FLOW ENTRY CONFIGURATION METHOD, APPARATUS, AND SYSTEM

摘要

A flow entry configuration method, apparatus, and system are disclosed. The method includes: reporting, by a switch, information about a data packet of a first service to a controller, receiving a flow entry delivered by the controller according to the information and a flow table structure, determining a first target service path matching the flow entry of the first service, determining a target hardware flow table according to a preconfigured correspondence between the service path and a hardware flow table of the switch, and configuring a flow entry of the target hardware flow table according to the flow entry of the first service. Therefore, no matter to which controller the switch is connected, the switch can successfully configure, in the hardware flow table, the flow entry used to implement the first service, so as to successfully process the first service, thereby reducing a probability of failure in service processing.

主权项

1. A flow entry configuration method, comprising:
reporting, by a switch, information about a data packet of a first service to a controller; receiving, by the switch, a flow entry of the first service that is delivered by the controller according to the information about the data packet of the first service and a flow table structure, wherein the flow table structure comprises match fields that are supported by multiple flow tables and actions that are supported by the multiple flow tables, and wherein a match field supported by each of the multiple flow tables comprises a match field of the first service, and an action supported by each of the multiple flow tables comprises an action of the first service; determining, by the switch in a preconfigured service path, a first target service path matching the flow entry of the first service, wherein a match field of the first target service path comprises the match field of the first service, and an action of the first target service path comprises the action of the first service; determining, by the switch, a target hardware flow table according to a preconfigured correspondence between the service path and a hardware flow table of the switch, wherein the target hardware flow table supports a service supported by the first target service path; and configuring, by the switch, a flow entry of the target hardware flow table according to the flow entry of the first service.
