Hi everyone,

The Ethernet frame is the structure of a data packet used for data transmission over Ethernet. The primary components of an Ethernet frame are as follows:

    Preamble: Consists of 7 bytes and typically carries a 56-bit alternating pattern of 1s and 0s. This helps the receiver synchronize with the data stream.

    Start Frame Delimiter (SFD): 1 byte that carries the pattern 10101011. This denotes the actual start of the frame.

    Destination MAC Address: 6 bytes that specify the MAC address of the device to which the frame should be delivered.

    Source MAC Address: 6 bytes that indicate from which device the frame originated.

    Type/Length: 2 bytes. This field indicates either the protocol type of the payload data (e.g., IP, ARP) or the length of the payload, depending on the context.

    Payload: A field that varies between 46 and 1500 bytes. This contains the actual data being carried, such as an IP packet.

    Frame Check Sequence (FCS): 4 bytes used to check the integrity of the data within the frame. It's used to determine if the frame was corrupted during transmission.

In some modern Ethernet variants, especially those supporting VLANs, there might be additional fields added to this basic structure. However, the ones listed above are the foundational components of an Ethernet frame..

"Platforms established on an EtherNET foundation have become increasingly popular in many sectors of industry. This technology, which is both practical and offers time/place savings, has evolved and branched out over time and has been embedded in third-party platforms as well. Below, we have tried to answer some of the main questions we received from our valued visitors about EtherNET."
