A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : DNA with unmodified routers: Prefix list based approach
Author(s) : J. Choi, E. Nordmark
Filename : draft-jinchoi-dna-cpl-00.txt
Pages : 21
Date : 2004-7-12
Upon establishing a new link-layer connection, a host determines
whether a link change has occurred to examine the validity of its IP
configuration. This draft presents a way to robustly check for link
change without assuming changes to the routers. Each link can be
uniquely identified by the set of prefixes assigned to it. We
propose that, at each attached link, the host generates the complete
prefix list, that is, the prefix list contains all the prefixes on
the link, and when it receives a hint that indicates a possible link
change, it detects the identity of the link by consulting the
existing prefix list. This memo describes how to generate the
complete prefix list and to robustly check for link change even in
the presence of packet losses.

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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
