【摘要】：随着互联网技术的普及和应用，在网络通信服务行业中，网络业务的服务质量逐渐成为了人们关注的重点。但是互联网中的资源并不能满足所有的需求，只要资源被多个应用请求，就需要保证网络应用的服务质量。但在确保某一类网络业务服务质量的时候，可能同时在破坏其它网络业务的服务质量。例如，，在大型网络应用中，有大量业务需要排队处理，就不得不对特定的重要业务予以优先权，并分配更多的带宽。所以，网络管理员必须依据业务的实际情况对网络资源做正确的规划和分配，从而更有效地使用网络资源以保证网络业务的服务质量。为了解决网络中各种业务的服务质量管理问题，按照软件工程方法，通过对系统需求进行了深入的分析，将整个系统分为QoS设备管理、QoS资源管理、部署任务管理和业务部署管理四大模块，并分别给出系统用例图。按照QoS管理的特点，开创性的将QoS资源分为流分类、流行为和流策略三种，为QoS任务的部署下发提供了一个简单可靠的解决方案。对系统进行总体的设计，依托某大型网络服务管理系统，采用B/S结构，使用当今业界流行的三层架构和J2EE框架，并在此架构基础上，整合了很多开源中间件，极大的简化了开发流程。对四大功能模块分别进行功能设计，并给出了相应的流程图。采用HighChart技术，使系统能够提供动态的审计报表，进一步提升了系统的性能。所实现的网络质量服务系统，支持设备配置同步和审计，支持任务部署。当网络发生过载或拥塞的情况时，能确保重要业务不受影响。使网络资源得到充分利用，保障了网络的高效运作。
[Abstract]:With the popularization and application of Internet technology, the service quality of network service has gradually become the focus of attention in the network communication service industry.However, the resources in the Internet can not meet all the requirements. As long as the resources are requested by multiple applications, the quality of service of the network applications should be guaranteed.However, in order to ensure the quality of service of certain network services, it may destroy the quality of service of other network services at the same time.For example, in large network applications, a large number of services need to be queued up, so they have to give priority to certain important services and allocate more bandwidth.Therefore, network administrators must make correct planning and allocation of network resources according to the actual situation of business, so as to use network resources more effectively to ensure the quality of service of network services.In order to solve the problem of QoS management of various services in the network, according to the software engineering method, the system requirement is deeply analyzed, and the whole system is divided into QoS equipment management and QoS resource management.Deployment task management and business deployment management are four modules, and system use case diagrams are given.According to the characteristics of QoS management, the QoS resources are divided into stream classification, popular and stream strategy, which provides a simple and reliable solution for the deployment of QoS tasks.The overall design of the system, relying on a large network service management system, using the B / S structure, using the current industry popular three-tier architecture and J2EE framework, and on the basis of this architecture, integrated a lot of open source middleware,Greatly simplifies the development process.The four functional modules are designed, and the corresponding flow chart is given.Using HighChart technology, the system can provide dynamic audit reports, and further improve the performance of the system.The network quality service system supports synchronization and audit of equipment configuration and task deployment.When the network is overloaded or congested, it can ensure that important business is not affected.Make full use of the network resources, and ensure the efficient operation of the network.
