user datagram protocol [‚yüz·ər ′dad·ə‚gram ‚prōd·ə‚kȯl]

(communications)

A communications protocol providing a direct way to send and receive datagrams over an IP network but with few error recovery resources, used mainly for broadcasting over a network, for example, with streaming media.

(protocol)

User Datagram Protocol - (UDP) Internet standard network layer, transport layer and session layer protocols which provide simple but unreliable datagram services. UDP is defined in STD 6, RFC 768. It adds a checksum and additional process-to-process addressing information UDP is a connectionless protocol which, like TCP, is layered on top of IP.

UDP neither guarantees delivery nor does it require a connection. As a result it is lightweight and efficient, but all error processing and retransmission must be taken care of by the application program.

No references found			DNS amplification was first widely publicized about three years ago when computer security experts Gadi Evron and Randal Vaughn published a research paper that examined a scenario in which criminals abuse recursive DNS name servers by using spoofed user datagram protocol (UDP) packets. New style of DNS amplification can yield powerful DDoS attacks by Angela Moscaritolo / SC Magazine Other valuable protocols supported include Address Resolution Protocol (ARP), Internet Control Message Protocol (ICMP), User Datagram Protocol (UDP) and Client Bootstrap Protocol (BOOTP).
