Re: [6lowapp] Proposed charter for 6LoWAPP BOF

Hi Jonathan,

Aggregators are great devices when defined by end customers to meet an
application need.  The trouble comes in when we introduce them for network
layer support in non-obvious places.

I think we should try to find solutions which avoid PEPs and other
aggregation devices in general.  If we find we have to have these devices,
we should work with those responsible for deployment to be sure this maps to
their solution space.

Right.  Then I would ask if you would find it useful/necessary for  
this WG to work on standardizing a service that can effectively  
aggregate LLN devices?

I'm really asking these questions because I don't think it's obvious  
what pieces are necessary.  Even less obvious if we don't have clear- 
cut application targets.
