Abstract
The invention discloses a test method for WS-BPEL workflow induction QoS analysis. The test method includes the steps that a central node is set, test programs request serial numbers from the central node, and the central code allocates the corresponding serial number to each test program and carries out heartbeat detection on the corresponding test programs entering a test environment; a user launches a newly-set test to the central node and sends test instructions to the corresponding test programs through the central node to carry out testing on target web services, testing results are fed back to the central node after testing of the corresponding test programs is completed, the central node displays the testing results to the user, and a service calling quality diagram is formed. The testing programs can log in to the central node automatically, a certain group of Web services is tested in a parallel or serial mode through the test programs, induction QoS parameters can be obtained, and therefore performance bottlenecks in workflow can be found more accurately.
Description
Technical field
The present invention relates to inter-network data passage analysis field, relate in particular to the method for testing of a kind of WS-BPEL workflow analysis perception QoS.
Background technology
Service quality (quality of service, be called for short QoS) be network with user between and between the user that communicate by letter mutually on network about the agreement of communication and shared quality, for example, transmission delay permission time, throughput, stability etc.On the computer networks such as Internet, for providing high-quality QoS, user must solve following problem: QoS is classified and defined, object is that network can be managed according to dissimilar QoS and Resources allocation, such as distributing larger bandwidth and more CPU processing time etc. to real time service.On the other hand, QoS being carried out to class definition also facilitates user to propose QoS demand according to different application.And for satisfied QoS is provided to user, must peer-to-peer system, the corresponding resource such as router and transmission bandwidth preengages, to guarantee that these resources are not used by force by other application.At present, in the relevant project development of Web service, extensively adopt WS-BPEL (full name is that Business Process Execution Language is business processing effective language) to set up robotization operation flow, but prior art can not accurate description flow process in data constraint or time-constrain between web services assembly, cause the bottleneck of workflow analysis.
Therefore, prior art needs further improve and develop.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide the method for testing of a kind of WS-BPEL workflow analysis perception QoS, to describe more accurately immediate data constraint or the time-constrain between assembly, the performance bottleneck that can find a job more accurately in stream.
Technical scheme of the present invention is as follows:
A method of testing of WS-BPEL workflow analysis perception QoS, it comprises the following steps:
A, set up Centroid, test procedure is to described Centroid request serial number, and described Centroid distributes corresponding sequence number to each test procedure, and carries out heartbeat detection to entering the corresponding test procedure of test environment;
B, user initiate newly-built test setting to described Centroid, and to corresponding test procedure, send test instruction by described Centroid, to objective network, service is tested, corresponding test procedure is completed backward described Centroid and returns to test result, described Centroid shows test results to user, forms service call quality chart.
Described method of testing, wherein, what described steps A was concrete comprises: described Centroid judges that according to heart time whether corresponding test procedure is online.
Described method of testing, wherein, what described steps A was concrete also comprises: corresponding test procedure sends a heartbeat packet to described Centroid in every 15 seconds, and described Centroid was not received the heartbeat packet of corresponding test procedure in 30 seconds, and described Centroid judges that corresponding test procedure rolls off the production line.
Described method of testing, wherein, what the test of described step B was concrete comprises: described Centroid records the initial data of each input service stream, and the web services that test procedure is provided, and each web services is classified as to one group; Record between the variable of each initial data process in workflow script and transmit between assignment and service, the web services of process and provider's web services of these data be designated as one group; Determine between the web services of same group and there is data constraint relation and time-constrain relation, submit to described Centroid to test whole perceiving service quality the web services of each grouping.
Described method of testing, wherein, what described step B was concrete also comprises: by traceroute, determine that IP packet accesses the path that web services to be measured is taked.
Described method of testing, wherein, what described step B was concrete also comprises: when testing data bag access time summation is less than or equal to 1 second, skip traceroute; When testing data bag access time summation is greater than 1 second, carry out traceroute.
The invention provides the method for testing of a kind of WS-BPEL workflow analysis perception QoS, defined a kind of new data structuring model that is used for describing Web service constraints relation in workflow, be service call figure, adopt this model to analyze to produce between which assembly in same workflow (be Web service) and directly call or exchanges data indirectly, data constraint and time-constrain between assembly are described more accurately, for the analysis of perception QoS, the performance bottleneck that can find a job more accurately in stream; And carry out perception QoS test based on cluster test procedure, it provides a Centroid based on Web method of service, user is mutual so that the workflow of predefine WS-BPEL is tested with it, its test can be deployed in the different network segments and region, from trend Centroid, register, a plurality of tests walk abreast or a certain group of Web Service tested in serial, obtain perception qos parameter, the performance bottleneck that can find a job more accurately in stream.

Embodiment
The invention provides the method for testing of a kind of WS-BPEL workflow analysis perception QoS, for making object of the present invention, technical scheme and effect clearer, clear and definite, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
For following, describe conveniently, each English abbreviation is simply introduced.
Web service be a platform independently, loose coupling, self-contained, the application program based on programmable web, can describe, issue, find, coordinate and configure these application programs by open XML standard, for developing the application program of distributed interoperability.
WS-BPEL: full name is that Business Process Execution Language is business processing effective language, is the programming language that a kind of XML of use writes.For robotization operation flow, be also once known as WSBPEL and BPEL4WS.Be widely used in the project development that Web service is relevant, advantage is for having portability and effectively having protected investment.
Perception QoS:QoS(Quality of Service), be a kind of security mechanism of network, in order to weigh the quality of a certain network service, as response time, throughput, stability etc.Perception QoS directly reflects quality impression when user accesses certain Web service, conventionally by one group of index (as concurrent in network delay, services request, IT infrastructure etc.), reflect the service effectiveness that user awareness arrives, can pass through the active monitoring to these indexs, Services Composition is chosen, improved.
Service call figure: be used for a kind of model that BPEL workflow is analyzed, be used for analyzing between which assembly in same workflow (Web Service) producing and directly call or exchanges data indirectly, and then describe and between which assembly, there is direct data constraint or time-constrain.Can be used for carrying out data access authorization analysis and perception QoS analyzes
