WebDec 30, 2016 · Anatomy of a Packet. I hesitate to make specific statements about a technique that can be adapted to such a wide variety of applications; nevertheless, I think it is fair to say that the essential components of a packet are the preamble (aka training sequence), the payload, and the checksum. Preamble. Let’s say you have a 100-byte packet. WebA frame holds one packet of data. The first 8 bytes are the preamble. Some Ethernet systems don't transmit continuously, so the preamble is used to synchronize a receive clock before data is transmitted. In other Ethernet systems, data transmission is continuous, but the preamble has been retained to keep the frame structure.
