The MAC sub-layer supports two types of frame: IEEE 802.3 frames and Ethernet_II frames. In an Ethernet_II frame, the Type field identifies the upper layer protocol. Therefore, only the MAC sub-layer is required on a device, and the LLC sub-layer does not need to be realized. In an...

According to the Ethernet standard, Ethernet frames have different structures and contain more or fewer data fields due to the network protocol. In general, an Ethernet frame consists of 3 parts. They areEthernet header(Preamble, SFD, Destination, Source and Type),Encapsulated data(Data and Pad)...

The media access control sublayer of Ethernet specifies the MAC addresses of network interfaces, the frame format, and the MAC protocol for sharing the cable. The MAC address of an Ethernet interface card is a 48-bit string set by the manufacturer that is unique to that card. The first 24...
Gigabit Ethernet (GbE), a transmission technology based on the Ethernet frame format and protocol used in local area networks (LANs), provides a data rate of 1 billion bits per second, or 1 gigabit (Gb). Gigabit Ethernet is defined in the Institute of Electrical and Electronics Engineers (IE...
