Description

Network operation and maintenance system and its compatible network management system message change method

Technical field

The present invention relates to the field of communications technologies, and in particular, to a network operation and maintenance system and a method for changing a message of a compatible network management system.

Background technique

The network management system may have different versions in different places, and the network operation and maintenance system (higher-level network management system) needs to access these different versions of the network management system to obtain data (to achieve intelligent health check on these network management systems). As for how to communicate between network operation and maintenance systems and different network management systems, this problem has a good solution at present - communication through Abstract Syntax Notation (ASN) messages.

In the actual use process, we also found another problem, that is, the ASN packet change problem, specifically, a certain function module of the network management system is implemented in the A version with the message a1, in the B version. At the time of the message a1, a field is added, and both the A and B versions are used, and the network operation and maintenance system T needs to access the versions A and B to acquire data. How is the T compatible with the difference between the A and B versions of the message change? The usual treatment is:

1. Two versions of T are provided, corresponding to two versions of A and B respectively;

2. T only provides one version, but there are two sets of ASN packets. Before accessing A and B, there are different options for users to choose. Users need to specify whether they are currently accessing version A or version B, thus confirming the corresponding options. T loads different ASN packets according to user options. The two ASN packets are the same except for the a1 packet.

Although the above method 1 can solve the problem, providing multiple versions of T makes maintenance troublesome. Although the method 2 has only one version T, two sets of ASN packets are required. Except for the message a1, other packets are duplicated, resulting in a large amount of redundancy. Moreover, the operation requires the user to confirm whether the access is A version or B version. It is troublesome. Once the network management system version is more, how to confirm the version will be a very troublesome thing. Once the error is confirmed, the network management system may be connected. Failure, etc.

Specific embodiments of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

Embodiment 1

As shown in FIG. 1 , a method for changing a packet of a network operation and maintenance system compatible with a network management system is provided in the embodiment of the present invention. After receiving an ASN message sent by the network management system, the method includes:

Step 100: Obtain a version of the network management system.

Step 101: Obtain, according to the version, an identifier of the first ASN packet of the network management system that has a different field from the corresponding standard ASN packet.

Step 102: Create a first ASN packet, and process the same field value of the first ASN packet and the corresponding standard ASN packet according to the same processing procedure as the standard ASN packet.

The invention can be compatible with the packet difference of the network management system of different versions. After receiving the ASN packet sent by the network management system, the version of the network management system is automatically obtained, and no manual intervention is required. When the ASN packet used by the network management system changes, the same field value of the ASN packet and the corresponding standard ASN packet are processed according to the same processing procedure as the standard ASN packet, and the application layer is not added. Encoding does not cause a lot of redundancy in the message. At the same time, only one operation and maintenance system is needed to maintain different versions of the network management system to facilitate system maintenance.

Wherein the first ASN packet identifier _may be represented by a, the corresponding standard message identifier ASN may be represented by a. The first ASN message a ₁ may be increased or decreased with respect to the standard ASN message a. For example, the standard ASN message a includes two fields a ₀₀ and a ₀₁ , and the first ASN message a ₁ includes a ₀₀ , a ₀₁ , a ₀₂ three fields.

After obtaining the version of the network management system, in order to obtain the identifier of the first ASN packet of the network management system according to the version, the version of the network management system, the version corresponding to the version, and the standard ASN may be configured in advance on the network operation and maintenance system side.

The technical solution of the present invention is that the first ASN packet name of the different version of the network management system is different from the corresponding standard ASN packet. The specific ASN packet and the standard ASN packet have different fields, for example, the first ASN. When the message is added to the standard ASN packet, the automatic compatibility of the packet difference is achieved.

Through the above steps, the processing of the second ASN packet of the network management system can be completed by the process of processing the corresponding standard ASN packet, and the packet redundancy is not caused.

In a specific embodiment, step 102: ASN creating a first packet of _a same as the corresponding standard message ASN ASN first packet field values a, be processed in accordance with the same standard ASN message processing flow ,Specifically:

For example, when the standard ASN message a includes two fields a ₀₀ and a ₀₁ , the first ASN message a ₁ includes three fields a ₀₀ , a ₀₁ , and a ₀₂ . ASN first copy packet in a ₁ a _00, ₀₁ a value of two fields, the packet is copied to a standard ASN in a _00, a ₀₁ two fields, is a recursive process copies, until a copy of the required layers _The final copy of the two fields ₀₀ and a _{01 is} completed. The standard ASN message a is then processed, and the a ₀₂ field is not processed. Since it is only a copy of the value, there will be no duplication and no redundancy of the message.

Below is a version of the network management system A, a first packet identifier ASN used is a _1, the corresponding standard message ASN identified as a, the method specifically described in the embodiment of the present invention, comprising:

The first packet ASN step S1, the network storage system version A, version A with the corresponding standard and ASN have different packet identification field mapping relationship between a standard and _an identifier of a packet ASN, specifically :Aaa ₁ ;

Step S2: After receiving the ASN packet sent by the network management system, obtain the version A of the network management system;
