What are some examples of networks that are already running MPLS?
It used to be easy to maintain a list of worldwide MPLS deployments, these days it would be easier to maintain a list of networks that haven’t deployed MPLS in one fashion or another. Nearly every global service provider now offers MPLS-based VPN services and many are using MPLS internally for traffic engineering. Maintaining an accurate list of actual service deployments would be nearly impossible.
