An example of virtual private networks
Source publication
ATM technology simplifies the application of logical connectivity and Virtual Private Network (VPN), which provide more flexibility for network management. This flexibility increases the complexity of management task, and requires special treatment. In this paper, we introduce a WWW-based three-dimensional user interface, in which managers can coll...

... this paper, we discuss a three-dimensional collaborative environment for distributed management of telecommunication networks. We focus on issues related to virtual private networks (VPNs) overlayed on an ATM core network ( Figure 1). The user interface is based on a World Wide Web (WWW) browser using both text (HTML) and 3D graphics (VRML). ...

... The COMET group has studied how virtual reality may be used within the context of ATM network management [2]. [3] and [4] presents a network management tool that supports collaborations between users and is accessible from a web browser. In parallel, researchers started to focus on visualizing the network data rather than to limit the visualization to the network structure and connectivity. ...
In this paper, we present experimental network management tools developed within the context of the CyberNet research project. The aim of this project is to study how metaphoric 3D visualization may help the user in the process of monitoring large amounts of dynamic information. Although the project focuses on a specific application domain, network management, it is designed so that it can be applied to other domains. The paper presents how 3D metaphoric worlds are automatically build from real world information dynamically collected on the network. It then focuses on several network administration tools that have been developed for helping network managers to track and understand problems. The paper also presents how 3D navigation and interaction are handled by the system in order to help the user in its task.
... To reduce the risk of human mistakes, we have been investigating the use of Virtual Reality (VR) user interface technology for network management applications. In particular, a WWW-based three-dimensional multiuser environment, called WNMS [6], has been developed for this purpose. ...
Network management is one of the important issues in current networks. As network management is a continuous task, which still relies on human for critical decisions, the effect of the user interface on network operators is important. In this paper, we compare the overal taskload of two types of user interfaces for network management. A typical commercial traditional 2D system, Cabeltron Spectrum, is compared with the prototype 3D WWW-based Network management System (WNMS). The NASA TaskLoad indeX (TLX), with a new WWW- based user interface, was used for comparison.
... In the first model (Kahani, 1995), we deployed an immersive virtual reality environment, consists of Head Mounted Display (HMD), pointing devices, joystick, and other input devices. The observation from the implementation of the system has led us to build a non-immersive, distributed, collaborative, 3D interface using WWW techniques (HTML, VRML, Java and JavaScript) (Kahani, 1996). In this paper, firstly, the special requirements of a distributed and collaborative network management system are discussed. ...
In this paper, we will introduce two different three dimensional VR-based user interface for telecommunication network management. The first one is an immersive system, using HMD and other 3D input devices. The other is a WWW-based flat screen 3D collaborative user interface. The architecture of each system and our observation from it will be described. Then, a comparison will be made to show the merits and pitfalls of each.
We discuss some of the issues in collaborative persistent virtual world design and implementation for geographically-dispersed users. The development of a protocol which suits these environments are discussed. We illustrate our discussion using a persistent 3D VRML-based multiuser virtual world built for the management of telecommunication networks.
Networks are becoming increasingly complex as a result of new technologies in hardware and software. Consequently, the traditional WIMP-based user interfaces are no longer suitable for management of large and high-speed broadband networks. In this paper we introduce two kinds of three-dimensional user interfaces: an immersive virtual reality user interface and a WWW-based flat screen 3D collaborative user interface. A comparison of the approaches is also made to show the merits and pitfalls of each.
