Abstract:
Interconnected data processing nodes can from time to time experience temporary failures or losses of communication links between system nodes. In systems which have a mechanism for determining whether the data processing nodes are operative or not, by providing an epoch number for use as an instance identifier and by providing a mechanism for controlling the generation and propagation of the epoch number, such systems are able to resume their respective tasks when failed nodes or communication links are restored.
