It contains the DSAP (Destination Service Access Point) and SSAP (Source Service Access Point) features.Įthernet IEEE 802.3 SNAP: The SNAP (Sub Network Access Protocol) can define more than 256 protocols. To distinguish it from the Ethernet 802.3, its developer added “raw” to its name.Įthernet IEEE 802.3: The maximum compatible protocols that this standard can define is 256. Here are several well-known Ethernet frame formats.Įthernet 802.3raw: It released earlier than the widespread Ethernet 802.3. The modern Ethernet frames were initially used in the Ethernet II before the release of standard IEEE 802.3 in 1983. The first version of Ethernet (known as Ethernet I) based on the 16-bit data fields without defined bytes. The Ethernet frame has developed for years, so it has several variants.

What is MAC? How to find MAC in Windows 10? You can read this post to get the answers. Besides, it includes a 32-bit Cyclic Redundancy Check (CRC), which permits you detect corrupted data. This field usually stores a 4 bytes value that can be applied to examine if the received frame is complete. Frame Check Sequence (FCS): This field is 4 bytes in length.The Data and Pad contains the payload data. The network layer cannot pack data that is less or more than the limit in one packet data of the upper layer. Data and Pad: The minimum size of this field is 46 bytes, while the maximum size is 1500 bytes.

It defines the type of protocols within the frame like IPv4 and IPv6. Type filed: This filed is 2 bytes long.It is useful in identifying the source device. It contains the MAC address of the source device. Source MAC: It has the same length with destination MAC address.It includes the MAC address of the destination device. Destination MAC: This field is 6 bytes long.Start Frame Delimiter (SFD): It means that the destination MAC address field start with the next byte.Preamble: It can inform the receiving system that a frame is beginning and enable synchronization.Now, the explanation to every part of an Ethernet frame will be offered to you. The picture below shows you an example of Ethernet frame so that you will have a basic understanding of the frame structure. They are Ethernet header (Preamble, SFD, Destination, Source and Type), Encapsulated data (Data and Pad), and Ethernet trailer (FCS). In general, an Ethernet frame consists of 3 parts.

The records contain binary code that include essential information like addresses, control information, payload data, as well as checksums.Īccording to the Ethernet standard, Ethernet frames have different structures and contain more or fewer data fields due to the network protocol. The Ethernet frame is divided into several data sets. If so, you can refer to this post to fix it: What Can You Do When Ethernet Not Working on Windows 7/10 The Main Components of Ethernet Frame Sometimes, you may encounter the Ethernet not working, issue. Note: In networking reference models like OSI Seven Layers model and TCP/IP, the Ethernet frames are defined in the data link layer.
