US 2017/0289026 A1 · SWITCH PROCESSING METHOD, CONTROLLER, SWITCH, AND SWITCH PROCESSING SYSTEM

Abstract

Embodiments of the present invention provide a switch processing method, a controller, a switch, and a switch processing system. The method provided by the embodiments of the present invention is executed by the controller and a logical Switch, where the logical Switch includes at least two physical Switches. The method includes: allocating, by the controller, a flow table of the logical Switch to each physical Switch; sending, by the controller, mapping information, so that each physical Switch obtains the mapping information; and sending, by the controller, flow entries, so that each physical Switch obtains flow entries corresponding to each physical switch and processes a data packet. For the logical Switch for executing the method provided by the embodiments of the present invention, new physical Switches may be stacked on a basis of a physical structure of the logical Switch.

Dependent claims

A switch processing method, wherein the method is executed by a controller and a logical switch, the logical Switch comprises at least two physical Switches, and the method comprises:

allocating, by the controller, a flow table in multiple flow tables of the logical Switch to each physical Switch, wherein the multiple flow tables are a pipeline of the logical Switch;
sending, by the controller, mapping information, so that each physical Switch obtains the mapping information, wherein the mapping information comprises a mapping relationship between the physical Switch and each flow table in the multiple flow tables;
and
sending, by the controller, flow entries to the logical Switch, so that each physical Switch obtains flow entries corresponding to each physical switch and processes a received data packet according to the flow entries or according to the flow entries and the mapping information, wherein the flow entries are content information of each flow table in a flow table set allocated by the controller to each physical Switch.

1 more element

A controller, connected to a logical switch, wherein the logical Switch comprises at least two physical Switches, and the controller comprises:

a processor, configured to allocate each flow table in multiple flow tables of the logical Switch to each physical Switch, wherein the multiple flow tables are a pipeline of the logical Switch;
and
a transmitter, in communication with the processor and configured to send mapping information, so that each physical Switch obtains the mapping information, wherein the mapping information comprises a mapping relationship between the physical Switch and each flow table in the multiple flow tables;
wherein
the transmitter is further configured to send flow entries to the logical Switch, so that each physical Switch obtains flow entries corresponding to each physical switch and processes a received data packet according to the flow entries or according to the flow entries and the mapping information, wherein the flow entries are content information of each flow table in a flow table set allocated by the controller to each physical Switch.
