Access Network Method Comparison in video conferencing

switching does not guarantee ordering and fixed latency, it cannot guarantee a fixed delay and bandwidth. UDP/IP, RTP, RTCP, And RSVP protocols are used to better solve the service quality of real-time communication. Video conferencing systems applied on Broadband IP networks such as ADSL, FTTB, and LAN have achieved good results. As IP networks are everywhere today, this method is easy to build and cheaper. However, the IP address based on Packet Switching follows the best delivery principle.
