User Datagram Protocol (UDP) User Datagram Protocol (UDP) is a connection less transport layer protocol (Layer 4) that are on the internet protocol family.
UDP is basically an interface between IP and upper layer processes. UDP protocol ports distinguish multiple applications running on a device from each other. Unlike TCP, UDP adds no reliability, flow control, or error-recovery functions to IP. Because UDP's simplicity, UDP headers contain fewer bytes and consume less network overhead than TCP.
UDP is useful in situations where the reliability mechanisms of TCP are not necessary, as when a higher layer protocol can error and flow control condition. UDP is the transport protocol for several well-known-application protocol layers, including Network File System (NFS), Simple Network Management Protocol (SNMP), Domain Name System (DNS) and Trivial File Transfer Protocol (TFTP).
UDP packet format contains four fields, This includes areas of source and destination ports, length and checksum.
