Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

The technical solution of the embodiment of the present invention is divided into three stages: 1) the network element discovery stage, that is, the network manager judges whether the network element exists through the network element discovery message; Required information; 3) In the stage of creating a network element, the network management completes the creation of the network element according to the information obtained from the network element, and brings this network element into the management of the network management.

Embodiment one

Referring to FIG. 1, the embodiment of the present invention automatically discovers network element equipment and further adds a method for network element equipment including:

101. The network manager sends a network element discovery request message to a preset IP address;

The IP address can be set according to the actual situation. For example, in the network planning, the IP addresses of some network segments will be allocated to the network element equipment in advance, and the IP addresses in this network segment can be used as the IP addresses of the newly added network elements. Actively send a network element discovery request message to each IP address in these network segments.

The sending strategy of the network element discovery request message can be set flexibly. The network management can set the sending cycle, and send to the IP address in a network segment each time, and send the IP addresses of all the network segments in turn; The sending time of the IP address is set randomly; it can also send all the IP addresses in the network segment at one time; or send some specified IP addresses separately.

In a specific implementation, the network element discovery request message may be a self-defined message, or an existing message may be used, or an existing message may be extended, for example, a ping message may be used to implement,

102. The network element device returns a network element discovery response message to the network management device;

If there is a newly connected network element device on some IP, the network element will return a network element discovery response message to the network management system, indicating that this IP has a newly connected network element device; The response message of some IP indicates that there is no newly connected network element on this IP, and then the subsequent network management can also send a network element discovery request message to this IP according to the setting to check whether there is a new network element on this IP.

The network management can build a list of IP addresses of network elements to be discovered, and manage and maintain it. When the network management finds that a certain IP address has a new network element, after the network management brings this network element into the management of the network management, it will add the IP address of this network element Exclude it from the list of network element IPs to be discovered, and no network element discovery request message will be sent to this IP next time, so as to improve the efficiency of network element discovery.

If the ping message is used in step 101, in this step, the network element will return a ping response message to the network management device.

103. The network manager sends a request message to the network element to obtain relevant information of the network element device;

In this step, the network management can notify the network element device to report its own relevant information by sending a "get network element information" request message to the network element;

104. The network element reports its own relevant information to the network manager;

The NE can carry its own relevant information in the response message of "get NE information" and send it to the network management system. The information includes: NE type, NE version, NE ID, NE IP, NE friendly name, NE geographic location, etc.;

As a more optimized implementation, in step 103, the "Get Network Element Information" request message may further include "Network Element Authentication Indication Information", which is used to instruct the network element to return the network element authentication information to the network management, so as to realize the network management. The network element is authenticated to judge the legality of the network element, and only the legal network element can accept the management of the network management. The authentication method can be set flexibly, and the basic authentication method can be used, that is, the method of user name and password; other authentication methods can also be used. In step 104, in addition to carrying the relevant information of the network element itself in the network element information response message reported by the network element to the network manager, it may also carry network element authentication information; Authentication, if the authentication is successful, execute the creation process of the network element in step 105; if the authentication fails, terminate the network element discovery process for the IP address.

Further, in step 103, the request message of "get network element information" may further include "network element identification indication information", which is used to instruct the network element to return the identification information of the network element to the network management, such as the equipment manufacturer information of the network element , the network manager decides whether to manage the network elements of the equipment manufacturer based on this information, and the authority and method of management can be set flexibly. For example, the network management can only manage network elements of certain preset equipment manufacturers, while The network elements of other equipment vendors are not managed. In step 104, in addition to carrying the relevant information of the network element in the network element information response message reported by the network element to the network manager, it also carries the equipment manufacturer information of the network element; The network element is managed, and if successful, the network element creation process in step 105 is executed; otherwise, the network element discovery process for the IP address is terminated.

105. The network management creates corresponding network element devices according to the obtained network element information;

The network management can manage the network element devices by creating corresponding network element devices according to the relevant information reported by the network elements.

Embodiment two

The difference between this embodiment and Embodiment 1 is that the network element discovery request message sent by the network management to the network element may carry the identification information of the network management or the authentication information of the network management, and only the network elements managed by the network management or the authentication passed Only network elements can be included in the management of the network management system.

201. The network management sends a network element discovery request message to a preset IP address, and the request message carries "network management identification information";

The method of sending the network element discovery request message is similar to that of Embodiment 1, and will not be repeated here;

The network management identification information is used to enable the network element to identify the network management, which can be set flexibly. For example, the identification information can be composed of "manufacturer + network management type";

The network element discovery request message may also carry "network management authentication information", which is used to instruct the network element to use the authentication information therein to authenticate the network management, and the authentication method can be flexibly set.

Further, the network element discovery request message may also carry "network element authentication indication information", which is used to instruct the network element to return network element authentication information to the network management, and the network management uses this information to authenticate the network element. The method is similar to the first embodiment, and can be set flexibly.

In addition, the network element discovery request message may also carry "network element identification indication information", which is used to instruct the network element to return network element equipment vendor information, and the usage is similar to that of the first embodiment.

202. The network element returns a network element discovery response message to the network management device;

Network elements can only accept the management of network management equipment of a specific manufacturer and network management type. After the network element receives the request information sent by the network management, it judges according to the network management identification carried in it. If it belongs to the network management management, it returns a "network element discovery response" message to the network management; otherwise, it can return a response message to the network management and indicate the reason Failed to identify.

If the network element discovery request message in step 201 carries "network management authentication information", after the network element receives it, it will authenticate the network management according to the authentication information in it, and if the authentication is successful, it will return "network element discovery" to the network management Response" message; if the authentication fails, it can return a response message to the network management and indicate that the reason is the authentication failure.

If the network element discovery request message in step 201 carries "network element identification indication information", after the network element receives it, the "network element discovery response" message can carry the network element's own identification information, and the network element identification The information can be network element equipment manufacturer information, and can also be composed of "manufacturer + network element type", which is used for the network element to indicate its identity to the network management. The network manager judges according to the identification information returned by the network element, and if it belongs to the network manager for management, execute step 203; otherwise, the device is not managed.

If the network element discovery request message in step 201 carries the "network element authentication indication information", after the network element receives it, it returns the "network element discovery response" message to the network manager, which may carry the network element authentication information. After receiving it, the network manager authenticates the network element according to the authentication information, and if the authentication is passed, executes step 203; otherwise, does not manage the device.

Through the two-way authentication or identification of the network management and network elements, the security of the system is enhanced.

If no information is returned, or an error message is returned, it means that this IP has no network element equipment or does not need to be managed. The network management starts to initiate network element discovery operations for other set IP addresses.

203. The network manager sends a "get network element information" request message to the network element to obtain relevant information of the network element;

This step is the same as Step 203 in Embodiment 1, and will not be repeated here;

204. The network element reports its own relevant information to the network manager;

Same as Step 104 of Embodiment 1;

205. The network manager creates corresponding network element equipment according to the obtained relevant information of the network element;

The network management can manage the network element devices by creating corresponding network element devices.
