* 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.
