The first part of the teleconference was at 9:30-10:30 Central Daylight Time on Friday May 22.
The second part of the teleconference was at 9:30-10:30 Central Daylight Time on Wednesday May 27.

Attendance: Seil Jon, Carlos Bernardos, Fred Templin, Jong-Hyouk Lee, Anthony Chan

Seil presented using the slides at:

Different cases are described based on different configurations of the functions defined in RFC7429.

Carlos commented that Anchoring Function as defined in RFC7429 is only describing one of the functions of a mobility anchor in the control plane. For example in MIP, the mobility anchor also has data plane functions. Suggest discussions on the functions of anchor.

Fred suggested to generalize case #3 into 2 cases for which LM may be either centralized or distributed. The case with distributed LM is consistent with AERO.

Discussions on the anchor functions were made.

Anthony discussed that there are different functions of the anchor in different proposed solutions. What are common among them seems to be on allocation of IP prefixes and route advertisement.

Seil suggests to split the AF definition into control plane: AF-CP and data plane: AF-DP.
Jong-Hyouk suggests text for such changes.
Here, AF-CP are the functions of Control Plane anchor, whereas the AF-DP are the functions of Data Plane anchor. The name given to the functions of prefix allocation and router advertisement is then AF-CP.

Carlos commented that anchoring should be a data plane concept, while control plane functions are making it to happen.

Seil asked whether to change the name to address management.

Before we can find a suitable name, it may be possible to simply describe IP address anchoring as in slide #5 in the attached file.
