IEEE 802.2
LLC (Logical Link Control)

An IEEE 802 local area network can perform a best effort datagram service, which is enough for some IP packets. The IEEE 802.2 standards define the LLC (Logical Link Control), which identifies four distinct classes of LLC operation enabling it to control the levels of service. Class I provides the data-link connectionless-mode service only. Class 2 provides the data-link-connection-mode service plus data-link-connectionless- mode service. Class 3 provides the acknowledged-connectionless-mode service plus data-link-connectionless-mode service. Class 4 provides the acknowledged-connectionless-mode service plus data-link connection-mode service plus data-link-connectionless-mode service
