The invention discloses a method for realizing congestion control, including: A. to obtain the highest priority service link from the business link congestion in determining the business link congestion data; B. to determine whether the presence of idle bandwidth larger than a business link, the congestion data bandwidth if it exists, gets the lowest priority service link the business link is larger than that from the idle bandwidth congestion data bandwidth, idle bandwidth transmission occupies the business link by the congestion data the highest priority service link; if not, according to the business link without a congested priority, starting from the lowest priority service link, by occupying the business link the idle bandwidth to transmit the data congestion. The invention also discloses a device for realizing the congestion control, and the method and the device can realize the flow congestion control when the port level data is transmitted.

一种实现拥塞控制的方法，其特征在于，该方法包括： Ａ、从发生拥塞的业务链路中获取优先级最高的业务链路，确定所获取业务链路的拥塞数据量； Ｂ、判断是否存在空闲带宽大于所述拥塞数据量占用带宽的业务链路，如果存在，则从所述空闲带宽大于 拥塞数据量占用带宽的业务链路中获取优先级最低的业务链路，占用所获取的业务链路的空闲带宽传输所述优先级最高业务链路的拥塞数据；如果不存在，根据未发生拥塞的业务链路的优先级，从最低优先级业务链路开始，逐级占用所述业务链路的空闲带宽进行所述拥塞数据的发送。
