A Decent LISP Mapping System (LISP-Decent)
draft-farinacci-lisp-decent-06
Abstract
This draft describes how the LISP mapping system designed to be
distributed for scale can also be decentralized for management and
trust.

1. Introduction
The LISP architecture and protocols [RFC6830] introduces two new
numbering spaces, Endpoint Identifiers (EIDs) and Routing Locators
(RLOCs) which is intended to provide overlay network functionality.
To map from EID to a set or RLOCs, a control-plane mapping system are
used [RFC6836] [RFC8111]. These mapping systems are distributed in
nature in their deployment for scalability but are centrally managed
by a third- party entity, namely a Mapping System Provider (MSP).
The entities that use the mapping system, such as data-plane xTRs,
depend on and trust the MSP. They do not participate in the mapping
system other than to register and retrieve information to/from the
mapping system [RFC6833].
