Agenda


• IETF Status

• MANET

• AUTOCONF



• MANEMO Status






MANEMO Status?“Unfortunately, MANEMO is still not yet clearly defined and understood by IETF

community.”

“MANEMO may be just another configuration of MANET/AUTOCONF. The answer is still not clear..... “

“It depends on how you can see this MANEMO world in terms of addressing, wireless technology, topology formation, etc. You may approach the MANEMO

problem with existing solutions. However, existing solutions cannot cover whole idea of MANEMO. We believe there are also missing pieces for MANEMO in IETF. What

are the missing pieces?”

draft-wakikawa-manemoarch-00.txt






So...MANEMO Status?

• Non-official meetings at 68th IETF:

• manet-centric vs. non-manet-centric views

• solution-space rather than problem-space

• 69th IETF and beyond?






Recent Contributions

• Understanding the topology & architecture

• draft-wakikawa-manemoarch-00.txt

• Understanding scenarios and deployments

• draft-mccarthy-manemo-configuration-problems-00.txt

• Then, understanding the (potential) solution space.

Conclusion(Or, a personal view)

• MANET/AUTOCONF offers:• architecture: routers + hosts• routers (can) run routing (& other) protocols• management of MANET interface characteristics

• MANEMO deployments • share many MANET characteristics• nesting problems solved MANET-centric• may have additional requirements

• Unified solution preferential.....
