Embodiment 1

[0173]An embodiment of the present invention provides a method for configuring a flow table in an OpenFlow network, the method is based on a control device of the OpenFlow protocol, specifically as figure 1 shown, including:

[0174] 101. Determine the service type to be forwarded by the switching device.

[0175] Specifically, in the OpenFlow network, when the switching device establishes a connection with the control device, the control device first determines the service type that the switching device needs to forward.

[0176] 102. Determine flow table matching capability information corresponding to the service type according to the service type to be forwarded by the switching device and the pre-stored correspondence between the service type and flow table matching capability information.

[0177] Specifically, in the OpenFlow network, the corresponding relationship between the service type and the flow table matching capability information is pre-stored in the control ...

Embodiment 2

[0197] An embodiment of the present invention provides a method for configuring a flow table in an OpenFlow network. The method is based on a control device of the OpenFlow protocol and a switching device connected to it, specifically as image 3 As shown, the method includes:

[0198] 301. The control device determines the service type that needs to be forwarded by the switching device.

[0199] Specifically, in the OpenFlow network, when the switching device establishes a connection with the control device, the control device first determines the service type that the switching device needs to forward.

[0200] 302. The control device determines the flow table matching capability information corresponding to the service type according to the service type to be forwarded by the switching device and the pre-stored correspondence between the service type and the flow table matching capability information.

[0201] Wherein, the flow table matching capability information include...

Embodiment 3

[0313] An embodiment of the present invention provides an OpenFLow control device 1100, specifically as Figure 11 As shown, the control device 1100 includes a service type determining unit 1101 , a flow table matching capability information determining unit 1102 , and a sending unit 1103 .

[0314] The service type determining unit 1101 is configured to determine the service type to be forwarded by the switching device.

[0315] The flow table matching capability information determining unit 1102 is configured to determine the flow table corresponding to the service type according to the service type to be forwarded by the switching device and the correspondence between the pre-stored service type and the flow table matching capability information Match capability information.

[0316] The sending unit 1103 is configured to send a flow table configuration message to the switching device, where the flow table configuration message carries flow table matching capability inform...

Abstract

The present invention provides a flow table configuration method, device and system in an OpenFlow network, which can improve the service switching adaptability of the network system and improve work efficiency. The method includes: the control device determines the service type to be forwarded by the switching device; according to the service type to be forwarded by the switching device and the correspondence between the pre-stored service type and flow table matching capability information, determine the flow corresponding to the service type table matching capability information; sending a flow table configuration message to the switching device, the flow table configuration message carrying the flow table matching capability information corresponding to the service type, so that the switching device, according to the flow table matching capability information, Configure the flow table required by the service type. The invention is applicable to the communication field.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for flow table configuration in an OpenFlow network. Background technique [0002] With the development of communication technology, the pace of innovation in the network field has lagged far behind the server side, and customers need faster and easier configuration of the network, so people begin to focus on programmable networks, SDN (Software Defined Network , software-defined networking) came into being. [0003] SDN is to turn the traditional closed network into an open environment, which can be programmed like a computer, creates an easy-to-manage network virtualization layer, decouples network control from the physical infrastructure, and allows third parties to develop network applications to control the operation of the network. OpenFlow technology is a way to realize SDN, which allows users to define traffic and determine the transmission ...
