KMIP Server to Client Communication

Hi,

 

I have gone through 
Server to Client Communication requests Notify and Put.

 

As the Spec 
document says " These operations are used to send Managed Cryptographic 
objects directly to clients without a specific request from client" Line 
no:1439.

 

I have the following 
doubts: 

 

        [1] Why these operations are 
necessary since , Client requests (for get attributes) are answered by the 
server.

    

        [2] What happens when client 
is not available when the server sends the Notify/PUT requests. How will the 
server know that client is available. 

 

        
[3] Will client listen on some port so that server can 
send Notify/Put requests.

 

Thanks for the 
updated Use cases document kmip-usecases-1.0-cd-09.doc.

 

In the Use 
cases document it would be helpful if any use cases is mentioned on how 
the multiple attribute instances are possible and Notify/Put 
requests.

 

 

Thanks in 
advance.
