RE: COPS usage





Mai Trang,

Here is one answer or recommendation to your questions.
1. I would recommend using COPS usage for RSVP.
2. No, it does not conflict.  In fact, you can consider this as an example
of an "external event" which is mentioned in the COPS RFCs.

Subject:	COPS usage

Hi all,

I have a question about the COPS protocol usage.

In the normal operation of COPS-PR, the network administrator will creat the
policies and stock them in the COPS-PR Policy Repository. The COPS-PR PDP
connects to the COPS-PR Policy Repository to retrieve the policy and
configure
its PEP.

I would like to make a SLA server who manages all SLAs of the domain.
Instead of
creating all the policies for the COPS-PR Policy Repository, the
administrator
will creat the policies for the SLA server and stock them in the SLA Policy
Repository. The SLA server connects to the SLA Policy Repository to retrieve
the
policy. The SLA policy helps the SLA server decide to accept or refuse a SLS
requested by his client. Once the SLA server accept a SLS (i.e., the SLA is
established), it will make some changes or generate some new rules in the
Policy
Repository of the COPS-PR Policy Repository so that the COPS-PR PDP can
properly
configure its PEPs.

My questions :
1. Am I permitted to use the COPS protocol for the communication between the
SLA
client and the SLA server ? call the SLA server the PDP and I call the SLA
client
the PEP ?
2. If the answer of question 1 is "yes", is the fact that the SLA PDP make
some
changes in the Policy Repository of COPS-PR PDP conflict with the Policy
Based
Management Framework and Architecture ?

Thank you very much.
