RE: [ws-rx] NEW ISSUE - No indication of how to process NACKs in normal case
Title: Message

 

Hi 
Doug,

 

I went 
back and forth on that one myself for a little while. I prefer MUST too, but 
there appeared to be some push back on this during the initial discussion so I 
stuck with SHOULD.  Your rationale makes sense to me though and I would be 
fine (even happy) to use MUST.  Let's see what the group thinks on the call 
on Thursday.

 

Cheers,
Steve

Steve, 
  
  +1 - although I'd prefer it to be a 
  MUST to be consistent with the text for AckRequested - but since its really up 
  to the RMS to determine when to do it anyway its not a huge thing. 
  
thanks

            [ws-rx] NEW ISSUE - No 
              indication of how to process NACKs in normal 
        case

        
          
          

            
            

  
All, 
  
Here's a description of the new issue I wanted to 
  raise from the discussion of the related issue i005 [1].   
  
Title: Processing model of NACKs 
  
Description: Although it is assumed that a NACK 
  will trigger retransmission of a given message from the source to the 
  destination there is no wording in the current version of the spec that 
  describes this feature adequately. 
  
Justification: This will clarify to implementers 
  the spriit of the spec by spelling out in more concrete terms what is 
  currently only implied. 
  
Target: Core 
  
Type: Design 
  
Proposal: 
  
Add the following to the spec directly before the 
  text that is incorporated as a resolution to i005: 
  
Upon the receipt of a Nack, an RM Source SHOULD 
  retransmit the message identified by the Nack as soon as possible. 
  

  
Cheers,
Steve
