- * Udp.cpp: Library to send/receive UDP packets.
- *
- * NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
- * 1) UDP does not guarantee the order in which assembled UDP packets are received. This
- * might not happen often in practice, but in larger network topologies, a UDP
- * packet can be received out of sequence.
- * 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
- * aware of it. Again, this may not be a concern in practice on small local networks.
- * For more information, see http://www.cafeaulait.org/course/week12/35.html
