Abstract:

Systems and methods are provided for providing asynchronous communication between a source processor and a destination processor. In one embodiment, a method includes receiving an information request; making a first call to the destination processor, such that the first call includes the information request; and ending the first call while the destination processor determines an information response, such that said ending terminates a synchronous communication between the source processor and the destination processor. Furthermore, the method includes making a second call to the source processor, such that the second call includes the information response; ending the second call, such that said ending terminates a synchronous communication between the destination processor and the source processor; and providing asynchronously the information response.
