HIERARCHICAL FAILURE RECOVERY FOR A NETWORK-BASED SERVICE USING STATECHART OBJECTS

Abstract:

Various aspects of a requested transport or delivery service can be modelled and computationally represented using different classes of statechart objects. Some of the statechart objects can be transitioned between one or more composite states each having a plurality of substates. In this manner, delays, errors, and failures relating to the transport or delivery service can be tracked using state transitions of the statechart objects. And dynamic recovery functions to such delays, errors, and failures can be performed in response.
