Publisher/subscriber architecture for multi-device activities
View Patent ↗A publisher-subscriber architecture with standardized and/or dynamic event/message look up can be implemented on wagering game establishment networks to establish a robust and flexible reporting and reacting mechanism. Processes that operate in accordance with the publisher-subscriber architecture can coordinate operations across multiple devices in a wagering game establishment, and even across multiple wagering game establishments, in response to an event occurring. Processes can operate as publishers and/or subscribers, and can reside on a WGM (e.g., standalone, portable, etc.) or a server. Processes operating as publishers on a WGM can publish information about events that occur on the WGM. Processes operating as subscribers can interpret published event information from different vendors and use published event information in a number of different ways.
