Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a computer-readable storage medium for scaling.
Background
In NS (Network Service), if scaling based on NS level is adopted, it is necessary to close the scaling at VNF (virtual Network Function) level to keep NS in a specified level and template.
In the prior art, when performing the scaling of the VNFs, a scaling strategy is determined for each VNF, and then the scaling is performed. In practical applications, on one hand, the VNF is usually deployed and operated for a certain period of time, and at this time, the VNF already has a mature auto-scaling rule. When it is incorporated into the NS, it is preferable to multiplex the scalability rules before the VNF. On the other hand, different VNFs included in the same NS generally have a certain association, which is directly embodied as an association of the scaling rule, that is, when traffic volume changes, multiple VNFs in the NS may have the same scaling requirement at the same time.
Thus, scaling VNFs is inefficient with prior art methods.

Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1, the method for expanding and reducing the volume of the embodiment of the present invention includes:
In practical applications, a group identification, such as groupId, may be added for each VNF in NSD (NS description file). The groupId value of each VNF may be set as needed, for example, set to 1,2,3, and the like.
And step 102, determining a target VNF with the group identifier in the NS according to the group identifier of the VNF to be scaled and shrunk.
Wherein the target VNF refers to a VNF having the same group identification as the VNF to be scaled. By reading the groupId values of the VNFs in the NS, the target VNF can be determined.
And 103, monitoring whether the target VNF triggers the capacity expansion and reduction operation.
In practical applications, it may be monitored at predetermined time intervals whether each target VNF triggers a scaling operation. Meanwhile, what type of capacity expansion and reduction operation is triggered by each target VNF can be monitored.
And 104, if it is monitored that the target VNF triggers a capacity expansion and reduction operation, triggering the VNF to be subjected to capacity expansion and reduction to execute the same capacity expansion and reduction operation as the target VNF.
If it is monitored that the target VNF triggers the capacity expansion and reduction operation, the capacity expansion and reduction strategy may be applied to the VNF to be subjected to capacity expansion and reduction according to the obtained capacity expansion and reduction strategy of the target VNF, so as to execute the same capacity expansion and reduction operation as the capacity expansion and reduction operation of the target VNF.
In the embodiment of the present invention, when it is required to perform capacity expansion on the VNF to be subjected to capacity expansion, if it is monitored that the target VNF having the same group identifier as the VNF to be subjected to capacity expansion triggers a capacity expansion and reduction operation, the same capacity expansion and reduction operation is performed on the VNF to be subjected to capacity expansion and reduction. Therefore, by using the scheme of the embodiment of the invention, the capacity expansion and reduction operation does not need to be executed after independently establishing the capacity expansion and reduction strategy for each VNF as in the prior art, thereby improving the efficiency of executing the capacity expansion and reduction operation on the VNF.
As shown in fig. 2, the method for expanding and reducing the volume according to the embodiment of the present invention includes:
For example, as shown in table 1, the group identifications set for the respective VNFs in the NS are as follows.
| SBC | PGW | TAS | HSS | MME | DNS | |
| Group identification | 1 | 1 | 1 | 2 | 2 | 0 |
TABLE 1
The method comprises the steps of adding a groupId parameter corresponding to each VNF in the NSD, and adding a groupSyncScaling switch in the NSD, so that the related expansion and contraction capacity can be opened aiming at a set group.
Wherein, the value in the groupsyncsscaling field indicates whether a certain VNF allows performing a capacity expansion and reduction operation of a certain VNF group (a group consisting of VNFs having the same group identification). For example, when the value is a first preset value, it may indicate that the capacity expansion and reduction operation is allowed to be performed; when the value is the second preset value, it can indicate that the capacity expansion and reduction operation is not allowed to be executed. The first preset value and the second preset value may be set arbitrarily, for example, the first preset value is Enable, and the second preset value is Disable. By this arrangement, flexibility of the capacity expansion and contraction operation is increased.
With the above settings, the NSD increase parameters are shown in table 2.
TABLE 2
The steps 201 and 202 are not executed in strict sequence.
And 204, determining a target VNF with the group identifier in the network service NS according to the group identifier of the VNF to be scaled and shrunk.
And step 205, monitoring whether the target VNF triggers the capacity expansion and reduction operation.
And step 206, determining whether the VNF to be subjected to capacity expansion and reduction allows the capacity expansion and reduction operation to be performed.
Specifically, in this step, the value of the group synchronization enabling group sync scaling field of the VNF to be scaled is obtained. If the value of the groupSyncScaling field is a first preset value, determining that the VNF to be subjected to capacity expansion and reduction allows the capacity expansion and reduction operation to be executed; and if the value of the groupSyncScaling field is a second preset value, determining that the VNF to be subjected to capacity expansion and reduction does not allow the capacity expansion and reduction operation to be executed.
Otherwise, the VNF to be subjected to capacity expansion and reduction is not triggered to execute the same capacity expansion and reduction operation as that of the target VNF.
For example, as shown in table 1 above, for example, the VNF to be expanded is HSS, the VNF in the same group as the VNF is PGW or SBC, and the value of the groupSyncScaling field of SBC or HSS is Enable. At a certain time, it is detected that the PGW triggers a certain capacity expansion and reduction operation, and then the capacity expansion and reduction operation can be executed to both the SBC and the HSS.
In the embodiment of the present invention, when it is required to perform capacity expansion on the VNF to be subjected to capacity expansion, if it is monitored that the target VNF having the same group identifier as the VNF to be subjected to capacity expansion triggers a capacity expansion and reduction operation, the same capacity expansion and reduction operation is performed on the VNF to be subjected to capacity expansion and reduction. Therefore, by using the scheme of the embodiment of the invention, the capacity expansion and reduction operation does not need to be executed after independently establishing the capacity expansion and reduction strategy for each VNF as in the prior art, thereby improving the efficiency of executing the capacity expansion and reduction operation on the VNF.

a determining module 305, configured to determine whether the VNF to be scaled and scaled allows performing a scaling operation; at this time, the triggering module 304 is specifically configured to, if it is monitored that the target VNF triggers a capacity expansion and reduction operation and the VNF to be subjected to capacity expansion and reduction allows the capacity expansion and reduction operation to be performed, trigger the VNF to be subjected to capacity expansion and reduction to perform a capacity expansion and reduction operation that is the same as the capacity expansion and reduction operation of the target VNF.
Wherein the determining module comprises: the obtaining submodule is used for obtaining the value of a group synchronization enabling field of the VNF to be subjected to expansion and contraction; the first determining submodule is used for determining that the VNF to be subjected to capacity expansion and reduction allows the capacity expansion and reduction operation to be executed if the value of the groupSyncScaling field is a first preset value; and the second determining submodule is used for determining that the VNF to be subjected to capacity expansion and reduction does not allow the capacity expansion and reduction operation to be executed if the value of the groupSyncScaling field is a second preset value.
As shown in fig. 5, in order to further improve the efficiency of the capacity expansion and reduction operation, the apparatus further includes:
a setting module 306, configured to set a group identifier for each VNF; and/or setting a value of a groupsyncsscaling field of each VNF.
