When using the system, keeper is added to all-network equipment 10 by the network management device 20 first The management high in the clouds 30, the management high in the clouds 30 sets all map networks by the automatic or manual of geography information module 32 Standby detailed geographical information Store is in the database management module 33;Keeper is again by the basis of the Network conf iotag. module 31 Practical business has configured the corresponding network equipment, and simultaneously by presetting abnormality processing strategy in the exception processing module 34 Or intelligent memory module 341, intelligent extraction module 342, intelligence learning of the exception processing module 34 in own module What is generated after module 343, intelligent analysis module 344 automatically processes strategy to process exception;Network equipment A is such as set to be set with network Standby B backups each other, and sets network equipment A described in the rear monitor in real time of the exception processing module 34 and network equipment B.Work as monitoring Exception, 34 pairs of database management modules 33 of the exception processing module are occurred in that to the network equipment A or network equipment B Carry out history matching extremely or real-time intelligent analysis generation abnormality processing strategy.If matching history exception, using directly tune Take identical abnormality processing strategy, save the process for reanalysing calculating, more acceleration with it is efficient;If there is new exception, from The new abnormality processing strategy of dynamic generation, such as being already provided with network equipment A and network equipment B is set to backup mutually, such as The network equipment B replaces the network equipment A or described network equipments B replacements network equipment A and is operated.Herein it Afterwards, the exception processing module 34 can actively the abnormal alert receipt module 351 for passing to the alarm module 35, the alarm Receiver module 351 is understood by alert notice module by modes such as short message, mail, prompt tones warning message after receiving exception Keeper is notified, while warning message is stored to the database management module 33, side by the alarm statistical module 353 Just next time directly transfer.
In the present embodiment, the network management device and the network equipment are realized in the management high in the clouds 30 using soap protocol 10 two-way communication.Soap protocol (Simple Object Access Protocol), is a kind of protocol specification of exchange data, is a kind of light weight , the simple, agreement based on XML (a subset under standard generalized markup language), it is designed to exchange knot on WEB Structure and solidification information, gathers around and has the following advantages:
Scalability, soap protocol need not interrupt existing application program, and SOAP clients, server and agreement itself are all Can develop, and soap protocol can admirably support the architecture of intermediate medium and stratification;
Interaction is simple, and client sends a request, calls corresponding object, then server returning result, and these disappear Breath is XML format, and is packaged into the message for meeting http protocol, therefore, it meets any router, fire wall or agency The requirement of server;
Complete and manufacturer is unrelated, and soap protocol can be relative to platform, operating system, object module and programming language independence Realize, in addition, the parameter selection of transmission and language binding and data encoding is determined by concrete implementation;
Unrelated with programming language, soap protocol can be completed using any language, as long as client sends correct SOAP request (one suitable parameter of transmission is to a far-end server for reality), therefore, soap protocol does not have object model, Application program can be bundled in any object model;
Unrelated with platform, soap protocol can be in any operating system without changing the normal operation in ground.
Cause that user can log in management in any place, in any operating system using the network management system of soap protocol High in the clouds, network management system is accessed, realize simultaneously Distant supervision and control all-network equipment, range of management in the network management system Extensively, real-time is high.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as Protection scope of the present invention.
