Claim 11:
12. A method of enforcing safety rules on a virtualized wide area network (vWAN), comprising:
receiving, for a virtual connection between a first a first virtual entity in the vWAN and a second virtual entity in the vWAN, a change to a policy for the virtual connection or a change to a configuration of the virtual connection from an operator of a network connected to the vWAN, Wherein the vWAN includes a plurality of virtual network entities associated with geographic locations and virtual connections between the virtual network entities, each virtual connection associated with a respective policy to provide a desired level of service for traffic between a pair of virtual network entities;
detecting a network state of a physical WAN underlying the vWAN;
evaluating a set of safety rules for the operator based on the network state of the physical WAN and the change to the policy or the change to the configuration of the virtual connection to determine whether conditions of the safety rules can be satisfied given the policy, the configuration, and the network state; and
generating an error message in response to at least one of the set of safety rules failing the evaluation.
