"WebWhat are the parts of an Ethernet frame? In general, an Ethernet frame consists of 3 parts. They are Ethernet header (Preamble, SFD, Destination, Source and Type), Encapsulated data (Data and Pad), and Ethernet trailer (FCS). The picture below shows you an example of Ethernet frame so that you will have a basic understanding of the frame structure. " - Data payload of ethernet frame

WebThe maximum frame rate is: Ethernet Data Rate (bits per second) / Total Frame Physical Size (bits) = 812.74 frames per second. The link layer throughput (i.e. number of payload bits transferred per second) is: Frame Rate x Size of Frame Payload (bits) = 812.74 x (1500 x 8) = 9 752 880 bps. This represents a throughput efficiency of 97.5 %.
