Description
Technical field
The present invention relates to the field of network management of communication system, relate in particular to a kind of method and device of realizing northbound interface.
Background technology
Along with the high speed development of telecommunication industry, the scale of communication network constantly enlarges, and device category and networking mode also become increasingly complex and variation.At present; The equipment of each operator is made up of the equipment of how tame different vendor often jointly; All there is Element management system (the Element Management System of own equipment in each manufacturer; EMS), but unified interface information model and data target can't be provided between these Element management systems, the centralized management of network has been brought difficulty.
To the problems referred to above; In order to realize unified management to the whole network; The hope of office side can on the basis of the network management system of disperseing at present, set up comprehensive NMS (Network Management System, NMS), this just requires each manufacturer in own distinctive Element management system; Unified interface towards integrated network management system is provided, i.e. northbound interface.Northbound interface can shield the otherness between each Element management system and the equipment, realizes the integrated management to different vendor, different network type, reduces the complexity of network management.
Common northbound interface agreement has CORBA (Common Object Request Broker Architecture), FTP (FTP), XML (SOAP/Web Service), SNMP (Simple Network Management Protocol) and TL1 (transaction language 1) at present.Wherein:
CORBA is the OO application program system standard by a kind of standard of OMG OMG formulation.Form by Object Request Broker (ORB), objects services, communal facility, domain interface and application interface.Its core is the ORB of Object Request Broker, and ORB provides a kind of mechanism, through this mechanism, and request of sending that object can be transparent and reception response.The shortcoming of corba interface is too huge and complicated, and butt joint debug difficulties and autgmentability are poor, and when interface changed, the butt joint both sides will recompilate, and development cost is high.
The FTP interface is meant webmaster regularly with the information spanned file of needs, and comprehensive network management obtains these files through File Transfer Protocol and resolves according to the form of appointment.The FTP interface mode is suitable for the situation that the downward layer of upper strata webmaster webmaster obtains big data quantity, is inappropriate for the situation that real-time is had relatively high expectations, and also is not suitable for the situation that the upper strata webmaster is operated EMS.
XML (SOAP/Web Service) be a kind of light weight, simple, based on the agreement of XML, it is designed to the structurized information of exchange on WEB.The shortcoming of XML interface is that redundant data is big, and efficiency of transmission is lower, and the XML that uses in the message must do parsing at every turn, and analyzing efficiency is relatively low, and control of authority is cumbersome.
SNMP is the NMP that is overlapped based on UDP by one of ietf definition, is simple and easy to usefulness, is actual network management industrial standard.SNMP manages based on the Manager/Agent model, and (Management Information Base MIB) carries out information interaction with relevant command set, and SNMP Trap is that the message in the snmp protocol initiatively reports mechanism to adopt management information base.The shortcoming of SNMP interface is that comprehensive network management NMS can not directly carry out the order issuing service operation of CLI (Command Line Interface, command line interface) mode through EMS.At present traditional command line interface CLI has become the interface that most of equipment vendors generally support, therefore adopting the mode of command line interface that network element is configured is the mainstream technology means that present network management system adopts.
TL1 is a kind of telecommunication administration agreement of the standard that connects based on TCP, and the TL1 butt joint is simple, and debugging is convenient, favorable expandability, easy to understand and use.In order to support integrated network management system to carry out sending down service; TL1 northbound interface need be provided in Element management system, and TL1 northbound interface is used to receive the TL1 command request on the one hand, is used to accomplish the adaptive and transfer process that TL1 orders concrete CLI order on the other hand; Realization is mutual with concrete network element; Operator adopts the TL1 agreement to carry out sending down service becomes first-selection at field of telecommunications, and from the operating position of reality, TL1 has become the most widely used northbound interface agreement at present.
Existing TL1 northbound interface characteristics of development is: to each TL1 order; Developer's (application side) will pay close attention to the handling problem of TL1 agreement itself; Comprise the parsing of TL1 protocol format, the mapping that TL1 orders concrete device command, the packing of message response form and returning etc.Therefore this development mode has been brought following problem:
(1) the exploitation threshold is higher, and developer's focus is too many, and the developer not only will pay close attention to service logic itself; Also to pay close attention to the parsing of TL1 protocol information; The other problemses such as authority, security control and daily record of TL1 order, therefore, this development mode is unfavorable for the separation of focus; The efficient of exploitation is low, safeguards also relatively difficulty.
(2) traditional T L1 northbound interface lacks the centralized control to TL1 message.Since developer's otherness itself, the different style that its message is returned, and the consistency of message structure is relatively poor.
(3) extensibility is not enough, and when the network element version upgrading perhaps increased a kind of network element of newtype newly, the northbound interface program of webmaster must be upgraded synchronously.
(4) automaticity of TL1 Message Processing is not high.Existing development mode uses the different service process class to handle different TL1 orders mostly, does not set up automatic mapping and composition mechanism that TL1 orders concrete CLI order, and dynamic adaptable is relatively poor.

Control of authority file with following XML is that example specifies.
In the superincumbent control of authority file, two users of admin and test have been set up.
Alloperation=" true " expression admin user can issue the TL1 order that all northbound interfaces are supported.
Alldomain=" true " expression admin user can operate all MOC instances.
Test user then can only carry out " IP-BND-ACLLNK-PORT " order, and this user can only issue the TL1 order in the MOC example ranges of domain constraint simultaneously.The scope of MOC instance can be an independent network element, also can be a group NEs.
Set up semi-structured or the structural knowledge storehouse, TL1 northbound interface can carry out comprehensive reasoning decision-making through knowledge base according to the north orientation TL1 request of the NMS that receives, dynamically generates concrete CLI order and is issued to equipment.
Store following content in the knowledge base:
(1) TL1 orders the conversion relevant information of network element CLI order.
(2) mapping relations of network element version and concrete CLI order.
(3) TL1 orders the mapping relations of concrete service logic class.
Particularly, knowledge base establish dual mode, a kind of mode of database that is to use is set up the structural knowledge storehouse, another kind is to use the mode of configuration file to set up semi-structured knowledge base.
Be example with TL1 order " IP-TL1-ACLLINK-PORT " below, explain with the mode of configuration file and set up knowledge base:
Is the method for CLI order like said execution mode of Fig. 3 with the TL1 command conversion, comprising:
After 301:EMS received the TL1 command request of NMS, parsing obtained NMS and goes up the command parameter of device type, IP address of equipment, TL1 command name and the input of network element under current user's name, the EMS and the Hash mapping table (nameValueHashTable) of parameter value from this request;
302: the authentication entity in the northbound interface is resolved the control of authority file user and TL1 order is carried out authentication according to user's name, command name;
303: if authentication is passed through, then execution in step 304; Otherwise, execution in step 313;
304: authentication entity calls the syntactic analysis that the syntactic analysis entity carries out the TL1 order, and the syntactic analysis entity is according to the command format of this TL1 order in the knowledge base, to TL1 order the carrying out syntactic analysis that receives;
305: the syntactic analysis entity judges whether syntactic analysis is passed through, and asks the frequent degree analysis through execution in step 306 then; Otherwise, execution in step 313;
306: the adaptive entity of syntactic analysis entity invokes request, ask adaptive entity that the request frequent degree of TL1 order is analyzed, with the safety problem that prevents that unauthorized user malicious attack from bringing;
The TL1 request frequency threshold value of every order is stored in the knowledge base, and the maxfreg=10 that describes like above-mentioned configuration file representes that per minute surpasses 10 times TL1 command request, and the EMS refusal is further operated.
307: ask adaptive entity to judge whether the request frequent degree analysis of TL1 order is passed through, through execution in step 308 then; Otherwise, execution in step 313;
308: ask adaptive entity to identify, judge the concrete processing mode of TL1 order according to this TL1 process of commands mode that disposes in the knowledge base;
309: if adopt transparent transmission to handle, then execution in step 310; Otherwise, execution in step 312;
" useEMS " in the knowledge base is the processing mode sign of TL1 order " IP-TL1-ACLLINK-PORT "; UseEMS=" false " expression adopts transparent transmission to handle; The business logic processing class is read in useEMS=" true " expression from businessClassName path adopts the business logic processing class to handle.
310: ask adaptive entity that command mapping and assembling entity are entrusted in the TL1 order, command mapping is assembled into the CLI order with the assembling entity with the TL1 order;
The detailed step of order assembling is following:
Steps A 1: read the MOC and the version information of network element according to net element information (like the IP address), search TL1 in the mapping relations information according to MOC and the TL1 order of version information from knowledge base and CLI config set and order corresponding CLI config set;
The CLI config set is the value value collection that cliCommand is corresponding in the above-mentioned configuration file.The corresponding at least CLI config set that identifies with MOC information and version information of TL1 order in the mapping relations information of TL1 order and CLI config set.
Steps A 2: to the corresponding CLI config set of TL1 order, scan the value value (CLI order) of cliCommand from top to bottom, if the current CLI that scans contains configuration parameter (param) in ordering, execution in step A3 then; Otherwise, the value value of the current cliCommand that scans is added in the CLI command group to be issued;
Steps A 3: the parameter reference (being the value of the index among the cliCommand) that parses the configuration parameter in the steps A 2; The mapping relations of CLI parameter reference and TL1 command parameter are stored in the TL1-param node of knowledge base; The parameter value of the TL1 command parameter that parameter reference is corresponding can directly find through the nameValueHashTable table; The mapping relations information of preserving command parameter and parameter value in the nameValueHashTable table; With the parameter value replacement cliCommand De ${paramx} part of the TL1 command parameter that obtains, and the content after will replacing adds in the CLI command group to be issued;
Attention: in knowledge base, also comprise parameter value mapping relations information (< value-map >) for some TL1 orders; After in the nameValueHashTable table, finding the value of parameter title; If between < value-map>label, can find this parameter title, then need adopt the part of the corresponding emsMapValue replacement CLI command template of the value (mapping value of nmsValue) of this parameter.
After accomplishing, promptly accomplished the structure of CLI command group to the whole cliCommand scannings under a network element version and the MOC.
311: order issues entity the CLI command group is issued to corresponding net element, issue successfully after, carry out the record of Operation Log.
312: service processing entity reads the path of the business logic processing class among the businessClassName in the knowledge base, carries out concrete business logic processing class and handles;
313: make up the TL1 response message, return to upper layer NMS NMS.
Can also expand the TL1 knowledge base in this execution mode, realize knowledge-base management.
The TL1 knowledge base is stored in the server end of network management system.The expansion of TL1 knowledge base can use the graphic user interface of client to import; This makes the webmaster storehouse that dynamically expands knowledge that can be in operation; Therefore; This execution mode has stronger dynamic adaptable to the dynamic requests of NMS, comprises TL1 command name, command syntax format, TL1 parameter title, TL1 parameter type and TL1 parameter area etc.CLI order, CLI parameter and the mapping relations of TL1 parameter and the mapping relations of NMS parameter and EMS parameter.
Is one to one based on the organizational form of the knowledge base of database with organizational form based on the knowledge base of configuration file, and the organizational form concrete based on the knowledge base of database is following, can be divided into following four tables.
Table one: TL1 order base attribute table
Table two: TL1 parameter list
The mapping relations table of table three: MOC and version and CLI order
Table four: NMS and EMS parameter value mapping relations table
Below with IP-BND-ACLLNK-PORT order, be that the example explanation is the method for CLI order with the TL1 command conversion based on the knowledge base of database mode, comprising:
Step B1: resolve and obtain command name IP-BND-ACLLNK-PORT; Obtain MOC type and concrete network element version according to DIP (Device IP); The value of each TL1 parameter is respectively: IFNAME=gei_2/1; ACLID=200, DIRECTION=0 stores the mapping relations of parameter title and value in the Hash table (nameValueHashTable) into;
Step B2: according to MOC type and network element version; The corresponding CLI command template interface ${param1} of order IP-BND-ACLLNK-PORT in the scan table three; Index 1 look-up table two corresponding according to interface ${param1}; Obtain index 1 corresponding IFNAME (port title), from nameValueHashTable, search the value gei_2/1 replacement 1} of IFNAME, obtain CLI order interface gei_2/1 and add the CLI command group;
Similarly; Find the value 200 Ti Huandiao ${param2} of ACLID, find the value 0 of DIRECTION, convert in into through reading table 4 (NMS and EMS parameter value mapping relations table); Ti Huandiao ${param3} generates second command ip access-group 200in and joins the CLI command group;
Step B3: call instruction issues entity the order of CLI command group is issued to concrete network element.
It is following to obtain concrete command group through step B1 and B2:
interface?gei_2/1；
ip?access-group?200in。
