【摘要】：伴随着计算机网络近些年的持续进步和发展,各种不同类型的计算机网络相关用户的网络需求在不断变化,众多计算机网络用户则希望应用计算机网络进行信息传输的相关信息的种类也玲琅满目,各种计算机网络用户对于网络提供的各种服务的网络服务质量的要求也在逐步提高,现有的传统类型网络的弱点和弊端不断突显,传统类型网络限制了新型网络的发展方向和新类型,新型的主动网络是解决传统类型网络中已经存在的诸多问题提供解决的方向和机遇。新型的主动网络包括可编程网络节点的新型结构,它可以为网络协议与网络开发新型服务、提供网络验证和网络系统部署等相关技术支持,也为网络控制管理、服务质量控制、可靠多播传输提供了崭新的方法。随着计算机网络和网络中相关应用的不断持续地发展,过往传统的数据报文交换类型的网络已经难以进行扩展,尤其是几乎完全不变的网络运行机制是制约数据交换类型网络进行发展的重要障碍。数据报文交换网络中的诸多中间点(比如各级路由器Routers、各级交换机Switchs)具有相对过去较强的运算能力(评价运算能力依据网络整体进行数据报文“存储——转发”过程的实际传输时间与路由过程时延进行计算),但数据报文交换的本质是被动地进行数据传输;另外,传统类型网络的更新成本高昂、操作周期较长,这些情况使得网络新型协议和新型服务很难在较短时间内进行快速实施部署,这些现状严重影响了计算机网络上各种新应用的快速推广和普及。本文通过对主动网络理论的深入研究,同时阐明主动网络的体系结构、主动网络分类、主动网络的ANEP封装协议、主动网络性能和各种主动网络系统,然后针对服务质量分析控制系统需求分析、总体设计、系统设计进行描述,最后说明系统开发平台、J-Sim仿真环境和模块设计及结果分析。本文研究在主动网络基础上探讨了主动网络中安全服务质量控制体系的结构,最后通过使用相关网络设计工具进行主动网络的服务质量分析控制系统执行功能实现。
[Abstract]:With the continuous progress and development of computer network in recent years, the network needs of various types of computer network related users are constantly changing. On the other hand, many computer network users hope to use computer network for information transmission, and the requirements of various computer network users for the network service quality of the various services provided by the network are also gradually raised. The weaknesses and drawbacks of the existing traditional type networks are constantly highlighted. The traditional types of networks limit the development direction and new types of new networks. The new active network is the direction and opportunity to solve many problems existing in the traditional network. The new active network includes a new structure of programmable network nodes, which can develop new services for network protocols and networks. It also provides new methods for network control management, quality of service control, reliable multicast transmission and so on. With the continuous development of computer network and related applications in network, In the past, the traditional data message exchange network has been difficult to expand. In particular, the almost invariable network operation mechanism is an important obstacle to the development of data-switched networks. Many intermediate points in data packet switching networks (such as routers at all levels, switches at all levels) have phase. This paper calculates the actual transmission time and the delay of the routing process of the data packet "storage-forward" process based on the evaluation operation ability, but the essence of the data message exchange is passive. Ground data transmission; In addition, the high cost and long operation cycle of the traditional type of network makes it difficult for new protocols and services to be deployed rapidly in a short time. These situations have seriously affected the rapid popularization and popularization of various new applications in computer networks. This paper studies the theory of active networks, and expounds the architecture of active networks and the classification of active networks. The ANEP encapsulation protocol of the active network, the performance of the active network and all kinds of active network systems are described, and then the requirement analysis, the overall design and the system design of the QoS analysis and control system are described. Finally, the simulation environment and module design of the system development platform, J-Sim, and the analysis of the results are described. Based on the active network, the structure of the security quality of service control system in the active network is discussed in this paper. Finally, the implementation function of the QoS analysis and control system of the active network is realized by using the related network design tools.
