Hi Charith,

It depends on how you want to monitor the customer links.

If you need to provide measurements from inside the VRF, then you would need to put the perfSONAR nodes inside the VRF (which means that the customer would be able to send traffic to the perfSONAR host unless you blocked such traffic with packet filters).  Note also that under those circumstances the perfSONAR tests would use bandwidth provisioned for the customer.

Another way to do it would be to provision a separate path for testing that traverses the same path as the customer path.  In that config, you would not use customer bandwidth and the perfSONAR hosts would not be visible to the customer - however, you would be making the assertion that the links provisioned for testing were a sufficiently-good proxy for the customer links that you could say they were equivalent.

Does this help?

Thanks,

Eli

Hi ,

 

I work in an ISP,   I want to know whether perfsonar can be used to monitor BW of links provisioned to customer through service provide MPLS cloud. Customers are

Configured in VRF’s. If this is possible can you explain how.
