摘要： A flow control sender includes an ingress port with one or more Class Groups (CG) defined including a shared buffer pool, a shared counter per ingress port per CG tracking an amount of the shared buffer pool utilized by each CG, an ingress port utilization counter per ingress port tracking an amount of the shared buffer pool utilized by the ingress port, and a controller computing a dynamic threshold for each CG, comparing the dynamic threshold of each CG with the ingress port utilization counter, and determining a particular CG experiencing congestion when the ingress port utilization counter is greater than the dynamic threshold for the particular CG. A flow control receiver ceases transmission of data packets to the particular CG experiencing congestion and allows transmission of the data packets corresponding to other CGs.

摘要： A service aware flow control apparatus and method for multiple classes of data packets. A flow control sender includes a buffer of an ingress port per Class Group or Class of Service (COS). A counter per COS tracks an amount of buffer utilization per ingress port per COS, and each counter comprises an XOFF threshold level of congestion and an XON threshold. A controller detects, during transmission of the data packets, a counter associated with a buffer for a particular COS has risen to be greater than or equal to the XOFF threshold level of congestion. A flow control receiver ceases transmission of the data packets to the buffer for the particular COS experiencing congestion and allowing transmission of the data packets corresponding to other COS in the flow control sender.
摘要翻译：一种用于多类数据分组的服务感知流控制装置和方法。流控制发送器包括每个类组或服务等级（COS）的入口端口的缓冲器。每个COS的计数器跟踪每个COS的每个入口端口的缓冲器利用量，并且每个计数器包括XOFF阈值级别的拥塞和XON阈值。控制器在传输数据分组期间检测与特定COS的缓冲器相关联的计数器已经上升到大于或等于XOFF阈值的拥塞水平。流控制接收器停止将数据分组传输到缓冲器，以使特定的COS经历拥塞并允许在流控制发送器中传输与其他COS对应的数据分组。

摘要： Different frames received on a first port are processed by different processing channels in parallel. The processed frames are transmitted to a second port in the same order in which they were received on the first port. The ordering is maintained using a FIFO that receives the number of a processing channel whenever a frame is dispatched to the processing channel. The processing channels are selected to provide frames to the second port in the order of the channel numbers in the ordering FIFO.
摘要翻译：在第一端口接收的不同帧被不同的处理信道并行处理。经处理的帧以与第一端口相同的顺序发送到第二端口。使用FIFO来维护排序，FIFO只要将帧分派到处理通道，就接收处理通道的编号。选择处理通道以按顺序FIFO中的通道号的顺序向第二端口提供帧。
