OK, I will bite. What is wrong with this comparison of UDP with TCP? As far as I can see the only error is that it implies incorrectly that UDP traffic is not affected by congestion. But it is quite valid in the statement that UDP will tend to crowd out TCP. (Except for short TCP transmissions for which congestion control does not have time to take effect.) Per megabyte of traffic, UDP will tend to cause more delay to other traffic stream than will TCP. What am I overlooking? Roger Bohn P.S. Remember the flap 6 months ago when EUNet basically tried to ban CuSeeMe for exactly this reason. At 6:39 PM -0500 8/28/96, Jeremy Porter wrote: stuff omitted
Under the section "Dirty Secret" "One dirty little secret is that most phone calls and videoconferences ram their way past data transmissions by using a bully of a communications method called UDP. Unlike the more polite Transmission Control Protocol, TCP, which drops back when it detects congestion, UDP continues at full speed, elbowing ahead of TCP traffic. Yet UDP customers aren't paying anything extra for their fast lane". Sigh, you should see the section on peering. Its worse.
