An apparatus is described having a plurality of network processors that identify, for each of a plurality of packets, which multidimensional queue from amongst a plurality of multidimensional queues that each one of the plurality of packets should be enqueued into. Each of the network processors is able to identify a particular multidimensional queue for a different one of the plurality of packets.

Method and apparatus for using multiple network processors to achieve higher performance networking applications

An apparatus is described that includes a plurality of queuing paths. Each of the queuing paths further comprises an input queue, an intermediate queue and an output queue. The input queue has an output coupled to an input of the intermediate queue and the input of the output queue. The intermediate queue has an output coupled to the input of the output queue. The intermediate queue receives data units from the input queue if a state of the input queue has reached a threshold. The output queue receives data units from the intermediate queue if the intermediate queue has data units. The output queue receives data units from the input queue if the intermediate queue does not have data units.

Apparatus and method for queuing flow management between input, intermediate and output queues

According to one embodiment, a network is disclosed. The network includes a source device, a networking hardware machine coupled to the source device, and a destination device coupled to the networking hardware machine. The networking hardware machine receives data packets from the source device and distributes statistics data corresponding to the data packets among multiple internal memory devices.

Mechanism for distributing statistics across multiple elements

A method is described that forms different pieces of a packet and sends each one of the pieces toward a different memory unit amongst a plurality of memory units. Each one of the memory units is managed by a different network processor. The method also receives each of the different pieces, each of the pieces having been read from its respective memory unit of the plurality of memory units.

Method and apparatus for packet segmentation, enqueuing and queue servicing for multiple network processor architecture

A method is described that involves recognizing that an input queue state has reached a buffer's worth of information. The method also involves generating a first request to read a buffer's worth of information from an input RAM that implements the input queue. The method further involves recognizing that an output queue has room to receive information and that an intermediate queue that provides information to the output queue does not have information waiting to be forwarded to the output queue. The method also involves generating a second request to read information from the input RAM so that at least a portion of the room can be filled. The method also involves granting one of the first and second requests.
