What is L2 & L3 Protocol

the OSI Reference Model, this lecture focuses on the Ethernet implementation of layer 2 and the IP implementation of layer 3. Peer layers on separate hosts communicate by the interchange of Protocol Data Units (PDU’s).This is a list of network protocols, categorized by their nearest Open Systems Interconnection (OSI) model layers. This list is not exclusive to only the OSI protocol family. Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.

Ethernet comes in two forms: DIX and 802.3/SNAP. DIX is the original ethernet specified by Digital, Intel and Xerox – hence the name DIX. Later, IEEE introduced a modified format which renamed one byte of the preamble with a Start Of Frame delimiter and replaced the DIX type with a Length field. Since ethernet packets must never be smaller than 64 bytes, small payloads must be padded. The padding must be removed and the length field guides this. DIX depended on the payload having it’s own length field for this purpose. Having removed the type field, 802.3 went on to include a SNAP field just following the old ethernet header which serves this need.

Actually, there are three forms. The original 802.3 first came out with an 802.2 three byte code to follow the old ethernet header. This proved worthless and SNAP was substituted. SNAP and 802.2 are made consistent by assigning certain values to the 802.2 headers which indicate that the SNAP follows. for more info click here.
