The invention is implemented in a BS framework, namely a browser and server framework mode, and is a framework which is changed or improved on a C/S framework along with the rise of Internet technology. Under the structure, the user work interface is realized by a WWW Browser, a few parts of business logic are realized at a front end (Browser), but the main business logic is realized at a Server end (Server), and a three-layer 3-tier structure is formed. The B/S architecture is a network architecture mode after WEB is started, and a WEB browser is the most main application software of a client. The mode unifies the client, and the core part for realizing the system function is centralized on the server, so that the development, maintenance and use of the system are simplified. The client only needs to install a Browser (Browser), such as Netscape Navigator or Internet Explorer, and the Server only needs to install databases such as Oracle, sybase, informix or SQL Server. And the browser performs data interaction with the database through the Web Server. The precursor of SNMP (Simple Network Management Protocol) is a Simple Gateway Monitoring Protocol (SGMP) that is used to manage communication lines. Subsequently, the SGMP was greatly modified, particularly by the addition of SMIs and MIBs that conform to the Internet definition: the architecture, the improved protocol is the well-known SNMP. The goal of SNMP is to manage the software and hardware platforms produced by numerous manufacturers on the Internet.
The first data is generated by a structure of the client.
The invention mainly comprises GET and SET operation modes, because backward compatibility is supported, data is not in a database which may be just started, a data issuing process is carried out from the SET operation flow, a structure body of a client generates default data, if packaging is carried out, the interface has defined data, the structure body directly assigns the default data, otherwise, the structure body is directly reset. The client sends data to the database by the SET method, wherein the data comprises OID identifiers, structures and default data. The default data is SET data. The database is located in the server, and the database packages the data and then stores the data in the database. The database sends a notice to the network management station, and the notice network management station has a client to execute the SET operation. And after receiving the notification, the network management station judges whether the equipment is virtual equipment, if so, the operation is ended, otherwise, the network management station takes out the OID identifier and the SET data from the database and sends the SET data to the equipment in an SNMP mode.
For convenience of network transmission, the data stored in the database is provided with a packet header and a packet body, and the OID identifier and the default number are both in the packet body. The SNMP mode is an SNMP message protocol.
In the aspect of data read-back by the GET operation mode, a client requests data by the GET method, and the database packs the data and stores the data in the database. And the database sends notification to the network management station, and the notification network management station has a client executing GET operation. After receiving the notification, the network management station judges whether the equipment is virtual equipment, if so, the client side takes out the data matched with the OID identifier from the database, and if not, the network management station takes out the GET data from the database, and the network management station takes out the data from the equipment in an SNMP mode and stores the data in the database.
The invention only needs to define the structure body of the debit port and the OID identifier, the network management station can develop the function first without waiting for the operation of executing the function development after the hardware and foreground software development, thereby realizing the rapid prototype development, and having low cost and high development efficiency.
