Abstract: In the subject system for a network switch may receive one or more packets via a set of input ports. The network switch may write the one or more packets into an ingress buffer of an ingress tile shared by the set of input ports. The network switch may read the one or more packets from the ingress buffer according to a schedule by a scheduler. The network switch may forward the read one or more packets to a plurality of output ports.

Abstract: In the subject system for a network switch may determine to transition the output port of the network switch between a store-and-forward (SAF) state and a cut-through (CT) state based on at least one factor. The network switch may determine, based on a condition of the output port, whether to transition the output port to a transition-cut-through (TCT) state or directly to a CT state when transitioning the output port to the CT state. When the output port is transitioned to the TCT state, the network switch may determine, based on the condition of the output port, whether to transition the output port to the CT state or to transition the output port back to the SAF state.

Abstract: A system and method are provided for prioritizing network processor information flow in a channel service manager (CSM). The method receives a plurality of information streams on a plurality of input channels, and selectively links input channels to CSM channels. The information streams are stored, and the stored the information streams are mapped to a processor queue in a group of processor queues. Information streams are supplied from the group of processor queues to a network processor in an order responsive to a ranking of the processor queues inside the group. More explicitly, selectively linking input channels to CSM channels includes creating a fixed linkage between each input port and an arbiter in a group of arbiters, and scheduling information streams in response to the ranking of the arbiter inside the group. Finally, a CSM channel is selected for each information stream scheduled by an arbiter.
