Re: policy time period condition in diffserv PIB

Hi,

I have some questions on your suggestion of using multiple request-state
feature in COPS-PR and pibIncarnationTable in framework PIB, for activating/de-activating policy rules:

1. In your solution, is there:
    a. one PIB instance for all the policy rules which are active all the time,
         corresponding to the client handle that is used when the PEP connects
         first time?
    b. one PIB instance for each distinct "time-of-day" class instance defined
         in the policy rules?

2. What does activate and de-activate mean for a PIB instance? This does
     not seem to be explained in framework PIB. It also says that there can
     be only one PIB instance active.

Another alternative would be for the PDP to install all policies with only one being active.Then, when the active context should change the PDP would send a Unsolicited DEC (with the Install command and the Handle of the correct "Time-of-day" request-state) and only one instance of the frwkPibIncarnation class with the Active attribute set to True.

The PDP takes care of scheduling the rules and NOT the PEP.
The PDP can send an unsolicited COPS DEC message with 'install' when the scheduling
period starts. Similarly it sends an unsolicited COPS DEC message with 'remove' when
the period ends.

Hi,The draft-ietf-diffserv-pib-03.txt does not seem to contain policy time
period condition as specified in PCIM.How can a PDP push a set of policies and mandate that the policies should be active
only during the Time Period as specified in the policies?( For example certain set policies are to be active between 9:00 to 6:00, how can this time information of the policy be fitted into the PIB ?)Regards,Saurabh Kapoor
