US 10,374,899 B2 · Method and device for reporting OpenFLow switch capability

Abstract

A method and apparatus for reporting a feature of an OpenFlow switch are provided. The method includes: when the OpenFlow switch learns that an OpenFlow controller needs to query for port information, reporting port group identifiers of port groups, to which each port of the OpenFlow switch or each port to be queried by the OpenFlow controller belongs, to the OpenFlow controller, herein the port groups are obtained by grouping ports with different features in the OpenFlow switch based on one or more feature types, and each of the port groups has a port group identifier.

Claims19

Dependent claims

A method for reporting a feature of an OpenFlow switch comprising:

after the OpenFlow switch receives a port information query message sent by an OpenFlow controller, reporting port group identifiers of port groups, to which each port of the OpenFlow switch or each port to be queried by the OpenFlow controller belongs, to the OpenFlow controller, wherein port groups are obtained by grouping ports with different features in the OpenFlow switch for a certain feature type, and each of the port groups has a port group identifier.

An apparatus for reporting a feature of an OpenFlow switch provided in the OpenFlow switch and comprising a processor and a memory, wherein the memory stores processor-executable programs, and the programs comprise:

a first reporting module configured to, after the OpenFlow switch receives a port information query message sent by an OpenFlow controller, report port group identifiers of port groups, to which each port of the OpenFlow switch or each port to be queried by the OpenFlow controller belongs, to the OpenFlow controller, wherein port groups are obtained by grouping ports with different features in the OpenFlow switch for a certain feature type, and each of the port groups has a port group identifier.

Dependencies are inferred from the claim text.
