Re: [Mobopts] Re: [Mip6] Delay Analysis for Handoffs with Mobile IPv6Route Optimization

Mohammed,

it's very good that you point to related work that you did.

Still, I refer to the discussion that Thomas and I had yesterday on the differences between network-assisted mobility (which is what you have experimented with) and end-to-end mobility (which is what our analysis is about).

To be brief: Our work is truly orthogonal.

Further, I should mention that our analysis assumes the use of DNA mechanisms (DNA protocol, CPL, FastRA) to eliminate router-discovery and movement-detection delays during reactive handoffs, Optimistic DAD to get rid of the address-configuration latency, and Media Independent Handover Services (including Information Services) to facilitate proactive handoffs.

Hope this makes things more clear.

Regards,
- Christian
