Description / Abstract:
This clause describes the general requirements for 200 Gigabit and 400 Gigabit Ethernet.
200 Gigabit Ethernet uses the IEEE 802.3 MAC sublayer operating at a data rate of 200 Gb/s, coupled with any IEEE 802.3 200GBASE Physical Layer implementation and is defined for full duplex operation only. 400 Gigabit Ethernet uses the IEEE 802.3 MAC sublayer operating at a data rate of 400 Gb/s, coupled with any IEEE 802.3 400GBASE Physical Layer implementation and is defined for full duplex operation only.
Relationship of 200 Gigabit and 400 Gigabit Ethernet to the ISO OSI reference model
200 Gigabit and 400 Gigabit Ethernet couples the IEEE 802.3 MAC to a family of 200 Gb/s and 400 Gb/s Physical Layers. The relationships among 200 Gigabit and 400 Gigabit Ethernet, the IEEE 802.3 MAC, and the ISO Open System Interconnection (OSI) reference model are shown in Figure 116–1.
