For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is further detailed explanation.
The invention provides a kind of extendible network management system, in the SNMP network management, to act on behalf of Agent mutual with residing in SNMP in the managed devices through management information bank MIB for snmp management station Manager, the described managed devices of SNMP proxy management, and in equipment local network side or Upper NM Station center a configuration management system CMS is set, this system comprises Configuration Manager, device management module, connection management module and showing interface module.
Configuration Manager identifies the configuration data of equipment according to certain rule, and provide a cover to describe the interface of identification data, the equipment that inserts need be according to describing the configuration data of oneself based on the interface of MIB and formulation configuration file and description being deployed in the native system, and Configuration Manager just can be included this equipment in configuration management.Above-mentioned process has all realized that with equipment side needing the Agent of the configuration feature of management is prerequisite.
As a certain equipment of being managed of SYSID unique identification among Fig. 2, the configuration item of the equipment of being managed can be divided into the big class of a plurality of functions according to function, can divide a plurality of function subclasses under the big class of each function again, divide the functional tree that forms this kind equipment so layer by layer, each leaf node on the functional tree identifies by FuncID.The leaf node of this functional tree is the set or the form that can comprise the multirow record that have comprised a plurality of atom configuration items.And the atom configuration item is a data unit that concrete implication is arranged, can represent by simple data type, just the least unit that will manage of this configuration management system, for example IP address, the port of system.Owing to usually above-mentioned atom configuration item is defined as scalar in MIB, so the leaf node on the functional tree of equipment may be the set of a scalar, also can be a form, is defined as the table amount among the MIB.Based on above-mentioned function items layering division rule, by the OID definition of mib file to scalar sum table amount, configuration management system can be by any configuration item that comes the unique identification configuration management system to be managed by SYSID, FID, OID, and wherein FID is that FuncID on the critical path of leaf node on the functional tree connects to form.For example the system banner SYSID of XX equipment is SYS01, its configuration item is divided into three major types such as Func1, Func2, Func3, wherein Func3 comprises 2 SNMP scalar configuration item, is respectively system ip address (OID:1.1.1.1), system's listening port (OID:1.1.1.2).Then by SYS01-Func3-1.1.1.1 just can be unique the IP address of this system of sign.
According to above-mentioned configuration data sign, the main work of Configuration Manager is the correspondence of finishing the OID of configuration data on device instance configuration item to the configuration-system, and safeguards this mapping relations.Configuration Manager upwards provides these data to be used to generate configuration interface to boundary layer; When the user makes amendment to certain configuration item by configuration interface or inquires about, Configuration Manager parses the configuration item OID on corresponding equipment example ID and the device instance, calls link block and sends SNMP and ask to inquire about or be provided with specified configuration on the designated equipment.
Configuration Manager distributes special deployment district to be used for configuration describing document and interface document that storage equipment is disposed, from then on regional loading equipemtn configuration describing document when module initialization, create customization detection task during module initialization simultaneously, detection of dynamic is disposed the equipment disposition description document in district, the rule definition that configuration describing document provides according to configuration-system the information that needs of the Configuration Manager such as function items of device type, equipment side.The workflow of Configuration Manager loading equipemtn configuration describing document and interface document as shown in Figure 4,
Each device type of being managed has an independent catalogue in the deployment district, at least there is a device configuration file in the catalogue, comprise the device type sign, comprised configuration describing document, MIB interface document and other files that need customize of this equipment in its subdirectory.When the Configuration Manager initialization, detect all devices catalogue of disposing the district, the discovering device sign, load configuration information, this equipment of sign in device configuration file and interface document that loads has successfully loaded success, loads failure and then status indicator is failure.Have new facility inventory generation or content update because follow-up this is disposed the district, regularly the detection task can regularly read device configuration file and the interface document under each facility inventory, finds to have the equipment that loads sign to be reloaded as new equipment.According to above-mentioned flow process, list of devices that the Configuration Manager saved system is up-to-date and configuration describing document and interface document are as the basis of interface display layer and subsequent configuration.Finish mapping and the maintenance of equipment according to the configuration data sign to the configuration item of configuration-system;
Device management module is used to safeguard the device instance tabulation of described CMS and the device type that described CMS supports.One of function of device management module is exactly the device instance tabulation of maintain configuration system management.In managed networks, may there be the situation of deployment with a plurality of examples of a kind of equipment, even certain device type has only an example, need also to know that the address of equipment can be connected up by agreement with the port configuration management system, so configuration management system needs service equipment type corresponding equipment example list.Another function of device management module is the device type that the maintain configuration system supports, the configuration describing document and the interface document of fetch equipment in system configuration loading procedure or timing detection task, in these files, defined the type identification of equipment, this type sign should should be identical with the ident value of system node among the equipment side MIB, think that device type does not match if this value is inequality, will not add this equipment to configuration management system CMS.
The connection management module is used for providing the interface that sends the SNMP request, receives SNMP response and alarm to Configuration Manager and device management module;
Showing interface module, slave unit administration module read the tabulation of up-to-date device type, read the functional tree of described device type correspondence, systematic function configuration interface from Configuration Manager.
The system of having described in Configuration Manager can be by the device category of the current support of testing mechanism maintenance system and the configuration describing document and the interface document of every kind of equipment, the configuration describing document of equipment comprises the function items that equipment need manage, the organizational form of function items, configuration item and the corresponding resource that function items comprises, and equipment side also provides the mib file of configuration item simultaneously.Showing interface module slave unit administration module reads the tabulation of up-to-date device type, reads the functional tree of every kind of device type correspondence from Configuration Manager, generates and is convenient to user's navigation function configuration interface; When the user found the function subitem of oneself being concerned about according to device type, function items, the showing interface module was according to the device type at function subitem place, and the slave unit administration module gets access to this type list of devices of the current management of system, is shown to the interface; Generate simultaneously the configuration interface of this function items according to the mib file of the configured list of this function correspondence in the Configuration Manager and equipment.
For comprising all is the function items of scalar data, and configuration interface provides inquiry, retouching operation, and the interface of modification generates according to the type and the scope of the configuration item that this function items in the mib file comprises, and is revising the logic verify that carries out input value when submitting in view of the above; Function items for the table type, being divided into Static and Dynamic Tables handles: the processing of static table is with the processing of scalar function items, the function items that difference is to comprise scalar has only a line item and shows data the multirow record is arranged, and the static table data are also only supported inquiry and revised; For the function items of corresponding dynamic table, the interface also provides except inquiry and retouching operation are provided to be increased and deletion action.
Because all configuration items of equipment can come unique identification by SYSID+FID+OID, the configuration interface that generates according to top rule can satisfy all requirements.But each equipment has various special demand in the reality when showing interface, therefore the showing interface resume module provides outside the general interface model, also allow the equipment defined interface, specify in the device description file of Configuration Manager management at these customization interfaces, integrated by the displaying interface module according to configuration, the unit at this customization interface is the leaf function in the functions of the equipments tree, when the user navigates to the function items of customization on the interface, the configuration interface that the configuration interface framework provides presentation device.
Based on above-mentioned configuration management system, as shown in Figure 3, support the equipment of snmp protocol will insert configuration management system, carry out the configuration management of equipment, needed step is as follows:
Steps A: the network management personnel wishes to include the equipment that machine room increases newly in configuration management system, at first obtains the standard network interface tube file of new equipment, analyzes which OID and need include the configuration management system management in;
Step B: these configuration items are organized into functional tree according to the form of expecting on the interface that represents, and the formation rule of functional tree is referring to the introduction of Configuration Manager;
Step C: whether each leaf function items of analytic function tree needs to be configured the customization at interface.For the configuration item under the function items all is that the situation of scalar does not generally need to customize, and each configuration item inquiry and being provided with separately gets final product; For the table data, have incidence relation between configuration item or between function items, General Purpose Interface can not satisfy this type of demand, need carry out the specific customization at interface.
Step D: the function items of particular interface demand is arranged, need carry out this step.This step requires the customization personnel that certain Web interface and software development experience are arranged.The customized development personnel are according to the specific demand exploitation Web interface of oneself, and the element that needs in the interface to inquire about and be provided with can correspond to some OID among the MIB of new equipment.When the page was submitted inquiry to, the customized web page tissue was wanted the OID of searching elements, called the open query interface of configuration-system, and interface returns Query Result; When customized web page was provided with some OID, the OID value of collecting on OID that submission will be provided with set and the interface was called the API that is provided with that configuration-system provides, and to the equipment side write data, and returns response.
Step e: no matter be the general page or customized web page, all need to provide the description document of configuration feature item, this file has comprised the information of Configuration Manager, showing interface module needs
Step F: can by manually add, file is uploaded, HTTP uploads mode in the deployment catalogue of configuration management system, includes configuration describing document, customized web page and deployment of components in the configuration management system management.
Step G: behind the deployment success, the network management personnel can be by the newly-increased network equipment of configuration management system management.
From above flow process as can be seen,,, only need provide configuration file just can include equipment in this configuration management system, equipment is managed maintenance if having only the demand of General Purpose Interface for the equipment of supporting snmp protocol.
But above-mentioned only is better embodiment of the present invention; be not to be used to limit protection scope of the present invention; any those skilled in the art of being familiar with will be appreciated that; all within the spirit and principles in the present invention scope; any modification of being done, equivalence replacement, improvement etc. all should be included within the scope of the present invention.
