WebOct 24, 2003 · This purpose of this article is to explain how to send a raw Ethernet packet using C# on a Microsoft platform. A raw Ethernet packet is the complete Layer 2 network frame that is sent to the physical wire. Sending a frame like this allows you to manipulate the target and source MAC addresses and the Layer 3 protocol fields. In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport mechanisms. In other words, a data unit on an Ethernet link transports an Ethernet frame as its payload. An Ethernet frame is preceded by a preamble and start frame delimiter (SFD), … See more A data packet on the wire and the frame as its payload consist of binary data. Ethernet transmits data with the most-significant octet (byte) first; within each octet, however, the least-significant bit is transmitted first.
