video conferencing traffic tends to be much more bursty in nature and is more prone to have an impact on other traffic flows
latency requirements are less stringent for video traffic than for voice traffic
video traffic is less sensitive to dropped packets than for voice traffic
video traffic requires the retransmission capabilities of TCP whereas voice uses UDP
video traffic tends to be much more bursty in nature and is more prone to have an impact on other traffic flows
voice traffic requires the retransmission capabilities of TCP whereas video uses UDP
