One embodiment provides a network device. The network device includes a a processor including at least one processor core; a network interface configured to transmit and receive packets at a line rate; a memory configured to store a scheduler hierarchical data structure; and a scheduler module. The scheduler module is configured to prefetch a next active pipe structure, the next active pipe structure included in the hierarchical data structure, update credits for a current pipe and an associated subport, identify a next active traffic class within the current pipe based, at least in part, on a current pipe data structure, select a next queue associated with the identified next active traffic class, and schedule a next packet from the selected next queue for transmission by the network interface if available traffic shaping token bucket credits and available traffic class credits are greater than or equal to a next packet credits.

Traffic management

Technologies for bridging between coarse-grained and fine-grained load balancing include a computing node of a cluster computing device and a network controller. The computing node may add a flow entry to a local flow table based on flow information received from the network controller. The computing node may transmit a multicast network packet including the flow information and next hop information to other computing nodes of the cluster device. The computing node may also add a different flow entry to the local flow table and a next hop entry to a local next hop table based on a multicast network packet received from another computing node of the cluster device. The computing node may locally process a network packet received from a remote computing device or forward the received network packet to another computing node of the cluster device based on the flow entries added to the local flow table.

Method and system for traffic metering to limit a received packet rate

A device and method for handling Multiprotocol Label Switching (MPLS) label stacks. An incoming label mapping (ILM) table is stored in a first memory. A received packet's label stack is accessed, and an entry corresponding to a top label of the stack is read from the ILM table. A number of other entries are also read from the ILM table, and these other entries are cached in a second memory.
