* 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
