Abstract

A method, system and machine-readable storage medium for providing fault tolerance in a distributed mobile architecture (dMA) system. The method includes receiving a message or failing to receive the message within a predetermined time relating to a first dMA gateway (dMAG) at a second dMAG. It is determined whether the first dMAG is not operational or is otherwise offline based on the received message or the failure to receive the message. One or more dMA nodes associated with the first dMAG are notified in order to request connections to an external system via the second dMAG. The external system is also notified to request connections to one or more dMA nodes associated with the first dMAG via the second dMAG.
