Using a dedicated line for video conferencing is usually costly. A solution to solve this problem is to use a web-based video conferencing technology. However the existing webbased video conferencing technology needs too much bandwidth which makes two-way exchange of images too slow in the web environment. In this paper, a new web-based video conferencing system is introduced which has overcome this problem by using multicast method. The technique called tunneling which can preserve bandwidth enables this system to do multicast with minimum delay. Thus instead of using dedicated line-based video conferencing, web-based two-way multicasting technology is a better alternative.
