In order to guarantee the overall performance of system, when receiving a large amount of business, need to control service traffics, to keep away
The case where exempting from the reduction of business processing success rate, even resulting in system crash generation.
In NFV system, according to the priority of service message, service message is stored respectively to absolute priority list and
In relative priority list, which is used to store the service message of absolutely not flow control, as the centre of business disappears
Breath etc., the relative priority queue be used to store can flow control service message, such as the first message of business；System Priority processing should
Service message in absolute priority queue, if there is no service message to need to handle in the absolute priority queue, processing
Service message in relative priority queue.When the service message in the relative priority queue is excessive, and system resource can not
It when meeting concurrent processing a large number of services, needs to control service traffics, to guarantee that system can operate normally.
Specifically, the resource management module of VNF periodically acquires the side of the first resource occupancy of multiple first resource
Method, which can be divided into, to be directly acquired and two kinds of indirect gain.Wherein, directly acquiring method can be with are as follows: the resource management module of VNF connects
The first message that the NFVI layers of resource management module is sent is received, which includes at least the first of multiple first resource
Resources occupation rate；Indirect gain method refers to by establishing channel, the resource management of VNF between VNF, NFVI, VNFM and VIM
The first resource occupancy of NFVI layers of module indirect gain of multiple first resources, specifically includes following two method:
The first, the resource management module of VNF receive the second message that the VNF manager is sent, described second
Message is that the VIM that the VNF manager is obtained from the virtualized infrastructure manager VIM is periodical from the NFVI
The message that layer obtains, the second message include at least the first resource occupancy of the multiple first resource.It that is to say, it should
VIM periodically obtains the first resource occupancy of multiple first resource from NFVI layer, and VNFM is again from VIM acquisition multiple the
The first resource occupancy of one resource, and the first resource occupancy of multiple first resource is sent to the resource pipe of the VNF
Manage module.
Second, the resource management module of VNF periodically obtains the second message from the VNF manager, and described the
Two message are that the VIM that the VNF manager is obtained from the virtualized infrastructure manager VIM is periodical from described
The message of NFVI layers of acquisition, the second message include at least the first resource occupancy of the multiple first resource.It that is to say,
The VIM periodically obtains the first resource occupancy of multiple first resource from NFVI layers, and VNFM obtains from the VIM multiple again
The first resource occupancy of first resource, the resource management module of the VNF obtain the of multiple first resource from the VNFM again
One resources occupation rate.
It should be noted that the second quantity of the first quantity and multiple Secondary resource for multiple first resource,
First quantity can be 1, or maximum resource number possessed by being less than or equal to NFVI layers greater than 1, the embodiment of the present invention
This is not construed as limiting, similarly, the embodiment of the present invention is also not especially limited second quantity.
In the present embodiment, only with obtained simultaneously according to same period the first resource first resource occupancy and this
For the Secondary resource occupancy of two resources, job flow control method provided by the present invention is illustrated；In fact, obtaining
The period for taking the period of the first resource occupancy of the first resource and obtaining the Secondary resource occupancy of the Secondary resource can be with
It is identical, it can also be different, furthermore, it is possible to obtain the first resource occupancy of the first resource and the resource of the Secondary resource simultaneously
Occupancy can also obtain the first resource occupancy of the first resource in different time respectively and the resource of the Secondary resource accounts for
With rate, the embodiment of the present invention is not construed as limiting this.
By establishing channel between VNF, NFVI, VNFM and VIM, so that VNF obtains NFVI layers of resources occupation rate, with
It can be real according to the resources occupation rate of multiple Secondary resources of the resources occupation rate and application layer of NFVI layers of multiple first resources
Existing service traffics control.
202, the resource management module of VNF is by the first resource occupancy of multiple first resource and multiple Secondary resource
Secondary resource occupancy store into burdened resource management list.
The content stored in the burdened resource management list includes at least multiple first resource and multiple second money
The identification information of every kind of resource, resources occupation rate and flow control threshold value in source.The identification information of the resource is corresponding for unique identification
Resource, the flow control threshold value are somebody's turn to do as the measurement standard for judging whether resource overloads if the resources occupation rate of any resource is greater than
The flow control threshold value of resource, it is determined that the resource overload needs to control service traffics at this time, in order to avoid influence business processing at
Power.It should be noted that other can also be stored in the burdened resource management list with multiple first resource and this is more
The relevant information of a Secondary resource, the present invention is not especially limit this.
For example, when the flow control threshold value of any first resource is 80%, if the first resource occupancy of the first resource
Greater than 80%, it is determined that first resource overload.It certainly, can also include other information in the burdened resource management list, this
Inventive embodiments are not construed as limiting this.
203, when there are the resources occupation rates of at least one resource to reach in multiple first resource and multiple Secondary resource
When to corresponding flow control threshold value, the business flow control module of VNF according to the resources occupation rate of at least one resource, calculate this at least one
Every kind of resource is corresponding in kind resource puts the literary number of notification.
This is put the literary number of notification and refers to that resource is capable of the traffic peak of concurrent processing, and every kind of resource, which has, corresponding puts notification
The literary number of notification of putting of literary number, different resource may be the same or different, and the embodiment of the present invention is not construed as limiting this.
The corresponding method for putting the literary number of notification of the resource is calculated according to the resources occupation rate for any resource for reaching flow control threshold value
It can be with are as follows: according to the resources occupation rate of preset ratio and the resource, calculate and corresponding puts the literary number of notification；For example, if the resource
It is 10000 that correspondence system default, which puts the literary number of notification, when resources occupation rate is not up to flow control threshold value, which is 80%, the money
Every to increase by 5% after the resources occupation rate in source reaches the flow control threshold value, it is 20% reduction that this, which puts the literary number of notification by preset ratio, with
Reduce system burden；Wherein, which may be other numerical value, and the embodiment of the present invention is not construed as limiting this.Certainly,
This can be calculated using other methods and puts the literary number of notification, and the embodiment of the present invention is also not construed as limiting this.
204, the business flow control module of VNF puts the literary number of notification, control according to every kind of resource in at least one resource is corresponding
Business clearance amount processed.
Select any resource is corresponding to put notification from corresponding put in the literary number of notification of every kind of resource in at least one resource
Literary number puts the literary number of notification as target, controls business clearance amount；Also it can choose and put by what step 203 calculating obtained at first
It is notified to literary number as target and puts the literary number of notification, controls business clearance amount, the embodiment of the present invention is not construed as limiting this.
In an alternative embodiment of the invention, the literary number of notification, control are put according to every kind of resource in at least one resource is corresponding
Business clearance amount processed can be with are as follows: puts the literary number of notification according to every kind of resource in at least one resource is corresponding, it is logical to determine that target is put
Message number；The literary number of notification is put according to the target, controls business clearance amount.
Specifically, the literary number of notification is put according to every kind of resource in at least one resource is corresponding, determines that target puts notification text
Number includes: to put in the literary number of notification from every kind of resource in at least one resource is corresponding, determines that minimum puts the literary number of notification；Most by this
It is small put the literary number of notification and be determined as the target put the literary number of notification.It that is to say, when in multiple first resource and multiple Secondary resource
When only existing the resources occupation rate of resource a kind of and reaching corresponding flow control threshold value, the literary number of notification of putting of the resource is determined as target report
Literary number, when there are the resources occupation rates of at least two resources to reach corresponding stream in multiple first resource and multiple Secondary resource
When controlling threshold value, the corresponding minimum being notified in literary number of putting of at least two resource is put into the literary number of notification, is determined as target and puts notification
Literary number.
By the way that when the resources occupation rate there are many resource reaches flow control threshold value, corresponding put of the multiple resources is notified to text
Minimum in number puts the literary number of notification and is determined as object message number, controls business clearance amount, can utmostly guarantee system performance
Stability, avoid the case where system crash is led to due to resource heavy overload.
By putting the literary number of notification according to the target, business clearance amount is controlled, can be realized according to Current resource occupancy,
On the basis of making full use of resource, processing business message as much as possible had not only guaranteed the success rate and efficiency of business processing, but also not
The overall performance of system is impacted.For example, putting the literary number of notification is when the resources occupation rate of a certain resource is 85%
10000；When the resources occupation rate of the resource is 90%, putting the literary number of notification is 5000；When the resources occupation rate of the resource
When being 95%, putting the literary number of notification is 1000.It that is to say, when resources occupation rate is higher, it is fewer to put the literary number of notification accordingly, to keep away
Exempt to cause bigger system burden, influences the overall performance of system.
By periodically acquire NFVI layers of multiple first resources first resource occupancy and application layer multiple second
The resources occupation rate of resource, according to reaching at least the one of corresponding flow control threshold value in multiple first resource and multiple Secondary resource
The resources occupation rate of kind resource calculates corresponding put of at least one resource and is notified to literary number, and according at least one resource pair
That answers puts the literary number of notification, controls business clearance amount, can be simultaneously according to NFVI layers and the occupation condition of application layer, to business
Flow is controlled, and is avoided the occurrence of when application layer resource is not overloaded and NFVI layers of resource overload, due to can not be to Business Stream
The problem of amount control effectively, and business processing success rate is caused to reduce；Further, by VNF, NFVI, VNFM and VIM
Between establish channel so that VNF obtains NFVI layers of resources occupation rate, with can be according to the money of NFVI layers of multiple first resources
The resources occupation rate of multiple Secondary resources of source occupancy and application layer realizes service traffics control.
