WebMaximum transmission unit. In computer networking, the maximum transmission unit ( MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. [1] The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer, e.g. Ethernet frame . WebTCP/IP carefully defines how information moves from sender to receiver. First, application programs send messages or streams of data to one of the Internet Transport Layer Protocols, either the User Datagram Protocol (UDP) or the Transmission Control Protocol (TCP).These protocols receive the data from the application, divide it into smaller …

Web11 nov. 2024 · A frame contains more information about the transmitted message than a packet. In networking, there exist two types of frames: fixed-length and variable-length frames. In fixed-length framing, the size of the frame works as the delimiter. Hence there is no need to set a boundary for the frame. WebThe L3 header (to the same frame as above) has the Protocol field, which tells the receiving node how to interpret the next set of 1's and 0's that follow the IP header: Again, without this, how would the receiving entity know to interpret those bits as an ICMP packet?
