Management of Application to Application Communication Requests Between Data Processing Systems

摘要

A mechanism is provided for managing an application communication request. A first operating system passes a call from a first application in a first data processing system intended for a second application in a second data processing system to a first host fabric interface controller in the first data processing system without processing the call. The first host fabric interface processes the call using state information associated with the call to determine the second data processing system with which the call is associated. The first host fabric interface initiates a connection to a second host fabric interface in the second data processing system and transfers the call to a second operating system in the second data processing system via the connection to the second host fabric interface. The second data processing system then processes the call intended for the second application without assistance from the second application.
