9.4 Ethernet Access Layers: Component Features
The Ethernet access component features may be divided into three areas:
• Data Path — Responsible for the transmission and reception of IEEE 803.2 Ethernet frames.
The Data Path is performed by IxEthAcc.
• Control Path — Responsible for the control of the MAC interface characteristics and some
learning/filtering database functions. Control Plane functionality is included in both IxEthAcc
and IxEthDB
• Management Information — Responsible for retrieving counter and statistical information
associated with the interfaces. IxEthAcc provides this management support.
