivip, TRRP and Six/One Router: "core-edge separation schemes" [4]: In general, these proposals are core-edge separation schemes and were initially known by the term "Locator/Identifier separation".
