For private, point to point, line, I agree with a previous posting on the subject: "As for the rest, CIR, Latency, Jitter, Loss ..... this can be tested prior to customer handover with any number of tools and protocols including IEEE 802.11ag/ah, ITU-T 1731, IETF RFC2544. " -Rich Andreas Asking to receive the testing report as part of an acceptance process is not unusual. For corporate IP service, you may want to measure end to end performance and not get too specific in the core. Writing an SLA against city pair performance is a responsible method to do this e.g. "Islamabad->Kabol not equal to more than 1ms". That should encompass everything along the required path(s) and hopefully incent your provider to keep their network up to snuff and their MTTR low. You may also consider codifying the MTTR i.e. MTTR = < 2 Hours "or" service credit. (Again, depends on your economic power). Don't forget that your power to negotiate SLA's with service credits is proportionate to the size of the purchase. Buying 10 Mb/s vs. 10 Gb/s services are two different types of economics when it comes to SLA.
