RE: [802.21] [Mipshop] Re: Architectural Considerations for Handover InformationServices (was: Re: CARD Discussion Query Discussion)

Hi Michael, 

My read of IETF view is that IETF folks are suggesting that simplicity
should take preference over bandwidth utilization to some extent. For
example, if we can save 5% bandwidth by adding 2x complexity then
perhaps simplicity should get preference over complexity. But as far as
I can say IETF folks are not suggesting performance issue should be
totally ignored in the name of simplicity. Also, from IETF discussion it
appears that TLV encoding is getting preference over XML encoding. 

Regards,
Ajoy

Colleagues,

The folks from the IETF have been saying that the IS consuming more
bandwidth is not a problem, while the IEEE folks are saying bandwidth
and latency are key concerns. We need some meeting of the minds and
implementations/empirical data to help out here.

Best Regards,
Michael

If I remember it right XCAP/XML is used there for maintaining the
address book/buddy list that sort of things. I can imagine that sort of
events only happen at most no more than a few times a day for any given
user and probably only happen when the user is NOT in a call. In
contrast, IS query/response likely will be part of the h/o call flow...
