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...
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 ...
wiki中的PDU,本文的PDU发生在传输层,也就是 segment for TCP。 OSI model[edit] 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 ...
PURPOSE: 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 layer.TOMISHIGE KAZUHITO...
除了这些，针对逻辑信道复用场景，MAC sublayer可将MAC CE插入TB通过传输信道传送，因此MAC CE就以类似带...
value zero, Then, for each layer, L, in the range 1 through 7, that this node performs transactions for, 2 raised to (L - 1) is added to the sum. For example, a node which performs primarily routing functions would have a value of 4 (2^(3-1)). In ...
