All,
I need clarification on the function of a DEC to request a new request state. Will the PEP remove the installed request-state identified by the client-handle in this DEC and transmit a REQ with a new client-handle or will the subsequent DEC in response to the new REQ override the installed client-state for the specified handle? OR Can it serve as a method for a backup PDC, in the case of failover, to receive client specific information from a PEP in order to provision it in the case the PEP does not transmit a REQ after the CAT...if this can be the case, the Client-Handle cannot be mandatory because the backup PDP would have no knowledge of client-handles? I am trying to find a unique function for the DEC (request for a new request state) and I cannot..I can see a purpose if maybe it is used for COPS-RSVP. In other words, the only reason why a PDP would request a new request state would be if the PDP was aware of a new event occurring related to an external signalling protocol; e.g. a new SIP registration or something which would need to maintain separate states. The bottom line is I do not see any use for it in COPS-PR. Please clarify.
Thank you,
Tina Iliff
