METHOD, PROGRAM, AND SYSTEM FOR COMMUNICATING BETWEEN FIRST HOST SYSTEM AND SECOND HOST SYSTEM IN DATA PROCESSING SYSTEM (SYSTEM AND METHOD FOR COMMUNICATION BETWEEN HOST SYSTEMS USING TRANSACTION PROTOCOL AND SHARED MEMORY)

摘要

PROBLEM TO BE SOLVED: To provide a system and method for communication between host systems using a transaction protocol and shared memory. SOLUTION: The shared memory is initialized based on a finding process in communication fabric so that at least one end point has an address range in the shared memory of at least two host systems. For communication between the end point and a root complex of the same or different host systems using the shared memory of the host systems, transaction oriented protocol can be established. The transaction oriented protocol specifies a series of transactions to be executed by various elements such as the root complex or the end point in order to push or pull data. Various combinations of push transactions and pull transactions can be used. COPYRIGHT: (C)2008,JPO&INPIT
