摘要： 基于NetFlow流技术通过提取园区网边界数据流的地址、端口、协议和流量等特征属性在三维空间中建立流的几何可视化模型，简化了网络流量的显示，设计了基于地址段A的可变坐标几何建模算法，优化了模型的渲染，为网络管理人员提供了一种通过流的3D可视化图形来感知网络运行性能的手段。实验表明该模型有效反映了网络流量的相关特征。

Abstract: Based on the NetFlow technology, this paper submits a visible flow geometric model in space of three dimensions by using some characters of campus network’s boundary traffic. Those characters include IP, port, protocol and volume of flow. This model simplifies display of network’s traffic. An algorithm of A-based alterable coordinates modeling is designed to optimize model rendering. The model and algorithm provides a method for network manager to apperceive network performance by 3D visible graph of flow. Experiment shows that the model effectively reflects relevant characteristics of traffic.

Key words: network management, traffic, NetFlow technology, visualization, modeling
