摘要 随着云计算、大数据以及物联网的兴起,网络流量以爆炸性的速度增长,与此同时网络带宽的增长速度却无法与之相应匹配。在可预见的将来,日益增长的网络流量与缓慢增长的网络带宽之间的矛盾将长期存在。如何改变当前粗放式的网络管理手段,实现精细化的网络管理,解决上述矛盾是需要面对的问题。提出基于状态的视图模型,描述了全局状态视图的形式化概念,同时详细介绍了全局状态视图的构建算法,并拓展其外延,提出状态视图栈的概念,扩充定义网络各层状态视图。利用层次Petri网对传输层协议建模并分析其特征,构建其状态管理表。分析了端口碰撞应用,并构建该应用的状态视图,说明了状态视图栈的一般性扩充方法。同时以负载均衡功能结合全局状态视图应用为例,说明基于状态的网络管理可以提高资源的利用率。

英文摘要 With the rise of cloud computing, big data and the Internet of Things, network traffic grows at an explosive rate, while the growth rate of network bandwidth cannot match it. In the foreseeable future, the contradiction between increasing network traffic and slow growing network bandwidth will exist for a long time. How to change the current extensive network management means, achieve refined network management, and solve the above problems is the question need to face. This paper presented a state-based view model, described the formal concept of the global state view, and also expanded the extension of the concept of global state view, proposed the concept of state view stack, and expanded the state view of each layer of the defined network. It used the hierarchical Petri net to model and analyze its features, and introduced the global state view construction algorithm in detail. It analyzed the port collision application and constructed the state view of the application. At the same time, this paper took load balancing function plus global state view application as an example to illustrate state-based network management could improve resource utilization.
