Let’s send some UDP date using Iperf network tool.

Real time protocol which cannot tolerate delay.

Hence UDP depends on IP and ICMP for error reporting. No Error control or flow control is provided by UDP. Unlike TCP, Checksum calculation is not mandatory in UDP. Length: The length of UDP Data + UDP header.Ĭhecksum: Checksum is present to detect error. Example: 4444.ĭestination port: The destination port number of packet. Source port: The source port number of the packet. UDP header is very simple and only 8 bytes. To understand more on TCP please follow below link: So, in conclusion when you can compromise some percentage in reliability but really wanted more speed, UDP is the transport layer protocol you should take. But UDP suffers from the strong reliability unlike TCP. So this feature makes UDP faster than TCP. The basic reason is, UDP is a connection less protocol unlike TCP.

Difference between TCP and UDP can be read from internet. Intention of this article is to analysis UDP packet through Wireshark and understand UDP header practically. User datagram protocol is another famous transport layer protocol than TCP.
