- Hi,
-
- I have 2 programs, one which broadcasts a bunch of messages, and
- one which reads those broadcast messages. I run the "reader" on 2
- different computers. I then run the "broadcaster" on one of the 2
- computers that is running a "reader". These programs use UDP sockets,
- using a pre-defined port number. The part I'm curious about is that the
- the "reader" not on the same node as the "broadcaster" sees only a small
- percentage of the number of broadcast messages actually sent. I know
- that datagram's are not guaranteed delivery, but why would the percentage
- be so low (around 10%). The "reader" running on the same node as the
- "broadcaster" gets all of the messages every time.
-
- What I'm looking for is just a little better understanding of what's
- going on. I usually broadcast about 1000 1K messages. No this is
- not what I really need to do, but this test program has got me
- curious. Any info on reference material would also be appreciated.
