卫星时变拓扑网络多视图可视化分析框架

深入研究卫星时变拓扑网络与信息可视化相结合的可视化分析问题，提出一个多视图可视化分析框架。该框架在集成传统两视图的基础上，重点关注卫星网络的动态时变特性，设计实现一个新颖的时变拓扑网络可视化视图，该视图遵循网络布局的美学标准，并且维护用户感知网络拓扑的意象图。实验验证表明，多视图可视化分析框架丰富了卫星网络可视化的表现形式，多角度展示了卫星网络的时变特征，能够支撑数据包路由分析等应用，辅助用户感知网络并做出合理决策。

Multiple view framework of visual analytics for time varying satellite topology network

The visual analytics problem is deeply studied which combines the time varying satellite topology network and information visualization, and a multiple view visual analytics framework is proposed. This framework integrates traditional two view structure, focuses on the dynamic time varying characteristic of satellite network, designs and implements a novel time varying topology network visualization view which obeys the aesthetic standards of network layout and preserves the user's mental map for network topology perception. The experiments show that the multiple view visual analytics framework enriches the patterns of satellite network visualization, represents the time varying characteristic from multiple perspectives, and has the ability to support the applications such as routing analysis of data packets, and assists the users to understand network and make decision.
