  • Dynamic prioritized fair share scheduling scheme in over-subscribed port scenario
    Patent number: 9054996
    Abstract: A network device receives initial policer limits for a plurality of over-subscribing ingress ports, where the initial policer limits are based on existing bandwidth limits for an over-subscribed egress port associated with the over-subscribing ingress ports. The network device receives a high threshold watermark and a low threshold watermark for bandwidth usage of the over-subscribed egress port, and identifies a queue, associated with the over-subscribed egress port, with values outside the high threshold watermark or the low threshold watermark. The network device reduces the initial policer limits for the plurality of over-subscribing ingress ports when the queue has values above the high threshold watermark, and increases the initial policer limits for the plurality of over-subscribing ingress ports when the queue has values below the low threshold watermark.

  • Accurate measurement of packet size in cut-through mode
    Patent number: 8462815
    Abstract: A network device operating in a cut-through mode receives a current packet of an unknown length and determines if there is a known length value of a previous packet in a processing cycle associated with the current packet. When there is no known length value of the previous packet, the network device applies, to the current packet, an estimated length value for the current packet. When there is a known length value of the previous packet, the network device applies, to the current packet, the known length value of the previous packet. The network device processes the current packet based on one of the estimated length value or the known length value of the previous packet.
