    摘要： In a method for allocating physical queues of a network forwarding element, a request is received at the network forwarding element, the network forwarding element including a plurality of physical queues, where each physical queue of the plurality of physical queues has a fixed bandwidth, the request identifying an allocation of a plurality of virtual queues at the network forwarding element. Based at least in part on the request, a configuration of the plurality of physical queues to the plurality of virtual queues is determined. The plurality of physical queues is configured according to the configuration, wherein the configuring includes allocating at least two physical queues to a virtual queue.

    摘要： Some embodiments provide a method for a traffic management circuit of a data plane forwarding circuit. The traffic management circuit receives data messages from a set of ingress pipelines and provides the data messages to a set of egress pipelines. The method identifies a flow control event. The method provides metadata regarding the flow control event to a message generation circuit of the data plane forwarding circuit via a bus between the traffic management circuit and the message generation circuit.

    摘要： Some embodiments provide a method for scheduling a packet to be dequeued to a processing pipeline of a hardware forwarding element. The method selects a node representing one of multiple ports associated with the processing pipeline. For each of one or more layers of logical queues, the method (i) identifies a set of logical queue nodes associated with a previously selected node based on a configuration that maps multiple physical queues to the multiple ports via the one or more layers of logical queues and (ii) selects one of the identified logical queue nodes based on properties of the identified logical queue nodes. The method selects one of a set of physical queues associated with a selected logical queue node of the last layer of logical queues. The method dequeues a next packet from the selected physical queue for processing by the processing pipeline.

    摘要： Some embodiments provide a method for a traffic management unit of a network forwarding integrated circuit (IC). The traffic management unit includes multiple queues for storing packets. Each stored packet is (i) received by the traffic management unit from one of multiple ingress packet processing pipelines and (ii) for processing by an egress packet processing pipeline after being released from the queue storing the packet. The method determines that a particular one of the queues has crossed a threshold amount of stored packet data. The method provides queue state data including an identifier of the particular queue and a current amount of data stored in the particular queue to at least a subset of the multiple ingress pipelines. The ingress pipelines use the provided data to process subsequent packets.
