In some embodiments, as shown in Figure 1, may include configurations module 111 and business on SDN controller 110 112 two major classes of configuration module, wherein configurations module 111 and business configuration module 112 are opposite and say, for example, basic Configuration module 111 and business configuration module 112 can be the configurations module and business configuration module of first network, can also be with It is the configurations module and business configuration module of the second network, which is made of at least one network equipment, and second Network is the virtual network created based on first network.

Since the configuration data managed on SDN controller is more and complicated, if 110 configuration data of SDN controller is abnormal, For example, the configuration data in SDN controller 110 occurs lacking or the abnormal conditions such as mistake, administrator carry out reconfiguring needs More manpower and material resources are expended, the time of abnormal allocation data recovering is longer, and the stability of network is lower.It is of the invention based on this A kind of SDN controller configuration recovery method and device are proposed in embodiment, there can be configuration data abnormal on SDN controller When, restored by the original configuration data on the corresponding network equipment of the configuration module being abnormal, it is extensive to improve configuration Multiple efficiency reduces the time that configuration restores, improves the stability of network.

In embodiments of the present invention, above-mentioned configuration, which restores to refer to, reverts to normal configuration mould for abnormal configuration module Block, for example, increasing configuration data etc. wrong in the configuration data lacked in configuration module or modification configuration module.

Fig. 2 is a kind of SDN controller configuration recovery method flow diagram provided in an embodiment of the present invention.This method application In SDN controller, as shown in Fig. 2, this method specifically comprises the following steps:

S210, it is if there are the configuration modules of configuration data exception on SDN controller, the configuration module of the exception is corresponding The network equipment be determined as destination network device.

Wherein, abnormal configuration module may include: configurations module and/or business configuration module.

It in some embodiments, include that the configurations module of the second network and/or business are matched with abnormal configuration module For setting module.Configurations module may include virtual link layer network configuration module, virtual router configuration module etc. Deng；Business business configuration module may include firewall configuration data, load balancing configuration data etc..

Wherein, above-mentioned virtual link layer configuration module can be used for configuring access device；

Above-mentioned virtual router configuration module can be used for configuring gateway；

Above-mentioned firewall configuration module can be used for configuring firewall box；

Above-mentioned load balancing configuration module can be used for configuration load equalizing equipment etc..

In addition, the network equipment of same type configurations module or service configuration module for configuration may include one Or it is multiple, for example, virtual link layer configuration module can be used for configuring one or more access devices.

So can be according to the configuration relation between configuration module and the network equipment, to determine that abnormal configuration module is corresponding The network equipment.And the abnormal corresponding network equipment of configuration module is obtained into original configuration number as destination network device According to.

The configuration data of configuration module on SDN controller may include configuration item configuration parameter corresponding with the configuration item Etc..For example, the configuration item of virtual router configuration module may include Virtual Private Network (Virtual Private Network, VPN) and L 3 virtual extension LAN ID (Layer 3Virtual Extensible Local Area Network, l3vni) etc.；The VPN configuration item corresponds to VPN configuration parameter, is specifically as follows 10002；L3vni configuration item is corresponding L3vni parameter, is specifically as follows 10008.

The configuration module of configuration data exception may include the abnormal configuration item of configuration module, configuration parameter exception or match Situations such as setting item and abnormal configuration parameter can also include that configuration module is lost, configuration module is by mistake deletion or configuration mould Situations such as block mistake.

S220 obtains the original configuration data of abnormal configuration module from destination network device.

Wherein, original configuration data can refer to configuration data of the abnormal configuration module before exception.Passing through SDN When controller Configuration network equipment, SDN controller needs the configuration data before exception being issued to the network equipment, the network equipment Configuration data before the exception received may be considered the original configuration data of abnormal configuration module.

In one example, the original configuration data that the network equipment receives can be configuration order.For example, abnormal matches Setting module is virtual router configuration module.It is configuration item in the configuration data of the virtual router configuration module before exception The parameter of VPN is 10002, and the parameter of configuration item l3vni is 10008.SDN controller can pass through the virtual road before the exception Configuration order is generated by device configuration module, and is issued to gateway, which may be considered being somebody's turn to do after there is exception The original configuration data of virtual router configuration module.For example, the configuration order for being issued to gateway can be with are as follows: needs are matched The interface set is " virtual switch interface (virtual switch interface, vsi) 3 "；The configuration order is described as "SDN-vsi-10008"；" 10002 " are configured by IP-VPN；" 10008 " are configured by l3vni；It is configured in the virtual router After configuration data exception occurs in module, SDN controller can obtain the configuration order as the virtual flow-line from the network equipment The original configuration data of device configuration module.

S230 carries out configuration recovery to abnormal configuration module using the original configuration data of abnormal configuration module.

There is the configuration mould of configuration data exception on SDN controller in the above method provided through the embodiment of the present invention When block, the abnormal corresponding destination network device of configuration module is determined, and obtain original configuration data from the destination network device, Configuration module abnormal on SDN controller is restored on the basis of the original configuration data, so that abnormal configuration module Timely restored, ensure that the consistency of SDN controller Yu LA Management Room configuration data, alleviates artificial progress SDN The time delay that abnormal configuration module is restored on controller, and then improve the stability based on SDN networking.

In order to enable all types of configuration datas preferably to distinguish, these configuration modules can it is pre-configured to Mutually distinguish configuration module mark, for example, configuration module mark can for " virtual router (Virtual Router, VROUTE) _ ", being somebody's turn to do " VROUTE_ " is virtual router configuration module mark；For another example configuration module mark can be " fire prevention Wall (FIREWALL) _ ", being somebody's turn to do " FIREWALL_ " is firewall configuration module id.

SDN controller can carry the configuration data when sending configuration data (for example, configuration order) to the network equipment The configuration module of corresponding configuration module identifies, and belongs to which configuration module to identify the configuration data, such as: virtual link The corresponding configuration data of layer network module carries virtual link layer network configuration module mark, which would generally issue To access device；The corresponding configuration data of virtual router configuration module carries virtual router configuration module mark, this is matched Gateway would generally be issued to by setting data；The corresponding configuration data of firewall configuration module carries firewall configuration module mark Know, which would generally be issued to firewall box.Therefore, it can determine to correspond to based on current abnormal configuration module The network equipment, using the network equipment as destination network device after, can be identified with configuration module from the destination network device On get the corresponding original configuration data of configuration module of the exception.

For example, in conjunction with shown in Fig. 3 A, SDN controller 310 may include that virtual router configuration module, virtual router are matched Module and intrusion prevention system configuration module are set, for configuring the network equipment that device type is firewall.SDN controller 310 It may include virtual router configuration module 311, firewall configuration module 312 and intrusion prevention system (intrusion- Preventionsystem, IPS) configuration module 313, SDN controller 310 can be based on above-mentioned configuration module, be set to firewall Standby 320 send configuration order 321, configuration order 322 and configuration order 323.Wherein, configuration order 321 includes configuration module mark Know " VROUTE_ "；Configuration order 322 includes configuration module mark " FIREWALL_ "；Configuration order 323 includes configuration module mark Know " SDN_IPS_ ".

For another example SDN controller 330 includes firewall configuration module in conjunction with shown in Fig. 3 B, it is for configuring device type The network equipment and load balancing configuration module of firewall are used to configure the network equipment that device type is load balancing.SDN Controller 330 may include firewall configuration module 331 and load balancing configuration module 332, and SDN controller 330 can be with base In above-mentioned configuration relation, configuration order 341 is sent to firewall box 340, sends configuration order to load-balancing device 350 351.Wherein, configuration order 341 includes configuration module mark " FIREWALL_ "；Configuration order 351 includes that configuration module identifies " S Load balancing _ ".

In order to preferably show that these above-mentioned configuration datas, can also be in above-mentioned configuration module both from SDN controller The same specific mark, such as " SDN_ " or " SDN/ " etc. are added in mark, the mould is added behind the specific mark The mark of block itself, if the module id of firewall module can be embodied as: SDN_FIREWALL, in this way if configuration number SDN_FIREWALL is carried in, then shows that the configuration data is the configuration data that firewall module issues, belong to service class The configuration data of type can obtain original configuration data with slave firewall equipment, use if carrying out the recovery of the configuration data The original configuration data got correspond to firewall module and are restored.

In some embodiments, since the configuration data on the network equipment can have very much, SDN controller is original in acquisition It may include a variety of acquisition modes when configuration data.

Example (1), above-mentioned S220 can be at least achieved by the steps of:

The first acquisition instruction is sent to destination network device, which carries the first command id；

Reception destination network device is locally stored all original according to the destination network device that the first command id is sent Configuration data, each configuration data in all original configuration data carry configuration module mark；

It is identified according to the configuration module of abnormal configuration module and chooses abnormal configuration mould from all original configuration data The original configuration data of block.

Example (2), above-mentioned S220 can be at least achieved by the steps of:

The second acquisition instruction is sent to destination network device, which carries the second command id and exception Configuration module configuration module mark；

Receive what destination network device was sent according to the configuration module of the second command id and abnormal configuration module mark The original configuration data of abnormal configuration module.

For above-mentioned example (1) or (2), in order to which the network equipment can be better discriminated between when obtaining original configuration data Which configuration module is the configuration data of transmission belong to, and SDN controller is that can carry in the configuration data issued to the network equipment Configuration module mark.

For example, SDN controller sends configuration order to the network equipment, the format of the configuration order can be extensible markup Language (extensible markup language, XML), the configuration order may include configuration name, description, configuration item and The information such as parameter, which may include configuration module mark or the description may include configuration module mark.Example again Such as, what SDN controller issued the configuration order of gateway is described as " SDN-VROUTE-vsi-10008 ", alternatively, SDN is controlled It include the interface that needs to configure is " VROUTE-vsi3 " that device, which issues the configuration order of gateway, should " VROUTE " be router Configuration module mark.

For above-mentioned example (1), destination network device can be according in abnormal configuration module mark and configuration order The configuration module of carrying identifies, configuration order of the selection comprising abnormal configuration module mark in all configuration orders, as The original configuration data of abnormal configuration module, and the original configuration data of abnormal configuration module are sent to SDN controller.

For above-mentioned example (2), destination network device can return to all configuration orders being locally stored, SDN controller It can be identified according to the configuration module carried in abnormal configuration module mark and configuration order, in all configuration orders Configuration order of the selection comprising abnormal configuration module mark, the original configuration data as abnormal configuration module.

In addition, above-mentioned for above-mentioned example (1) or (2), the first command id and the second command id can be identical Mark, or different marks.

In one example, the first command id and second order can be identical mark, first command id or Second command id is used to indicate destination network device and returns to original configuration data, if acquisition instruction does not include configuration module mark Know, that is, does not indicate the original configuration data for returning to which configuration module, then, destination network device returns to the original of whole Configuration data；If acquisition instruction includes configuration module mark, that is, specifies return the original of which configuration module and match Data are set, then, destination network device returns to the configuration module and identifies corresponding original configuration data.

In another example, the first command id and the second command id can be different command ids, wherein the One command id is used to indicate destination network device and returns to all original configuration data, and the second command id is used to indicate target network Network equipment returns to the configuration module that acquisition instruction carries and identifies corresponding original configuration data.

By the acquisition modes of above-mentioned original configuration data, corresponding original match can be found according to abnormal configuration module Data are set, and then targetedly abnormal configuration module is restored according to original configuration data, ensure that original configuration The accuracy of data acquisition, and improve recovery efficiency.

In practical applications, the configuration module on above-mentioned determining SDN controller with the presence or absence of configuration data exception at least may be used To realize one of in the following way:

The exception configuration is restored the configuration module for instructing instruction when receiving abnormal configuration recovery instruction by mode (1) It is determined as abnormal configuration module；

Mode (2) will lose the configuration module of configuration data when detecting in configuration module there are when configuration data loss It is determined as abnormal configuration module；

Error configurations data will be present when detecting in abnormal configuration module there are when configuration data mistake in mode (3) Configuration module be determined as abnormal configuration module.

For aforesaid way (1), with the presence or absence of in an example of abnormal configuration module on determining SDN controller, It can be by receiving the instruction of user's triggering to determine whether there is abnormal configuration module, which can control for the SDN The administrator of device.For example, user when finding configuration data exception, can trigger abnormal allocation data recovering instruction, the exception Allocation data recovering instruction can carry configuration module mark, and exception configuration restores instruction and is used to indicate configuration module mark There are configuration data exceptions for corresponding configuration module, so that SDN controller is after receiving exception configuration and restoring instruction, by this The configuration module that abnormal configuration restores instruction instruction is determined as abnormal configuration module.Wherein, configuration module mark can wrap Include the type identification of the corresponding configuration data of the configuration module, the mark of the configuration module or other identifier etc..

For aforesaid way (2) and (3), it whether there is the configuration module of configuration data exception on determining SDN controller Another example in, SDN controller can detect the configuration data that module is locally configured.For example, can be to configuration Phenomena such as loss of data, mistake or unloading, is detected.For example, when configuration item in the configuration data for detecting configuration module The case where (for example, l3vni or VPN) corresponding parameter is lost or configuration data is accidentally deleted or mistake unloading, determines the configuration Module is abnormal configuration module.

Any one of (1) to (3) in the above manner can determine that there are configuration data exceptions on SDN controller Configuration module can be restored using configuration recovery method provided by the invention, be realized with the network equipment in this case On original configuration data on the basis of configuration recovery process.In practical applications, if there are configuration datas on the network equipment It is abnormal, allocation data recovering can also be carried out on the basis of the configuration data on SDN controller.

In practical applications, exception can also occur in the network topology data of the network equipment on SDN controller.At this point, It can also include the following steps: before above-mentioned S210

If the network topology data of the network equipment occur abnormal on SDN controller, first to the network on SDN controller The network topology data of equipment are restored.

In above-mentioned steps, restoring to the network topology data on SDN controller can be by receiving user's triggering Network topology data are restored instruction and are restored.

For example, user can select to need to establish the network equipment of network topology by SDN controller, and trigger for choosing The network topology of the fixed network equipment restores instruction.For another example SDN controller can provide management network topology corresponding user Interface, the user interface can show the attachable network equipment；User is based on the user interface, and configuration needs to establish topology and closes The network equipment of system, such as configuration IP address, the username and password etc. of NETCONF connection；It is defeated that SDN controller receives user After the above-mentioned network topology for the network equipment entered restores instruction, NETCONF is established with the network equipment and is connect.

May exist relation of interdependence between above-mentioned each configuration module, if configuration data occur different for multiple configuration modules Often, then can be restored based on the relation of interdependence between this multiple abnormal configuration module, process configuration.

In some embodiments, abnormal configuration module may include multiple, and S230 can be real as follows at this time Existing: SDN controller can apply the original configuration data of multiple abnormal configuration modules.It is successively right according to preset configuration sequence Each abnormal configuration module carries out configuration recovery.

Wherein, above-mentioned preset configuration sequence includes: sequence of the configurations module prior to business configuration module, and The sequence of configuration dependence is deferred between different basic modules or between different business configuration module.

For example, above-mentioned preset configuration sequence can be first to configure virtual subnet, it is reconfigured virtual link layer network, so Virtual router is bound into virtual subnet afterwards, wherein virtual subnet is configured by virtual subnet configuration module, virtual link Layer network is configured by virtual link layer network configuration module, and virtual router binding virtual subnet is passed through virtual flow-line Device configuration module is realized；Virtual subnet configuration module, virtual link layer network configuration module and virtual router configuration module are all Belong to configurations module.When configuring recovery, virtual subnet configuration module is empty prior to virtual link layer network configuration module Intend link layer network configuration module prior to virtual router configuration module.

In addition, the above-mentioned original configuration data using multiple abnormal configuration modules, successively according to preset configuration sequence Configuration is carried out to each abnormal configuration module to restore at least to may include such as under type:

Example (1) can be by if abnormal configuration module is a part on SDN controller in all configuration modules The configuration module for selecting current exception from multiple abnormal configuration modules according to preset configuration sequence, matches using current abnormal It sets the corresponding original configuration data of module and generates the current abnormal corresponding original configuration item of configuration module and initial parameter；Using The corresponding original configuration item of the current abnormal configuration module and initial parameter configure current abnormal configuration module Restore.

Example (2) can be according to if abnormal configuration module is the whole on SDN controller in all configuration modules Preset configuration sequence selects the configuration module of current exception from multiple abnormal configuration modules, using current abnormal configuration The corresponding original configuration data of module generate the current abnormal corresponding original configuration item of configuration module and initial parameter；Using institute The corresponding original configuration item of some configuration modules and initial parameter, generate configuration data library file；Application configuration database file Configuration recovery is carried out according to preset configuration sequence.

In some embodiments, SDN controller, can be according to reception user's input when configuring to the network equipment Configuration data is configured.

For example, SDN controller can provide a kind of configuration module corresponding user configuration interface, user is based on user circle Face can input configuration item and the corresponding parameter of configuration item.SDN controller inputs configuration item and right according to the user that receives The parameter answered generates configuration order, and the command down-transmitting to the network equipment is realized to the configuration to the network equipment.

For another example SDN controller can provide virtual router configuration module corresponding user interface, the user interface packet Include configuration item VPN and configuration item l3vni, the corresponding typing domain of each configuration item, user can in the typing domain typing parameter, For example, in the corresponding typing domain typing 10002 of configuration item VPN, in the corresponding typing domain typing 10008 of configuration item l3vni.

Table 1

In addition, SDN controller can also generate data according to the corresponding relationship of the above-mentioned configuration item received and parameter Table, for example, the information based on above-mentioned typing, can be generated tables of data as shown in Table 1 above.The correspondence of the configuration item and parameter Relationship is typically stored in running memory, which is typically stored in local storage.Every kind of configuration module can correspond to Multiple tables of data can generate the configuration data of each configuration module, in this hair after SDN controller is restarted according to tables of data In bright embodiment, the configuration data in the corresponding local storage of abnormal configuration module and running memory is all abnormal, such as Data no exceptions in tables of data on fruit local storage, SDN controller can be directly according to the configurations in tables of data Data are restored.When restoring abnormal configuration module, the configuration module correspondence for needing to restore the exception is locally stored The configuration item and parameter in tables of data and running memory on device.

In above-mentioned example (1), it can be based on above-mentioned configuration process, when realizing that configuration restores, SDN controller can be only Configuration data in the corresponding tables of data of abnormal configuration module and running memory is restored.For example, original configuration data can be with For configuration order, the configuration order are as follows: the interface needed to configure is " vsi3 "；The configuration order is described as " SDN-VROUTE- vsi-10008"；" 10002 " are configured by IP-VPN；" 10008 " are set (alternatively, the interface needed to configure is by l3vni "VROUTE-vsi3").According to the configuration order, getting description is that SDN_VROUTE and configuration item vpn and l3vni are corresponding Configuration parameter, it is as shown in table 2 that configuration parameter data table can be generated with this.Virtual router can be configured based on the table 2 Module carries out configuration recovery.
