Embodiment Construction

[0032] In view of the deficiencies in the prior art, the inventor of this case was able to propose the technical solution of the present invention after long-term research and extensive practice. The technical solution, its implementation process and principle will be further explained as follows.

[0033] In the embodiment of the present invention, by extending a newly defined DHCP option, the switch obtains the information of the controller when the switch obtains the network information (IP, gateway, etc.) through the DHCP, so as to configure and connect the controller information. Its methods include:

[0034] The option field of DHCP is extended, and the extension field is at least used to carry information such as IP, port number, protocol information and connection mode of the controller, and the number of controllers contained in the extension field can be one or more.

[0035] When the OpenFlow switch exchanges packets with the DHCP server, it configures and connects...

Abstract

The invention discloses a method for announcing OpenFlow controller information through DHCP, mainly by extending the option field of DHCP, and the extended field is at least used to carry controller information; Carry the controller information to configure and connect. Correspondingly, the present invention also proposes a system for notifying OpenFlow controller information through DHCP. Adopting the technical solution disclosed by the invention can simplify the process of configuring the controller information in the OpenFlow switch, and improve the speed and efficiency of connecting the controller.

Description

technical field [0001] The invention relates to an OpenFlow switch configuration method, in particular to a method and a system for notifying OpenFlow controller information through DHCP, and belongs to the technical field of network communication. Background technique [0002] During the working process of the OpenFlow switch, the flow table and group table used for forwarding, and the Meter used for speed limit are all delivered by the controller, so it is very important to connect to the controller as soon as possible. If you want to connect to the controller, the switch needs to know the IP of the controller, the listening port number, and preferably also the version number of the OpenFlow protocol supported by the controller (the major version numbers of the currently released OpenFlow protocol include 1.0 / 1.1 / 1.2 / 1.3 / 1.4 / 1.5). [0003] A controller connection method commonly used in the prior art is: configure the controller information of the switch through various ...
