    摘要: A flow control method of MAN transmission equipment is disclosed wherein when congestion occurs in a data transmission port of a data transmission equipment at a receiving end, an Ethernet flow control frame is fed back to a transmission equipment at a sending end, to perform flow control of the data transmission port. When congestion occurs in a board of the data transmission port, a board-level flow control frame is fed back to a packet forwarding module of the data transmission port, to perform flow control of the board. When congestion occurs in a logical sub-channel of the board, a channel-level flow control frame is fed back to the packet forwarding module of the data transmission port, to perform flow control of the logical sub-channel. The disclosed method comprises implementation of flow control strategy of MAN transmission equipment, making MAN flow control strategy more preferable, and satisfying flow control service requirement of a complicated Ethernet MAN transmission equipment.
