5. Questions To Be Answered
How to overcome network congestion
Is it possible to achieve toll quality on the wired network, or do we need to go use a higher bandwidth network such as wireless?.
How do we achieve adequate QoS at the same time as decreasing cost and increasing scalability.

6. Considerations Efficient use of bandwidth
Priority mechanism this type of traffic – TOS in IP4 and Priority field in IP6?
Which protocol gives the best results? RSVP, RTP, RTCP, RTSP, ASF
