Description

Description Network system matching 5ϋϋ method and device

The present invention relates to a network system matching method and apparatus, and more particularly, to a network system matching iill! Method and apparatus for performing network system matching '14 in a network system to which a plurality of networks are connected.

Background art

FIG. 1 shows a system configuration diagram of an example of a network system in which a plurality of networks are connected. In the figure, a network 10 is composed of a transmission device 11 and a device 12 connected to each other, and a device DTE 1 is connected to the device 11. The network 20 is composed of a device 21 and a transmission device 22 connected to each other, and the terminal DTE 2 is connected to the device 22. Further, the transmission devices 11 and 21 are connected by a path 40. Configuration management devices 15 and 25 are provided in the networks 10 and 20, respectively. When constructing such a system, the system designer prepares a system design document 50. Based on the system design document 50, the configuration information creator manually inputs the configuration information of each network 10 and 20 from each of the configuration management devices 15 and 25 to create the configuration information 16 and 26. .

For example, when realizing data communication between terminals DTE1 and DTE2, the configuration management device 15 inputs the data passing position on the road connected to the corresponding port of the transmission device 12 from DTE1 of the network 10 using the configuration management device 15. In the network 20, the data passing position on the road connected from the DTE 2 to the corresponding port of the feit device 21 is input. The configuration information of networks 10 and 20 shown in FIGS. 2 (A) and 2 (B) created in this way has a consistency of ίϋ! Within the respective ranges of network 10 and network 20. Is done. In the past, the connection between terminals across networks was determined by the configuration information creator. For this reason, there was a problem that connection inconsistency between terminals occurred due to an error made by the creator of the configuration information. The following are the causes of such terminal mismatch.

First, there is an inconsistency due to the end-of-service 1 鹡 Ri Sakuto. When creating configuration information, when inputting various terminal information such as the transmission data type, format, bandwidth used, and mounting position in the device from the configuration management devices 15 and 25, the information is input using the network 10 and the network 20. If there is an error in the information, the opposite terminal will be inconsistent and the data will not be communicated.

Second, there is inconsistency due to the creation of network connection information. As shown in Fig. 1, the networks are connected by the ^ path, but on the path, the bandwidth is divided in units of TS (time slot), and the TS manages the bandwidth. The TS is assigned a number corresponding to the number of band divisions according to the road capacity, and this number indicates a position in the road.

In FIG. 1, when terminals DTE 1 and DTE 2 are connected, in network 10, along with the various terminal information described above regarding the storage terminal DTE 1, i¾t path 40 connected to network 20 in configuration information creation,路 The ports of the device 12 and the TS occupied by the DTE 1 on the transmission line are input from the configuration management device 15.

Also, in the network 20, a path 40 connected to the network 10 in the configuration information creation, a port of the transmission device 21 connected to the path 40, and an on-road Of each TS occupied by the DTE 2 is input from the configuration management device 25. However, if there is an error in the input information, the network connection will be inconsistent, and data will not be communicated between the terminals DTE 1 and DTE 2.

In the past, although connection was established within each network, the connection between terminals across networks was determined by the configuration information creator, and connection failure between terminals due to an error by the configuration information creator. When matching occurred, there was a problem that it was not possible to confirm the connection mismatch between terminals. Disclosure of the invention

As "" ^ of the configuration information of the network accommodating the terminal, the terminal connection information of the mi terminal and the terminal accommodated in the other network connected to the mi terminal is input to the self-matching l! Information. ,

It is configured so that the opposing legitimacy of the terminals is determined by extracting the opposing terminal connection information of the opposing terminals from the editing information and comparing them.

According to such a network system matching method, when the configuration information creator erroneously uses the opposite terminal connection information of one of the terminals to cause a connection mismatch between the terminals, the configuration information creator transmits the opposite terminal connection information of each of the opposite terminals. By comparing, the connection mismatch between the terminals can be corrected.

FIG. 9 shows a flowchart of an embodiment of the network connection processing executed by the matching confirmation device 60. This process is performed after the connection information creation process in FIG. 7 and the 5-way negotiation process in FIG. 8 are performed.

In FIG. 9, the matching ninja device 60 is the network 1 in which the terminal DTE 1 is accommodated. Focusing on 0, in step S 4 3, path 1 of terminal DTE 1 is recognized from the end 5 ^ of the form information in FIG. 4 (A) in matching magnetism information 6 2 corresponding to network 10, Figure

In the next step S 4 4, a diagram corresponding to the network 20 in the matching magnetism information 6 2

5 From the feii path information in (Β), 認識する Recognize that the device 21 facing the terminal DTE 1 is the path 2 accommodated in the port 1 (passing position). From the connection information in FIG. 5 (C), it is determined that the connection destination of the transmission path 40 of the transmission device 21 is the port 1 (passing position) of the transmission device 12.

In step S45, the connection of network 10 and network 20 is mutually confirmed from the results of steps S43 and S44 described above, and the connection on i ^ path 40 is established. Mutually confirm the passing position of the path between the terminals DTE 1 and DTE 2 ((1) the ports of the devices 12 and 21).

In this way, as the network configuration information "^", the network connection information with the other network connected to the own network is input to the matching 鹳 information, and the networks facing each other are entered. The network legitimacy of the network can be confirmed by extracting the opposing network connection information from the matching magnetism information and comparing.

In steps S11 and S12, a "path number" may be used instead of "fei device number + mounting position" as connection information, and steps S13 to S16 "Route number" may be used instead of "Device number + Port number" as connection information. Further, instead of inputting the connection information from the configuration management devices 15, 25, and 35 to the configuration information, the configuration may be such that the connection information is directly input to the matching information by the matching checking device 60. It is not limited to the example.

Next, as shown in FIG. 10, consider a network system in which networks 10, 20, 30, and 70 are connected. Also in this case, the configuration management device of each network 10, 20, 30, 70 collects the configuration information, and the matching boat ninja device 60 collects the matching iSI shinobi information from these configuration information. And

From the configuration information corresponding to the network 10 in the network, the transmission path accommodating the path of the terminal DTE 1 is recognized, and further, the connection of this feit path is recognized as the feit device 21 of the network 20.

Next, it recognizes from the configuration information corresponding to the network 20 in the matching confirmation information that the network 30 is to be connected next.

Next, it is necessary to recognize from the configuration information corresponding to the network 30 in the consistency view information that the next connection is the network 40, but the network 30 in the collected consistency view information must be recognized. There is an error in the configuration information corresponding to, and the connection of the network 30 (port 2 of the device 3 1) is specified to the port 4 of the transmission device 21, as shown in ① in the figure, and the connection is made next Is mistaken for network 20. In addition, the collected magnetism! If the connection destination of the port 3 of the transmission device 21 is specified to the port 1 of the transmission device 3 as shown by ② in the figure in the configuration information corresponding to the network 20 in the information, step S 4 3 Then, it is assumed that the network 30 is connected next. If the connection between port 1 and port 2 of device 3 1 is recognized by path 1, and the connection of port 3 and port 4 of transmission device 2 is recognized by path 2, network 2 This loops infinitely between the next network connection 0 of network 0 and the next network connection 5 of network 30.

An embodiment for preventing this infinite loop will be described.

FIG. 11 shows a flowchart of another embodiment of the network connection processing executed by the matching device 60.

In FIG. 11, first, as preprocessing, connection information creation processing similar to that of FIG. 7 is executed in step S51, and opposite terminal matching confirmation processing similar to that of FIG. 8 is executed in step S52. In step 3, the network counter N is reset to zero. Next, in step S54, the number N through the network is incremented by one, and then in step S55, one terminal (for example, DTE1) is accommodated from the matching of the opposite terminal. The path accommodating the path of the above terminal is recognized from the configuration information corresponding to the network, and the transmission equipment of the network connected to the Bfc of this path recognizes the terminal.

Next, in step S56, it is determined whether or not the connection of the ^! Path is a network device, and if the connection of the feii path is a network device, the process proceeds to step S57. If the connection destination of the transmission path is a terminal, the matching of the opposite terminal has been confirmed, so network connection is performed in step S58, and this processing ends.

In step S57, it is determined whether or not the network traffic counter N exceeds the network traffic itb limit value TH. Here, if N≤TH, the process proceeds to step S54, and by repeating steps S54 to S57, the feit route accommodating the path of the terminal in the next passing network is recognized. Recognize the transmission device or terminal of the network to which is connected.

On the other hand, if N> TH in step S57, the process proceeds to step S59 and matches. And the process ends.

In this way, the configuration information that defines the operation of the devices that make up each network is collected from each network as matched boat shinobi information, and as the configuration information ~ ¾ of the network that houses the terminal, Matching information of the terminal connected to the terminal accommodated in the other network to be connected is input to the matching 511 fffg, and "^" of the network configuration information is set to "^" of the network connected to the other network connected to the own network. Input the opposing network connection information into the matching magnetism and information, match the opposing terminal connection information for each of the opposing terminals, extract the information from the information, and, based on the opponent terminal connection information, edit the SS The configuration information of the network to which one of the terminals is connected is matched, extracted from the information, and the path of one terminal is connected from the configuration information of the network. Recognizes the next network, extracts the configuration information of the next network from the matching magnetic information, and faces the next network or the other network to which the terminal of one terminal is connected from the configuration information of the ile network. By recognizing the other terminal among the terminals that connect to each other, and by recognizing the other terminal among the terminals facing each other, the connection of the network connecting "^" that connects the terminals opposite to each other is justified. You can endure all sex.

Also, set the upper limit of the number of transit networks in the network connection processing, calculate the number of transit networks when transiting the network, ΐ δπ, compare with the upper limit of transit networks, and set the upper limit of transit network count> transit network count In this case, by terminating the processing as a matching 5 ネットワーク error, it is possible to prevent an infinite loop when confirming the network connection IE correctness.
