A method of and a network processor unit for processing of packets in a network, the network processor comprising: communication interface configured to receive and transmit packets; at least one processing means for processing packets or parts thereof; an embedded switch configured to switch packets between the communication interface and the processing means; and wherein the embedded switch is configured to analyze a received packet and to determine whether the packet should be dropped or not; if the packet should not be dropped, the switch is configured to store the received packet, to send a first part of the packet to the processing means for processing thereof, to receive the processed first part of the packet from the processing means, and to transmit the processed first part of the packet.

Network processor unit and a method for a network processor unit

A method of and a network processor unit () for processing of packets in a network, the network processor () comprising: communication interface () configured to receive and transmit packets; at least one processing means () for processing packets or parts thereof; an embedded switch () configured to switch packets between the communication interface () and the processing means (); and wherein the embedded switch () is configured to analyze a received packet and to determine whether the packet should be dropped or not; if the packet should not be dropped, the switch is configured to store the received packet, to send a first part of the packet to the processing means () for processing thereof, to receive the processed first part of the packet from the processing means (), and to transmit the processed first part of the packet.

A method to reduce buffer capacity in a processor includes giving the data packets admittance to the processor through at least one interface, storing the data packets in at least one input buffer, and using a packet rate shaper outside of a processing pipeline to control flow of the data packets to the pipeline before the data packets enter the pipeline. First and second data packets are given admittance to the pipeline in dependence on cost information per packet that is dependent upon an expected time period of residence of the first data packet in the pipeline. Cost information dependent upon an expected time period of residence of the second data packet in the pipeline differs from said cost information dependent upon the expected time period of residence of the first data packet in the pipeline.
