Specific embodiment
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 carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
To make the advantage of technical solution of the present invention clearer, the present invention is made specifically with reference to the accompanying drawings and examples
It is bright.
As shown in figure 1, the control method of data message provided in an embodiment of the present invention, is illustrated from control device side,
Methods described includes：
Step 101, control device generate flow table item operation instruction and disappear according to the corresponding relation of match information and operation information
Breath.
Wherein, the flow table item operation instruction message includes the match information and the operation information, the matching letter
The corresponding relation of breath and the operation information is configured in advance, and the operation information includes that self-defining operation is indicated and exchange sets
The standby control command supported, the self-defining operation is indicated for indicating to perform the control command.
Wherein, the flow table item operation instruction message is used to indicate that the switching equipment generates flow table item, so as to will be described
Match information in flow table item operation instruction message is configured in the matching domain of flow table item, by the flow table item operation instruction message
In operation information be configured in the operation domain of flow table item.
Wherein, the corresponding relation with mass data message with the operation information in the match information, for handing over
When exchange device receives data message, if the data message is matched with the match information, can be by the match information
Find corresponding operation information.
Wherein, the operation information is used in switching equipment receiving data message, and is looked for according to the match information
During to the operation information, indicate with self-defining operation in the operation information, indicate that the switching equipment performs the behaviour
Make the control command that switching equipment described in information is supported.Such as described self-defining operation indicates can inform the exchange
Equipment, performs self-defining control command, and the self-defining control command is the switching equipment for pre-setting and props up
The control command held.
Wherein, the corresponding relation of the match information and the operation information is configured in advance, and the configured in advance can
To be the mapping table for being provided with match information and the operation information in advance, the mapping table can be arranged in advance
In the local database of the control device, or it is arranged at other network elements, but is not only limited to this.
Wherein, because the switching equipment has various models and system version, the friendship under different model and system version
Exchange device can support different control commands, such as the display control order of the switching equipment under a certain model and system version
For " show ", and the display control order of another model and the switching equipment under system version is " display ", but is not only limited to
In this.
Step 102, the control device send the flow table item operation instruction message to the switching equipment, so that described
Switching equipment generates flow table item.
Wherein, the matching domain of the flow table item includes the match information, and the operation domain of the flow table item includes the behaviour
Make information, the flow table item is used to indicating the switching equipment when the data message is matched with the match information, according to
The self-defining operation is indicated, to the data message execution control command.
Specifically, because the control device does not know the model and system version of the switching equipment, therefore in order to protect
Demonstrate,proving the control instruction that the switching equipment supported can reach the switching equipment, and the control device is by different model and is
The corresponding flow table item operation instruction message of system version is sent to the switching equipment.
Specifically, there are three domains in the general flow table item, and matching domain, operation domain and data field are stored in matching domain
There are the first-class information of data message, such as match information in the present embodiment；Be stored with the operation domain with matching domain each
The corresponding message of data message head is by the process action message taken, the such as operation information in the present embodiment；The data field is deposited
The information such as the message amount and byte-sized of data message are stored up.
