18. m32289 DASH sessions arbitration driven by a DANE

Summary:

• 
  It is proposed to provide the following information to a DANE:
  
  • 
    the capacity of a given network link
    
  • 
    client session status from the DASH client to DANE
    
  • 
    DANE should be informed of general quality requirements/policies to be able to determine appropriate network resources allocations.
    
  • 
    Based on this information it is proposed that the client is controlled by traffic management in the DANE.
    
• 
  It is recommended that:
  
  • 
    Allow DANE to be informed of networking conditions by other elements.
    
  • 
    Allows DANE to communicate to other DANE.
    
  • 
    Allow DANE to be directly informed of session status/details from the clients.
    
  • 
    Allow DANE to be configured with profiles/policies regarding the rules for how to manage overall quality of multiple sessions.
    
  • 
    Relation to existing metrics for the DASH client to DANE session information.
    

Recommendation:

1. 
   Include and review the proposed DASH metric along with other proposals.
   
2. 
   For now, DANE to DANE is not priority to address and therefore is not currently included in CE scope.
