Abstract

The present invention discloses a synthetic network management system based on the SNMP protocol. The synthetic network management system comprises a message dispatch processor, a failure management processor, a safety management processor, a topological management processor, a performance management processor, a configuration management processor, a northward interface processor, a system monitoring processor and a data base processor. The framework of the synthetic network management system is a star shaped communication structure which uses the message dispatch processor MDP as the center. Each processor establishes a Socket connection with MDP which is taken as a server of connection. Other processors are taken as the clients of the connection. The MDP is the core module of the network management system platform, and any program must use the MDP for communicating with other modules. The invention satisfies the requirement for the centralized management of the network device. The structural designing of loosened coupling mechanism greatly increases the independence of each module. The system is easier to be expanded and maintained along with the increasing of requirement for network management.

Description of drawings

Fig. 1 is the theory structure frame diagram of Integrated Network Management System;

Fig. 2 is Integrated Network Management System communication interface figure.

Embodiment

Below in conjunction with accompanying drawing system of the present invention is further described.

Integrated Network Management System of the present invention such as Fig. 1 comprise the message management subsystem, fault management subsystem, security management subsystem, the Topology Management subsystem, performance management subsystem, configuration management subsystem, the northbound interface subsystem, system monitoring subsystem, database subsystem.

It is the star-like communication structure at center with message management subsystem MDP that the framework of described Integrated Network Management System is one, each subsystem is set up Socket with MDP and is connected, MDP is as the server end that connects, other subsystem is as the client that connects, MDP is the nucleus module of network management system platform, and any program all must use MDP and other module to communicate.

As Fig. 2, the subsystem of Integrated Network Management System can be divided into foreground and backstage two parts, and wherein back partition comprises message management subsystem and database subsystem, and other subsystems then belong to foreground partition.Foreground partition provides the user interface of Unified Form, is integrated in the user interface system of client; Back partition uses snmp protocol and managed device to communicate, finish collection, processing and the storage of mib information, use Socket to be connected with each subsystem of foreground, receive and handle the message that the foreground sends over, inform each subsystem of foreground according to the situation transmission message of network and managed device.

When newly added equipment will put into operation, as follows with the communication process of network management system:

1) newly added equipment access network.

2) after newly added equipment obtains the IP address by DHCP Server,, initiate the management register requirement to server by the address that DNS Server obtains the network management system server.

3) the network management system server, mails to database subsystem to newly added equipment information and stores for newly added equipment is provided with initial parameter to mib informations such as newly added equipment query facility manufacturer, MAC.

4) network management system server issues northbound interface is given newly added equipment.

5) after newly added equipment puts into effect, carry out normal business function, and accept the management of network management system.

6) network management service sends message to client, more the information on the new user interface.

When foreground client has just started, enter user's login mode, security management subsystem enters state of activation.Security management subsystem sends message according to user's input information to message management subsystem MDP, send user inquiring message to database subsystem after the MDP reception information, and correlated results (whether the user exists, user right, user profile) return to security management subsystem, the operation that can security management subsystem determine the user login and can carry out according to the result.

After the user successfully logined, the fault management subsystem promptly entered active state, and no matter the user interface whether user enters the fault management subsystem.The fault management subsystem sends the state that message is obtained the current network operation to MDP, and receives the message about the network change that MDP sends at any time, and whether phase-split network abnormal conditions occur, then warns to the user if unusual condition occurs.If the user enters the user interface of fault management subsystem, display abnormality situation then, and send processing messages to the message management subsystem according to user's operation.

Behind user's logging on client, can enter the respective user interface of each subsystem of foreground according to demand, the associative operation of monitoring, browsing and be provided with.The operation of user on the user interface of foreground is packaged into message and mails to backstage message management subsystem and handle.

Security management subsystem is responsible for finishing the security control of network management system itself, the keeper can be in user interface by monitoring, browse User operation log and obtain all bookkeeping information of system, and can distribute corresponding operating right at each login user.Security management subsystem sends processing messages to the message management subsystem according to the operation on the user interface.

The Topology Management subsystem, when the user enters its user interface, immediately send the information that message is obtained current network conditions to the message management subsystem, and with modes such as topological diagram show managed devices and between link-attached state, provide modes such as subnet, view that managed object is organized, make the user understand whole network operation situation in real time by the browse network topological view.The Topology Management subsystem receives the network modification information of message management subsystem at any time, and immediate updating network topology view.

When being in the user interface of performance management subsystem, the performance management subsystem regularly sends a message to the message management subsystem, collect performance data to each managed devices, receive and handle the message that transmission is returned, carry out real-time exhibition collecting performance data by network management interface, the webmaster attendant can be monitored in real time by these data.

On the user interface of system monitoring subsystem, provide system monitoring and remote maintenance instrument.By system monitoring interface user can start, shutdown system, start, stop individual process, check the process details, the process initiation pattern is set, monitoring condition is set.The user by the system maintenance instrument in this locality or far-end can check process and database situation, detection procedure operation conditions, memory usage, hard drive space occupancy, if the database space occupancy reaches threshold values, the user will receive alarm prompt.
