As shown in the figure, the BP 20 includes a MHOSTADP (Multi-Host Adapter) 21 for performing an external host 10 connection and communication function; A gateway server (GWSVR) 22 for relaying the TCP / IP protocol; A Middle Speed Terminal TTCP Manager (MTST) 23, which is a TTCP protocol control and middle speed terminal manager; A Multi RLA Server Agent (MRSAGT) 24 that is responsible for circuit management and interface with the external RLA server 30; And LANADP (Lan Terminal Adapter) 25, which is an integrated terminal manager, each process is started one by one to process a requested task.

Meanwhile, the RLA server 30 of FIG. 1 serves as a remote data link controller as a middle speed terminal controller. In general, the host 10 is a server and the RLA server 30 is a client. .

In the conventional BP 20 configured as described above, as shown in FIG. 2, the intermediate speed terminal and the automation device use a fixed path of MRSAGT 24 → MSTTM 23 → GWSVR 22 → MHOSTADP 21. The host 10 is transacted with the host 10, and in the case of an integrated terminal, the host 10 is transacted with a fixed path of LANADP 25 → GWSVR 22 → MHOSTADP 21.

Meanwhile, internal processes of the BP 20 communicate with each other using a message queue method using IPC as shown in FIG. 3, and communication with the outside uses a socket in a TCP / IP network. .

However, in the past, the BP was developed to be small, so that the number of accessible terminals and the amount of simultaneous transactions were small, making it difficult to distribute data. That is, in the conventional BP (XBP), since one process processes one data at a time, the processing speed is slow, and the maximum number of terminals that can be connected to one BP is small. There is a problem that the installation cost and maintenance cost increases because there is a large number, and since the data is not distributed, the more the number of access terminals and transactions, the lower the processing speed and performance, and only one process because it communicates through a fixed path. In case of failure, there was a cumbersome and inefficient problem of restarting the entire BP.

Therefore, the present invention was created in order to solve the above problems, a branch process that allows more terminals to be connected to one BP, and can be handled with a large number of connected terminals at the same time, stable processing And its purpose is to provide a data distribution processing method thereof.
