单词 Ethernet packet
释义

Ethernet packet

英语百科

Ethernet frame

The most common Ethernet Frame format, type II

A data packet on an Ethernet link is called an Ethernet packet, which transports an Ethernet frame as its payload.

An Ethernet frame is preceded by a preamble and start frame delimiter (SFD), which are both part of the Ethernet packet at the physical layer. Each Ethernet frame starts with an Ethernet header, which contains destination and source MAC addresses as its first two fields. The middle section of the frame is payload data including any headers for other protocols (for example, Internet Protocol) carried in the frame. The frame ends with a frame check sequence (FCS), which is a 32-bit cyclic redundancy check used to detect any in-transit corruption of data.
