A packet processing system comprises a plurality of packet processing nodes configured to process packets. The packet processing nodes are arranged in a plurality of packet processing clusters. The packet processing system also includes a plurality of prefetch buffers respectively associated with different ones of the packet processing clusters. A first prefetch buffer of the plurality of prefetch buffers is associated with a first packet processing cluster and is configured to store packets distributed for processing to the first packet processing cluster when the first packet processing clusters does not include any packet processing nodes available for processing of the packets.

Packet distribution with prefetch in a parallel processing network device

Systems and methods are provided for a network device. A device includes a plurality of packet processing clients. The device further includes a plurality of memories, where a quantity of the memories is greater than a quantity of the packet processing clients, each of the memories storing a replica of data, the packet processing clients being configured to selectively read the control data from any of the memories. An arbiter is configured to select in a first clock cycle for the plurality of packet processing clients a first subset of memories from among the plurality of memories from which to read the control data, and in a second clock cycle, subsequent to the first clock cycle, to select for the plurality of packet processing clients a second subset of memories from among the plurality of memories from which to read the control data.
