Udp is the only connectionless tcp/ip protocol at the transport layer.

The transport layer’s primary function is to shield the network’s complexities from the application presentation and session layers. As a result, application developers will focus on developing their applications rather than worrying about how they will interact with the network. This offers greater clarity and independence in the implementation and creation of IP protocol stack components.
Since it is a connectionless protocol, it has minimal error checking, no data recovery functionality for recovering from packet loss, and no retransmissions of packets within and between itself. The end result is best-effort delivery, which means that applications that use UDP will benefit from the low overhead provided by the lack of reliability mechanisms. The word “limited” in the error checking bullet denotes that some error checking will be done in the form of checksums that are sent along with the packets to verify their integrity. A pseudoheader, or tiny header, is also present, which comprises the source and destination ports. As a result, if the service is not operating on a particular computer, UDP will return an error message indicating that the service is unavailable.

Put the UDP packets in a queue, and have a single thread pull them out of the queue and out the pipe (and to receive, have a single thread pulling in any UDP packets received and adding them to an inbound queue).
individual thread that extracts and sends outgoing packages from a stack (und um zu Empfangen, gibt es einen Thread, der alle eingehenden UDP Pakete einsammelt und diese an die Eingehende Queue weiterleitet).
Networks: unit 2 – the application layer – lesson 2
Audio samples are embedded in data packets for transmission over an IP network in VoIP. A single packet of audio usually comprises 10 to 30 milliseconds of audio. TCP and UDP are two of the most widely used Internet connection protocols for data transmission.
Packets of data travel around the Internet. Consider them as letters: The packets come in an envelope with a to/from address, much like letters. TCP and UDP are two different kinds of envelopes. They both transport data and use IP addresses, but the outside envelope is unique. Consider the variations between USPS and FedEx. The IP address of the packet’s origin (source address) and destination (destination address) is written on the envelope (destination address). Since TCP is so widely used on the Internet, it is often combined with IP and written as TCP/IP.
TCP acts as the “FedEx” portion of the previous analogy. When two servers “talk” TCP, a formal connection is created. When one side sends a packet, the other side responds with a packet confirming the packet’s arrival. The packet is re-sent if no acknowledgment packet arrives after a certain period of time or if the acknowledgment notes that there was an issue. It can take a few seconds for a packet to be completely transmitted successfully. TCP is the protocol for WWW sites and email, among other things, and is designed for accuracy rather than timeliness.
Tcp – three-way handshake in details
In this article, we’ll look at how applications use Transmission Control Protocol (TCP) or User Datagram Protocol to send data between two devices (UDP). Through reading this post, you will gain a better understanding of how TCP and UDP function, as well as how they vary from one another. You will also see examples of applications that use these protocols.
The TCP/IP networking model, also known as the networking architecture, involves the transport layer. It includes a detailed collection of documents that detail anything needed to operate a computer network.
The transport layer is in charge of logical communication between applications running on different hosts, as well as providing services to application layer protocols on the TCP/IP network model’s higher layers.
Multiple applications may communicate with each other on a host, whether on a local or remote network. Each application on a host can communicate with another application on a different host, either within a local network or over a remote network, thanks to a mechanism in the transport layer.
