Abstract
In this technology oriented era, the growing demand of multimedia applications over
the Internet increases with an alarming rate. The application is evolving so does the
networking technologies in order to provide reliable and efficient solutions to the
end users. Multimedia video conferencing is an important part of our life whether in
the academic area, industry or even at homes. Providing efficient and reliable
multimedia video conferencing solution becomes a challenge for the industry
experts and researchers. One of the centers of Universiti Sains Malaysia provided a
multipoint to multipoint video conferencing system that provides good quality
multimedia transmission and with clients connected from any part of the world. This
study intends to explore the possibility of using RTCP protocol with existing MCS
system that uses IP/UDP/RTP communication protocol, in order to provide
reliability. By using RTCP, we will be able to improve the existing system and
Quality of Service (QoS), therefore the amount of packet loss during the multimedia
transmission will be reduced. The same topology was created that projects the real
time MCS topology in order to generate the same point to multipoint video
conferencing in the network simulator NS-2 then compared the existing system with
the enhanced MCS-RTCP system. The present study was justified by doing
quantitative evaluation with the help of plotted graph that shows the enhanced MCS
with RTCP system reduces the packet loss during the multimedia conferencing. This
research work can be extended further as it is highly suitable for the high definition
video conferencing where every detail of frames is important and reduces number of
XIV
packet loss required. Finally, this study has potentials to be much similar in the real
time and is highly scalable and reliable for existing MCS or other video
conferencing systems.
