Abstract: 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.

Abstract: A broadcast transmission will generate a packet storm in a mesh network, which will last for a very long time and block the network for other traffic. There is a parameter in a broadcast control mechanism named radius which controls the duration of the packet storm. The invention proposes to dynamically select the smallest radius to reduce the packet storm to a minimum, by reporting the smallest possible radius parameter for the broadcast control mechanism. Each device or node of the network comprises a neighbor table for tracking which of its neighboring devices or nodes has successfully relayed the broadcast transmission. Additionally, each device or node comprises a broadcast transaction table to keep a record of any new broadcast transmission or transaction that is either initiated locally or received from a neighboring device or node.
