Hi Akbar,

About draft-rahman-core-sleepy-05 Enhanced Sleepy Node Support for CoAP, I have a question. 

Defining Sleep Para to tackle sleep nodes in CoRE networks is an essential work and important. 

By the Figure 3: Prototype Configuration,
you propose to add RD Sleep Para into proxy (CoAP Reverse Proxy). 

Is it possible to transfer Sleep Para into CoAP Client? 
It is the CoAP Client to intial each CoAP request,  
and the CoAP Client may get the infomations about the resources from the ACK of the first access, if possible. 

With this knowledge, the CoAP client could choose the adquate chance to send request, 
and estimate the duration to wait for response.  


Regards,
