Ethernet header protocol type

There are several types of Ethernet frames: • Ethernet II frame, or Ethernet Version 2, or DIX frame is the most common type in use today, as it is often used directly by the Internet Protocol. • Novell raw IEEE 802.3 non-standard variation frame WebThe header has information about where the packet comes from and what group of packets it belongs to. Each network protocol attaches a header to each packet. GRE adds two headers to each packet: the GRE header, which is 4 bytes long, and an IP header, which is 20 bytes long. The GRE header indicates the protocol type used by the encapsulated ...
