Title: RE: access request initialed by other sources than PEPs in COPS-P R

Thanks to Sanjeev and Muhammad for the information.

 

Does anybody know any commercial COPS server stack (in addition to Trillium, Redvision and Vovida)?

And also is there any implementation of COPS-MPLS? Any information will be appreciated.

Hi Jianli,

 

I doubt if there is a free COPS server source code available. So far I've found COPS client source code from Intel and IPHighway and they both treat the server as a black box and provide the binaries for testing. The reason I believe is that the source code(server) has to deal with policies in the PIB which will also contain information of the policies in the Policy Repository and becomes almost a full blown system. You may look at IPHighway(www.iphighway.com) COPS implementation as they have mentioned about Policy MIBs and extend it for your own implementation of the server code.

 

Good luck,

 

Sanjeev Chakravarty

Does anybody know where I can download free COPS server source code? Thanks.

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.

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
