UDP
A core transport-layer protocol of the Internet that provides connectionless, unreliable datagram transmission. Characterized by low latency and high throughput, it is commonly used in real-time communications, streaming media, and similar scenarios.
Timeline (last 90 days)
Under the same protocol (TCP/UDP), the same port can be listened on by only one process at a time, otherwise an "Address already in use" error is triggered.
Flight simulator network synchronization is almost entirely built on UDP, because position packets are sent at high frequency and occasional packet loss is acceptable, whereas TCP's reliable transmission introduces unnecessary latency and overhead.
Flight simulators typically mix protocols: high-frequency state such as position and velocity goes over UDP, while one-off events such as navigation light switches and weapon firing go over TCP or a reliable UDP channel.
TCP provides a reliable, ordered data stream, but at the cost of head-of-line blocking and unpredictable latency; UDP is a best-effort transport that does not guarantee delivery or order, and has no congestion control.
QUIC is a transport layer protocol running on top of UDP, with built-in TLS encryption, multiplexing, and flow control; compared with TCP it can reduce the number of round trips for connection establishment and is more tolerant of packet loss.
Because UDP multicast allows shared sockets, Fabien's team could cover all platforms with a single unified Rust implementation, no longer needing to maintain a separate one for Mac.
In loopback testing, TCP sent 450 packets and received 450 packets with no packet loss, UDP sent 1194 and received 1194 with no packet loss, and both supported jumbo frames (sending and receiving 3695 bytes).
