METHOD, PROGRAM AND SYSTEM FOR PERFORMING COMMUNICATION BETWEEN FIRST AND SECOND HOST SYSTEMS IN DATA PROCESSING SYSTEM (SYSTEM AND METHOD FOR COMMUNICATION BETWEEN HOST SYSTEMS USING SOCKET CONNECTION AND SHARED MEMORY)

摘要

PROBLEM TO BE SOLVED: To provide a system and method for communication between host systems using socket connection and shared memories.

SOLUTION: In the socket-based communication, a work queue in host systems can be used to listen for an incoming socket initialization request. As shown in Fig. 10, a first host system 1010 wishing to establish socket communication connection with a second host system 1020 can generate a socket initialization request work queue element in its work queue and can inform the second host system 1020 that the socket initialization request work queue element is available for processing. Then, the second host system can accept or deny the request. When the second host system accepts the request, the second host system returns a second half of a socket parameter for use by the first host system in performing socket based communications between the first and second host systems.
