Description
Technical field
The present invention relates to technical field in the computer network management, particularly a kind of method for monitoring service quality and system thereof based on service-level agreement.
Background technology
Along with networks development, more and more by the service that network provides, the Internet Service Provider need be according to user's actual needs provide services on the Internet function and quality, therefore requires monitoring network service quality all extremely important concerning user and Internet Service Provider according to the user.
Traditional network management management to as if equipment, the object of monitoring also is the network equipment, obtains the performance of network equipments parameter among the agency of slave unit.Therefore along with the increasing of network service, need the performance of monitoring network service, i.e. network service quality.The network service quality monitoring mainly comprises three parts:
1) service management agent, its record network service operation state information is called as initial data, and the original data record user uses information.The service difference causes administration agent interface difference, and the initial data of administration agent record also has nothing in common with each other.
2) data are obtained and the course of processing, and this process comprises raw data acquisition and computational process.According to the actual mass demand of different user, obtaining corresponding initial data from the agency is the raw data acquisition process, and requirement is calculated initial data and is called as computational process according to user quality;
3) service quality assessment compares the QoS parameter result that calculates and user's requirement, and handles accordingly according to the result, and this is called as evaluation process.
The network service provides according to being the service-level agreement that user and service provider sign, and therefore network service quality is monitored and must be used the situation of service according to the service-level agreement monitor user ' according to service-level agreement.And different user has nothing in common with each other to the requirement of service quality, therefore causes the demand of services quality monitoring system to have nothing in common with each other, and makes the network service quality observation process have many uncertainties.In three parts of services quality monitoring, uncertain being mainly reflected in: 1, the data of service management agent record have nothing in common with each other, and the management interface of the different service management agent that the service provider provided may have nothing in common with each other; 2, processing computational process in the service observation process has nothing in common with each other, the calculative mass parameter difference of different services, and same services is because the user's request difference, the service-level agreement difference of being signed, cause different user to the quality of service requirement difference, flow when providing such as some customer requirements network service, and calculate once per 5 seconds, and some customer requirements network service reaction speed is fast, therefore want calculating reacting time, and calculated once in average per 30 seconds, this also has nothing in common with each other with regard to causing service data corresponding in the observation process to be obtained with computational process; 3, the processing of carrying out after the service valuation has nothing in common with each other, and the customer requirements that has is compensated when service quality can not meet the requirements of, and the requirement that has record error message or the like.
These uncertainties are brought the unsteadiness of services quality monitoring system, when new service provides, need new monitoring system or need to revise original system, have caused the waste of resource, have prolonged the time that new service provides; In case monitoring system is finished simultaneously, the computational process in the observation process can not be changed arbitrarily, and limited subscriber is to the requirement of service quality.
In this case, need a kind of network service monitoring method to carry out quality-monitoring to the network service according to network service and user's demand, and the basis of this monitoring method service-level agreement that to be user and service provider sign embodies the requirement of user to service quality in the agreement.
Summary of the invention
The object of the present invention is to provide a kind of method for monitoring network service quality, make network service monitoring have adaptivity, satisfy the monitoring needs of different services, different user and different quality requirement.
Network service monitoring method based on service-level agreement.The present invention serves the monitoring system structure by a kind of service-level agreement describing method and network that embodies the network service quality observation process of design voluntarily, each function in the whole network service observation process is divided into various monitoring function services, simultaneously service-level agreement analysis is obtained the flow process of network service monitoring, and according to the flow process of analyzing gained various monitoring function service groups are lumped together, realize monitoring as required to the various network services quality.Characteristics of the present invention be the to improve service quality adaptivity and the flexibility of monitoring system, make the services quality monitoring system to carry out personalized monitoring, and need not develop the flow process of a cover monitoring system or stationary monitoring system again for the demand of new monitoring according to heterogeneous networks service, different customer requirements.When new monitoring requirements, monitoring method of the present invention only need be done little change just can adapt to new monitoring requirements.
The main process of services quality monitoring is to obtain certain user-dependent mass parameter from service monitoring agency, and the data of obtaining are calculated according to the statistical method of customer requirements, and the quality assurance of the result of calculation of gained and user's requirement compared, whether the evaluation services quality satisfies customer requirements, and carry out other according to actual conditions and handle, give and discount when for example when quality can not satisfy customer requirements, carrying out service quality adjustment or record violation or charging.Therefore in order to realize the automation of services quality monitoring flow process, solve service management agent in the services quality monitoring, data are obtained and process the uncertainty that exists in calculating, three parts of service quality assessment, the services quality monitoring process is divided according to this three part, with the various functions in the various piece as service, by the service combine engine, these service groups are lumped together, realize dynamic combined, self adaptation adjustment monitoring flow process.
In service was integrated, each functional module all was service, was undertaken integrated by unified interface description and call method.Therefore for the service management agent of various services, to adopt the WebServices technology to realize, the interface of service management agent adopts web services definition language (WebService Definition Language, WSDL) define, and (Simple Object Access Protocol SOAP) conducts interviews to the service management agent interface to adopt Simple Object Access Protocol.Also adopt Web Services technology to realize for the various functions that are used for calculating, the same WSDL that adopts describes interface, adopt SOAP to call, simple calculation services comprises addition subtraction multiplication and division computing service, binary arithmetic operation service, comparison operation service, series of operations service and some algorithm service or the like, by these calculation services being made up can operating various data.For the processing after the assessment, also will adopt Web Services technology to realize, various evaluation process then as service, in the time of needs, are called these services by soap protocol.Therefore related various network services administration agent, data computation function and processing capacity all is implemented as various services in the whole services quality monitoring process.On the basis that possesses these services, these services are realized monitoring to service quality according to certain logical combination together by the service integrating engine.
Service quality must be monitored according to user's demand, require the needed qualitative data of monitor user ' according to the user, requirement according to the user is calculated, and when not reaching the user and will go, quality carries out various forms of processing according to user's requirement, and service-level agreement provides the agreement that comprises user's request, various quality requirement and computational methods, various processing that the merchant consults to sign with the user, therefore the foundation of services quality monitoring be service-level agreement (Service LevelAgreement, SLA).So for the services quality monitoring system, the service monitoring logic of service integrating engine institute foundation must come from service-level agreement.
WSLA (Web Service Level Agreement) is the network classes of service protocol specification that is proposed by IBM Corporation, it has described the user to will the going of service quality, the computational process of quality of service data, the processing of service guarantees, it adopts the XML language to be described simultaneously, makes things convenient for analyzing and processing.
Therefore in the services quality monitoring system, adopt the description standard of WSLA as service-level agreement, the service integrating engine is called SLA and carries out engine, it is actually analyzing with the defined SLA of WSLA standard, therefrom obtain actuating logic, and call various services in the services quality monitoring system according to actuating logic.
It is as follows that SLA carries out the parser that comprises in the engine:
1, reads whole SLA, therefrom extract title, provider and the user of SLA;
2, a behavior of obtaining among the SLA guarantees (being defined as Action Guarantee in SLA), comprises that behavior guarantees the condition that corresponding grade of service target (being defined as Service LevelObject in SLA), processing behavior (being defined as Qualified Action in SLA) and processing behavior trigger;
3, the grade of service target of obtaining in the behavior assurance is analyzed, obtained pairing service operations of behavior grade target (in SLA, being defined as Operations) and QoS parameter;
4, analyze the computational process of this QoS parameter, computational process is described with data-structure tree, be called as the process tree, each node comprises title, computational methods and result, and wherein working as data is to define among the SLA, then directly as a result of, and there are not computational methods, if calculate by computational methods, then comprise computational methods, the result obtains in the process of implementation;
If 5 these QoS parameters are last QoS parameters in last this grade of service target, then carry out 6, otherwise return 4, analyze the related next QoS parameter in this grade of service target;
If 6 these grade of service targets are last grade of service targets in the current behavior assurance, then enter 7, otherwise return 3, the next grade of service target during current behavior is guaranteed is analyzed;
If 7 current behaviors guarantee it is that last behavior guarantees to enter 8 among the SLA, otherwise return 2, obtain next behavior and guarantee, analyze;
8, analytic process finishes.
SLA carry out engine to all QoS parameters according to the tree of being set up, execution from bottom to top, just calculate according to left and right sides data of tree and the computational methods in the intermediate node, result of calculation is upwards transmitted, and calculates once more as the operand of upper layer node.
For whole system, observation process is divided into multiple service, and therefore service register center of needs is come the various services in the Accreditation System, and the locating function of service is provided, when SLA carries out engine and do not know that the service that needs there, search by service register center.
The invention has the advantages that its architecture and, have very big flexibility, support the monitoring of the various ways of multiple service, adapt to user's different demands based on the monitoring of service-level agreement.Need monitoring as new service, only register the agency of this service, and in service-level agreement, specify this agency in service register center; If new computational process is arranged, also be to register this computational methods, and in service-level agreement, specify this method in service register center; If equally new evaluation process method is arranged, also only be that this processing method is distributed on service register center as service, and in service-level agreement, specify this processing method.The change of service monitoring requirements is smaller to monitoring system influence itself, and the overall structure loose couplings has very strong self-adaptation type.
A kind of method for monitoring network service quality, it is characterized in that, from service monitoring agency, obtain certain user-dependent mass parameter, and the data of obtaining are calculated according to the statistical method of customer requirements, and the quality assurance of the result of calculation of gained and user's requirement compared, whether the evaluation services quality satisfies customer requirements, and handles according to actual conditions.For example for video-on-demand service, customer requirements was gathered once every 5 seconds, calculated the once flow of average each second every 30 seconds, and require the per second flow greater than 1,000,000, when compensating by the reduction expense less than 1,000,000 the time, then serve monitoring system and need from the service broker, obtain the data of present speed every 5 seconds, and to preserve 6 be one group, calculate the mean value of 6 data then, the size that compares mean value and 1,000,000 then, when not satisfying customer requirements, call far management system and carry out the expense compensation.And different users is to the quality of service requirement difference, for example same video-on-demand service, different user requires need not, some user wishes to calculate average speed by calculating total flow and time, and requiring speed to be not less than 0.5 million, this just causes image data and data is calculated different with process meeting relatively.Therefore in order to realize the automation of services quality monitoring flow process, solve service management agent in the services quality monitoring, data are obtained and process the uncertainty that exists in calculating, three parts of service quality assessment, the services quality monitoring process is divided according to this three part, with the various functions in the various piece as service, by the service combine engine, these service groups are lumped together, realize dynamic combined, self adaptation adjustment monitoring flow process.For various services quality monitoring agencies, it is designed to the network service, use WSDL to describe interface, adopt the unified interface accessing form of SOAP, processing is calculated for data, the statistics and analysis comparative approach that promptly refers to the data that collect, generally comprise addition subtraction multiplication and division, array manipulation, series of operations or the like, with various function calculation method as various functional services, and the violation that adds customer requirements is handled also as various services, in fact be exactly that services quality monitoring is acted on behalf of then to the services quality monitoring process, obtain data, services, the data computation service and the service of handling are in violation of rules and regulations combined according to user's requirement, when customer requirements not simultaneously, the quality-monitoring agency who needs, the data computation service is with the processing service is different in violation of rules and regulations, but the different quality-monitoring processes that require of different user all are combined to form by these function services.
Described method for monitoring network service quality, mainly achieve the goal by network service quality monitoring system architecture, the method that we propose is based on service-level agreement, be applicable to the monitoring of various network services different quality requirement, can use the situation of service to monitor to the user that difference service, different quality require by this method, its concrete steps be as follows:
