RFC-908, dating from way back in 1984, is a good example. Essentially, RDP (reliable data protocol) was proposed as a transport layer protocol; it was positioned in the stack as a peer to UDP and TCP.

Some custom protocols support TCP, too. ExpressVPN's Lightway is a great example, and you'll find both 'Lightway - UDP' and 'Lightway - TCP' options in its Protocol settings box.

[The Backwoods Engineer] tested out a new accessory kit for the STM32-F4 Discovery board. The image above shows two boards communicating with the UDP protocol. Notice the extra PCB into which each … ...

Understanding these protocols is essential for system administrators, network engineers, and even software developers working with networked applications. This article provides an exploration of the ...

Software implementations of UDP-based application protocols DNS, NTP, TFTP, Echo (RFC862), Chargen (RFC864), and QOTD (RFC865) were specifically found to be vulnerable to such network loops.

UDP, on the other hand, is an unreliable transport layer protocol, because it never knows whether or not the recipient of its packets actually receive the data. In short, this example covers UDP, a ...

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.

Apple services use a variety of ports and connections that may not be immediately accessible when used on a corporate network. Here's how to access them on enterprise networks.

For example, UDP does not guarantee delivery, so SIP retransmits the messages. In TCP, such retransmission is really unnecessary (and confusing), so no one should retransmit a message.

For example, where one may use UDP to avoid TCP retransmission after errors, if the entire data must be faultlessly delivered to the application, one needs to actually understand the application. If ...
