Video Conferencing via IP - prioritising types of data "IP-Based Desktop Video Conferencing This method has several drawbacks. The quality of the audio and video will be dependent on how fast the Internet connections are on the sending and receiving ends. Network congestion on the Internet can also contribute to choppy audio and video." from here... "Prioritization – In networks with even limited amounts of congestion, it may be necessary to prioritize videoconferencing data through the network switches and routers." from here..."Advanced Quality of Service (QoS) Priority queuing ensures high-priority traffic gets delivered efficiently, even during congestion from high traffic bursts. Companies implementing network telephony or video conferencing, for example, need to be able to prioritize such voice and video traffic and other real-time applications over less latency-sensitive traffic to ensure reliability and quality. The ability to prioritize traffic ensures quality of latency-sensitive services and applications despite increasing traffic loads." --- See also http://www.siemon.com/uk/white_papers/03-10-29_voice_over_ip.asp (re: voip but also applies to video conferencing) |
