What is UDP?

UDP (User Datagram Protocol) is a connectionless protocol used for transmitting data packets over IP networks. It's known for its speed and efficiency, as it doesn't establish a connection before sending data and doesn't guarantee delivery or order. It is commonly used in applications where speed is more important than reliability, such as streaming video and online games, and DNS lookups.

UDP Competitor Technologies

TCP

TCP is a connection-oriented protocol that offers reliable, ordered data transfer, making it a direct alternative to UDP's connectionless, unreliable approach.

SCTP

SCTP is a reliable transport protocol like TCP, but it provides multi-homing and multi-streaming features, making it a competitor to UDP in specific use cases needing some reliability features.

UDP Complementary Technologies

ICMP

ICMP is used for network diagnostics and error reporting, often used in conjunction with UDP for troubleshooting network issues. It does not provide data transport.

IP

IP is the network layer protocol that UDP relies on to route packets. UDP packets are encapsulated within IP packets.

DNS

DNS can use UDP for smaller queries, and falls back to TCP for larger responses, using UDP for faster transport.
