Method and system for providing a failover circuit for rerouting logical circuit data in a data network
First Claim
1. A method for providing a failover circuit for rerouting logical circuit data in a data network, the method comprising:
- identifying an alternate communication path for routing data for a logical circuit in the data network;
selecting an inactive logical circuit in the data network for communicating the data over the alternate communication path; and
designating the inactive logical circuit as a failover circuit for rerouting the data for the logical circuit in the data network.

Abstract
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.
