Introduction

Introduction

  • Key idea

    • To provide MIPv6 home information through DHCPv6 in the access network

  • Updated from draft-jang-dhc-haopt-02.txt

  • Changes

    • Extended to include not only home subnet prefix and HA address but also home address of MN based on WG feedbacks and WiMAX=m spd.

  • Specific vendor option for MIPv4 already exists.

    • RFC2132 (DHCP Options and BOOTP Vendor Extensions) : Option 68 for HA info.


New dhcpv6 option 1 3

New DHCPv6 Option (1/3)

  • Introduce two options to for delivery of home network information in visited network

    • Home Network Identifier (HNId) option

    • Home Network Information (HNInf) option


New dhcpv6 option 2 3

New DHCPv6 Option (2/3)

  • Home Network Identifier (HNId) option

    • Option-code : OPTION_HNId (TBD)

    • id-type

      0 Local (visited) domain

      • Network realm

  • ‘A’ flag

    A flag to specify whether the client requests a home address or not.


New dhcpv6 option 3 3

New DHCPv6 Option (3/3)

  • Home Network Information (HNInf) option

    • Option-code : OPTION_HNInf (TBD)

    • info-type

      0 Home subnet prefix

      1 HA’s complete IPv6 address

      • HA’s FQDN

      • IPv6 Home address

There can be multiple information


Proposed procedure 1

Proposed Procedure (1)

Visited network

Home network

DHCP server

  • Dynamic HA discovery

  • HoA is preconfigured Get home subnet prefix

HAs

  • Home registration

MN


Proposed procedure 2

Proposed Procedure (2)

Visited network

Home network

DNS server

DHCP server

  • DNS resolution

  • Get HoA & HA’s FQDN

HAs

  • Home registration

MN


Proposed procedure 3

Proposed Procedure (3)

Visited network

DHCP server

  • Get HoA & HA address directly

HAs

  • Home registration

MN


Specific operation

Specific Operation

Visited network

  • Search the proper corresponding info. based on HNId

*@ kt.co.kr – a::b

*@ samsung.com - c::d

*@ sk.co.kr - e::f

DHCPserver

Home network

  • 1. Send DHCPv6 information-request msg.

    • DHCP option request option

    • HNId option with ‘A’=1

    • [samsung.com]

  • 3. Send DHCPv6 reply for CoA

    • HNInf option with HA address [c::d] & HoA

HAs

c::d

  • Home Registration

MN

Applications

  • In integrated bootstrapping scenarios

    • draft-ietf-mip6-bootstrapping-integrated-dhc-01.txt

  • Stage-3 CSN Anchored Mobility in WiMAX

    • 060215-CSN-Anchored-MM-stage-3

  • MIP6 enhancement in 3GPP2

    • X31-20060522-021


Conclusion

Conclusion

  • DHCP is an efficient and convenient way to provide home network information since

    • Widely deployed networks in real networks

    • Allows an MN to discover not only IP addresses but also various the capabilities & configuration parameters through stateless DHCP

  • This draft does not suggest bootstrapping solution but delivery mechanism of home network parameters in the access network.

    • This proposal can be applied for other use such as local HA(MAP) discovery

  • We hope this proposal is adopted as a WG document.
