Slide 6 of 35
Notes:
Above 4-6% packet loss video conferencing becomes irritating, and non native language speakers become unable to communicate.
The occurrence of long delays of 4 seconds or more at a frequency of 4-5% or more is also irritating for interactive activities such as telnet and X windows.
Above 10-12% packet loss there is an unacceptable level of back to back loss of packets and extremely long timeouts, connections may start to get broken, and video conferencing is unusable.
