Re: Fmipv6

Hi Anurag,

 

I don’t understand the need of sending NA before FNA. Also, as Rajeev pointed, the delay (200+ms) which you are saving with the UNA message seems high.

Could you please let me know how you are able to reduce this delay with UNA message.

 

Some points that need to be considered with the introduction of UNA message:

1. In reactive mode, if MN is going to sent FBU immediately after UNA, then there will be packet loss in case of duplicate address. But the same loss won’t be there when we use FNA[FBU] message.
2. with UNA, in case of duplicate address, additional burden at PAR to delete or modify the tunnel that was created based on wrong NCOA (received with FBU send immediately after UNA).

 

Regards,

Mohan

Can you provide some information about your system?
What are the interfaces used, what platform OS? And, how you are able to save on the delay, which seems high BTW.

Thanks,

Dear Rajeev,

Thanks man for converting FNA to UNA in your new draft  &quot;Fast Handovers for Mobile IPv6 draft-ietf-mipshop-fmipv6-rfc4068bis-01.txt". We have implemented Fmip6 for multiple interfaces.  Now we are able to save almost 200+ ms.  which we were wasting on NA for rechable and then FNA.
