摘要:
A controller performs network-wide congestion control in a split architecture network. The controller receives flow statistics from switches for each entity that communicates via the network. The controller chooses a most congested link as a bottleneck link based on a packet loss rate that is derived from the flow statistics and estimated for each entity on each link of the network. The controller identifies a target path in the network that passes through the bottleneck link and carries the most traffic, and calculates a throttling probability for each sharing entity that shares the target path based on the capacity of the bottleneck link, capacity of the first link of the target path, bandwidth consumption and packet loss rate of each sharing entity. The controller then transmits the throttling probability of each sharing entity to the ingress switch of the target path to reduce the congestion on the bottleneck link.
摘要(中):
控制器在分离式架构网络中执行全网络拥塞控制。 控制器从交换机接收通过网络进行通信的每个实体的流量统计信息。 控制器基于从流量统计导出并针对网络的每个链路上的每个实体估计的分组丢失率,选择最拥挤的链路作为瓶颈链路。 控制器识别网络中通过瓶颈链路并承载最多流量的目标路径,并且基于瓶颈链路的容量计算共享目标路径的每个共享实体的节流概率,第一链路的容量 每个共享实体的目标路径,带宽消耗和丢包率。 然后,控制器将每个共享实体的节流概率发送到目标路径的入口交换机,以减少瓶颈链路上的拥塞。
