Abstract

An apparatus connects to a legacy host computer system of the type having a non-hierarchical file structure for controlling simultaneous communication between it and local processing devices. Provided that the server is awaiting requests, a data retrieval request from a local processor is detected 3 on a preset communications port, and a check is made 4 to determine whether a pool session is available from a queue QA. If a session is available the request is assigned 6 to that session. The server reads 7 the data stream associated with the request, and parses 8 the stream. Connection details are extracted 9 from the requests, and it is determined 10 if the request forms part of an existing conversation. The apparatus improves the efficiency and transparency of communications between computer systems to release legacy based host information for Internet and Intranet technologies. The method and apparatus described use remain connected headers, size adjustable multiplexed memory blocks and pool sessions to optimise use of system resources and make the information available.
