DUALQUEST: An Implementation of the Real-time Bifocal Visualization for Network Management
Shoichiro Nakai, H. Fuji, Hiroshi Matoba · 1995
Most of the current network management systems employ graphic-user-interfaces for the network visualization purposes. These are well suited for both small- and medium-size networks. For a large-size network, hierarchical multi-window-based network visualizations are usually used; however, tracing a long path (i.e., composed of a huge number of nodes) may meet some difficulties because it must be at first divided into several segments displayed segment-by-segment in several windows. In addition, window manipulations, such as opening and closing operations, are quite complex. To overcome the disadvantages of the multi-window network visualization, we proposed a real-time bifocal network visualization that is capable of displaying both the context and all details of a network within a single window (Fuji, 1994). This paper enhances that approach and describes an implementation, called DUALQUEST, that was installed in a workstation equipped with a frame buffer memory proposed in (Matoba, 1990) for real-time bifocal image processing.
