【摘要】：进入信息时代,网络架构的不断发展及用户要求的日益提高为网络的管理带来了新的挑战。一方面,保证端到端的网络性能成为管理的核心。随着下一代网络的演进,各种应用层出不穷,实时业务(如VoIP,电话会议,多媒体远程教学和视频点播等)相继出现,这使得保证端对端的服务质量成为下一代网络管理的关键。另一方面,支持面向业务的特征成为网络管理的发展趋势。由于网络设备的正常工作并不能保证业务的正常运行,而用户更关心业务的质量,这使得以设备为关注对象的传统网管已不能满足网络发展的需求。另外,网络及业务的最终目的是为了保证通信以满足用户的需求,从而获取更大效益。而这些都要求了面向业务对网络性能进行管理成为必然。本文基于下一代网络架构,以网络中运行的业务为管理核心,提出了一个面向业务的网络性能管理架构。该架构从业务、服务及网络三个层面对网络进行监控,从而实现综合性能研究,其主要创新点包括:1.制定了高层告警定义的机制。实时监测业务的运行,并收集用户感知信息,通过神经网络系统建立客户满意度到业务指标之间的映射关系模型,从而分析在不同业务性能下,业务指标对客户满意度的影响权重。根据这些权重及具体的业务运行状况,我们制定一套定义高层告警的机制。2.提出了面向业务的网络性能管理架构。在定义高层告警的基础上,结合背景项目中的模糊关联规则挖掘模块及下一代网络管理机制,提出面向业务的网络性能管理架构。该架构建立起端对端的网络性能与高层指标的联系,实现从业务角度对网络性能进行管理。3.建立了一个在线的视频服务系统来验证方案的可行性。基于SOA架构,我们建立了一个分布式服务系统。校园网用户可以接入服务,进行查询、下载及欣赏音乐或视频,并随时为服务打分。业务指标及网络性能参数通过总线服务传送到服务器上,从而我们可以对这些数据进行分析并验证我们的管理系统。
[Abstract]:In the information age, the continuous development of the network architecture and the increasing requirements of users have brought new challenges to the management of the network. With the evolution of the next generation network, various applications emerge in end-to-end, real-time services (such as VoIP, teleconferencing). Multimedia distance learning and video-on-demand (VOD) have emerged, which makes end-to-end quality of service become the key of the next generation network management. Supporting business-oriented features has become the trend of network management. Because the normal operation of network equipment can not guarantee the normal operation of the business, users are more concerned about the quality of the service. This makes the traditional network management which takes the equipment as the object of concern can not meet the needs of the network development. In addition, the ultimate purpose of the network and business is to ensure communication to meet the needs of users. In order to achieve greater benefits, and these requirements for business-oriented network performance management become inevitable. This paper based on the next generation network architecture, with the network running business as the management core. This paper presents a service-oriented network performance management architecture, which monitors the network from three aspects: service, service and network, so as to achieve comprehensive performance research. The main innovation points include: 1. The mechanism of defining high-level alarm, real-time monitoring the operation of business, and collecting user perception information. The mapping relationship model between customer satisfaction and business index is established through neural network system, and then it is analyzed under different business performance. The impact of business indicators on customer satisfaction. According to these weights and specific business performance. We develop a set of mechanisms to define high-level alarm. 2. A service-oriented network performance management architecture is proposed, which is based on the definition of high-level alarm. Combined with the fuzzy association rule mining module and the next generation network management mechanism in the background project, a business-oriented network performance management architecture is proposed, which establishes the relationship between the end-to-end network performance and the high-level indicators. The implementation of network performance management from the business point of view. 3. Established an online video service system to verify the feasibility of the scheme. Based on the SOA architecture. We have set up a distributed service system. Campus network users can access services, query, download and enjoy music or video. Business metrics and network performance parameters are transmitted to the server through the bus service, so that we can analyze these data and verify our management system.
