Much it is different from other way described herein to implement, those skilled in the art can be without prejudice to intension of the present invention the case where
Under do similar popularization, therefore the present invention is not limited to the specific embodiments disclosed below.
Before introducing embodiment, first to this application involves relational language explain.
SDN:(Software Defined Networking, software defined network) is a kind of Novel net of Emulex network

Controller：The control unit interacted with network element, single or multiple controller composition control planes；
ODL:(Open Day Light), a kind of Open Framework that network controller is realized.
After describing relational language, the introduction of the embodiment of the present application is carried out.The application first embodiment provides one
Kind SDN network controller bay construction system.Referring to FIG. 2, it illustrates a kind of SDN network controls that the application first embodiment provides
The schematic diagram of device architecture system processed.Wherein, the SDN network controller bay construction system includes：Data memory module 201, change
Configuration module 202 corrects configuration module 203, southbound interface module 204.
The data memory module 201, the requirement configuration parameter sent for storing the change configuration module；
The change configuration module 202, for issuing the requirement configuration parameter of network element to network element and configuring the requirement
Parameter is stored to data memory module；
The correction configuration module 203, for correcting the actual configuration parameter of the network element；
The southbound interface module 204, for realizing the number between change configuration module and correction parameter module and network element
According to interaction.
The SDN network controller bay construction system can be used to realize that the application second embodiment provides a kind of SDN net
The method that network element configuration parameter is corrected in network, the method is mainly by the correction configuration module in SDN network controller bay construction system
203 realize.Correction network element in the application SDN network is discussed in detail below in conjunction with the SDN network controller bay construction system to match
The method for setting parameter.
The application second embodiment provides a kind of method that network element configuration parameter is corrected in SDN network.Referring to FIG. 3,
It illustrates the flow charts for the method that network element configuration parameter is corrected in a kind of SDN network provided according to an embodiment of the present application.
It is described in detail below in conjunction with Fig. 2 and Fig. 3.This method is introduced in order to clearer simultaneously, during illustrating this method,
It is introduced in combination with two specific examples.
Example 1, as shown in figure 4, the current topology that is made of by one 5 network elements of A, B, C, D, E, have business need from A to
E, controller have found a paths A->D->C->E, controller needs the configuration distributing by path into network element, wherein updating D
When node configures, configuration failure is updated, but the message of D node notification controller failure is lost in transmission process, D node
Configuration do not come into force, therefore D->The path of C is abnormal, but controller does not know update failure.
Example 2, as shown in figure 5, in the topology being made of 5 network elements of A, B, C, D, E, remained on D node and be forwarded to C's
Configuration currently has business to need from A to E, and controller finds out path A->D->E is issued and is configured to A, D, E node, if D node
The remaining configuration preference level for being forwarded to C node than newly issue be forwarded to E node configuration it is high, the path of last practical efficiency is
A->D->C, it is final without arriving E.
Step S301, locks network element.
The network element refers to network element to be corrected.
During being corrected to network element configuration parameter, in order to guarantee that the configuration parameter of network element is not modified, by institute
It states network element and is set as lock state, i.e. the write-protect state of network element.
After setting lock state for the network element, controller can be just to the modification of the configuration parameter of the network element
Often execute；When pending if there is the task of the configuration parameter of other clients modification network element, since network element has been in write-protect shape
State, therefore cannot be immediately performed, it needs first for the configuration task to be cached to the corresponding task queue of the network element, wait to be locked
After state becomes open state, then execute the pending task.If there is reading the task of configuration parameter in network element, Ke Yizheng
Often execute.
In the specific implementation, network element is locked, can controller set network element parameter state value by way of, if
Lock is determined when parameter state value StateValue corresponding to network element is 1 to be lock state, and state value StateValue is when being 0
Network element state value StateValue is set as 1, is then locked to network element by open state, controller.
In example 1 and example 2, network element is locked, exactly node D network element is locked, when it is implemented, controller
Parameter state value StateValue corresponding to node D network element can be set as 1.
Step S302, judge the network element actual configuration parameter and the currently stored network element requirement configuration parameter it
Between it is whether identical, if it is not, execute step S303, if so, execute step S304.
The network element actual configuration parameter is often referred to configuration parameter when network element operation, may be with controller to network element
Configuration parameter is consistent, it is also possible to which change causes it inconsistent with the configuration parameter of controller requirement network element at runtime.
The requirement configuration parameter of the network element is often referred to the requirement configuration parameter that controller is handed down to network element.In example 1,
The requirement configuration parameter that controller is handed down to D node network element includes being forwarded to the configuration of C, and in example 2, controller is handed down to D node
The requirement configuration parameter of network element includes being forwarded to the configuration of E.
The requirement configuration parameter of the currently stored network element is often referred to controller and is handed down to mandate configuration ginseng
Number, network element actual parameter are stored in the requirement of the network element in configuration database after configuration parameter is updated successfully as requested
Configuration parameter.
In SDN network, since its actual configuration parameter often changes network element at runtime, lead to the reality of network element
There is inconsistent situation in the requirement configuration parameter of border configuration parameter and the currently stored network element, in order to keep controller with
Network element configuration parameter is consistent, and controller needs the task of start-up check network element configuration parameter, is corrected to network element configuration parameter,
It is corrected and is mainly realized by the correction configuration module 203 in Fig. 2.
The step S301 is being executed, i.e., after controller locks network element to be corrected, correction configuration module 203 is just
Can carry out correcting for network element configuration parameter, first determine whether the currently stored network element requirement configuration parameter and the net
Whether first actual configuration parameter is identical, if the two is different, illustrates that above-mentioned two configuration parameter is inconsistent, executes step
S303 realizes that two configuration parameters are consistent, completes correction, if the two is identical, without correction, is directly entered step S304.
It is between the judgement network element actual configuration parameter and the requirement configuration parameter of the currently stored network element
It is no identical, including：
Obtain the actual configuration parameter of the network element；
Obtain the requirement configuration parameter of the currently stored network element；
The requirement configuration parameter of the actual configuration parameter of the network element and the currently stored network element is carried out pair
Than if it is different, the then requirement configuration parameter of the actual configuration parameter of the judgement network element and the currently stored network element
Between whether identical judging result is no.
Fig. 6 is referred to, for the judgement network element actual configuration parameter that provides of first embodiment of the application and current
Storage the network element requirement configuration parameter between whether identical flow chart, specifically include step S302-1 to S302-3.
Step S302-1 obtains the actual configuration parameter of the network element.
The actual configuration parameter of network element can be obtained by Openflow agreement by correcting configuration module 203.When it is implemented,
Correction data module 203 can be sent to network element to be corrected by southbound interface module 204 and obtain the network element actual disposition
Its actual configuration parameter is returned to correction data module, the two by southbound interface module 204 by the order of parameter, the network element
Interactive process uses Openflow agreement.For example, the actual disposition ginseng of D node network element is obtained in example 2 by Openflow agreement
Number is including being forwarded to the configuration of C and being forwarded to the configuration of E.
OpenFlow agreement is the interface standard for describing the information that interaction is used between controller and network element, core
It is the set of OpenFlow protocol information.OpenFlow agreement supports three kinds of type of messages：controller-to-switch,
Asynchronous (asynchronous) and symmetric (symmetrical), and every a kind of message can possess multiple sub- type of messages.Its
In, controller-to-switch message is initiated by controller, for managing or obtaining the network element for supporting OpenFlow agreement
The state of (referring mainly to OpenFlow interchanger)；Asynchronous message is used by supporting the network element of OpenFlow agreement to initiate
Network event or network element state variation are updated and arrive controller；Symmetric message can be initiated by interchanger or controller.
Step S302-2 obtains the requirement configuration parameter of the currently stored network element.
Correction configuration module 203 can (data memory module can be designed as configuring by reading data memory module 201
Database) storage presently described network element configuration data come obtain the currently stored network element requirement configuration ginseng
Number.For example, correcting configuration module in example 1 to obtain the requirement configuration parameter of the currently stored D node network element includes being forwarded to C
Configuration, it includes being forwarded to E that correction configuration module, which obtains the requirement configuration parameter of the currently stored D node network element, in example 2
Configuration.
It should be noted that step S302-1 and the sequence of step S302-2 are unrestricted, sequence be can be interchanged.
Step S302-3 configures the requirement of the actual configuration parameter of the network element and the currently stored network element
Parameter compares, if it is different, then the actual configuration parameter of the judgement network element and the currently stored network element are wanted
Ask between configuration parameter whether identical judging result is no.
Wanting for network element actual configuration parameter and the currently stored network element is obtained respectively in correction configuration module 203
After seeking configuration parameter, the two is compared, if comparing result is that the two is not identical, the reality of the judgement network element is matched
Set between parameter and the requirement configuration parameter of the currently stored network element whether identical judging result is no.
In example 2, the actual configuration parameter for obtaining D node network element includes the configuration for being forwarded to C and the configuration for being forwarded to E, is obtained
The requirement configuration parameter for taking the currently stored D node network element includes being forwarded to the configuration of E, and by comparison, both discoveries are no
Together, then judge between the actual configuration parameter of D node network element and the requirement configuration parameter of currently stored D node network element whether phase
Same judging result is no.
Step S303 corrects the network element using the requirement configuration parameter of the currently stored network element as foundation
Actual configuration parameter.
If judging the requirement configuration of the network element actual configuration parameter and the currently stored network element in step S302
It is not identical between parameter, then it needs to correct the net using the requirement configuration parameter of the currently stored network element as foundation
The actual configuration parameter of the network element, i.e., is changed to the requirement of the currently stored network element by the actual configuration parameter of member
Configuration parameter.
Situation is included the following three types when correcting the actual configuration parameter of the network element：Wherein the first situation is：Work as net
When requirement configuration parameter in the actual configuration parameter of member relative to the currently stored network element has extra configuration, delete
Except configuration extra described in the network element；Second situation is：When in the actual configuration parameter of network element relative to described current
When the requirement configuration parameter of the network element of storage has the configuration of loss, the configuration of the loss is re-write into the network element
In；The third situation is：When the requirement of the numerical value and the currently stored network element of the actual configuration parameter of network element configures
In parameter when the numerical value difference of same parameters, modified in the actual configuration parameter using the parameter values required in configuration parameter
Same parameters numerical value.
For the first situation by taking example 2 as an example, the actual configuration parameter that correction configuration module obtains D node network element includes being forwarded to
The configuration of E and the configuration for being forwarded to C, the requirement configuration parameter for obtaining the currently stored D node network element includes being forwarded to E's
Configuration finds that the requirement of the corresponding currently stored network element in D node network element actual configuration parameter is matched by comparison
Setting parameter has the extra configuration for being forwarded to C, then controller deletes the configuration for being forwarded to C extra in the network element, completes school
Just.
For second situation by taking example 1 as an example, correction configuration module obtains the actual configuration parameter of D node network element and currently stored
The requirement configuration parameter of D node network element found corresponding described current in D node network element actual configuration parameter by comparison
The requirement configuration parameter of the network element of storage has the configuration for being forwarded to C of loss, then controller will be forwarded to the configuration of C again
It is written in D node network element, the requirement of D node network element actual configuration parameter and the currently stored network element at this time, which configures, to be joined
Number has reached consistent, completes correction.
For example, the third situation, the value of a in the requirement configuration parameter of the currently stored network element is 1, network element
The value of actual configuration parameter a is 2, then the value of network element actual configuration parameter a is revised as 1.
By correction, the requirement configuration parameter of network element actual configuration parameter Yu the currently stored network element ensure that
Unanimously, business runs well, and improves system reliability.
Step S204 releases the locking to the network element.
After having corrected the configuration parameter of network element, need to release the locking to the network element, so as to by network element
New requirement configurable write enters network element.
The locking to the network element is released, i.e., the network element is set on state, setup parameter value can be passed through
Mode, such as set state value StateValue as 0, then relieve the locking to the network element.
In example 1 and example 2, the locking to the network element is released, i.e., node D network element is set on state, it is specific real
Parameter state value StateValue corresponding to node D network element can be set as 0 by Shi Shi, controller.
After the step of releasing the locking to the network element, require to look up whether the corresponding task queue of the network element deposits
In pending configuration task；If it exists, it executes the pending configuration task and updates network element actual configuration parameter；Then right
The requirement configuration parameter of the currently stored network element is updated, keep the actual configuration parameter of network element with it is currently stored
The network element requirement configuration parameter it is consistent.
It, can be in order to guarantee that network element actual configuration parameter is consistent with the requirement configuration parameter of the currently stored network element
Start by set date corrects the task of element configuration data, and timing carries out the correction of element configuration data, to avoid network element actual disposition
Parameter and the requirement configuration parameter of the currently stored network element are inconsistent, and then generation the case where lead to service disconnection.It can be with
A very short time interval is set by the period of timing, for example, 1 minute.
So far, the method that network element configuration parameter is corrected in SDN network provided by the embodiments of the present application has been carried out specifically
It is bright.The application joins by comparing the time configuration of the mandate configuration parameter and the network element that store in configuration database
Number whether there is difference, if so, the network element time configuration parameter to be changed to the net stored in the configuration database
Member requires configuration parameter, completes the configuration correction to network element, by correcting controller delete in network element extra configuration or
The configuration of loss is re-write, has repaired the configuration error of network element in time, the actual configuration parameter and controller for making network element are to net
Member requires configuration parameter to maintain unanimously, avoids service disconnection, ensure that business operates normally.
