Title: Analysis of Multihoming in Mobile IPv6


1
Analysis of Multihoming in Mobile IPv6
  • draft-montavont-mobileip-multihoming-pb-statement-
    04.txt
  • N. Montavont (NIST)
  • R. Wakikawa (Keio University)
  • T. Ernst (Keio University)
  • C. Ng (Panasonic Singapore Labs )
  • K. Kuladinithi (University of Bremen )

Structure of the draft
  • Multihoming / MIP6 related terminology
  • Requirements
  • Taxonomy
  • Scenarios
  • Issues
  • IPv6 related issues
  • MIPv6 related issues
  • Implementation related issues

4
Taxonomy
  • x number of active interfaces
  • y number of Home Addresses (HoAs)
  • z number of Care-of Addresses (CoAs)
  • End up with 9 scenarios
  • (1,1,1) is not a multihoming configuration
  • (n,1,1) is a very special case
  • (1,,) and (n,,) are often very close
  • Remove the xnumber of interfaces parameter from
    this taxonomy
  • This taxonomy does not highlight the difference
    between
  • Paths between MN and HAs
  • Paths between HAs and CNs

5
MIPv6 related issues (6.2.1) Binding multiple
CoAs to a given HoA
  • Scenarios (,,n)
  • Provide
  • Redundancy
  • Fault recovery
  • Allows to set policies
  • Load balancing
  • Load sharing

6
MIPv6 related issues (6.2.2) Using a HoA as a CoA
  • Scenarios (,n,)

New binding HoA2 lt-gt HoA1
HA1
HA2
MN
HoA1 becomes the CoA of HoA2
7
MIPv6 related issues (6.2.3) Simultaneous
locationin home and foreign networks
  • Scenarios (,,)

How to bind CoA1 to HoA1, for redundancy purpose
for example?
Visited network
HA1
How to use interface 1, in such a way that if you
change CoA1, your data traffic has not to be
re-initiated
interface 1
interface 2
MN
