UDP and TCP: Which One is Right for You?

UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) are two different communication protocols that are used to transfer data over a network.

UDP is a connectionless protocol, which means that it does not establish a connection with the recipient before sending data. This makes it faster and more efficient than TCP, but also less reliable. UDP is commonly used for real-time applications that require low latency, such as online gaming and voice over IP (VoIP).

TCP, on the other hand, is a connection-oriented protocol that establishes a connection with the recipient before sending data. This makes it slower and less efficient than UDP, but also more reliable. TCP is commonly used for applications that require reliable delivery of data, such as web browsing and file transfer.

In summary, the main difference between UDP and TCP is that UDP is faster and less reliable, while TCP is slower but more reliable. The choice of which protocol to use depends on the specific requirements of the application.

Some servers only support UDP, while others support both UDP and TCP. The OctoVPN client for Windows, iOS, and Android automatically uses the available protocol and prioritizes the one selected in the settings.
