  1. Bootstrap Control Function mechanism for Mobile IPv6 Bootstrapdraft-deng-mip6-bootstrap-bcf-00.txt Hui Deng Hitachi (China) Qin Li BeiHang University Chongfeng Xie China Telecom Minghui Wang China Unicom

  2. Problem Statement • I-D: draft-ietf-mip6-bootstrap-ps-01

  3. Motivation - 1 • Focus on Bootstrap for MIPv6 • Authentication for mobility service SHOULD be separated from auth of network access because there will be a general solution for the latter (MSP rather IASP)

  4. Motivation - 2 • HA assignment based on • User Profile • HA Load Balance • Bootstrap Function within MIPv6 protocol • Bootstrap ability in MIPv6 itself • New mobility headers (Init and Ack message)

  5. Proposal • Introduced new network element/function • Bootstrap Control Function (BCF) • BCF • Receive Bootstrap Init Message from MN • With auth-opt, nai-opt, auth-id-opt • Allocate HoA and HA for MN • Respond with Bootstrap Ack Message • With HoA address opt • Inform MN to switch to assigned HA

  6. Solution Visited Network | Home Network | | | +-------+ | | AAA | +-------+ | +-------+ +--------| HA1 | | | | +-------+ | | | | | | +------+ Init | --> +-------+ | +-------+ | MN |<--------|-------->| BCF |---+--------| HA2 | +------+ Ack | <-- +-------+ | +-------+ | | ... | | | | +-------+ | +--------| HAn | | +-------+ Blue color: New control function Red color: defined two new mobility headers

  10. Questions to WG: 1: work item? 2: Is it possible to divide bootstrap solutions into two work items: IASP based and MSP based?
