I n recent years, the Internet has seen an increase in the number of new applications that rely on multicast transmission. Multicast is a technology that conserves bandwidth in point-to-multipoint transmission. With the development of Mbone technology, an Internet-wide virtual network for point-to-multipoint transmission, group communication becomes possible NetMeeting, NetShow and many other a...

service, firewalls need more than static packet filtering and application-level proxies. SOCKS is an application-independent transport-level proxy that offers user-level authentication and data encryption. An extended SOCKS UDP binding model with appropriate socket calls is proposed to provide complete support for UDP-based, multimedia streaming applications. T he increasing popularity of multi...

1 The CASTLE project (Computer Aided System for Tele-Interactive Learning in Environmental Monitoring) was funded under the EU Programme “Environment and Climate”, DG XII, No. ENV4 CT96 0312 from August 1997 to July 1999. Members of the project consortium were: Christian-Albrecht University Kiel (D), C.I.C.E.M. Huelva (E), University of Dundee (UK), Deutsches Zentrum für Luftund Raumfahrt (D), ...

The Internet has changed the face of computing. The use of e-mail and desk-top video-conferencing has made collaboration between people very easy and very natural. Application-sharing technology, such as provided by Microsoft's NetMeeting, allows a single application to be accessed by a group of people at different locations. The Internet likewise enables collaboration between computers-the Dis...

The main objective of the Magic WAND (Wireless ATM Network Demonstrator) project was to develop a wireless ATM demonstrator system and evaluate it in real-life user environment. The output of the project comprised a Wireless ATM Access Network Demonstration system. The developed applications and the WAND hardware was evaluated in different user trials. In this paper we focus on the main results...

We present a hardware/software system for support of distributed Extreme Programming, or DXP. It consists of a dual video projector setup with NetMeeting running on a single PC, and a hypervideo system we built called OvalTine. OvalTine allows the creation and automatic tracking of hyperlinks in a video stream, both archived and real-time (as in video conferencing). DXP supports the development...

They missed facial expressions and the sense of presence obtained in side-by-side interaction The Transparent Video Facetop is a novel user interface concept that supports not only single-user interactions with a PC, but also close pair collaborations, such as that found in collaborative Web browsing, remote medicine, and in distributed pair programming. Facetop seamlessly couples PC desktop co...

Use of video in distributed pair programming was discussed in a workshop at the XP/Agile Universe 2002 conference. This workshop was attended by over 30 people, most of whom had tried some form of distributed pair programming and were working on tools to improve the effectiveness of such activities. The consensus on video was that “webcam” style, postage stamp video – small image and low frame ...

The Network and Computing Services section of Cornell Information Technologies in partnership with the Department of Computer Science is sponsoring a trial for wireless services on campus. Our paper will present an evaluation framework and we report results available in April. Some 100 students and 12 researchers are contributing to the work and it is anticipated that this will roll out into a ...

The importance and use of digital ink in formulas and diagrams is well recognized, and currently utilized by scientific and technical users of pen-enabled computers. Similarly, there is a growing recognition as to the utility of collaborative tools that allow multiple users to edit a document, either simultaneously or asynchronously. Finally, more people are using real-time communication tools ...
