The reliability of UDP is mainly going to depend on the end nodes you're trying to connect. The backbone of the internet is very reliable and if you're connecting over ethernet or through some other wired connection you'll see very few dropped packets and thus UDP will be very reliable.
If you're connecting with wireless, expect to see some more dropped packets, and if you're connecting with bluetooth expect to see even more (because of its low power bluetooth is more likely to drop packets than either a wifi or wired connection).
- richardwhiuk 12y agoWireless (802.11) has built in re-transmit on a per link basis, so in practice the drop rate isn't as big as you'd expect - the main problem is packet jitter, not loss.
- jeffreyrogers 12y agoAh interesting, I wasn't aware of that. I think the Bluetooth part is still valid however, as is my point about the loss rate being determined largely by how the end hosts are connected to the network core.
