DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, in one embodiment of the present invention, when a sending job 1, which is a job on the data sending side, sends data, a receiving job 2, which is a job that should receive the transmitted data, exists. destination center determining means 3 for determining whether the side host computer exists in the same center as the sending side host computer where the sending side job 1 exists, or in a different center; All operation management jobs existing in the host computers within the center are registered in advance in the intra-center destination management table 4 for managing data transmission destinations within the center. When the determining means 3 determines that the receiving host computer exists in the same center as the transmitting host computer, the destination of the receiving job 2 is determined using the intra-center destination management table 4, and the data is sent to that destination. an intra-center transmission means 5 for transmitting data, and a main host computer, which is a host computer having a communication route with other centers among the host computers of each center, and a center management system for managing the destination of data transmission between centers. It is registered in the table 6 in advance, and when the destination center determining means 3 determines that the receiving host computer is located in a different center from the transmitting host computer when transmitting data, the center management table 6 is used to register the data. The main host computer of the center where the receiving job 2 exists is determined as the destination, and then the main host computer of the center where the receiving job 2 exists via the main host computer of the center where the sending job 1 exists. and an inter-center transmitting means 7 that transmits data to the host computer, and the inter-center transmitting means 7 receives data transmitted from a center different from the center where the own host computer is located, and transmits data to the intra-center transmitting means 5 from the receiving side job 2. and inter-center receiving means 8 for determining the destination of the data and requesting data to be transmitted to the destination.

One of the features of the embodiment of the present invention is that in response to a data transmission request by the sending job 1, the destination center determining means 3 determines whether the sending host computer and the receiving host computer are in the same center. If they exist in the same center, the intra-center transmission means 5 transmits them to the receiving host computer using the intra-center destination management table 4, If the job exists in a different center, first, the inter-center transmission means 7 of the sending host computer uses the inter-center management table 6 to send it to the main host computer of the center where the sending job 1 exists, and The inter-center transmitting means 7 of the host computer sends it to the main host computer of the center where the receiving job 2 exists, and the inter-center receiving means 8 of the main host computer of the center where the receiving job 2 exists receives it. The in-center transmission means 5 transmits the data to the receiving job 2.

Next, regarding the operation of one embodiment of the present invention,
This will be explained in detail with reference to the drawings. In FIG. 2, in response to a data transmission request from sending job 1, destination center determining means 3 determines that sending job 1 and receiving job 2 exist in a host computer within the same center. The host-to-host communication management operations at the sending host computer at the time are shown.

Referring to FIG. 2, the destination center determining means 3 first determines that the sending job and the receiving job exist in a host computer within the same center, and that the transmission is within the center. (Step 21).

In response to this determination, the intra-center transmission means 5 determines the destination of the receiving job 2 from the intra-center destination management table 4 (step 22), and further transmits data to the receiving job 2 (step 23). .

In FIGS. 3 and 4, in response to a data transmission request from a sending job 1, a destination center determining means 3 exists in a host computer of a center where the sending job 1 and the receiving job 2 are different. Then, the inter-host communication operation when the determination is made is shown.

FIG. 3 particularly shows the inter-host communication operation at the center where the sending job 1 exists, and FIG.
The inter-host communication operation at the center where the receiving job exists, which received the transmission data according to the operation shown in , is shown.

Referring to FIG. 3, first, sending job 1
When the destination center determining means 3 determines that the transmitting side host computer and the receiving side host computer exist in different centers (step 31), the inter-center transmitting means 7 transmits the data from the center management table 6. The main host computer of the center where the receiving job 2 exists is determined from the data (step 32), and the data is further transmitted to the main host computer of the center where the sending job 2 exists (step 33). Then, the inter-center transmission means 7 of the main host computer that has received the transmitted data transmits the data again to the main host computer of the center where the received job 2 is located (step 3).
4).

Referring to FIG. 4, in the main host computer of the center where the receiving job 2 exists, inter-center receiving means 8 receives data transmitted from another center by the operation shown in FIG. Step 41), the intra-center transmission means 5 determines the destination of the receiving job 2 from the intra-center destination management table 4 (step 42), and further transmits the data to the host where the receiving job 2 exists (step 43). ).

In this way, the host computer where the sending job 1 exists and the host computer where the receiving job 2 exists can communicate without having a direct communication path.

[0016]

Effects of the Invention The present invention classifies a set of connected hosts as a center for each business unit, and when a sending host computer and a receiving host computer exist in the same center, data It has a data transmission method and a data transmission method between centers when they are located in different centers, and has the effect that the sending host computer and the receiving host computer can communicate even if they do not have a direct communication path. .
