Step S10 parses the processing field of the message when controller receives the message of interchanger transmission.
Step S20 determines the field type of the processing field.
Message processing method provided by the invention is applied to SDN (software defined network software defined
Network) field is applied to the scene of SDN in particular by traditional network exchange chip.In the friendship using traditional network chip
When changing planes to meet openflow (open flows) agreement, increase SDN controller, dedicated physics is used between controller and interchanger
Channel connection.Wherein, interchanger can be physical switches or virtual switch, refer in particular to physical switches in the present invention.One
Controller can connect multiple switch, be connected between multiple switch using physical channels such as cable or optical fiber.Work as interchanger
When receiving message (data flow) of computer transmission, interchanger is according to the destination address in message information by message from particular end
Mouth is sent.Wherein, destination address is other computers or other connecting with the interchanger that the interchanger connects
Computer equipment under interchanger.
When controller receives the message of interchanger transmission, to obtain the processing mode of the message and the purpose of transmission
Ground is handled and is forwarded to the message received, and then analytic message, obtains the processing field of message, and determines processing word
The field type of section.Common field type has purpose MAC Address, purpose IP address, source IP address, source MAC etc..
In addition, the message that controller receives is that interchanger is forwarded to the controller, wherein controller configures interchanger
Message forwarding, when the input port of interchanger receives message, forwarded the packet automatically to controller.
The processing field is configured to the corresponding search rule of field type described in the interchanger by step S30,
In, the search rule includes two layers of lookup, three layers of lookup and access control list finding.
According to the type of above-mentioned processing field, the corresponding search rule of processing field of the message is obtained, and will be at this
Reason field configuration is into interchanger in corresponding search rule.Search rule in conventional switch includes two layers of lookup, three layers
Lookup and access control list finding (acl lookup) etc..Interchanger receives configured message, the lookup configured according to message
Rule handles message and is forwarded.For example, then should when the processing field that packet parsing goes out is that purpose MAC Address is equal to 2
The field type of processing field is purpose MAC Address, and the corresponding search rule of target MAC (Media Access Control) address is two layers of lookup, therefore, by message
Configuration is in two layers of lookup into interchanger.MAC Address is searched in searching at two layers and is equal to 2 matched processing operations, using this
The processing operation processing message, obtains port numbers from the port information that message carries, and will handle from the port of the port numbers
Message afterwards is sent.
It should be pointed out that the search rule in conventional switch is not limited in two layers of lookup, three layers of lookup and acl lookup,
It is also possible to that there are other search rules, such as multiprotocol label switching (MPLS) rule.The present invention to the configuration of processing field according to
According to for all search rules present in interchanger under actual conditions, and be confined to pointed out in the present embodiment two layers search, three
Layer is searched and acl lookup.In other words, when, there are when a variety of search rules, the processing field that message is decomposited is matched in interchanger
It sets to other search rules other than two layers of lookup, three layers of lookup and acl lookup and is also attributed to protection scope of the present invention.
Target MAC (Media Access Control) address is carried in the transmission process of data, in the message that generally produces or purpose IP address is come, parsing
MAC Address or purpose IP address in message send data to the MAC Address or the corresponding terminal of purpose IP address.And
MAC Address and purpose IP address are searched using the two layers of lookup and three layers of lookup of interchanger, without using powerful
Acl lookup.
In addition, the list item of two layers of lookup has hundreds of K, the list item of three layers of lookup has tens of K, and the list item of acl lookup has several K.
Therefore, the processing method of message can search huge two layers of list item quantity in the present invention and three layers of lookup use, phase
To in the conventional switch for meeting Openflow agreement in the prior art, the message received is not done and is classified, completely uses ACL
The message processing method of lookup, the present invention in the flow table quantity that interchanger can be supported is extended hundreds times, interchanger be applicable in
Number of users increased significantly so that using traditional die support openflow interchanger use scope it is wider
It is general.
In the present embodiment, when the controller of interchanger connection receives the message of interchanger transmission, message is carried out
Parsing, and the processing field parsed is determined into field type.Processing field is configured to word in interchanger according to field type
The corresponding search rule of segment type, different field type correspond to different search rules, so that each in conventional switch
The searching module of a search rule is utilized.Wherein search rule includes two layers of lookup, three layers of lookup and acl lookup
Deng.The list item of two layers of lookup has hundreds of K, and the list item of three layers of lookup has tens of K, and the list item of acl lookup has several K.Therefore, of the invention
The processing method of middle message can by list item quantity it is huge two layers search and three layers of lookup use, compared with the prior art in
In the conventional switch for meeting Openflow agreement, the message received is not done and is classified, at the message for completely using acl lookup
Reason method extends the flow table quantity that interchanger can be supported hundreds times in the present invention, and the applicable number of users of interchanger obtains
To substantial increase so that supporting the use scope of the interchanger of openflow more extensive using traditional die.
Further, referring to Fig. 3, the processing method second embodiment of message of the present invention is based on above-mentioned first embodiment, institute
Stating step S30 includes:
Step S31 obtains the corresponding field type of each processing field when the processing field is multiple.
Step S32 obtains the corresponding search rule of the processing field according to the field type.
Corresponding search rule is respectively configured in each processing field by step S33.
In the transmission of data, it may appear that while the message for multiple addresses such as carry target MAC (Media Access Control) address, purpose IP address,
At this point, the target terminal of data transmission is while meeting this multiple address.In such cases, it after the parsing of message, obtains a variety of
The processing field of field type.For example, target MAC (Media Access Control) address is 2 in data message, and purpose IP address 3, port 6, then the number
It is 2 matching treatments according to target MAC (Media Access Control) address in flow table item in message and interchanger, while is 3 matching treatments with purpose IP address
Afterwards, it is sent from port 6.
In the present embodiment, for being in the processing for carrying the message of a variety of addresses, when parsing multiple processing fields,
Identify the field type of each processing field.The corresponding search rule of processing field is determined according to field type, then will handle word
Section configures corresponding search rule.For example, containing processing field 1 (target MAC (Media Access Control) address 2, field type in the message received
For purpose MAC Address, search rule is two layers of lookup) and processing field 2 (purpose IP address 3, field type is for purpose IP
Location, search rule are three layers of lookup), then processing field 1 is configured into two layers of search rule, processing field 2 configures three layers of lookup rule
Then.
The processing field for configuring the good search rule is sent to the interchanger, for the friendship by step S34
It changes planes after receiving the processing field, successively searches the processing field according to the lookup priority of the search rule, and
The message is handled according to lookup result.
Controller is the lookup priority of interchanger configuration search rule in advance, when interchanger is received configured with lookup rule
After processing field then, lookup and Message processing are carried out to processing field according to priority is searched.Then, it will successively parse
After all processing fields have configured corresponding search rule, all processing fields are sent to interchanger, so that interchanger
It receives processing field and successively searches processing field according to the corresponding search rule of processing field, and handled according to lookup result
Message.
By the way that processing field is decomposed into a plurality of types of processing fields, it is redistributed to a variety of search rules and carries out processing word
The lookup of more complicated processing field is realized in the lookup of section and the processing of message using relatively simple search rule combination,
It reduces and the list item of complicated search rule is occupied, also cannot achieve the place of that class message of lookup for the combination of simple search rule
Reason, reuses the less complicated search rule of list item, and reasonable disposition search rule avoids the waste of the use space of interchanger,
Improve the service quality of interchanger.
Wherein, when interchanger searches processing field according to the search rule of configuration, the feature of processing field is obtained
Value searches in search rule and is worth matched lookup address with this feature, and then obtains the corresponding processing operation in lookup address,
The message is handled according to the processing operation.In addition, if there is no the matched lookup ground of this feature value under the search rule of configuration
When location, typically directly dropping packets, not further to be handled.
In addition, according to the rule that complexity is incremented by and list item quantity is successively decreased is searched, the lookup in interchanger is preferential
The priority that grade is configured to two layers of lookup, three layers of lookup and access control list finding successively reduces.If having configuration in message
It is preferential to search the processing field for being configured to two layers of lookup when the processing field searched for two layers and the processing field of three layers of lookup,
Respective handling is carried out to message after matching and then carries out three layers of lookup, respective handling is carried out to message after matching, finally, will
The message handled is sent by corresponding output port.
In the present embodiment, when parsing multiple processing fields, the field type of each processing field is identified.According to word
Segment type determines the corresponding search rule of processing field, then processing field is configured corresponding search rule.Controller is in advance
Interchanger configures the lookup priority of search rule, after interchanger receives the processing field configured with search rule, according to
It searches priority and lookup and Message processing is carried out to processing field.Then, successively all processing fields parsed are being configured
After corresponding search rule, all processing fields are sent to interchanger so that interchanger receive processing field according to
The corresponding search rule of processing field successively searches processing field, and handles message according to lookup result.By the way that word will be handled
Section is decomposed into a plurality of types of processing fields, is redistributed to a variety of search rules and carries out the lookup of processing field and the place of message
Reason is realized the lookup of more complicated processing field using relatively simple search rule combination, reduced to complicated search rule
List item occupy, reasonable disposition search rule avoids the waste of the use space of interchanger, improves the service quality of interchanger.
Further, referring to Fig. 4, the processing method 3rd embodiment of message of the present invention is real based on the above-mentioned first or second
Example is applied, after the step S33, further includes:
Step S35 obtains the search rule of the processing field configuration and the characteristic value of the processing field respectively.
Step S36 obtains processing operation of each characteristic value in the corresponding search rule.
Step S37 adds pretreatment operation in the processing operation according to the priority of the search rule, wherein
The default processing operation includes one added in loopback mark and removal loopback mark, and the interchanger is recognized with institute
When stating the message of loopback mark, the message is sent to the Message processing entrance of the interchanger.
In the present embodiment, the loop fuction of controller configuration interchanger, after interchanger is configured with loop fuction, exchange
When the message processing module (MPM) of machine detects the message of loopback mark, the message is back to the Message processing entrance of interchanger,
The message is carried out to the matched and searched of search rule once again.For that can be better achieved to the different search rules of configuration
Processing field successively carries out lookup and Message processing, when handling message according to the lookup result of a upper processing field, described
Winding mark is added in message, so that the message is back to Message processing entrance, carries out the lookup of next processing field.Most
Winding in the message is identified removal, the winding of end message after searching by the latter processing field, so that message is from defeated
Exit port output.
Specific implementation is, after corresponding search rule is respectively configured in processing field, obtains each processing respectively
The search rule of field and the characteristic value of processing field.The corresponding processing operation of this feature value is found in search rule, is pressed
Default processing operation is added in processing operation according to the priority of the search rule.Default processing operation includes addition winding mark
With removal winding mark.Wherein, winding mark can be addition winding in messages and add than the addition manner that top grade identifies, with
And it is removed using corresponding removing method.
For example, containing processing field 1, (target MAC (Media Access Control) address 2, field type is for purpose MAC in the message received
Location, search rule be two layers lookup), processing field 2 (purpose IP address 3, field type be purpose IP address, search rule
Searched for three layers) and processing field 3 (source MAC 4, field type are source MAC, and search rule is acl lookup), it is defeated
Exit port is 6.The then processing behaviour by target MAC (Media Access Control) address in two layers of lookup to increase " addition winding mark " in 2 processing operation
Make, after the processing field 1 for having matched two layers of lookup, by message addition winding mark, so that message winding, carries out three
Layer is searched.The processing operation for increasing " addition winding mark " in the processing operation that purpose IP address is 3, so that message is carrying out
After three layers are searched corresponding operation processing, loopback carries out acl lookup, after being finally completed acl lookup, winding is identified and is removed, knot
The winding of beam message, and message is exported from output port 6.
Wherein, the default processing operation of addition is addition winding mark or removing the judgment method of winding mark is root
According to the priority of the search rule, when adding pretreatment operation in the processing operation, the processing field configuration is obtained
Search rule lookup priority, when it is described lookup priority be the processing field configuration search rule in maximum it is excellent
When first grade, illustrate that there is also processing fields after this processing field, then adds in the corresponding processing operation of the described processing field
The default processing operation added is addition loopback mark, so that carrying out the lookup of next processing field after message winding；Work as institute
When stating the minimum priority in the search rule that lookup priority is the processing field configuration, illustrate that this processing field is last
One processing field required to look up, the then processing operation that addition removal loopback identifies in the processing operation of this feature value, knot
The winding of beam message, so that message be exported from output port.It is easily understood that being intermediate processing for searching priority
Field, when according to lookup result by Message processing, returning for message is can be realized in the addition without carrying out winding mark to message
Ring.
In the present embodiment, after corresponding search rule is respectively configured in processing field, each processing word is obtained respectively
The search rule of section and the characteristic value of processing field.The corresponding processing operation of this feature value is found in search rule, according to
The priority of the search rule adds default processing operation in processing operation.Default processing operation include addition winding mark and
Remove winding mark.So that winding mark is added in the message when handling message according to the lookup result of processing field,
So that the message is back to Message processing entrance, the lookup of next processing field is carried out.It is searched in the last one processing field
The winding in the message is identified into removal, the winding of end message later, so that message is exported from output port.Realize message
The processing of middle processing field successively searched with message.
In addition, the embodiment of the present invention also proposes that a kind of processing unit of message, the processing unit of the message include: storage
