Required/Missing Technologies in Nautilus

Introduction

The purpose of this document is to arrange the required/missing technologies that we, Nautilus6 WG assumed. We think that there are omissions or mistakes in these, are pleased if you point out!

We had a cross meeting between KAME/USAGI/Nautilus6 WG April 28, 2003 [NautilusLog]. At this meeting, we discussed to clarify the technologies to achieve all-IPv6 world. This document is basically based on this discussion.

Autoconfiguration

• Service discovery
  • nearest DNS server (DNS discovery) [DNSDISC]
• DNS registration(dynamic DNS update?) [DYNDNS]
• Address configuration(stateless enough ? statefull is necessary ?) [DHCPV6]
• Home Prefix delegation(depends on scenario?)
• Detects authentication mechanism depends on ISP/networks. (pana [PANA] is one of solutions)

Seamless Roaming

• Access Control when roaming
  • ac for mobile host with access points/routers
  • ac for mobile network with access points/routers or local servers
  • authorization protocol
  • accounting protocol
• What kind of technologies do we need ?
  • DIAMETER? [DIAMETER]
  • how long does it take? No estimation, because no implementation
• Authentication should be provided on Layer2 or/and Layer 3?
  • Need more discussion.
• pana ? ppp? eap ? etc ?

Security : IPsec / Key exchange

• Mobile IPv6 needs IPsec between HA and MN. [MIP6] [MIP6HAIPSEC]
• IPSec
  • implementation almost done
  • no missing piece?
  • API?
  • Policy Management API (PF_POLICY) [SAKANE] [IPSP]
• IKEv2 ?? (needs certificate) [IKEV2]
• Key exchange
  • end-to-end key exchange protocol
  • IKE is the consensus, but only OK to VPN
    IKE is used both for mobility and fixed.
    There is no alternative??
    Current IKE is too strict in our feeling.
    
  • ad-hoc key exchange protocol(kobayakawa protocol?) [KOBAYAKAWA]
    because IKE is too complex for most work
  • API needed?
• Certificate
  • Collaboration with MOCA WG?
  • PKI

Performance Issue

At the second phase, we will involve some application. Then the performance requirement may be appeared.

• Fast-handoff
• bandwidth selection?
• seamless

Multi-Homing

It's required to solve multi-home in Mobile enviroment like automobile, because there is a requirement to use multiple interface/routers [IITS].

• what particular protocols are needed (missing and existing) ?
  • I/F selection, tools to select best access mode
• Study multi-homing issues [JULIEN]

Disconnected Operation

Mobile node does not have continuous wireless connectivity. In some period, mobile node can connected to the network with one (or more than one) link(s). However, in some other period, mobile node has "no" link to connect to the network. Mobile node will be re-connected with the same or differen link, afterward. During this operaion, the mobile node sysem would be suspended (or not be suspended). This is just a simple operation, that we currently working with. With the "current" system, the TCP/UDP connection must be terminated, when the connectivity is lost (for long time) or the system is suspended. With some applications (e.g., internet radio application), the session could be successfully resumed. But, it is treaed in application level, rather than IP level. Many people would say that this is not mobile environment, but including the other aspects. However, this is what we experience now, in the case of node mobility.

• Need more discussion.

Applications for demonstrations

• mobility-related applis
• non mobility-related applis
• Personal Area Networks
• Videoconf
• Multicast applis
• IITS applis [IITS]

Optional(later, once remaining is done)

• Multicast (IGMP, XCAST)
• Ad-hoc networking
• QoS: what are the existing protocols, what cloud be used?
• IPv6-IPv6 interoperability issues
• IPv4 traversal
