In one embodiment, the event bus includes an interface for receiving an event message; a routing manager configured to determining whether an event message received at the interface should be routed to a destination device or whether it should be queued for retrieval by the destination device; a queue for storing the event message; and a network event storage device configured to store a copy of the event message.
