■

The local switch sends a message to notify the peer switch of stopping sending 
packets to itself or reducing the sending rate temporarily.

■

The peer switch will stop sending packets to the local switch or reduce the 
sending rate temporarily when it receives the message; and vice versa. By this 
way, packet loss is avoided and the network service operates normally.
