Abstract: A method and system for controlling a plurality of sub-pipes in a computer network is disclosed. The computer network includes at least one switch. The plurality of sub-pipes utilizes the switch for transmitting traffic through the network. The method and system include allowing a minimum flow to be set for each of the plurality of sub-pipes and determining whether congestion exists for the pipe. The method and system also include controlling a flow in a sub-pipe of the plurality of sub-pipes only if congestion exists. Once congestion is determined to exist, the time set to control of sub-pipes is set significantly longer than for control over individual decreases or increases of the flows in sub-pipes. The flow is controlled such that the flow for the sub-pipe may be linearly increased if the flow for the sub-pipe of the plurality of sub-pipes is less than the minimum flow. The flow is also controlled such that the flow for the sub-pipe of the plurality of sub-pipes is exponentially decreased if the flow is greater than the minimum flow. In determining whether to increase or decrease the flow in a sub-pipe, a second definition of congestion may be used. Thus the traffic through the switch is stable.

Abstract translation: 公开了一种用于控制计算机网络中的多个子管道的方法和系统。 计算机网络包括至少一个开关。 多个子管道利用交换机来通过网络传输业务。 所述方法和系统包括允许针对所述多个子管中的每一个设置最小流量并且确定所述管道是否存在拥塞。 该方法和系统还包括仅在拥塞存在的情况下控制多个子管道的子管道中的流量。 一旦确定拥挤存在，则设置为控制子管的时间被设置为比控制子管中的流量的个体减少或增加的时间长得多。 控制流量，使得如果多个子管中的子管的流量小于最小流量，则子管的流量可以线性增加。 还控制流量，使得如果流量大于最小流量，则多个子管道的子管道的流量指数下降。 在确定是否增加或减少子管中的流量时，可以使用第二种拥塞的定义。 因此，通过交换机的流量是稳定的。
