IEEE 802.3 Ethernet Data Link Control Overview

IEEE 802.3 Ethernet data link control (DLC8023) is a device manager that follows the generic data link control (GDLC) interface definition.

This DLC device manager provides a passthrough capability that allows transparent data flow and provides an access procedure to transfer four types of data over an Ethernet local area network (LAN):

• Datagrams
• Sequenced data
• Identification data
• Logical link controls.

The Ethernet device handler and the Ethernet high performance LAN adapter transfer data.
