One very interesting part of being an independent MPLS consultant is having the opportunity to view the ping time of identical networks at the time of migration from one carrier to another. It is the only time to obtain empirical measures of latency between different locations on a network. This data is invaluable to our work.
When you investigate different carriers, they will be able to provide you with their service level agreements for different paths on a network, but this number is invariably a worst case scenario. If a carrier has Looking Glass, they can provide latency numbers for a limited number of POP to POP paths, but not your distinct network. That is why SD-WAN-Experts records this information for the benefit of our clients.
