  2. Purpose of this draft • Kind of update of draft-montavont-mobileip-multihoming-pb-statement-00 • Focus on • scenarios of multihoming • Goals/Benefits of multihoming • Generic issues • Not linked to any solution/working group • Not linked to any type of node (apply for fixed/mobile hosts and routers)

  3. Contents of the I-D • Definition of multihoming • Goals/benefits proposition • Real-life scenarios • Rough analysis of the benefits

  4. Goals and benefits proposition • Ubiquitous Access: anywhere and anytime • Redundancy/Fault-Recovery • Load Sharing: share load in the network • Load Balancing: share load between interfaces • Bi-casting: n-cast the traffic to multiple addresses of the node • Preference Settings: allow the user/application/ISP to set preferences on interfaces/addresses

  5. Real-life scenario • Exemple 4: Ubiquitous Access, Load Balancing, Preference Setting • Downloads medical records over satellite link (Faster bit rate, Longer traversal delay) • VC with the specialist over wide area cellular link (best for realtime at the moment)

  6. Rough Analysis • Propose to split multihoming cases: • One interface (multiple prefixes) • No ubiquitous access • No load balancing • Recovery on one prefix failure only • Several interfaces  Give the hints to evaluate a multihoming solution

  7. Future… • Is there any interest in this work ? • No WG designed to take this work… • Is it material for a new BOF ?
