[RAM] some draft proposed definitions

	Here is a draft proposal for terminology, with the goal
being greater clarity of communication.  This is a starting
point, not an all-inclusive list.

Yours,

Ran

Identifier:	An object that is used only for identification,
		never for forwarding packets or determining location.

ID:		Abbreviation for Identifier.

Locator:	An object that is used only for forwarding packets
		or determining location, never for identification.

Address:	An object that with mixed semantics, where it is
		sometimes used for identity and sometimes used
		for packet forwarding.  Examples include but are
		not limited to IP addresses, which are sometimes
		used to forward packets and sometimes used for
		identity (e.g. in TCP session state).

RLOC:		An object used for forwarding packets
		in the LISP protocols.

Scoped Locator:	A locator that has non-global scope.  Note that
		a scoped locator only has location semantics,
		never identification semantics.

Scoped Identifier:  An identifier with non-global scope.  Note that
		a scoped identifier only has identity semantics,
		never location semantics.

Identity:	A possible property of an object.  Addresses and
		Identifiers are examples of objects that have
		identity semantics.

Location:	A possible property of an object.  Addresses and
		Locators are examples of objects that have
		location semantics.

Identifier/Locator split:	A class of network protocol that
		has no addresses, and only has (pure) identifiers
		and (pure) locators.

Multi-Address split:		A class of network protocol where
		one type of address is used for forwarding in one
		portion of the internetwork and a different type
		of address is used for forwarding in a different
		portion of the internetwork.  Simple NAT is not
		an example of a multi-address split, since the
		same *type* of address (IPv4 xor IPv6) is used
		in all routing domains.
