Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to what the present invention was protected
Scope.
To make the advantage of technical solution of the present invention clearer, the present invention is kept company with reference to the accompanying drawings and examples, and it is bright to describe in detail.
As shown in figure 1, the control method of data message provided in an embodiment of the present invention, is illustrated, methods described includes from control device side：
Step 1 01, control device generate flow table item operation instruction message according to the corresponding relation of match information and operation information.
Wherein, the flow table item operation instruction message includes the match information and the operation information, the corresponding relation of the match information and the operation information is configured in advance, the operation information includes the control command that self-defining operation is indicated and switching equipment is supported, the self-defining operation indicates to be used to indicate to perform the control command.
Wherein, the flow table item operation instruction message is used to indicate the switching equipment generation flow table item, so as to which the match information in the flow table item operation instruction message is configured in the matching domain of flow table item, the operation information in the flow table item operation instruction message is configured in the operation domain of flow table item.
Wherein, corresponding relation with mass data message with the operation information in the match information, for when switching equipment receives data message, if the data message is matched with the match information, corresponding operation information can be found by the match information.
Wherein, the operation information is used to receive data message in switching equipment, and when finding the operation information according to the match information, indicated in the operation information with self-defining operation, indicate that the switching equipment performs the control command that switching equipment is supported described in the operation information.Such as described self-defining operation indicates can inform the switching equipment, performs customized control command, the customized control command is the control command that the switching equipment pre-set is supported.
Wherein, the corresponding relation of the match information and the operation information is configured in advance, the configured in advance can be the mapping table for being provided with match information and the operation information in advance, the mapping table can be arranged in the local database of the control device in advance, or be arranged at other network elements, but it is not only limited to this.
Wherein, because the switching equipment has various models and system version, switching equipment under different model and system version can support different control commands, the display control order of such as a certain model and the switching equipment under system version is " show ", and the display control order of the switching equipment under another model and system version is " d i s p l ay ", but it is not only limited to this.
Step 1 02, the control device send the flow table item operation instruction message to the switching equipment, so that the switching equipment generates flow table item.
Wherein, the matching domain of the flow table item includes the match information, the operation domain of the flow table item includes the operation information, the flow table item is used to indicate the switching equipment when the data message is matched with the match information, indicated according to the self-defining operation, the control command is performed to the data message.
Specifically, because the control device does not know the model and system version of the switching equipment, therefore in order to ensure that the control instruction that the switching equipment is supported can reach the switching equipment, different model and the corresponding flow table item operation instruction message of system version are sent to the switching equipment by the control device.
Specifically, there is the match information in the first-class information of data message that is stored with three domains, matching domain, operation domain and data field, matching domain, such as the present embodiment in the general flow table item；Operation information in behaviour's information, such as the present embodiment；The data field stores the information such as the message amount and byte-sized of data message.
Specifically, it can be sent by 0FDF _ VEND0R_ EXTEN S I 0N message in OpenF l ow protocol messages that the control device, which sends the flow table item operation instruction message to the switching equipment,.
As shown in Fig. 2 the control method of data message provided in an embodiment of the present invention, is illustrated, methods described includes from switching equipment side：
The flow table item operation instruction message that step 201, switching equipment receiving control apparatus are sent.
Wherein, the flow table item operation instruction message includes match information and operation information, and the operation information includes the control command that self-defining operation is indicated and the switching equipment is supported, described self-defined
Operation instruction is used to indicate to perform the control command.
Step 202, the switching equipment generate flow table item according to the flow table item operation instruction message.Wherein, the matching domain of the flow table item includes the match information, the operation domain of the flow table item includes the operation information, the flow table item is used to indicate the switching equipment when the data message is matched with the match information, indicated according to the self-defining operation, the control command is performed to the data message.
The control method of data message provided in an embodiment of the present invention, because control device is according to the corresponding relation of match information and operation information generation flow table item operation instruction message, the operation information includes the control command that self-defining operation is indicated and switching equipment is supported, the self-defining operation indicates to be used to indicate to perform the control command；The control device sends the flow table item operation instruction message to the switching equipment, so that the switching equipment generation flow table item, the flow table item is used to indicate the switching equipment when the data message is matched with the match information, indicated according to the self-defining operation, the control command is performed to the data message.So so that the control command that the switching equipment is supported can be realized in the switching equipment, compared with prior art, the embodiment of the present invention can solve the problem that OpenF l ow switching equipment can only be controlled management by function specified in OpenF l ow agreements to OpenF l ow switching equipment or message, it is impossible to the problem of realizing the function outside the OpenF l ow agreements.
