US 2019/0158387 A1 · METHOD FOR MATCHING FLOW TABLES IN A SOFTWARE DEFINED NETWORKING

Abstract

A method includes a switch of the software defined networking analyzing a header of a package to retrieve at least one related rule field when the switch receives the package, selecting a related flow table according to the at least one related rule field and a plurality of interested rule fields of a plurality of flow tables in the switch, and matching the rule content corresponding to at least one flow entry in the related flow table with the content of the at least one related rule field. The at least one flow entry has the same interested rule field and the at least one related rule field includes the interested rule field of the related flow table.

A method for matching flow tables in a software defined networking (SDN) comprising:

when a switch in the software defined networking receives a package, the switch analyzing a header of the package to retrieve at least one related rule field corresponding to the package;
according to the at least one related rule field corresponding to the package and a plurality of interested rule fields of a plurality of flow tables in the switch, selecting a related flow table from the plurality of flow tables;
and
matching rule content corresponding to at least one flow entry in the related flow table with content of the at least one related rule field corresponding to the package;
wherein:
flow entries in the related flow table have at least one common interested rule field;
and
the at least one related rule field comprises the at least one common interested rule field of the flow entries in the related flow table.

a plurality of flow tables;
and
a control unit configured to, when receiving a package:
analyze a header of the package to retrieve at least one related rule field corresponding to the package;
select a related flow table from the plurality of flow tables according to the at least one related rule field corresponding to the package and a plurality of interested rule fields of the plurality of flow tables;
