The Host Identity Protocol is a signaling protocol which adds another
layer to the Internet model and (optionally) establishes IPsec ESP
SAs to protect subsequent data traffic. HIP is designed to be a
middlebox friendly protocol, it allows the middleboxes (such as NATs
and Firewalls) to participate in the base exchange messages in order
to learn the flow identifier and thereby, relying the data traffic.
Adding authentication and authorization mechanisms can help the
middlebox decide which end hosts are allowed to traverse a firewall.
This can potentially prevent waste of network resources and limit
unwanted traffic. This document gives a problem statement and
requirements for HIP-aware middlebox traversal techniques.

In the body type:

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.
