Configuring flow classification
Overview
Flow classification organizes packets with different characteristics into different classes by using certain
match criteria. It is the basis for providing differentiated services.
For a multi-core device, the control plane and data plane run on different kernels and threads respectively.
The data plane processes packets based on flows. A flow identifies packets with the same characteristics
(identical quintuple) and processing procedure. The flow classification module marks every packet with
a flow label before sending the packet to the data plane. When the data plane receives the first packet
of a flow, a forwarding entry for the flow is created by the service module. Then, the subsequent packets
can be forwarded based on the forwarding entry to improve forwarding efficiency.
