a pdu is a generic term that can refer to data units at various layers of the osi model. a frame is a pdu at the data link layer, while a packet is a pdu at the network layer. each term specifies the layer at which the data unit operates. why is understanding pdus important in ...
PDU拆装模块(PDU Router拆装模块):该模块负责将接收到的PDU进行拆装操作,将PDU拆分为更小的分段或组装多个分段为完整的PDU。这样可以适应不同的网络传输需求。 网络模块(Network Layer):该模块负责与底层网络进行交互,将PDU传输到网络中的目标节点。它负责网络连接管理、数据包的封装和解封装,以及传输的可靠性和效率控...
英文:In network communication, PDU is an important concept describing how data is transmitted between different protocol layers. 中文:PDU的格式和内容取决于它在OSI模型中的哪一层。 英文:The format and content of a PDU depend on which layer it is in the OSI model. 中...
PDUs are relevant in relation to each of the first 4 layers of theOSI modelas follows:[2] Thelayer 1(Physical layer) PDU is thebitor, more generally,symbol(can also be seen as "stream"). Thelayer 2(Data link layer) PDU is theframe. Thelayer 3(Network layer) PDU is thepacket. Th...

OSI reference model uses the term Protocol Data Unit (PDU) for a specific block of information from a specific layer, which is transferred over the network from sender to receiver. Protocol Data Unit (PDU) is often used in reference to the OSI reference model. A Protocol Data Unit (PDU) ...
Protocol data units of theOSI modelare:[1] The Layer 4:transport layerPDU is thesegmentor thedatagram.(段/报文,统称报文段) The Layer 3:network layerPDU is thepacket.(分组(包)) The Layer 2:data link layerPDU is theframe.(帧)
Stands for "Protocol Data Unit." A PDU is a specific block of information transferred over anetwork. It is often used in reference to theOSI 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 belo...
The invention relates to a method of identifying a protocol data unit in a network layer of an air interface in a cellular radio network, to a cellular radio network and to a protocol data unit. A network layer usually includes connection management, mobility management and radio resources ...
