Estimating the term…
In a network service provider environment, the service provider infrastructure is protected by separating internet routing from the default context and placing it within a virtual private network context. Packets received from the public internet are encapsulated for transit through the service provider infrastructure based on the packet source being the public internet. MPLS VPN technology may be used in the encapsulation technique. The architecture removes the public part of the underlay network and tunnels it through a new overlay. The result is that internet traffic is contained in a separate routing domain, hiding the network infrastructure from that untrusted service traffic that transits the network.
