Re: [Dime] [dime] #92 (drmp): Range of priority levels

I have consulted with a couple of other people here, and we agree that 5 
is probably sufficient  for this.

You typically only need more priority levels when you are dealing with 
resources with long holding times (which includes some of the resources 
ARP is used for).

With regard to the situation where the priority value is not present, 
assigning a "default priority" within the existing levels seems to work 
well .

I have stated previously that I believe 5 levels are adequate, as I do not 
see action on more than that.

#92: Range of priority levels

 The ietf-dime-drmp draft currently mentions 5 levels of priorities which 
appear to be not enough. In 3GPP, levels of priorities are also defined 
outside Diameter with, in particular, sixteen levels in Policy Control for 
 the ARP (Allocation and Retention Priority)information element. So it 
would be better that the DRMP AVP also allow 16 values which is future 
proof and leaves more flexibility on their allocation.
 Another point also addressed in #91 ticket is that the range can contain 
priorities which are higher or lower than the normal priority 
corresponding to the case where the DRMP AVP is not present (existing 
situation); this also drives to consider a larger range of levels with an 
intermediate value corresponding to the normal priority.
