Next, you learn about the 4-layer IP stack and differences between the transport-layer protocols Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).

TCP is a byte-oriented protocol, and UDP is message-oriented. The majority of applications are message-oriented, and applications using TCP have to jump through hoops, such as sending the message ...

In the world of Linux networking, protocols play a crucial role in enabling seamless communication between devices. Whether you're browsing the internet, streaming videos, or troubleshooting network ...

These protocols try to improve upon TCP and UDP and add congestion control and optimized throughput forwarding performance. Some of these protocols are esoteric and handle rare corner cases.

Resurrecting UDP The sibling of TCP is called UDP, and it isn’t necessarily designed to play well with others. As a very simple, low-level internet protocol, at least when compared to TCP, the UDP ...

If it uses the UDP protocol to send and receive data, it will use a UDP port. Figure 1, below, is a represenation of an IP address split into its many TCP and UDP ports.

New so-called reliable UDP solutions offer an alternative to TCP. But are they worth the time or money to implement?

SCTP vs. TCP Delay and Packet Loss Stream Control Transmission Protocol (SCTP) is a new transport layer protocol, proposed by IETF in RFC 4960.

UDP’s (and QUIC’s) counterpart in the protocol world is basically TCP (which in combination with the Internet Protocol (IP) makes up the core communication language of the Internet).

Optimizing a VPN isn't just about picking a protocol - choosing UDP or TCP can make a big difference, too.
