A method of distributing software to handle previously unknown event types in a large multi-domain "federation" network of decoupled, event-driven components. The components comprise producer components (10) which produce events and consumer components (25) which consume events to fulfill their specific roles in the federation. A producer component first determines a plurality of new events occurring in the network as a result of a new event type, and classifies the plurality of new events into at least one event-specific class. The producer component then pushes a single event (14) of an event-specific class into the network along with a new software strategy (13) for handling the event-specific class. The new strategy is distributed to the components in the network utilizing push technology (15). If the new strategy is applicable to a given component (31), the new strategy is cached (32) by the component and utilized to process events of the new type. If not applicable to the component, the new strategy is cached (34) by the component for use by downstream components. The process of distributing a strategy is then repeated for each event-specific class. The strategies are cached in the network components and are pushed to new components that bind to the network and subscribe to events of the new type. Thereafter, the new strategies are utilized by the components that received them to process events of the new type. |
