Traffic Management Configuration
Traffic management is required to ensure high quality voice and video calls
when voice, video, and data traffic share the same WAN link. Voice and video
traffic must be prioritized for transmission over data traffic to meet the
stringent jitter, latency and packet loss requirements for high quality voice and
video. The 4300T:
• Automatically prioritizes voice and video traffic over data traffic to ensure
high quality voice and video calls.
• Maximizes WAN link utilization by allowing data traffic to burst up to full
line rate in the absence of voice and video calls.
