I am using Packeteer PacketShaper to shape the traffic,
Audio RTP/UDP/IP mcast is guaranteed with partitioned bandwidth
of 90k for either G.711 or TrueSpeech out of 650k over satellite.
Video RTP/UDP/IP mcast with lower priority than the regular
unicast IP traffic.
Everytime when HTTP GET burst traffic hit from client PC's to the
NT IIS 4.0 server, the video on client PC's all freeze until all
the data go through. The audio always go throught without degrading.
