Explain a problem inherent with video teleconferencing (VTC) and explain how it can be resolved.
What will be an ideal response?
All forms of communication over IP networks have some degree of sensitivity to disruption and slowdowns, but video teleconferencing is particularly susceptible. No one wants to sit in on a video conference that continually stops and jitters due to a poor or slow Internet connection. Medianets help to eliminate or reduce this problem. A medianet is a network of (typically) far-flung routers and servers that provide-via quality of service (QoS) and other tools-sufficient bandwidth for VTC. Plus, medianets work with UC servers (or sometime by themselves) to distribute video conferences.
