The IP multicast video conferencing system is one of the products developed under the state-level scientific and technological project: 
“Research on Building Comprehensive Processes and Solutions to Ensure Information Safety and Security for Video Conferencing”, project code KC.01.18, led by Associate Professor Dr. Tran Hong Quan from the Institute of Posts and Telecommunications Science.
This system allows for a maximum of 300 simultaneous conferences, supports all common sound cards and cameras, as well as professional equipment used for video conferencing. It effectively manages user access, enabling conference participants to communicate via voice, video, text (chat), or file exchange. Furthermore, it optimizes transmission by using IP multicast to relay voice and video data.
Notably, to ensure security and safety for the video conferencing system, the scientists involved in the project successfully developed a firewall compatible with IP multicast, an intrusion detection system, and specialized equipment to encrypt the transmission. The product has been successfully tested in internal networks, wide-area networks, and international Internet networks, opening up high application possibilities for enterprise networks, government agencies, as well as facilitating training and remote work.
On June 22, 2006, in Hanoi, the state-level acceptance committee (chaired by Professor Vu Dinh Cu) assessed the project with a grade of B.
