TCP vs UDP
Difference between TCP (Transmission Control Protocol) and UDP (User Datagram Protocol)
TCP and UDP are two different transport layer protocols that are commonly used in network communications. Understanding the difference between TCP and UDP is essential in determining the transport layer that best suits the requirements of the VMess protocol.
TCP is a connection-oriented protocol that guarantees reliable data transmission. It establishes a connection between the sender and the receiver, ensuring that all packets are delivered in the correct order. TCP provides features such as error checking, flow control, and congestion control to ensure the integrity and efficiency of data transmission. However, the reliability and additional features of TCP come at the cost of increased overhead and latency.
On the other hand, UDP is a connectionless protocol that does not provide reliability guarantees. It sends packets without establishing a connection, allowing for faster and more efficient transmission. UDP is often used in applications where real-time data is crucial, such as video streaming or online gaming, as it prioritizes speed over reliability. However, UDP does not offer error checking or flow control, making it more susceptible to packet loss or corruption.
