1. A method of rerouting data in a data network, the method comprising:
- updating reroute information in response to a dropped packet associated with a quality of service parameter having been exceeded;
rerouting data from at least one logical circuit to at least one logical failover circuit in the data network when the at least one logical circuit fails based on the exceeded quality of service parameter, the at least one logical failover circuit being selected based on a committed bit rate, a variable bit rate, or an unspecified bit rate; and
rerouted 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 at least one 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
A method and system are provided for tracking the rerouting of logical circuit data in a data network. A disclosed example method involves updating reroute information in response to a dropped packet associated with a quality of service parameter having been exceeded. Transmitted data is rerouted to at least one logical failover circuit in the data network from at least one failed logical circuit associated with the exceeded quality of service parameter. The at least one logical failover circuit is selected based on a bit rate capability specified to be one of a committed bit rate, a variable bit rate, or an unspecified bit rate.
