  • Chapter 11 – user datagram protocol
    The Illustrated Network, 2020
    Co-Authors: Walter Goralski
    Abstract:

    In this chapter, you will learn about UDP, one of the major transport layer protocols in the TCP/IP stack. We’ll talk about datagrams and the structure of the UDP header. You will learn about ports and sockets and how they are used at the transport layer.

  • user datagram protocol
    The Illustrated Network, 2009
    Co-Authors: Walter Goralski
    Abstract:

    This user datagram protocol (UDP) is defined to make available a datagram mode of packet-switched computer communication in the environment of an interconnected set of computer networks. This protocol assumes that the Internet protocol (IP) [1] is used as the underlying protocol. This protocol provides a procedure for application programs to send messages to other programs with a minimum of protocol mechanism. The protocol is transaction oriented, and delivery and duplicate protection are not guaranteed. Applications requiring ordered reliable delivery of streams of data should use the Transmission Control protocol (TCP) [2].

  • MIB for the UDP-Lite protocol
    2020
    Co-Authors: Gerrit Renker, Godred Fairhurst
    Abstract:

    This document specifies a Management Information Base (MIB) module for the Lightweight user datagram protocol, RFC 3828. It defines a set of new MIB entities to characterise the behaviour and performance of transport layer endpoints deploying UDP-Lite. UDP-Lite resembles UDP, but differs from the semantics of UDP by the addition of a single option. This adds the capability for variable-length data checksum coverage, which can benefit a class of applications that prefer delivery of (partially) corrupted datagram payload data in preference to discarding the datagram.

  • transport features of the user datagram protocol udp and lightweight udp udp lite
    RFC, 2018
    Co-Authors: Godred Fairhurst, Tom Jones
    Abstract:

    This is an informational document that describes the transport protocol interface primitives provided by the user datagram protocol (UDP) and the Lightweight user datagram protocol (UDP-Lite) transport protocols. It identifies the datagram services exposed to applications and how an application can configure and use the features offered by the Internet datagram transport service. RFC 8303 documents the usage of transport features provided by IETF transport protocols, describing the way UDP, UDP-Lite, and other transport protocols expose their services to applications and how an application can configure and use the features that make up these services. This document provides input to and context for that document, as well as offers a road map to documentation that may help users of the UDP and UDP-Lite protocols.

  • features of the user datagram protocol udp and lightweight udp udp lite transport protocols
    2016
    Co-Authors: Tom Jones, Godred Fairhurst
    Abstract:

    This document describes how the user datagram protocol (UDP) and the Lightweight user datagram protocol (UDP-Lite) transport protocols expose services to applications and how an application can configure and use the features offered by the transport service. The document is intended as a contribution to the Transport Services (TAPS) working group to assist in analysis of the UDP and UDP-Lite transport interface.

  • the lightweight user datagram protocol udp lite
    RFC, 2004
    Co-Authors: Godred Fairhurst, Mikael Degermark, Stephen Pink
    Abstract:

    This document describes the Lightweight user datagram protocol (UDP- Lite), which is similar to the user datagram protocol (UDP) (RFC 768), but can also serve applications in error-prone network environments that prefer to have partially damaged payloads delivered rather than discarded. If this feature is not used, UDP-Lite is semantically identical to UDP. [STANDARDS-TRACK]

  • RObust Header Compression Version 2 (ROHCv2): Profiles for RTP, UDP, IP, ESP and UDP-Lite
    2008
    Co-Authors: Ghyslain Pelletier, Kristofer Sandlund
    Abstract:

    This document specifies ROHC (Robust Header Compression) profiles that efficiently compress RTP/UDP/IP (Real-Time Transport protocol, user datagram protocol, Internet protocol), RTP/UDP-Lite/IP (user datagram protocol Lite), UDP/IP, UDP-Lite/IP, IP and ESP/IP (Encapsulating Security Payload) headers. This specification defines a second version of the profiles found in RFC 3095, RFC 3843 and RFC 4019; it supersedes their definition, but does not obsolete them. The ROHCv2 profiles introduce a number of simplifications to the rules and algorithms that govern the behavior of the compression endpoints. It also defines robustness mechanisms that may be used by a compressor implementation to increase the probability of decompression success when packets can be lost and/or reordered on the ROHC channel. Finally, the ROHCv2 profiles define its own specific set of packet formats, using the ROHC formal notation.

  • robust header compression rohc profiles for user datagram protocol udp lite
    RFC, 2005
    Co-Authors: Ghyslain Pelletier
    Abstract:

    This document defines Robust Header Compression (ROHC) profiles for compression of Real-Time Transport protocol, user datagram protocol- Lite, and Internet protocol (RTP/UDP-Lite/IP) packets and UDP-Lite/IP. These profiles are defined based on their differences with the profiles for UDP as specified in RFC 3095. [STANDARDS-TRACK]

  • An improved UDP protocol for video transmission over Internet-to-wireless networks
    IEEE Transactions on Multimedia, 2001
    Co-Authors: H. Zheng, J. Boyce
    Abstract:

    Packet video will become a significant portion of emerging and future wireless/Internet traffic. However, network congestion and wireless channel error yields tremendous packet loss and degraded video quality. In this paper, we propose a new complete user datagram protocol (CUDP), which utilizes channel error information obtained from the physical and link layers to assist error recovery at the packet level. We propose several maximal distance separable (MDS) code-based packet level error control coding schemes and derive analytical formulas to estimate the equivalent video frame loss for different versions of user datagram protocol (UDP). We validate the proposed packet coding and CUDP protocol using MPEG-coded video under various Internet packet loss and wireless channel profiles. Theoretic and simulation results show that the video quality can be substantially improved by utilizing the frame error information at UDP and application layer.
