A method and system are provided for providing a failover circuit for
rerouting logical circuit data in a data network. An alternate
communication path is identified for routing data for a logical circuit
in the data network. An inactive logical circuit is then selected in the
data network for communicating the data over the alternate communication
path. The inactive logical circuit is then designated as a failover
circuit for rerouting the data for the logical circuit in the data
network. The inactive logical circuit may be selected by selecting a
currently unused logical connection in the data network for communicating
the data. The inactive logical circuit may also be selected by
provisioning an inactive logical circuit in the data network. The
inactive logical circuit may be provisioned by sending configuration data
describing a logical data path over the alternate communication path to a
network device in the data network.
