On an intelligent computing data center network, network administrators deploy various intelligent lossless network technologies such as PFC to implement a high-speed and low-latency lossless network. Which of the following statements are false about the working principles of PFC? (Choose all that apply.)

1. A. After PFC is deployed, the receive end sends PFC packets to the transmit end when the buffer is full, requesting the transmit end to reduce the packet sending rate.
2. B. After backpressure is triggered, the receive end sends PFC stop packets to the transmit end only after the buffer of the receive end is cleared. — đáp án hiện tại
3. C. After PFC is deployed, the receive end sends PFC packets to the transmit end when the received traffic exceeds a certain buffer threshold, requesting the transmit end to reduce the packet sending rate.
4. D. After backpressure is triggered, the receive end sends PFC stop packets to the transmit end as long as the buffer of the receive end decreases to a certain extent. — đáp án hiện tại
