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...
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 ...
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...
The invention relates to a method of identifying a protocol data unit in a network layer of an air interface (170) in a cellular radio network; to a cellular radio network; and to a protocol data unit. A network layer usually comprises connection management, mobility management and radio ...
The rapid spread of digitalisation across all industries has forced companies to act quickly and install powerful IT systems at their distributed locations. This applies to core and cloud data centres as well as edge data centres on the network periphery. Security and availability ar...

The rapid spread of digitalisation across all industries has forced companies to act quickly and install powerful IT systems at their distributed locations. This applies to core and cloud data centres as well as edge data centres on the network peripher...
Overview In the previous chapter, we looked at the application layer and saw that it is the interface between the human network and the data network. In this chapter, we will look at the transport layer and discuss how it aids in communication. At the end of this chapter, you should be...
The structure and fields of the MCS Channel Join Request PDU are specified in section 2.2.1.8. Multiple MCS Channel Join Request PDUs are sent to join the following channels: User Channel (the MCS channel ID is stored in the User Channel ID store (section 3.2.1.5)). I/O channel...
