Assignee: PENSANDO SYSTEMS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. A method comprising:
receiving a network packet at an input port operating at a line rate;
processing the network packet with a line rate classifier circuit that selects an ingress queue that is included in a plurality of ingress queues;
placing the network packet on the ingress queue;
storing the network packet in a packet buffer as one of a plurality of buffered network packets; and
using a sub line rate packet processing circuit to process the network packet after the network packet is stored in the packet buffer,
wherein
the sub line rate packet processing circuit is configured to process the buffered network packets that are selected from the ingress queues,
the line rate classifier circuit and the sub line rate packet processing circuit operate concurrently, and
the line rate classifier circuit is configured to process the network packets at the line rate.
