  2. User Datagram Protocol - Wikipedia

    en.wikipedia.org/wiki/User_Datagram_Protocol

    Because both TCP and UDP run over the same network, in the mid-2000s a few businesses found that an increase in UDP traffic from these real-time applications slightly hindered the performance of applications using TCP such as point of sale, accounting, and database systems (when TCP detects packet loss, it will throttle back its data rate usage).

  3. Comparison of file transfer protocols - Wikipedia

    They use one of two transport layer protocols: the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP). In the tables below, the "Transport" column indicates which protocol(s) the transfer protocol uses at the transport layer. Some protocols designed to transmit data over UDP also use a TCP port for oversight.

  4. List of TCP and UDP port numbers - Wikipedia

    en.wikipedia.org/wiki/List_of_TCP_and_UDP_port...

    This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for duplex, bidirectional traffic. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.

  5. Port (computer networking) - Wikipedia

    en.wikipedia.org/wiki/Port_(computer_networking)

    Transport-layer protocols, such as the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), transfer data using protocol data units (PDUs). For TCP, the PDU is a segment, and for UDP it is a datagram. Both protocols use a header field for indicating the source and destination port numbers.

  6. Protocol data unit - Wikipedia

    en.wikipedia.org/wiki/Protocol_data_unit

    Protocol data units for the Internet protocol suite are: The transport layer PDU is the TCP segment for TCP, and the datagram for UDP; The Internet layer PDU is the packet. The link layer PDU is the frame. On TCP/IP over Ethernet, the data on the physical layer is carried in Ethernet frames.

  7. Transport layer - Wikipedia

    en.wikipedia.org/wiki/Transport_layer

    TCP is the more complex protocol, due to its stateful design incorporating reliable transmission and data stream services. Together, TCP and UDP comprise essentially all traffic on the Internet and are the only protocols implemented in every major operating system.

  8. Internet protocol suite - Wikipedia

    en.wikipedia.org/wiki/Internet_protocol_suite

    Session-layer functionality is also realized with the port numbering of the TCP and UDP protocols, which are included in the transport layer of the TCP/IP suite. Functions of the presentation layer are realized in the TCP/IP applications with the MIME standard in data exchange. Another difference is in the treatment of routing protocols.

  9. Transmission Control Protocol - Wikipedia

    en.wikipedia.org/wiki/Transmission_Control_Protocol

    The term TCP packet appears in both informal and formal usage, whereas in more precise terminology segment refers to the TCP protocol data unit (PDU), datagram [15] to the IP PDU, and frame to the data link layer PDU: Processes transmit data by calling on the TCP and passing buffers of data as arguments.
