Figure 2.1:10 Gigabit Ethernet Architecture
(Courtesy: IEEE 802.3ae Standard)
Figure 2.1 shows the 10 Gigabit Ethernet system as referenced to the seven-layered OSI
model. This system consists of the following layers:
2.4.1 MAC (Media Access Control)
The MAC performs the important function of framing the data bytes coming from the
upper layers. The MAC adds the CRC (Cyclic Redundancy Check) and sends the frame
to the PHY layer. 10 Gigabit Ethernet uses the same frame format as that of 802.3
Ethernet frames to maintain compatibility.
