Motivation

• MOBIKE has to maintain an address list for all available interfaces

• Many events for changing the address set are out of scope of MOBIKE,e.g., IEEE 802.21 Media Independent Handover (MIH)

• These information have to be combined with higher layer information

Making Information available

to various protocols

Page 4: Application Programming Interface to a Trigger Database for MOBIKE

Features

• Define an API to insert these information (so called triggers) into a DB

• Triggers can be provided to MOBIKE and other higher layer protocols

• Offered services are quite similar to MIH,but can be extended for other protocols

• PF_TRIGGER IF is analogue to PF_KEY

(based on BSD routing socket API)

Note: Please do not misunderstand the term „database“.

We solicit input for better terminology here.

Conclusion

• This is an attempt to define an API to make mobility related information available.

• Please let us know if you think that this work is useful.

• Code might be available in the near future.
