The Design And Realization Of Servcie Flow Monitoring System Based On The Dynamic Service Delivery Network

Web Service technology and SOA system as the latest progress of the IT field, and has a profound impact on the development of enterprise software.Web Service on the network number is also growing fast, in order to dynamically find and select the same or similar Web Service, we usually use QoS (Quality of Service QoS) as the evaluation and measurable criteria, and monitor real-time running condition of network Web Service, so that it can optimize the dynamic real-time selection of Web services. The main content is the research project of the National Natural Science Foundation of the key technologies of dynamic service resource distribution network and building a service-oriented stream monitoring system in the service resource dynamic distribution network (SDN).Traditional service monitoring system monitor the fixed QoS attributes, not flexibly and dynamically monitor the new QoS attributes and areas of non-functional QoS attributes. The associated QoS attributes reflect business content, in the field of application-specific business context and ISP information, and they are important reference factors for Web services to evaluate and select.In order to solve the dynamic monitoring service delivery network service-flow, Chapter2, deeply study the key technologies of Web Service application in monitoring system,the Quality of Server technology and Enterprise Service Bus technology。Meanwhile, in order to meet the needs of monitoring system on key parameters of service properties,in Chapter3,design the non-functional properties of Web services QoS extension model and attribute parameters calculating formula,also design service flow identification method by endpoint reference、service resource lifecycle、data flow and control flow. On the basis of the above study, Chapter IV of this paper the overall framework of the structure of the service-oriented flow monitoring system, to design a monitoring system on the level of the enterprise service bus architecture with policy-based monitoring model, special matter primarily for monitoring processes strategy and attribute computing strategy, monitoring system according to the logic function module divided, registration centers, polling, feedback and QoS monitoring system to calculate the four modules. Chapter detailed implementation of the monitoring system, through improved Nagios and Ganglia framework to build the monitoring system of the skeleton, followed by four modules, the monitoring system run with personalized queries and Web service flow QoS attributes monitoring implemented by system simulation testing laboratories to verify the functionality of the monitoring system. The final chapter summarizes the research work done in this article, the next stage of the research work made about Outlook.The main contribution of the paper is that the design of web service flow monitoring system model based on dynamic service delivery network, through Web services QoS attributes parameter and the corresponding QoS algorithm to calculate, dynamically monitoring runtime Web services and realize runtime Web service performance evaluation system, providing objective performance data to complete the dynamic performance of the real-time monitoring service delivery network system services distribution network in the migration, caching, selection, combination and optimization of Web services. And through service delivery network, Web services flow simulation, deployment and testing, to verify the functionality and dynamic performance of the monitoring system.
