Description
Technical Field
The invention relates to an Operation and Maintenance Center (OMC) northbound interface data processing technology in the field of comprehensive resource management, in particular to an OMC northbound interface data processing method and device.
Background
The Northbound Interface (Northbound Interface) is an Interface for a manufacturer or an operator to access and manage a network, i.e., an Interface provided upward. Various application systems are developed by using interface programming in the network to manage the managed objects by collecting and analyzing various data generated by the managed objects in the running process. Management in a telecommunication Network and a Next Generation Network (NGN) is implemented hierarchically, and as shown in fig. 1, such Network management can be divided into three layers: the system comprises a data application layer, a data processing layer and a data acquisition layer. The data interaction between the data application layer and the data processing layer defines an interface, and the interface is called a northbound interface because the data application layer is positioned above the data processing layer.
The north interface file is generally an Extensible Markup Language (XML) file, and Java or Perl Java may be used to parse the XML file, where currently, the commonly used XML file parser mainly includes: XML Simple application Programming interface (SAX, Simple API for XML), Document Object Model (DOM, Document Object Model).
The advantages of SAX processing are very similar to those of streaming media. The analysis can start immediately instead of waiting for all data to be processed. Furthermore, since the application only checks the data when reading it, there is no need to store the data in memory, which is a great advantage for large documents.
DOM and generalized tree-based processing have several advantages. Since the tree is persistent in memory, it can be modified so that the application can make changes to the data and structure. It can also navigate up and down the tree at any time, rather than being a one-time process like SAX. The DOM is also much simpler to use. On the other hand, constructing such a tree in memory involves a large amount of overhead.
JDOM is intended to be a Java specific document model that simplifies interaction with XML and is faster than DOM implementations. JDOM has been greatly expanded and promoted by the first Java-specific model. DOM4J is an intelligent branch of JDOM that incorporates many functions beyond basic XML document representation, including integrated XPath support, XML, Schema support, and event-based processing for large documents or streamed documents.
Since Java operation has a limit to file size, Java processing is laborious for transmission files often exceeding several G. Files are commonly processed by Perl, which is relatively easy to migrate and develop.
The Perl parsing XML file is divided into packet parsing and pattern matching parsing.
Packet parsing: xml:: Parser. xml:: Parser series initial Perl Parser xml:: Parser:: Expat, written by LarryWall several years ago and kept running by ClarkCooper. The interface as ExpatXMLparser is written in the C language by james clark and has been adopted by some scripting languages. The Expat in Perl parsing XML file is event based, meaning that a specific condition triggers a processing function. For example, a start or end marker will trigger the appropriate user-defined subroutine. And (5) constructing a Parser module for common application on the basis of the function of the Expat. Note that Expat does not validate XML before parsing and fails when an error is encountered. These limitations make the XML Parser module very fast.
Pattern matching and analyzing: and performing pattern matching labeling by using a regular expression so as to obtain labels and values.
Theoretically, packet parsing is effective, but because the network manager has the manually input Chinese name, the Chinese name of the network element is messy due to manual operation. When encountering code messiness, the Expat fails, thereby causing failure in acquisition and resolution.
In the traditional analysis and summarization, each manufacturer independently updates and summarizes data association because of field difference. The prior art has the following defects:
analyzing the frequent interruption: because packet analysis is adopted, when network management has messy codes, network management manufacturers are many, data is not standard, and formats are difficult to unify, analysis is frequently interrupted, so that data storage and analysis cannot normally work.
Chinese disappears without cause: if Chinese characters or partial full-angle characters exist in the analysis, the characters disappear or cannot be processed without any reason in the prior art, and the data storage is also influenced.
The data value length is not sufficient: the use of the sequence generation ID makes the numerical length insufficient as resources are changed and the mobile network size is enlarged.
Associated resource refresh is slow: because of the need to convert various attributions into IDs, database resources, particularly relevance data, are consumed greatly, and processing time is extremely slow.
The summary takes too long: because a part of network management data tables are very large, for example, transmission time slots are not split, corresponding time slots can not be found frequently in the process of channel route serial communication. Leading to channel route collusion failures, which are time consuming to summarize.
In the prior art, due to the defects, the acquisition quality and the comparison condition of the comprehensive resource system are directly influenced, and the perception for maintainers and interface manufacturers is extremely poor. In the daily comprehensive resource management process, user perception is influenced to a certain degree, smoothness of a network access flow acquisition and comparison link and success rate of circuit scheduling channel communication are influenced due to interruption of data acquisition and analysis, a flow needs to wait for data acquisition, and the confidence of a user on a system is influenced due to overlong data gathering time. Influences the stability and timeliness of the external interface and influences the timeliness and accuracy of data acquisition, and becomes a great problem which puzzles resource management and data application.
