I will try to give a short answer without going into details about parts of the header and their use. UDP stands for User Datagram Protocol and is a connectionless network protocol. Jul 03, 2017 · How UDP Works. RELATED: How Latency Can Make Even Fast Internet Connections Feel Slow. The UDP protocol works similarly to TCP, but it throws out all the error-checking stuff. All the back-and-forth communication introduce latency, slowing things down. When an app uses UDP, packets are just sent to the recipient. 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. UDP (User Datagram Protocol) is a communications protocol that is primarily used for establishing low-latency and loss-tolerating connections between applications on the internet. It speeds up transmissions by enabling the transfer of data before an agreement is provided by the receiving party. How TCP and UDP work A TCP connection is established via a three way handshake , which is a process of initiating and acknowledging a connection. Once the connection is established data transfer can begin. User Datagram Protocol (UDP) is a Transport Layer protocol. UDP is a part of Internet Protocol suite, referred as UDP/IP suite. Unlike TCP, it is unreliable and connectionless protocol. So, there is no need to establish connection prior to data transfer. Jan 09, 2017 · Another is called UDP, and it replaces TCP in particular circumstances. Instead of using signals to tell senders that data has been received, UDP just sends the data, resulting in a slightly smaller packet. For that reason, it’s sometimes used in applications like gaming and video communications. So how do TCP and IP work together?

A last point to notice here is that the latency starts to impact packet reorder. The UDP protocol doesn’t care about the packet order but the TCP protocol does. This is another reason why UDP is generally recommended. Now, let’s focus on these packet reordering statistics. Fourth Example: UDP vs TCP with 10% packet reorder ratio
