Table 3-4 Ethernet parameters for half duplex mode

In full-duplex operation mode, both transmitting and receiving frames are processed simultaneously. This doubles total effective bandwidth. Full duplex is much easier than half duplex because it does not involve media contention, collision, retransmission schedule and padding bits for short frame. The rest functions follow the specification of IEEE802.3. For example, it must meet the requirement of minimum inter-frame gap between successive frames and frame format remains the same as that in the half-duplex operation.

Because no collision will occur in full-duplex operation, there is no mechanism to tell all the involved devices. What will it be if the receiving device is busy and a frame is coming at the same time? Can it use “backpressure” to tell the source device? A function flow control is this introduced in the full-duplex operation.
