Method and system for dynamic software reconfiguration triggered by component- or system- initiated events

A system for handling events in compositional applications represented as processing graphs, comprising:

• a memory device for storing a program;
• a processor in communication with the memory device, the processor operative with the program to:
• receive an event notification;
• modify a planning domain according to the event notification;
• generate a new processing graph for a previously deployed processing graph by using the modified planning domain;
• determine if the new processing graph is different than the previously deployed processing graph;
• and
• if the processing graphs are different:
• reconfigure the previously deployed processing graph to match the new processing graph;
• or
• deploy the new processing graph and replace the previously deployed processing graph with the newly deployed processing graph.

A computer readable storage medium storing instructions that, when executed by a computer, cause the computer to perform a method for handling events in compositional applications represented as processing graphs, the method comprising:

• receiving an event notification;
• modifying a planning domain according to the event notification;
• generating a new processing graph for a previously deployed processing graph by using the modified planning domain;
• determining if the new processing graph is different than the previously deployed processing graph;
• and
• if the processing graphs are different:
• reconfiguring the previously deployed processing graph to match the new processing graph;
• or
• deploying the new processing graph and replacing the previously deployed processing graph with the newly deployed processing graph.
