COMMUNICATION BETWEEN PARTITIONS IN A LOGICALLY PARTITIONED SYSTEM BY BYPASSING THE NETWORK STACK WHEN COMMUNICATING BETWEEN APPLICATIONS EXECUTED ON THE SAME DATA PROCESSING SYSTEM

摘要

A mechanism is provided for communicating between a plurality of applications. An application programming interface (API) associated with an originating application running on a first logical partition in a plurality of logical partitions of a logically partitioned data processing system receives a request to send data to a destination application. The API sends a request to identify a location of the destination application to a virtualization management mechanism. Responsive to receiving a response from the virtualization management mechanism, the API determines whether the location of the destination application is a second logical partition in the plurality of logical partitions of the logically partitioned data processing system. Responsive to the location being the second logical partition, the API uses a bypass protocol to send the request from the originating application to the destination application.
