Overview
The device supports two IP forwarding modes: flow-based and packet-based.
• Flow-based forwarding—Forwards flows with the same 5-tuple elements (source IP address,
destination IP address, source port number, destination port number, and protocol number) to a
same CPU for processing. This mode takes the first-in first-out rule. It is more suitable for traffic with
strict requirements of packet order such as audio and video.
• Packet-based forwarding—Forwards packets in sequence to different CPUs for processing, even
though they are the same flow. This mode does not ensure packet order.
