Datalink layer breaks IP Datagrams (from Network layer) into smaller chunks (if necessary), which will become the data payload of ethernet frames at Datalink layer. The total size of the ethernet frame must be between 64 bytes and 1,518 bytes (not including the preamble). There is a size limitation for Ethernet Frame. The data packets from layer 3 (Network layer) is moved down to Layer 2 (Datalink Layer) as data moves down the TCP/IP protocol stack at Sender. The format of most widely used Ethernet frame these days is explained below. ![]() ![]() There are different formats available for Ethernet Frame. In this tutorial lesson, you will learn about Ethernet Frame format, Structure of Ethernet frame, Ethernet Frame header fields, Preamble, SFD (Start Frame Delimiter), Source and Destination MAC Addresses, Length, Data/Padding and FCS (Frame Check Sequence).Īs you had learned from previous lessons, "Frame" is the name of data packet at layer 2 (Datalink layer) of five layered TCP/IP model.
