Abstract

A packet processing method implements a QoS guarantee. The method includes: obtaining a flow identification based on packet attribute information and a flow matching rule, generating a flow policy that includes a correspondence between the flow identification and a flow behavior, determining a forwarding path of a packet including the packet attribute information, sending the flow matching rule to an ingress device of the forwarding path, and sending the flow policy to a first network device on the forwarding path. The ingress device adds the flow identification to the packet including the packet attribute information, and sends the packet. The first network device receives the packet including the flow identification, obtains the flow behavior from the flow policy based on the flow identification, and processes the packet in a packet processing mode corresponding to the flow behavior.

Claims19

Dependent claims

A device comprising:

at least one processor;
one or more memories coupled to the at least one processor and storing programming instructions, wherein the at least one processor is configured to execute the programming instructions to cause the device to:
obtain a flow identification based on packet attribute information and a flow matching rule, wherein the flow matching rule comprises a correspondence between the packet attribute information and the flow identification, and the flow identification is used to identify a packet comprising the packet attribute information;
generate a first flow policy, wherein the first flow policy comprises a correspondence between the flow identification and a first flow behavior;
determine a forwarding path of the packet comprising the packet attribute information;
send the flow matching rule to an ingress device of the forwarding path, to indicate to the ingress device to add the flow identification to the packet comprising the packet attribute information;
and
send the first flow policy to a first network device on the forwarding path, to indicate the first network device to process, in a packet processing mode corresponding to the first flow behavior, the packet comprising the flow identification.
