Abstract
Current NEMO enabled home network technology [1] does not support any kind
of inbuilt Quality of Service function. In case of various home network
situations, some of prioritized requests are supposed to be occurred under
NEMO environment. This memo suggests additional processes for basis of
priority enabled home network under NEMO environment.

INTERNET-DRAFT QoS Negotiation MO Headers for NEMO Home Network Model, 2006
1. Introduction
Home Network technology connects all devices into one network in one¡¯s
house and provides accessibility of whole devices in the network through
the internet by common method such as home network middleware. Recently,
merging NEMO technology and home networking is perceived as a hot issue
of IETF and new model related to it was selected as one of the drafts in
IETF WG. Accessing the device in Home Network from remote location is
simply possible due to Mobile IP [2] or NEMO technique that can be easily
applied to Home Network. However, in some specific cases such as requiring
communication priorities between MR and HA like users want to send an
urgent print job with receiving VoD data from their home network, current
NEMO basic support architecture [3] can not arrange all kinds of the
communication into descendant or ascendant order.
In this document, we propose two Mobility Option headers [2] to support
priority enabled transmission between MR and HA on NEMO enabled home
network, especially, NEMO extended Home Network Model. Our approach
provides an basis for the priority negotiation process of further complex
Quality of Service processes
2. Terminology
The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL"
in this document are to be interpreted as described in RFC 2119.

3. Extensions
We defined two new Mobility Option headers to exchange priority information
between a MR and its respective HA. At first, priority requesters like
MNNs [4] behind the MR or devices behind the HA will send the information.
if the MR or the HA receives this information, they must send the signal
for negotiation each other. after the negotiation, all kind of traffic
between the MR and the HA can be arranged by themselves. this signal is
the Mobility Option header carried by Mobility Headers in Mobile IPv6.
must exchange the priority level and the requestor¡¯s address,
(1) Priority Negotiation Request Mobility Option
- Contains the priority and the address information for the Destination
- Priority values : 1 (lowest) ~ 10 (highest)

(2) Priority Negotiation Reply Mobility Option
- Contains the return value for the creation

@@@@@@ Priority Request & Reply
<Fig. 1> Multicast Tree when MR starts up
If the users would receive their data more quickly from designated
device when they locate behind the MR far from the home network, they
can request the priority level to the MR through their system. This
means that one¡¯s equipments such as PDA, Notebook, etc, send the
request to the MR. If the MR and the HA, in the fig 1, received a request
for a priority from their ingress network [5], they initiate the MO header
for the negotiation signal and send it to their respective MR or HA.
Afterwards, they receives the result of the negotiation.
5. Conclusion
In this memo, we suggests two newly defined Mobility Option headers for
prioity negotiation on home network enabled NEMO system. Using these
Mobility Options, all communications can be separated into home network
communications and normal internet communications. That means some
urgent traffic can be sent to the destination prior to the others and
normal outgoing/incoming traffic is not affected by our scheme.
This study is a work in progress and need to be improved by any
other individual or commercial issues. Specially, this work can be
adopted on Next Generation Network's Killer Application such as
Mobile Video on Demand, etc. We will add security issue such as
Priroiry Negotiation Mechanism, etc. And also encourage people who
are interested in this work to contribute this work.
