LISP Single-Hop DHT Mapping Overlay

This draft specifies the LISP Single-Hop Distributed Hash Table Mapping Database (LISP-SHDHT), a distributed mapping database which consists of a set of SHDHT Nodes to provide mappings from LISP Endpoint Identifiers (EIDs) to Routing Locators (RLOCs). EID namespace is dynamically distributed among SHDHT Nodes based on DHT Hash algorithm. Each SHDHT Node is configured with one or more hash spaces which contain multiple EID-prefixes along with RLOCs of corresponding Map Servers.
