Notes:
Note that the TCP/IP timeout caused by a packet loss is of the order of 4-5 seconds.
For some newer Internet applications there are other thresholds, for example for voice a threshold appears at about 100ms - above that point, the delay causes difficulty for people trying to have a conversation and frustration grows.
