US 2017/0302562 A1 · Topological Learning Method and Apparatus for OPENFLOW Network Cross Conventional IP Network

Abstract

A topological learning method and apparatus for an OPENFLOW network cross a conventional Internet Protocol (IP) network. The method includes obtaining, by a controller, M OPENFLOW switch (OFS) ports connected to a same conventional IP network, determining whether there is a logical switch corresponding to the conventional IP network, if the controller determines that there is no logical switch corresponding to the conventional IP network, creating and storing the information about the logical switch, where the information about the logical switch includes related information of the M OFS ports, and related information of each OFS port includes link information in a direction from the port to the logical switch and/or link information in a direction from the logical switch to the port, and managing, by the controller, the logical switch as a common OPENFLOW switch of an OPENFLOW network.

Dependent claims

A topological learning method, comprising:

obtaining, by a controller, M OPENFLOW switch (OFS) ports connected to a common conventional Internet Protocol (IP) network, wherein M is an integer greater than or equal to 2, wherein the conventional IP network comprises a non-OFS, and wherein the conventional IP network does not comprise an OFS;
and
storing information about a logical switch when there is no logical switch corresponding to the conventional IP network, wherein the information about the logical switch comprises related information of the M OFS ports, and wherein the related information of the M OFS ports is obtained according to the M OFS ports and the common conventional IP network, and wherein the related information of each of the M OFS ports comprises link information between the logical switch and a relative one of the M OFS ports.

A controller, comprising:

a memory configured to store instructions;
and
a processor coupled to the memory and configured to execute the instructions to:
obtain M OPENFLOW switch (OFS) ports connected to a common conventional Internet Protocol (IP) network, wherein M is an integer greater than or equal to 2, wherein the common conventional IP network comprises a non-OFS, and wherein the common conventional IP network does not comprise an OFS;
and
create information about a logical switch when there is no logical switch corresponding to the common conventional IP network, wherein the information about the logical switch comprises related information of the M OFS ports, and wherein the related information of the M OFS ports is obtained according to the M OFS ports and the common conventional IP network, and the related information of each of the M OFS ports comprises link information between the logical switch and a relative one of the M OFS ports.
