Message-ID: <89Dec14.092848est.57429@ugw.utcs.utoronto.ca> Date: 14 Dec 89 14:19:09 GMT References: Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 17 How unreliable is UDP? How fast is fast. Unreliable does not mean that its not good to use, it just means that you send out a packet. Thats all you know. If the other machine is alive and gets it, it got there. If the other machine isn't running/ listening/too busy/etc. It won't get it. The point is that when you send it, you do not know if it has been received. The reliability of a UDP packet is about as reliable as a single TCP packet. At least when its a UDP packet to a single machine. How reliable is a UDP broadcast????? ======================================================================= Pete Hickey | Convention says that something funny University of Ottawa | goes here.
