Re: [Mipshop] Re: [16NG] FW: Call for Review on FMIP6 over IEEE 802.16e Networks

Hi, Frank & Daniel.

RFC4068 describes fast HO procedure based on prediction, including NCoA formulation in advance.
However, how to allocate the prefix to MN in NAR (before actual HO) is out of scope in this document
as mentioned in Section 4. 

"The method by which Access Routers exchange information about their neighbors, and thereby allow 
  construction of Proxy Router  Advertisements with information about neighboring subnets is outside
  the scope of this document."

Furthermore, the problem you mentioned in draft-xia-mipshop-fmip-ptp-00 is not limited only to 802.16 networks
but happens all networks which have point-to-point link such as 3GPP2.
I think that it is proper to handle this problem separately.

Thanks for your opinion.

- Regards, 
Heejin

Title  : [Mipshop] Re: [16NG] FW: Call for Review on FMIP6 over IEEE 802.16e	Networks

Hi Daniel

Here is my two cents.

The draft is based on RFC4068, and point-to-point link model is also recommended .
RFC4068 is based on shared link model, and is not applicable for point-to-point link model without modification.
So,  there are some basic conflicts in the draft.

Formulation of  a prospective NCoA  is a main idea of  RFC4068. 
But in Point-to-Point link model, it is impossible to formulate the NCoA 
according to  RFC4068 because there is no proper prefix.

Frank
