📝SCTP
Stream Control Transmission Protocol (SCTP) is a transport-level protocol (same as TCP/UDP) for reliable in-order transmission of messages (like UDP) with congestion control.
It’s somewhat between TCP and UDP (or rather an improvement of both).
| TCP | UDP | SCTP | |
|---|---|---|---|
| Reliability | Reliable | Unreliable | Configurable |
| Delivery | Ordered | Unordered | Configurable |
| Transmission | Stream | Messages | Messages |
| Flow control | Yes | No | Yes |
| Congestion control | Yes | No | Yes |
SCTP is used for WebRTC Data Channels.
