Abstract
A network packet processing device includes a hardware-accelerated forwarding circuit and a network processing unit (NPU). The hardware-accelerated forwarding circuit is used to receive a plurality of L4S packets from a network port and send the plurality of L4S packets to another network port through hardware-accelerated forwarding without intervention of a central processing unit (CPU). The NPU is used to perform ECN marking on at least a portion of the plurality of L4S packets.
Claims20
A network packet processing device comprising:
- a hardware-accelerated forwarding circuit, configured to receive a plurality of Low Latency, Low Loss, Scalable Throughput (L4S) packets from a network port, and send the plurality of L4S packets to another network port through hardware-accelerated forwarding, without intervention of a central processing unit (CPU);
- and
- a network processing unit (NPU), configured to perform explicit congestion notification (ECN) marking on at least a portion of the plurality of L4S packets.
A network packet processing method comprising:
- receiving a plurality of Low Latency, Low Loss, Scalable Throughput (L4S) packets from a network port;
- sending the plurality of L4S packets to another network port through hardware-accelerated forwarding, without intervention of a central processing unit (CPU);
- and
- performing, by a network processing unit (NPU), explicit congestion notification (ECN) marking on at least a portion of the plurality of L4S packets.
