Range of priority levels

Priority: major Milestone:
Component: drmp Version:
Severity: Active WG Document Keywords:


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.
