Methods and systems for automatically tracking the rerouting of logical circuit data in a data network
First Claim
1. A method of rerouting data, the method comprising:
- rerouting data from a logical circuit to a logical failover circuit when the logical circuit fails based on an exceeded quality of service parameter, the logical failover circuit selected based on a committed bit rate, a variable bit rate, or an unspecified bit rate; and
rerouting data from a first set of switches to a second set of switches in the absence of a failure associated with the logical circuit, the logical circuit comprising variable communication paths, and the second set of switches to form a route associated with the variable communication paths that is not predefined and that is dynamically defined at a time of automatic rerouting while maintaining the logical circuit through the second set of switches.

Abstract
An example method involves rerouting data from a logical circuit to a logical failover circuit when the logical circuit fails based on an exceeded quality of service parameter. The logical failover circuit is selected based on a committed bit rate, a variable bit rate, or an unspecified bit rate. The example method also involves rerouting data from a first set of switches to a second set of switches in the absence of a failure associated with the logical circuit. The logical circuit comprises variable communication paths, and the second set of switches are to form a route associated with the variable communication paths that is not predefined and that is dynamically defined at a time of automatic rerouting while maintaining the logical circuit through the second set of switches.
