  • Instead, a request is made to galois, who sends the file in a couple of UDP packets, which is much faster.[1]
  • However, UDP was not made to deal with packet loss or corruption.[1]
  • UDP is a known as a "stateless" protocol, meaning it doesn't acknowledge that the packets being sent have been received.[2]
  • For this reason, the UDP protocol is typically used for streaming media.[2]
  • This page contains a technical definition of UDP.[2]
  • If you find this UDP definition to be helpful, you can reference it using the citation links above.[2]
  • The combination of an IP address and a TCP or UDP port number is called a socket.[3]
  • Data arriving over a UDP connection simply shows up unannounced, like an impolite guest.[3]
  • UDP does not set up a connection between the source and destination.[4]
  • UDP does not guarantee delivery or the correct order of arrival.[4]
  • UDP is used by applications where speed is more important than reliable delivery of the data.[4]
  • An example of applications which makes use of UDP is instant messaging.[4]
  • In computer networking, the UDP stands for User Datagram Protocol.[5]
  • The David P. Reed developed the UDP protocol in 1980.[5]
  • Like TCP, UDP provides a set of rules that governs how the data should be exchanged over the internet.[5]
  • The UDP works by encapsulating the data into the packet and providing its own header information to the packet.[5]
  • In this chapter, you will learn about UDP, one of the major transport layer protocols in the TCP/IP stack.[6]
  • We deploy UDP where the acknowledgement packets share significant amount of bandwidth along with the actual data.[7]
  • Length - Length field specifies the entire length of UDP packet (including header).[7]
  • User datagram protocol (UDP) operates on top of the Internet Protocol (IP) to transmit datagrams over a network.[8]
  • UDP does not require the source and destination to establish a three-way handshake before transmission takes place.[8]
  • UDP is commonly used for Remote Procedure Call (RPC) applications, although RPC can also run on top of TCP.[8]
  • No retransmission delays – UDP is suitable for time-sensitive applications that can’t afford retransmission delays for dropped packets.[8]
  • UDP was defined in RFC 768 and refined in RFC 1122.[9]
  • UDP uses IP protocol ID 17.[9]
  • This does not mean that UDP traffic is somehow lower priority on the network or through routers.[9]
  • It's not as if UDP traffic is routinely tossed by stressed-out routers.[9]
  • For example, UDP enables process-to-process communication, while TCP supports host-to-host communication.[10]
  • UDP provides two services not provided by the IP layer.[10]
  • UDP header composition UDP uses headers when packaging message data to transfer over network connections.[10]
  • UDP headers contain a set of parameters -- called fields -- defined by the technical specifications of the protocol.[10]
  • 사용하여 모든 조각을 UDP 다이어그램으로 다시 조립할 수 있습니다.[11]
  • UDP (User Datagram Protocol) is a communications protocol, used across the Internet.[12]
  • UDP enables process-to-process communication and works by using Internet Protocols to encapsulate data in a UDP packet.[12]
  • contains the source address, the destination address, the protocol, and the UDP length.[13]
  • The UDP module must be able to determine the source and destination internet addresses and the protocol field from the internet header.[13]
  • Such an interface would also allow the UDP to pass a full internet datagram complete with header to the IP to send.[13]
  • UDP is a part of Internet Protocol suite, referred as UDP/IP suite.[14]
  • Here, UDP comes into picture.[14]
  • For the realtime services like computer gaming, voice or video communication, live conferences; we need UDP.[14]
  • Since high performance is needed, UDP permits packets to be dropped instead of processing delayed packets.[14]
  • UDP uses a simple connectionless communication model with a minimum of protocol mechanisms.[15]
  • UDP is a simple message-oriented transport layer protocol that is documented in RFC 768.[15]
  • In this way, UDP provides application multiplexing.[15]
  • A UDP datagram consists of a datagram header and a data section.[15]
  • Applications that do not require reliable data stream service may use the User Datagram Protocol.[16]
  • User Datagram Protocol is used, in place of TCP, when a reliable delivery is not required.[16]
  • However, UDP is never used to send important data such as web-pages, database information, etc.[16]
  • Streaming media such as video, audio and others use UDP because it offers speed.[16]
  • In UDP, this is not built-in into the protocol, and must be handled at a higher level (built on top of it).[17]
  • UDP uses a simple connectionless communication model with a minimum of protocol mechanism.[18]
  • UDP is faster because it does not implement the error detection and correction mechanism that is found in TCP.[19]
  • When using IPv4, the actual limit for the user data is 65,507 bytes – after deducting IP and UDP headers.[20]
  • The UDP header is terminated by the checksum, which is used for error detection during transmission.[20]
  • " If UDP is used in combination with IPv6, the checksum is mandatory.[20]
  • To motivate our discussion about UDP, suppose you were interested in designing a no-frills, bare-bones transport protocol.[21]
  • In fact, if the application developer chooses UDP instead of TCP, then the application is talking almost directly with IP.[21]
  • Note that with UDP there is no handshaking between sending and receiving transport-layer entities before sending a segment.[21]
  • DNS is an example of an application-layer protocol that uses UDP.[21]
  • We also provide performance comparison of the enhanced RUDP against the TCP, UDP, and the standard RUDP counterparts.[22]
  • The User Datagram Protocol (UDP) is a transport layer protocol defined for use with the IP network layer protocol.[23]
  • UDP provides a minimal, unreliable, best-effort, message-passing transport to applications and upper-layer protocols.[23]
  • UDP does not establish end-to-end connections between communicating end systems.[23]
  • UDP does not provide any communications security.[23]
