Title : A common framework for autoconfiguration of stand-alone ad hoc networks

We consider the unique address autoconfiguration problem for stand-
alone ad hoc networks (MANETs). Specifically, we consider two cases.
First, a node without a pre-assigned and valid local address acquires
a new local address and becomes a member of a new or existing MANET.
Second, two or more MANETs merge. In the first case, a mechanism of
IP address generation is needed. We also should have MANET-wide
duplicate address detection (DAD) on newly generated address
(tentative address) for suppressing occurrence of duplicate addresses
for address generation (pre-service DAD). In the second case,
duplicate address may occur as the result of a merger of two formerly
independent networks. We should have DAD on addresses in use for
resolving duplicate addresses and suppressing routing information
contamination due to existence of duplicate addresses (in-service
DAD). To realize pre-service DAD and in-service DAD, we define
autoconfiguration states that are common for both proactive and
reactive routing protocol. Each node exists in one of the
autoconfiguration states at any time. A node, that detects duplicate
address between other nodes, should advertise the detected duplicate
address to all other nodes In the MANET.This is termed "Duplicate
address advertisement" (DAA). The specific DAD and DAA algorithm is
beyond the scope of this document.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.

implementation to automatically retrieve the ASCII version of the
