    • 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.
    • 公开了一种MAN传输设备的流量控制方法,其中当在接收端的数据传输设备的数据传输端口发生拥塞时,将以太网流控制帧反馈到发送端的传输设备,以执行流控制 的数据传输端口。 当数据传输端口的板卡发生拥塞时,将板级流量控制帧反馈到数据传输端口的报文转发模块,对板进行流量控制。 当板卡的逻辑子信道发生拥塞时,将信道级流量控制帧反馈给数据传输端口的报文转发模块,对逻辑子信道进行流量控制。 所公开的方法包括实现MAN传输设备的流控策略,使MAN流控制策略更为优先,满足复杂以太网MAN传输设备的流量控制服务需求。
