Methods and systems to reroute data in a data network
An example method involves, when a first quality of service parameter for a failed logical circuit is equal to or less than a second quality of service parameter for a logical failover circuit, rerouting data from the failed logical circuit to the logical failover circuit without requiring authorization from a customer to communicate the data at the second quality of service parameter. When the second quality of service parameter for the logical failover circuit is a lower level of quality than the first quality of service parameter for the failed logical circuit: a customer is prompted for an authorization to communicate the data via the logical failover circuit at the second quality of service parameter; when the authorization is received, the data is rerouted from the failed logical circuit to the logical failover circuit; and when the authorization is denied, the data is not rerouted to the logical failover circuit.

when the second quality of service parameter for the logical failover circuit is a lower level of quality than the first quality of service parameter for the failed logical circuit:
prompting the customer for an authorization to communicate the data via the logical failover circuit at the second quality of service parameter;
when the authorization is received, rerouting the data from the failed logical circuit to the logical failover circuit; and
when the authorization is denied, not rerouting the data to the logical failover circuit.
