The LISP Mapping System
In the Locator/Identifier Separation Protocol the network elements (routers) are responsible for looking up the mapping between end-point-identifiers (EID) and route locators (RLOC) and this process is invisible to the Internet end-hosts. The mappings are stored in a distributed database called the mapping system, which responds to the lookup queries. The LISP beta network initially used a BGP-based mapping system called LISP ALternative Topology (LISP+ALT), but this has now been replaced by a DNS-like indexing system called DDT inspired from LISP-TREE. The protocol design made it easy to plug in a new mapping system, when a different design proved to have benefits. Some proposals have already emerged and have been compared.

Famous quotes containing the words lisp and/or system:
“Taught me my alphabet to say,
To lisp my very earliest word,”
—Edgar Allan Poe (1809–1849)
“I have no concern with any economic criticisms of the communist system; I cannot enquire into whether the abolition of private property is expedient or advantageous. But I am able to recognize that the psychological premises on which the system is based are an untenable illusion. In abolishing private property we deprive the human love of aggression of one of its instruments ... but we have in no way altered the differences in power and influence which are misused by aggressiveness.”
—Sigmund Freud (1856–1939)
