Or even more infrequent. That’s based on real world service type and 
environment.

 

        It almost seems you're suggesting a service should effectively run a 
separate connection manager for each variant of device/platform/network/solar 
activity/phase of moon/etc.  That doesn't sound very scalable to me.

        Sending at the same rate usually means each end will detect a stale 
connection at roughly the same time.  That's a Good Thing™.

If one side don’t know the frequency of keepalive the other side sending,  how 
does it detect disconnection more quickly? Can’t just  guess  interval the 
other side adopt.

I think it’s better to negotiate a same value.

        As Ben stated, it's an optional feature; if you don't want it, don't 
use it.

        Also, I'm not sure what you mean by "stalled".  XEPs -0124 and -0206 
are DRAFT, updated with implementation experience.  Are you suggesting we 
should progress them to FINAL, or do you have a specific set of problems that 
need immediate attention?
