Patent ID: 7539734

Claim:
A system of communicating between service nodes in a service grid comprising: means for transmitting a requesting service node message from a requesting service node in a service grid directed to a destination service node in the service grid, the requesting service node message having a requesting service node message format associated with a version of the requesting service node; means for receiving the requesting service node message at an inter-operability service in the requesting service node message format; and means for determining a destination service node message format for the requesting service node message based on a version of the destination service node, wherein the means for determining further comprises: means for requesting the version of the destination service node from the destination service node; means for receiving the version of the destination service node at the inter-operability service; means for determining whether the version of the destination service node is known at the inter-operability service; means for converting the requesting service node message from the requesting service node message format to the destination service node message format at the inter-operability service responsive to determining that the version of the destination service node is known at the inter-operability service; means for updating the version of the destination service node to a most current version at the inter-operability service responsive to determining that the version of the destination service node is unknown at the inter-operability service; means for converting the requesting service node message from the requesting service node message format to the most current version at the inter-operability service to provide the requesting service node message in the destination service node message format; and means for transmitting the requesting service node message from the inter-operability service to the destination service node in the destination service node message format.
