Abstract: Video Conferencing requires high bandwidth, low delay, and video transmission between geographically distributed nodes (users). It is challenging as well as interesting to study high quality video conference and to deliver data through the best internetwork. Presently Google+, iChat and Skype as well as SDN based unicast & multicast video conferencing techniques are in use. In present paper, we propose performance evaluation for present and developing video conferencing techniques. Here Google+, iChat, Skype and SDN based systems are compared amongst metrics like bandwidth, latency, throughput and speed. Comparison between different video conferencing techniques is analyzed technically. It is observed that google+, iChat & Skype are used for intra and internet. We also review the new techniques such as SDN based systems.
