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...
in the osi model, each layer adds its own header to the pdu, encapsulating the data from the layer above. this process allows each layer to manage specific tasks and protocols for data transmission. how does a pdu differ from a frame or a packet? a pdu is a generic term that can ...
PDU CODING EXPANSION SYSTEM FOR OSI 6TH LAYERPURPOSE: To save the memory capacity and to improve the processing performance by using the unit of processing not by the unit of PDU but by the unit of SDU of a session layer when PDU coding expansion processing is executed in an OSI 6-th ...
