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.

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.

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) 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | QoS Value | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | IPv6 Address for the Destination (128 bit) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Options ...

Operation Flow Fig. 1 shows how network components interact in NEMO extended home network for exchanging and transmitting the priority. _________________________ | | | | | Internet | | |______ |________________________| | __|__ __|__ | | | | | HR | Home Router | AR | Access Router |____|@@@@@@@@@@@@@@@ |____| home ______|_____________ @ _____|_____ link __|__ __|__ * @ __|__ | | | | * @@@@@@@@@@@@@| | | Dev | | Dev | *******************>| MR | Mobile Router |__A__| |__B__| |_____| ____|__________ __|__ __|__ | | | | | Dev | | Dev | |__C__| |__D__| *****> Handover @@@@@@ Priority Request & Reply 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.
