This alternative embodiment adopts the following technical solutions:

A fast fault information collection tool consisting of a client (equivalent to the above client device), a business logic control manager (manager) and a communication agent module (Agent) (the communication agent module is related to the proxy server described below) The three components are composed of three components, wherein the client mainly provides interface display and human-computer interaction. The business logic control processing module mainly implements parallel processing between each network element and serial processing of each data item of a single network element, and the communication agent module implements Direct communication of network elements, without any business logic processing.

The following are the relationships between the various modules and modules of this alternative embodiment:

1, the client

The client implements functions such as operation interface display, configuration file reading, report output, file downloading, and memory management. The components included include:

1) System setting, the collection tool accesses the communication device through the agent agent, and needs to log in to the agent agent before performing the collection, and set the protocol (Internet Protocol, IP for short) to be interconnected between the networks of the login agent in the system setting menu. And the port, the connection test between the collection tool and the agent can be performed, and the directory for outputting the report can also be set in the system setting.

2) Importing NEs, you can import the NE information report exported by the E300/U3 network management system into the list of selected NEs, including NE device types, subracks, and slots. Currently, the txt format is supported. Adding information in the list of selected NEs can be added to the list of selected NEs to collect the selected NEs.

3) Filtering NEs, filtering the list of selected NEs by NE name, NE ID, device type, and IP address, and supporting fuzzy query.

4) Add a new NE and add a record to the selected NE list in the selected NE list. You must enter the NE name, device type, NE ID, and IP address when adding an NE. Otherwise, Allow saving.

5) Delete the NE and delete the selected record in the selected NE list to support multiple selection.

6) Save and save the current content in the selected NE list.

7) Start collecting, query data from the device according to the commands defined in the data collection configuration file, collect the network elements in the selected network element list, and save the collected results to the data file.

8) Stop the acquisition and stop the acquisition and execution.

9) Clear the data, clear the selected network element and the selected network element data.

The collecting device adopts a configuration file to organize a fault command to be collected, and the process of initializing the data is to read the configuration file. Store data structures. The device type, the board type, the collection type, and the collection command are used to store the mappings between the board types of the specific NE types and the commands to be queried.

The process of performing the acquisition is to call the entry function of the manager module, and then start the Manager module processing flow.

The Manager module implements communication functions, including reading memory, organizing data, constructing messages, issuing and accepting commands, and reporting returns. The Manager module processing process consists of the following steps:

1), using the thread pool mechanism to achieve multi-network element concurrency mechanism.

2) Obtain the information of the network element building chain, and the agent module and the network element establish a chain, and the client does not directly connect to the network element.

5) Process each command of the board of the network element, and assemble the command into a message and send it to the agent.

6), issue a command, register the timeout node, block this command processing thread to wait. The command returns or times out, the unlocking continues processing, and the packet is parsed and reported to the client module.

7) Generate a report file of the collected result data and save it to the local.

2, the proxy server

The proxy server is a tool that connects the client and the device, and establishes a chain with the network element to complete the delivery of the command. The agent allocates and sends commands to the NE according to different command types, and the receiving device responds or reports the command to the client.

The proxy server is divided into four functional modules:

1. Communication management module between collection tools:

A connection is established with the client module, and the receiving client sends a command to the processing queue, and sends a response or a voluntary reporting command to the client.

2. Command scheduling and dispatch management module:

According to the type of the command issued by the client, it is dispatched to the corresponding processing flow, directly returns to the client to answer or waits for the delivery to return, and then sends a response to the client, or receives the active report command to the client. Current command type:

1) The commands processed by the network itself, the network element is built, broken, and pinged (including two types, one is between the collection tool and the other is the network element).

2) Collecting commands, including Qx, FTP, and TELNET. The server completes the processing and transparent transmission of command packets, such as the command to collect NEs on the Qx interface, and obtain the board information.

3) The NE actively reports the command. Generally, the command is blocked. The command is blocked according to the user's requirements and reported and reported.

3. Communication management between network elements

1) The ping packet mechanism actively sends ping packets to the client and the network element. Ping the packet upwards: guarantee the link between the client and the client; ping the packet down to ensure the link with multiple network elements.

2) Manage the establishment and authentication of multiple network elements at the same time.

3) Proactively close the connection and close the connection at regular intervals.

4, timing management

1) Timing management and connection to the collection tool.

2) Timing management and gateway connection (actively close the connection with the collection tool, you need to actively close all connections to the gateway).

3) Close the communication agent module program periodically.

5 is a schematic structural diagram of a fault information collection tool according to an embodiment of the present invention. As shown in FIG. 5, the fault information collection tool is a system for implementing communication between a client, a proxy agent, and a network element board, where the client is set by the system. , import network elements, add and execute collection and other menu items.

(1) System settings, responsible for setting the IP and port information required to connect to the agent;

(2) Importing the NEs, and importing the basic NE information reports exported from the E300/U3 network management system into the list of selected NEs, including the NE identifier, device type, subrack, and slot information.

(3) Filtering the NEs, filtering the list of selected NEs by the NE name, NE identifier, device type, and IP address;

(4) The newly added NE adds the NE to be collected to the selected NE list;

(5) Deleting the NE deletes the NE information in the selected NE list;

(6) Save the selected network element and the selected network element list to the local file;

(7) Clearing the data to clear the data of the selected network element and the selected network element list;

(8) Start collecting and start collecting the selected network elements one by one, and save the collected results to a local file;

(9) Stopping the acquisition stops the acquisition process.

This tool implements interactions with NE devices in three ways: Qx port mode, TELNET command mode, and FTP file transfer protocol mode.

Because the tool communicates directly with the device, for the convenience of processing, each component or component in the tool system uses Qx port messages to perform command and notification interactions, thereby reducing unnecessary conversion, including chaining and chain breaking with the network element device. Query the board column Tables and so on need to use Qx port messages.

The TELNET command communicates with the NE through the TELNET communication port. However, in order to be compatible with the Qx port command, the packet header is in the form of a Qx. The command parameters are the actual commands of the TELNET. You do not need to organize the board address. Different boards are only available. The TELNET command is different. The command parameters are separated by the communication agent module and sent directly to the network element through the TELNET communication port. The returned command result is then returned to the collection tool by the communication agent module.

The fault collection tool sometimes needs to download the log file from the single board device and save it to the local, which is convenient for developers and field maintenance personnel to view. In this case, the FTP file transfer protocol is needed to implement the file download function.

FIG. 6 is a flow chart of the fault information collection according to the embodiment of the present invention, in which all the board information on the network element building chain, the login network element, and the fetching network element are used to the Qx port command. The collection process of TELNET and WASON-TELNET adopts TELNET mode, and the FTP file download protocol handles the interaction with the communication device by using FTP. As shown in FIG. 6, the process includes the following steps:

In step S602, the collection is started, the network element and the collection item information set by the interface are read, and the process of connecting the communication agent Agent is completed through the IP address and port of the communication agent in the system setting, and the receiving thread is started.

Step S604, the network element is built and authenticated, and the collection tool and the communication agent module normally establish communication, and then the information and authentication information of the specific network element are established, including the Qx port construction chain and the TELNET chain, and the communication agent The modules establish connections in sequence, returning normal/exception information uniformly.

In step S606, the information of all the boards is obtained, and the information of all the boards is obtained by sending the Qx interface, and the basic information of the board obtained from the selected list of the NEs, including the NE ID and device type. IP, collection fault type, etc., save the collected data items to the TNE structure list, add the task queue, and call the entry function of the manager module.

Step S608: Matching the configuration file process, traversing the elements of the TNE structure list transmitted to the Manager, and matching the user name and password in the configuration file according to the device type of the element, and obtaining the fault command set to be delivered. .

In step S610, the command parameters are obtained, and the command collection type is determined. The loop collection process is performed for different collection types. For example, the TELNET file and the TELNET-WASON file are sent by the TELNET mode, and the FTP file is downloaded by the FTP protocol.

In step S612, the TELNET and TELNET-WASON commands are processed. Since TELNET and TELNET-WASON are both TELNET modes, the acquisition process is similar, and only the latter is described here:

The login to the WASON is the first to log in to the Sitara Networks Protocol (SNP) board. After logging in successfully, log in to the WASON. Therefore, first obtain the username and password in the TELNET node, and use the TELNET method to set the SNP username. The password is assembled into a message to the agent to issue the Qx9004 command, and then the enterksh command is issued to enter the first environment, and the process implements the SNP login.

Obtain the user name and password of the TELNET-WASON node, and use the TELNET command to deliver the user name, password, and WASON IP (IP is the proxy agent's IP address +1) and port information. The environment entered after logging in to WASON. It is unknown, that is, it may be the first environment or the second environment, so you need to issue the enterksh command again to ensure that it enters the KSH environment.

After the WASON login succeeds, the WASON command list is traversed and sent through the TELNET. If there is an enterprise in the command, the WASON user name and password must be sent again.

The client parses the packet according to the packet reported by the proxy and outputs it to the report. The file name is named according to the IP address of the network element and the suffix of *.dat, and the fault is located and tracked through the report data file.

Step S614, the FTP file download protocol processing process:

Since the client directly interacts with the agent Agent, the agent first needs to act as a client role to download the log file to the Agent agent, and then acts as an FTP server role to interact with the client. The client first establishes a socket control connection with the FTP server through the IP address and port of the network element, and then logs in to the FTP server on the proxy by sending the username and password in the FTP node in the configuration file. After logging in to the FTP server, the commands related to the FTP file download protocol are sent: Change Working Directory (CWD), TYPE I, PASV, and RETR. Then, the socket data connection is established with the server, and the file is input and output through the file. Transfer to local.

Step S616, sending a message, registering a timeout node, and blocking the thread. After all the collection items of the network element are completed, the collection tool needs to send a command to close the network element connection to the communication agent module, and the network element broken chain adopts the Qx port command 0x9001.

In summary, the embodiment of the present invention provides a new fault information collection tool. The fault information collection tool is mainly located in the network dynamic running state, static data analysis, and network hidden danger analysis, mainly for intelligent automatic network network. Health check, the scope of the test mainly includes the current network health.
