Further, the substantial information includes whether or not the information has been transmitted through the backup route, and when the transmission is abandoned, the substantial information itself is information indicating that the transmission has been abandoned. You. The transmission result information included in the substantial information is detected by the transmission result detection unit 14, and when the information is transmitted by the backup route,
Alternatively, when the information is transmission abandonment, the fact is sent to the display control means 15. The display control unit 15 displays the transmission result on the display unit 16. In this case, the identification information of the information is included in the substantial information, and in the case of transmission abandonment, this identification information is transmitted together with the transmission abandonment, so that the transmission abandonment and the information to be abandoned are performed. Display identification information at the same time.

On the other hand, the transmission result detecting means 14 transmits to the transmission destination determining means 12 whether a reception response has been returned from the transmission destination of the transmitted information and whether or not the information has been transmitted through the backup route. Notification is given. The transmission destination determining means 12 is connected to a storage means 17 in which relative station information including identification information of a parent station, a child station, and a brother station concerning the own station is stored. Here, the identification information of the master station, the slave station, and the brother station with respect to the own station is the host name of the computer system used as the transmission destination and transmission source, the IP address when the network 1 is the Internet, the Ethernet address or the host. ID or the like.

More specifically, as shown in FIG. 3, the identification information of the parent station of the own station, the identification information of the brother station immediately above the own station, and the identification information of the brother station immediately below the own station The identification information of the first child station of the own station and the identification information of the last child station of the own station are stored in the storage means 17. When there is no corresponding station, null data (for example, 000) is set corresponding to the station.
An example of correspondence with each station in FIG. 4 is as follows.
In -1, the identification information of the parent station of the own station, the identification information of the brother station immediately above the own station, and the identification information of the brother station immediately below the own station are all (000), and The identification information of the longest child station and the identification information of the last child station of the own station are stored. Second generation station 3-
23, the identification information of the parent station of the own station, the identification information of the brother station immediately above the own station, the identification information of the brother station immediately below the own station, the identification information of the child station of the own station, the identification information of the own station, All of the identification information of the terminal station is stored. In the station 3-22, the identification information of the child station of the own station and the identification information of the terminal station of the own station are both (000), and in the station 3-21, , Identification information of the brother station under one's own station,
The identification information of the longest child station of the own station and the identification information of the last child station of the own station are both (000). In the third generation station 3-33,

0), and the identification information of the first child station of the own station matches the identification information of the last child station of the own station. In the sixth-generation station 3-61, all information other than the identification information of the master station of the own station is (000).

The transmission destination determining means 12 transmits information to the next lower brother station of the same generation based on the identification information in the storage means 17 and the relative information of the transmission source detected by the transmission source detecting means 11. . If there is no lower brother station, the information is transmitted to the parent station. That is, in the example of FIG. 4, the information is transmitted clockwise. When there is a slave station, information is transmitted to the slave station. Further, when the transmission result detecting means 14 notifies that the reception destination of the information transmitted does not return a reception response, and when it is notified whether the information is transmitted by the backup route, the backup route is used. Submit information. That is, in the example of FIG. 4, information is transmitted counterclockwise, which is opposite to the clockwise direction.

When the transmission result detecting unit 14 notifies the transmission result detecting unit 14 that the transmission destination of the information transmitted through the backup route does not return a reception response, the transmission destination determining unit 12 sets the master station as the transmission destination and gives up the transmission. An instruction to be notified is given to the transmitting means 13. In response to the above result, the transmitting unit 13 transmits information or a notification of the transmission abandonment to the corresponding destination (that is, sets a new destination). Here, the information to be transmitted includes, firstly, monitoring information transmitted from the master station to the slave station. This is, for example, the pi in the UNIX command.
The ng command is used. That is, by using the ping command, a required packet is sent to the host of each station,
When waiting for a return, the parent station only needs to transmit to the child station that is the first child, and the other stations need to transmit to the next lower brother station, so that the load can be distributed. The transmitted information includes, secondly, distribution information distributed from a master station to a slave station. For example, a tar command or a dd command in a UNIX command is used. For example, the tar command,
Alternatively, when the upgraded program is distributed to the host of each station using the dd command, the master station may transmit to the child station which is the first child, and the other station may transmit to the lower brother station, The load can be distributed.

The computer system of each station described above is, for example,
It is configured as shown in FIG. That is, the CPU 30 controls each unit using the program and data in the main storage device 31. A keyboard control unit 33, a display control unit 34, a mouse control unit 35, a printer control unit 36, a magnetic disk control unit 37, and a communication interface 38 are connected to the CPU 30 via a bus 32. A keyboard input unit 39 for inputting information is connected to the keyboard control unit 33, and a C for displaying information is connected to the display control unit 34.
The RT display device 40 is connected, and the mouse control unit 35 includes:
A mouse 41, which is a pointing device used for menu selection and the like, is connected.
A printer device 42 for printing information is connected, a magnetic disk control unit 37 is connected to a magnetic disk device 43 for storing data and files, and a communication interface 38 is connected to the network 1 for information. A communication processing unit 44 for performing transmission / reception processing is connected.
Then, the information I arriving from the network 1 is received by the communication processing unit 44, and is divided into, for example, a transmission source and actual information and transmitted to the CPU 30. The destination, information to be further transmitted, or information indicating that transmission has been abandoned is provided from the CPU 30 to the communication processing unit 44 via the communication interface 38, where it is formed into a frame format in the network 1,
Sent to Further, a response requested by a UNIX command ping command or the like is prepared by the CPU 30 and transmitted to the communication processing unit 44. Information such as a program transmitted by the UNIX command tra command or dd command is stored in the main storage device 31 or the magnetic disk storage device 43.

In each computer system having the above-described configuration, for example, the CPU 30 performs the operations of the flowcharts of FIGS. 6 to 11 based on the program stored in the main storage device 31 to execute the processing by the respective units of FIG. Will be
In addition, the main storage device 31 stores the identification information stored in the storage unit 17 of FIG.

The processing will be described below with reference to the flowcharts of FIGS. First, information is received (S11). Then, the transmission source of the received information is detected (S12). That is, the identification information of the transmission source of the information related to the reception is compared with the identification information of each relative station stored in the storage unit 17, and the parent station, the upper brother station, and the lower brother station are compared. ,
It is detected whether the station is sent from the first child station (the first child station), the last child station, or another station (S12). FIG. 6 shows a case from the parent station, FIG. 7 shows a case from the upper brother station, and FIG. 8 shows a case from the lower brother station. FIG. 9 shows a case where the first child (the first child) is from the station, FIG. 10 shows a case where the first child (the first child) is from the last child, and FIG. I have.

If it is from the master station, it detects what the own station is to see from the master station (S13). In other words, if there is no upper brother station, it is the first child station, if there is no lower brother station, it is the last child station, and if there is no upper brother station and one lower brother station, it is one child. Bureau. If the child is the firstborn, the received information is transmitted to the next lower brother station (S14). And whether or not the transmission was performed properly,
For example, detection is performed based on the presence or absence of a response (S15). Here, if the transmission is not performed properly, the information is transmitted to the master station in reverse (S16). In this case, the fact that the rotation is reverse is included in the information. On the other hand, when it is detected in step S13 that the child is the last child, the received information is transmitted to the next higher brother station (S24). Then, whether or not the transmission has been properly performed is detected, for example, by the presence or absence of a response (S
25). Here, if the transmission is not performed properly, that is, since the reverse information transmitted from the parent station to the youngest child cannot be transmitted to the next elder brother station, the information of the transmission abandonment is transmitted to the parent station (S26). ).

When the processing in steps S16 and S26 is performed, or when the flow branches to YES in steps S15 and S25, it is detected whether or not a slave station exists (S17). Here, if there is no slave station, the process ends. If there is a child station, the information received from the parent station is transmitted to the first child (longest child) station (S18), and whether or not the transmission has been properly performed is detected by, for example, the presence or absence of a response. (S19). If the information has been properly transmitted, the fact that the information has been normally transmitted to the next generation is returned to the master station (S23), and the process ends. On the other hand, if it is detected in step S13 that there is only one child, it is detected whether or not there is a child station (S27). Here, if there is no slave station, the sixth generation station 3-6 in FIG.
1 and returns normal to the master station (S2
3). If there is a slave station, step S18
Proceed to and perform the processing.

If the information cannot be properly transmitted to the first slave station, if it exists, the information received from the master station is transmitted to the last slave station (S20), and the transmission is properly performed. It is detected whether or not a response has been made, for example, based on the presence or absence of a response (S21). If the information has been properly transmitted, the fact that the information has been normally transmitted to the next generation is returned to the master station (S23), and the process ends. If the information cannot be properly transmitted to the last child station, the information of the transmission abandonment is transmitted to the parent station (S22), and the process ends.

If it is determined in step S12 that the transmission source is from the next upper brother station, it is determined whether there is a next lower brother station as shown in FIG. 7 (S31). If there is no younger station, the fact that the transmission has been normally made is returned to the parent station (S23), and the process ends. On the other hand, if there is a younger station, the transmission is performed to the younger station (S32), and whether or not the transmission is appropriately performed is detected by, for example, the presence or absence of a response (S3).
3). And if the information is sent properly,
The fact that the data has been transmitted normally is returned to the master station (S35), and the process ends. If the transmission is not properly performed, the information is transmitted to the master station in reverse (S34).

If it is determined in step S12 that the transmission source is from the next lower station, processing is performed as shown in FIG. That is, in this case, the transmission is performed in the reverse direction. Here, it is detected whether or not there is an older brother station (S36). If there is no older brother station, it is returned to the master station that transmission was normally performed in the reverse direction (S40). It ends. On the other hand, if there is a brother station, the transmission is performed in the opposite direction to the brother station (S37), and whether or not the transmission has been properly performed is detected, for example, by the presence or absence of a response (S37).
38). If the information has been properly transmitted, a message indicating that the information has been transmitted normally in a reverse direction is returned to the master station (S40), and the process ends. The information is transmitted to the station in reverse (S39).

If it is determined in step S12 that the transmission source is from the first child (longest child) brother station, processing is performed as shown in FIG. That is, when the information arrives from the first child station, it can be determined that the information has been transmitted backward in the lower generation and arrived from the first child station. Becomes Step S
In step 12, when it is detected that the transmission source is from the terminal station, processing is performed as shown in FIG. In other words, when the information arrives from the terminal station, it can be determined that the information has been transmitted normally in the lower generation and arrived from the terminal station, it is determined to be normal, and the processing is terminated (S42).

If it is determined in step S12 that the transmission source is from another station, processing is performed as shown in FIG. In other words, when information is transmitted from another station, it is certain that the information is not transmitted in a normal direction, so that the information includes a message indicating that the information is transmitted in the reverse direction, or the transmission is abandoned. It is detected whether it has been performed (S43). Here, if it is detected that the transmission has been abandoned, it means that information transmission by normal rotation and reverse rotation could not be performed in the next generation. Therefore, transmission of information to the next generation is abandoned, and the process ends. When detecting the reverse rotation, the information is transmitted to the terminal station, and the information is transmitted by the reverse rotation.

In the above processing, the transmission result is the CRT
It is displayed on the display device 40. In the network system having the hierarchical structure shown in FIG. 4, the transmission results are sequentially aggregated to the master station of a higher generation, and this is displayed on the CRT display device 40. For example, the network administrator can see this. Thus, maintenance of a route where transmission is not properly performed can be performed.
