    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: 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.
