In telecommunications, a protocol data unit (PDU) is a single unit of information transmitted among peer entities of a computer network. A PDU is composed ... A protocol data unit, or a PDU, is a unit of information that is sent by a protocol at a particular OSI layer. For example, a switch is going to operate on the ...
User Datagram Protocol (UDP) is part of the Internet Protocol suite used by programs running on different computers on a network. UDP is used to send short messages called datagrams but overall, it is an unreliable, connectionless protocol. UDP is officially defined in RFC 768 and was formulated by David P. Reed.

This format is comprised of a consistently formatted packet header diagram, followed by structured explanatory text. It is designed to maintain human readability while enabling support for automated parser generation from the specification document.
Protocol data unit diagram. Encapsulation or layering is the addition of Protocol Control Information (PCI) to a Protocol Data Unit (PDU) by a communications protocol. A protocol data unit ( PDU ) is information delivered ( messages ) as a unit among peer entities of networks containing control information, address information or data. In layered systems,PDU is a significant term related to the initial four layers of the OSI model. In Layer 5 and above, PDU is referred to as data. Information field. Figure 15: OSI Reference Model Data Encapsulation. Each protocol creates a protocol data unit (PDU) for transmission that includes headers required by that protocol and data to be transmitted. This data becomes the service data unit (SDU) of the next layer below it. This diagram shows a layer 7 PDU consisting of a layer 7 header (“L7H”) and application data. A protocol data unit (PDU) is an open-system interconnection (OSI) term used in telecommunications that refers to a group of information added or removed by a layer of the OSI model. Each layer in the model uses the PDU to communicate and exchange information, which can only be read by the peer layer on the receiving device and is then handed ...

Stands for "Protocol Data Unit." A PDU is a specific block of information transferred over a network.It is often used in reference to the OSI model, since it describes the different types of data that are transferred from each layer.The PDU for each layer of the OSI model is listed below. Protocol Data Units and Encapsulation For application data to travel uncorrupted from one host to another, header (or control data), which contains control and addressing information, is added to the data as it moves down the layers. The process of adding control information as it passes through the layered model is called encapsulation.
