For time of day its ok, because policy rules may have temporal conditions attached to them. But, for other external triggers, how would the triggers identify the PEPID and the PIB that will be affected? It is not very clear from the PR draft at least.

Weilin,
Yes, the PDP can detect external events and decide what policy decisions need to be made for what PEP. A simple example is Time of Day. The policy for filter markers may change at 6PM. The PDP implementation has rules to determine which PEP's are affected by the Time of Day event and changes policy accordingly.

Subject: access request initialted by other sources than PEPs in COPS-PR
Hi,
I encountered a problem when reading the COPS-PR. In Section 6(p27), the doc state that there is a case that access requests to the policy server can be initiated by other sources besides the PEPs. I think if the PEP don't initialize the request, the PDP cannot identify the PEP and cannot send the policy decision to PEP. Can anyone give me an explanation? Can this case be handled by COPS?
Thanks
Weilin
