Georgios,
The framework is only at a high level. As we go deeper, granularity will arise.
I thought these mobility management signaling are mainly in the control plane. When you say separation into control path and data path, do you mean the signaling and the data traffic can take different paths?

Hi Anthony,



I have read the draft-chan-dmm-framework-gap-analysis-02.txt.



The DMM framework part description is useful. However, I have a comment!
The current provided DMM framework is not making any distinction between control path and data path related functions/entities.



I think that the DMM framework should provide this distinction, since functions/entities that are supporting the control path may not be collocated with functions/entities that are supporting the data path.



This comment is in my opinion valid for both: (1) mobility routing (MR) function/entity and (2) internetwork location management (LM) function/entity.



This could mean that:



The MR function/entity can be divided in:
MRC (Mobility Routing Control path) function/entity
MRD (Mobility Routing Data path) function/entity



The LM function can be divided in:
LMC (internetwork Location Management Control path) function/entity
LMD (internetwork Location Management Data path) function/entity



Best regards,
Georgios
