* 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 | |||
