Abstract: A network device includes a first port, a second port, and a traffic policer circuit. The traffic policer circuit is configured to provide a frame credit and a credit state associated with the frame credit, receive a start of a first frame of a first stream from the first port, and determine a first estimate frame length of the first frame based on the frame credit and credit state. After the first estimate frame length is generated and prior to an end of the first frame is received, the first frame is metered based on the first estimate frame length to mark the first frame with a first marking. After the end of the first frame is received, the frame credit and credit state are updated based on the first frame. The first frame is forwarded to the second port by policing the first frame based on the first marking.

Abstract: A method, computing device, and non-transitory computer-readable medium for arbitrating data for channels in a video pipeline. The method includes determining arbitration weights for the channels. The method also includes determining which channels have arbitration weights above a threshold. The method further includes issuing data to the channels with arbitration weights above the threshold. The method also includes decrementing arbitration weights for channels for which data is issued. The method further includes repeating the determining, issuing, and decrementing until no channels have arbitration weights above the threshold.
