Abstract

The present invention discloses a method for an upper level network manager to obtain messages, which comprises the steps that a shielding configuration file which comprises at least one shielding condition is arranged on the upper level network manager and sent to all lower level network managers under the management of the upper level network manager; when the lower level network managers send the messages to the upper level network manager, the messages which do not accord to all the shielding conditions in the shielding configuration file are sent. By using the unified shielding configuration which is set by the upper level network manager for the lower level network managers, the method of the present invention simplifies the repeated and complex operation that a network management personnel sets the shielding configuration for each lower level network manager, and thus, the efficiency of network management is raised.

Description

A method for superior network management to obtain information

technical field

The invention relates to network management technology, in particular to a method for an upper-level network management (UNMS) to obtain information from a lower-level network management (LNMS).

Background technique

A network management system usually manages multiple network elements (NEs), that is, network devices, in a network. A network manager maintains information about multiple network devices under its jurisdiction.

In a large network, one network manager usually cannot manage all network devices. Therefore, the network management structure needs to be layered. As shown in Figure 1, the UNMS manages several LNMSs and manages all network devices in the network through the LNMS.

When a certain LNMS needs to be managed by the UNMS, add the LNMS to the UNMS, that is, the UNMS acquires and maintains certain information contained in the LNMS, such as network device information, network topology data, alarm data, etc.

When a certain LNMS does not need to be managed by the UNMS, the LNMS is deleted from the UNMS, that is, the UNMS no longer obtains and maintains the information contained in the LNMS.

In order to synchronize the information stored on UNMS and LNMS, LNMS must report any changes in information to UNMS in real time in the form of events or alarms. Moreover, the UNMS will also poll the LNMS periodically, instructing the LNMS to report its stored information, so as to maintain the consistency of data on the LNMS and UNMS.

Since each LNMS manages multiple network devices, the information is generally large and changes frequently, so the overhead of synchronizing all information is very large. At the same time, the network administrators of the UNMS only focus on certain network devices in the LNMS, or more likely, the network administrators of the UNMS only focus on certain types of network devices under the jurisdiction of all LNMSs. For example, network management personnel only focus on monitoring IP devices such as routers and network management, but do not care about other devices.

In this case, it is redundant to obtain information from LNMS for all devices of all types. If a large amount of useless information is synchronized between UNMS and LNMS, it will increase the amount of network communication data and increase the performance overhead of UNMS and LNMS.

In order to solve the above problems, the current network administrators usually set up blocking settings for each LNMS under their jurisdiction on the UNMS side, and block the information in the LNMS that the UNMS considers useless, so that the LNMS will not report useless information to the UNMS.

However, network administrators need to repeat the above shielding operations for each LNMS under the jurisdiction of the UNMS one by one. Obviously, for network administrators, the shielding work is very cumbersome and time-consuming due to the introduction of a lot of repetitive work.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a method for UNMS to obtain information, so that the UNMS can shield useless information through simple settings.

The purpose of the present invention is achieved through the following technical solutions:

A method for obtaining information by a superior network manager, comprising:

A. Set a shielding configuration file containing at least one shielding condition on the upper-level network management, and send the shielding configuration file to all lower-level network managers under the jurisdiction of the upper-level network management;

B. When the lower-level network manager sends information to the upper-level network manager, send information that does not meet all the shielding conditions in the shielding configuration file.

Preferably, the shielding configuration file is a database file, and the database file includes three fields: a lower-level network management identifier, an equipment type identifier, and an equipment identifier,

The masking condition is a condition formed by combining the values of the above three fields.

Wherein, after step A, it further includes: adding or deleting a shielding condition in the shielding configuration file, and then sending the updated shielding configuration file to all lower-level network managers under the jurisdiction of the upper-level network manager, and replacing the original Block configuration files.

Wherein, in step B, the lower-level network manager sends information to the upper-level network manager when the equipment under its jurisdiction changes.

Wherein, in step B, the specific step of sending the information that does not meet all the shielding conditions is: the lower-level network manager judges whether the information of the changed device meets any shielding condition in the shielding configuration file, and if yes, then no Send the information to the upper-level network manager; otherwise, send the information to the upper-level network manager.

Wherein, in step B, the lower-level network manager sends information to the upper-level network manager after receiving the information reporting instruction message from the upper-level network manager.

Wherein, in step B, the specific step of sending the information that does not meet all the shielding conditions is: the lower-level network manager sends all the information contained in it that does not meet all the shielding conditions in the shielding configuration file to the upper level network management.

Preferably, the information is any one or a combination of any of equipment information, network topology data and alarm data.

It can be seen from the above technical solutions that the method of the present invention uniformly sets the information to be shielded on the UNMS, and the LNMS reports useful information according to the unified shielding settings. It avoids the complex and tedious work of network administrators performing shielding settings for each LNMS in the prior art, greatly reduces the workload of network administrators, and improves the efficiency of network management.

Moreover, the method of the present invention provides a new idea for network management. By setting unified management rules and issuing them to lower-level network managers, the upper-level network management can manage the network conveniently and avoid management errors caused by cumbersome operations.

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 and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The present invention provides a simplified method for UNMS to obtain information from LNMS. A shielding configuration file containing at least one shielding condition is set on UNMS, and the shielding configuration file is sent to all LNMSs under its jurisdiction. When LNMS reports information to UNMS , report information that does not meet all blocking conditions.

Fig. 2 is the flow chart of the method for UNMS to obtain information from LNMS according to a specific embodiment of the present invention, in this embodiment, UNMS manages four types of network devices: Devtype1, Devtype2, Devtype3 and Devtype4, now, the network administrator needs Browse and manage network devices of type Devtype1 and Devtype2. As can be seen from Figure 2, the process of UNMS blocking useless information includes the following steps:

Step 201: Setting a shielding configuration file on the UNMS, the structure of the shielding configuration file is shown in Table 1.

Table 1

LNMS logo Device Type Identification Equipment Identity 0 Devtype3 0 0 Devtype4 0

Preferably, the shielding configuration file is a database file. As shown in Table 1, the shielding configuration file contains three fields: LNMS identifier, device type identifier and device identifier. If the LNMS ID of a masking condition is A, the device type ID is B, and the device ID is C, then the masking condition indicates that the information of the device C whose device type is B in the LNMS whose ID is A is blocked. If a field value is 0, it means unlimited.

In this embodiment, the shielding configuration file includes two shielding conditions, wherein the LNMS identifier of one shielding condition is 0, the device type identifier is Devtype3, and the device identifier is 0, which means shielding all devices whose device type is Devtype3 in the LNMS; in addition The LNMS identifier of a shielding condition is 0, the device type identifier is Devtype4, and the device identifier is 0, which means that all devices whose device type is Devtype4 in the LNMS are shielded.

Step 202: The UNMS sends the shielding configuration file to each LNMS currently under its jurisdiction.

Step 203: When the information on the LNMS changes and the change information needs to be reported to the UNMS in real time, the LNMS judges whether the change information meets any masking condition in the masking configuration file, and if so, executes step 204; otherwise, executes step 205. Report the change information to UNMS.

Step 204: the LNMS does not report the change information to the UNMS, and then ends.

Step 205: the LNMS reports the changed information to the UNMS, and then ends.

In this embodiment, for all LNMSs, no information about all devices whose device types are Devtype3 and Devtype4 is not reported.

The above is an embodiment to illustrate the specific implementation process of the present invention. In other embodiments of the present invention, when the UNMS polls the LNMS, the LNMS also needs to report information to the UNMS. The specific process includes the following steps:

Step 1: When the UNMS polls the LNMS, it sends an information report indication message to the LNMS.

Step 2: The LNMS reports to the UNMS the information that does not meet all the shielding conditions in the shielding configuration file among all the information it contains.

In other embodiments of the present invention, when an LNMS is added to the UNMS, if there is no special shielding setting for the LNMS, the shielding setting file is not updated; if there is a special shielding setting for the LNMS, then the shielding setting file is updated , and then deliver the updated shielding configuration file to all LNMSs. For example, when UNMS adds an LNMS identified as M, if all information of M needs to be shielded, a shielding condition is added in the shielding configuration file. At this time, the structure of the shielding configuration file is shown in Table 2.

Table 2

LNMS logo Device Type Identification Equipment Identity 0 Devtype3 0 0 Devtype4 0 m 0 0

In the added shielding condition, the LNMS identifier is M, the device type identifier is 0, and the device identifier is 0, which means that all devices of all types in the LNMS with the identifier M are shielded.

In other embodiments of the present invention, when the UNMS needs to change the shielding configuration, such as adding or deleting shielding conditions, it updates the shielding configuration file, and then sends the shielding configuration file to all LNMSs.

It should be understood that the present invention is an improvement to the traditional network management method. By setting unified management rules, convenient management of the network can be realized, and network management errors caused by repeated and complicated operations can be avoided. Therefore, the present invention is not limited to setting uniform shielding rules, but can also be applied to other management rules.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
