Abstract
Example embodiments are directed to methods of ensuring high availability of a network using asynchronous checkpointing of application state data related to an object. Example embodiments include a method of asynchronous checkpointing application state data related to at least one object, including receiving application events and processing the application events to obtain new application state data. The method further includes modifying at least a portion of previously stored application state data and asynchronously and independently checkpointing the modified application state data based on whether the modified application state data has reached a stable state. Example embodiments also include a method of ensuring consistent application state data across a network. This method may include having at least two CAPs independently and asynchronously storing application state data related to at least one object at two different network nodes and automatically auditing the stored application state data to ensure data consistency.
