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 .
