  • Field The field of the invention relates to networking and in particular to communications for a gaming network.
  • Gaming has experienced tremendous growth in recent years and the growth trend continues to accelerate showing no signs of abating. As a result, gaming establishments and vendors have continued to automate their equipment and services in efforts to provide improved gaming experiences in a cost effective manner.
  • gaming devices e.g., slot machines, video poker, etc.
  • processors and software are now generally equipped with processors and software, so that the device may collect, monitor, control, and report games and their associated metrics.
  • This information allows for effective planning, maintenance, configuration, and upgrades. In some instances, this information is manually collected by physically visiting a particular gaming device and interfacing with its locally resident software. In other instances, this information is collected remotely over a network via interfaces to a central or remote processing site. In instances, where gaming devices interface with a remote processing site over a network, the interface is typically implemented with complex and sometimes proprietary protocols. This means that the gaming software has to know how to interface with the protocols and thus has to be aware of the syntax and semantics associated with those protocols. If protocols are changed or upgraded, then newer versions of the gaming software have to be upgraded on each gaming device which is interfaced to the remote processing site. Additionally, the remote processing site has to understand the protocols and has to understand what data is being received from each transaction and how to handle that data.
  • gaming networks that interface gaming devices to remote processing sites are tightly coupled, difficult to maintain, difficult to upgrade, and highly dependent on specific protocols. Consequently, enhancing or upgrading gaming devices remains a resource-intensive and, in some cases, a cost prohibitive exercise.

For example, if a betting game being executed on the gaming device is driven from data values stored in the local database, then when a local database command that updates those data values within the local database is processed, the betting game will alter its appearance and/or execution states based on these revised data values.
