Should I use UDP or TCP?
UDP is faster and more efficient than TCP. Allows you to start data transmission faster without delays or extended waiting times. There is also no need to arrange packets in order or send and receive acknowledgments, saving time. In addition to latency, UDP is also more efficient in terms of throughput.
Do I need both TCP and UDP? You need three TCP packets to make a connection before sending data, while UDP requires only one and is not dependent on an established connection. Additionally, UDP packets are sent individually, while TCP packets use byte streams. WireGuard® only uses UDP, while OpenVPN is compatible with both TCP and UDP.
When should you use a UDP?
The User Datagram Protocol (UDP) is used for time-critical data transmissions such as DNS lookups, online gaming, and video streaming. This communication protocol increases transfer speed by eliminating the need for a formal two-way connection before data transmission can begin.
Why do we prefer TCP over UDP?
TCP is reliable because it guarantees delivery to the destination router. Data delivery to the destination cannot be guaranteed in UDP. TCP provides extensive error checking mechanisms. This is because it provides flow control and data validation.
