Background technology
Along with the continuous development of network technology, the application and the scale of network constantly enlarge, and the information that network management system need be safeguarded is also in continuous increase.Network management system mainly be at the network equipment monitor, configuration and failure diagnosis.Major function has automatic topological discover, Remote configuration, performance parameter monitoring and failure diagnosis, but also will be to outside webmaster (as the webmastering software of higher level's webmaster, third party producer) open interface, so that outside webmaster can obtain data that this network management system handles etc. by this interface.
Especially, along with the user is strong day by day to the demand of " centralized monitor, centralized management ", northbound interface (Northbound Interface) unit that just needs the lower net guard system to provide, the northbound interface unit that outside webmaster provides by this network management system obtains the data of this network management system inter-process.A typical lower net guard system can be divided into NE-level network management system (EMS) and sub-network level network management system (SNMS).Though SNMS and EMS all provide the northbound interface unit,, be the requirement that realizes managing concentratedly between the multilevel network management system, general by SNMS EMS the convergence earlier provides this lower net guard system unified northbound interface unit by SNMS to outside webmaster again.
But, present network size is all very big, has the multilevel network management system in the network, and the network management system of different layers all has the northbound interface unit that oneself is developed, make the northbound interface unit of existing multilevel network management system mainly have the defective of consistency difference, mainly show as follows:
At first, the northbound interface unit of different layers network management system may be developed with different software developers by different vendor, the interface standard that causes the northbound interface unit of different layers network management system to be adopted is difficult to consistent, so that consistency is relatively poor between the northbound interface unit of multilevel network management system;
Further, even the network management system of different layers provides the northbound interface unit according to same standard, but, in the northbound interface unit of different layers network management system, the developer is according to the hobby of oneself, and is inconsistent to the defined form of expression of same object (or object oriented) in the network, causes the information of different layers same object that network management system is returned to exist the form of expression inconsistent, and the shortcoming of information content unanimity is difficult to meet consumers' demand.Such as, SNMS and EMS externally provide the northbound interface unit according to TMF8.14 2.0 standards, when receiving outside webmaster, SNMS and EMS inquire about the service request of all veneers (CircuitPack) information under all network elements (ME), because in SNMS and EMS northbound interface unit separately, inconsistent to the object oriented of veneer definition respectively, cause SNMS and EMS respectively in the solicited message that outside webmaster returns, the object oriented of detailed single board information is inconsistent, and the content unanimity of information, increase the complexity of process information like this to external network, also be difficult to satisfy the user provides unified northbound interface unit to the different layers network management system demand;
In addition,, the focal point of information in the network also is not quite similar, therefore, in fact is difficult to guarantee the northbound interface unit complete unity of different layers network management system because that the different layers network management system stresses in network is professional different.Such as, SNMS pays attention to the management of teleservice, and EMS more pays close attention to the professional management in single station, therefore, even SNMS and EMS externally provide northbound interface according to TMF8.14 2.0 standards, when the service request of all single board information under the network element in the outside webmaster requester network, in fact SNMS and EMS are difficult to guarantee to return in the solicited message, have consistency for the detailed data of all single board information under the unified network element.
And, the network management system of different layers needs alone, safeguards exploitation northbound interface unit, such as, SNMS and EMS externally provide northbound interface according to TMF8.14 2.0 standards, if the service of all single board information under all network elements in the requester network is provided for outside webmaster, so, SNMS needs according to the query interface in the stock control exploitation northbound interface unit of oneself, and EMS needs too, therefore, develop, safeguard that the northbound interface unit of different layers network management system need expend huge human and material resources and financial resources, increase the operation costs of network.

As shown in Figure 1, be the configuration diagram of multilevel network management of the present invention system.Compared with prior art, in the multilevel network management of the present invention system, remain and by SNMS EMS is restrained earlier, and include a northbound interface unit among SNMS and the EMS; Different is that in the present invention, the northbound interface unit of SNMS passes through the northbound interface unit of EMS.
Described transparent transmission is meant that described SNMS is to issue described EMS between after the EMS naming method through simple conversion to object oriented in the extranets guard system, and with object oriented simple conversion in the described EMS return data for the SNMS naming method is back to described extranets guard system.
Described extranets guard system be meant need be from this multilevel network management system adjacent two-stage network management system obtain the network management system of data.
Described SNMS comprises:
Message management mainly is responsible for, such as functions such as subscription, forwardings in message management unit 120; Accept the request of the extranets guard system transmitted described northbound interface unit 110, and the service unit that calls SNMS inside responds this request;
Data on stock library unit 130 carries out stock control to storage in the network;
Functions such as circuit search, circuit inquiry, circuit creation, circuit deletion mainly are responsible in configuration service unit 140;
Performance service unit 150 mainly is responsible for functions such as performance reports, performance queries;

Safety management mainly is responsible in alerting service unit 170, function such as checks such as alarm report, acknowledged alarm, alarm inquiry, alarm deletion, alarm;
Other service units 180 mainly according to user's request exploitation, are responsible for some simple task, such as log management etc.
Wherein, see shown in Figure 2ly, the northbound interface unit 110 of described SNMS specifically comprises as follows:
Serve administration module 1110, be used to accept the request of extranets guard system, and webmaster northbound interface at the corresponding levels and subordinate's webmaster northbound interface are divided in this request according to the type or the object of request.
Transparent transmission administration module 1120, accept described serving and distribute subordinate's webmaster northbound interface request that submodule is distributed described in the administration module 1110, determine that according to the object of this request or type this asks pairing EMS, and subordinate's webmaster northbound interface is passed through the northbound interface unit 210 of this EMS.
Described webmaster northbound interface at the corresponding levels is a network layer interface, and described subordinate webmaster northbound interface is the Network Element Layer interface; The request of described webmaster northbound interface at the corresponding levels is the network layer interface request, and the webmaster northbound interface request of described subordinate is the Network Element Layer interface requests.
Particularly, the described administration module 1110 of serving comprises storage regulation management submodule, judges submodule and distributes submodule, described storage regulation management submodule is used to set up a cover criterion, according to object or type interface storage in the network is divided into 2 classes: network layer interface storage and Network Element Layer interface storage; Described judgement submodule is used for request object or the type according to outside webmaster, and compare with the criterion of setting up in the described northbound interface unit, thereby judge that this request is the network layer interface request, or the Network Element Layer interface requests; The described submodule of distributing is used for judged result according to described judgement submodule, the network layer interface request is distributed to described task management module 1130 handles, and the Network Element Layer interface requests is distributed to described transparent transmission administration module 1120 handles.
Below in conjunction with Fig. 3,, further illustrate described classifying rules of serving docking port in the administration module 1110 or request with the classification schematic diagram of network stock in TMF814 2.0 standards.
Rule according to whether relating to a plurality of network elements (ME) is divided into two classes to network stock in M814 2.0 standards: network layer storage and Network Element Layer storage.Because there is more than one network element, be the necessary condition that constitutes the network layer storage, otherwise, in network, only there is a network element, then the storage in this network all is the Network Element Layer storage.Wherein, the network layer storage comprises subnet (Subnet), subnet selection circuit (SNC) and topological connecting circuit (TL); The Network Element Layer storage comprises network element, and the many structures under the network element, such as protection group, veneer etc.
It is network layer storage and Network Element Layer storage that network stock is set, be in described northbound interface unit 110, default corresponding criterion, so that the interface correspondence in this multilevel network management system is divided into network layer interface and Network Element Layer interface, so that described northbound interface unit 110 judges that the request from the extranets guard system still is the Network Element Layer interface requests for the network layer interface request.
SNMS passes through EMS to the Network Element Layer interface, corresponding Network Element Layer interface requests from the extranets guard system, and SNMS passes through the EMS processing and gets final product.Such as, among the TMF814 2.0IDL, all physical port (PTP) interfaces under network element of extranets guard system inquiry, because this PTP interface only relates to Network Element Layer storage ME and PTP, so, SNMS just directly passes through this PTP interface the corba interface of EMS, is responsible for handling this request by EMS and gets final product.
Certainly, can not pass through EMS, need SNMS oneself exploitation for network layer interface.Such as, among the TMF814 2.0IDL, the online all SNC circuit of son of extranets guard system inquiry are because the division of SNMS and the subnet of EMS own just is not quite similar, in addition, because the EMS managerial ability is limited, some SNC circuit can not form a complete SNC circuit in EMS, only could form a complete SNC circuit in SNMS, therefore, this type of information can only obtain from SNMS itself, so corresponding network layer interface also need be developed by SNMS.
Fig. 4 has provided principle schematic of the present invention.
At first, the described northbound interface unit 110 (step s310) of configuration SNMS; Be specially: in the described storage regulation management submodule of the described northbound interface unit 110 of SNMS,, set up the criterion that a cover is divided into network interface network layer interface and Network Element Layer interface according to the sorting criterion of described storage;
Secondly, a request from the extranets guard system (step s320) is accepted in described northbound interface unit 110, and judges that this request is the network layer interface request, or Network Element Layer interface requests (step s330); Be specially: described object or type of serving the described judgement submodule of administration module 1110 according to request, compare with the criterion of setting up in the described storage regulation management submodule, thereby judge that this request is the network layer interface request, or the Network Element Layer interface requests;
Once more, processing of request; Be specially: according to the judged result of described judgement submodule, if described judgement submodule judges that described request is the Network Element Layer interface requests, then this Network Element Layer interface requests is distributed to described transparent transmission administration module 1120 by the described described submodule of distributing of administration module 1110 of serving, by this transparent transmission administration module 1120 the Network Element Layer interface is passed through the described northbound interface unit 210 (step s351) of EMS, and handle this request (step s352) by EMS; If described judgement submodule judges that described request is the network layer interface request, then this network layer interface request is distributed to described task management module 1130 processing, and specifically handles this request (step s341) by SNMS by the described submodule of distributing.
