Abstract:
An example method of rerouting data involves rerouting a logical circuit from a first set of switches to a second set of switches to communicate data between network devices without breaking the logical circuit. The logical circuit comprises variable communication paths. The second set of switches is 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. The example method also involves rerouting the data from the logical circuit to a logical failover circuit in the data network when the logical circuit fails based on a committed information rate having been exceeded. The logical failover circuit comprises an alternative communication path to communicate the data.
