(4) public service layer
Public service layer is mainly used in providing public service bottom and independent of service, comprise a plurality of public service assemblies, these public service assemblies offer the assembly of three levels above and use, for example, public service layer can comprise the public service assemblies such as log services assembly (Log Bundle), authorized component (License Bundle), south orientation communication part and monitor component (Monitor Bundle), south orientation communication part is used for and NEF system made physical connection, and monitor component is for passing through dynamically tracking message of probe.
Below in conjunction with Fig. 2, describe the principle of work of the embodiment of the present invention one in detail.
The OSF system queries alarm of take is example, first, Communication Layer processing module in north interface system call north orientation communication part set up with OSF system between be connected, receive the soap message for query warning that OSF system sends, adaptation layer processing module is called SOAP assembly the soap message for query warning is converted to data object, and data object is sent to the alarming processing assembly in operation layer, operation layer processing module is called alarming processing assembly and is converted data object to business realizing data, for example, business realizing data comprise alarm time of origin, alarm frequency, alarm originating port etc., alarming processing assembly sends to business realizing data the south orientation communication part of public service layer, public service layer processing module called south orientation communication part business realizing data sent to NEF system.
In embodiment as shown in Figure 1, adaptation layer processing module specifically can be carried out the conversion of protocol level for calling the first adapter assembly to the message receiving, and the format conversion of the message that receives is become can be by the form of Network Element Function collection NEF system identification; And the jar file generating according to business to be released is loaded under the path of dummy argument assembly appointment, start the Service Component that dummy argument assembly and business to be released generate, the Service Component of service creation to be released is registered to the first adapter assembly, finishing service issue.
Described dummy argument assembly is the necessary assembly of predefined described the first adapter assembly, and described dummy argument assembly can load any protocol data jar file from the path of a prior appointment.
Below in conjunction with Fig. 2, describe the process that adaptation layer processing module completes dynamic Service issue in detail.
Page Service descriptive language (Web Services Description Language, be called for short WSDL) be the basis of a Page Service of definition (Web Service), WSDL comprises two parts content: type (Types) and binding information (Binding), type definition is used the form of the data of the required exchange of this Page Service (Web Service), be the data layout in soap message, binding information is used for defining the mapping relations between the soap message that this Page Service (Web Service) accepts and the java method that finally realizes this service.
The instrument that first wsdl document will define by JAXWS compiles to generate the class that java is relevant, JAXWS is java application programming interface (the ApplicationProgramming Interface of XML Page Service (Web Service), be called for short API), because WSDL is language independent, and that concrete realization is language is relevant, so the process of compiling is exactly language binding process.The process that in this and CORBA, interactive data language (Interactive Data Language is called for short IDL) is compiled into appointed language is identical.Wsdl document after being compiled generates two major parts: business end interface (ServiceEndpoint Interface is called for short SEI) and protocol data class.Protocol data class is the compiling result to the type in WSDL from java-xml data binding (being called for short JAXB).SEI itself is a java interface, and the supplier of Page Service (Web Service) will realize this interface exactly.Protocol data class is called the needed java data type of this interface exactly.
The protocol data class that compiling wsdl document generates need to be packaged into independently jar file.
Owing to having used different Classloaders between assembly and assembly, so must use the mode importing and exporting to allow different assemblies realize sharing of class, this is the core concept of OSGI.Register a Page Service (Web Service), the SEI that just compiling wsdl document must be generated registers the assembly to SOAP, simultaneously need to see any necessary data message of service that is registered during SOAP assembly operating, compile the protocol data class that wsdl document generates.So SOAP assembly also must import the data message of different WS DL file generated.But the angle from engineering, what information SOAP assembly need to import is not to realize determining, need to determine according to concrete Page Service (Web Service), when therefore issuing new Page Service (Web Service) at every turn, all need to revise SOAP assembly and obtain MAINFEST.MF file, this just causes the framework of north interface system there is no independence.
In order to address this problem, in the embodiment of the present invention, define a dummy argument assembly (MetaDataBundle), this dummy argument assembly itself does not comprise any jar file, this dummy argument assembly can load any protocol data jar file from the path of a prior appointment, and all public interfaces are derived.Meanwhile, this dummy argument module sets is become to the necessary assembly (Required Bundle) of SOAP assembly, this just means that all derivation common datas of dummy argument assembly all import in SOAP assembly default.
Be illustrated in figure 3 dynamically distribution principle schematic diagram of Page Service in the embodiment of the present invention (Web Service), when having new Page Service (Web Service) to issue, jar file is loaded under dummy argument assembly path, then according to service creation Service Component to be released, this Service Component is for realizing new service to be released.Start Service Component and the dummy argument assembly of service creation to be released, the Service Component of service creation to be released obtains the enrollment page service (Web Service) of SOAP assembly issue, then by SEI to SOAP component register, the Service Component that is service creation to be released is registered to SOAP assembly, has so just completed the dynamic issue of a service.
In embodiment shown in Fig. 1, adaptation layer processing module can also be for stopping Service Component to be nullified, and the jar file generating according to business described to be nullified under the path of removal dummy argument assembly appointment, restarts dummy argument assembly, and finishing service is nullified.
Below in conjunction with Fig. 2, illustrate that adaptation layer processing module completes the process that service is nullified.
The process of nullifying service is just in time contrary with the process of issue.
First, adaptation layer processing module stops the Service Component of need nullifying, and then removes the jar file generating according to business to be nullified under the path of dummy argument assembly appointment, restarts dummy argument assembly, and finishing service is nullified.
In embodiment as shown in Figure 1, public service layer processing module can also be obtained for calling monitor component the collection result of each probe, and the collection result of each probe is pushed in a message queue, probe comprises for the probe of supervisory system resource, for obtaining the probe of the information of calling service and user-defined probe; Call monitor component, according to fetch strategy, from message queue, extract the collection result of probe.Adaptation layer processing module specifically can also be for sending to user browser by the collection result of probe by HTML (Hypertext Markup Language) (HTTP).
North interface system is different from the other system in network management system, and the other system in network management system is used identical technology and stable interface, and 99% problem has just solved when system is issued.But, north interface system need to dock different other systems, and other system has very large uncertainty, cannot test in advance other system, when breaking down, cannot determine at short notice it is that fault has appearred in north interface system or fault has appearred in other system.Trace it to its cause, mainly due to opaque the causing of existing north interface system internal state management.
In order to address this problem, in the embodiment of the present invention, public service layer processing module called the collection result that monitor component obtains each probe, thereby can follow the tracks of all message, state and resource in northbound interface, obtains the state parameter of each message in north interface system.
