Among them, the network slicing technique is one of the greatest advantages of the 5G technique over the 4G technique.

The virtual resource management method and the virtual resource management device provided by the invention are used for solving the performance compatibility problem existing when virtual network function resources with different performance indexes are integrated, providing a method for calculating the performance compatibility of virtual network function resource combination, and matching corresponding virtual network function resource combination for a network slice based on the performance compatibility of the virtual network function resource combination and the service level requirement of the network slice, thereby ensuring the service quality provided by the network slice.
Fig. 1 is a flowchart of a virtual resource management method provided in this embodiment. As shown in fig. 1, the virtual resource management method may include the following steps:
step S101, according to the performance parameters of the virtual network function resources, calculating the performance compatibility of the virtual network function resource combination corresponding to the service function.
A Virtual Network Function (VNF) is a Network Function based on a software form, and belongs to an important component of Network Function Virtualization (NFV), and the VNF can decouple the Network Function from a dedicated hardware device, thereby improving flexibility and extensibility of a Network. The VNF resource is a resource corresponding to the VNF, and the VNF resource combination is composed of one or more VNF resources. The service function corresponds to one or more VNF resource combinations, and each VNF resource combination can support the implementation of the service function.
The performance parameters of the VNF resources are parameters that may reflect performance characteristics of the VNF resources, including but not limited to provider identification, service success rate, reliability, processing overhead, and processing latency. The performance compatibility of the VNF resource combination is a parameter for measuring the performance compatibility of the VNF resource combination, and is related to the performance parameters of the VNF resources that constitute the VNF resource combination. Wherein the performance parameter of the VNF resource may be obtained from registration information of the VNF resource.
According to the performance parameters of the VNF resources, the step of calculating the performance compatibility of the VNF resource combination corresponding to the service function comprises the following steps:
firstly, determining all VNF resource combinations corresponding to service functions;
secondly, calculating the performance component of the VNF resource combination according to the performance parameters of all VNF resources in the VNF resource combination, wherein the performance component comprises but is not limited to a supplier attribute, a service success rate, reliability, processing overhead and processing time delay;
thirdly, calculating the performance compatibility of the VNF resource combination based on the performance component of the VNF resource combination;
and finally, calculating the performance compatibility of all VNF resource combinations corresponding to the service function by adopting the same method.
In one embodiment, it is assumed that a certain service function corresponds to two VNF resource combinations, and the performance components of the VNF resource combinations include provider attributes, service success rates, reliability, processing overhead, and processing latency.
First, the performance components of the first VNF resource combination are calculated. The method comprises the following specific steps:
calculating the supplier attributes of the VNF resource combination according to the supplier identifications of all VNF resources in the VNF resource combination;
calculating the service success rate of the VNF resource combination according to the service success rates of all VNF resources in the VNF resource combination;
calculating the reliability of the VNF resource combination according to the reliability of all VNF resources in the VNF resource combination;
calculating the processing cost of the VNF resource combination according to the processing cost of all VNF resources in the VNF resource combination;
and calculating the processing time delay of the VNF resource combination according to the processing time delays of all the VNF resources in the VNF resource combination.
And secondly, calculating the performance compatibility of the first VNF resource combination according to the calculated performance component of the first VNF resource combination. The specific content comprises the following steps:
and calculating the performance compatibility of the VNF resource combination based on the supplier attribute, the service success rate, the reliability, the processing overhead and the processing time delay of the VNF resource combination.
And finally, calculating the performance compatibility of the second VNF resource combination corresponding to the service function by adopting the same method, thereby obtaining the performance compatibility of all VNF resource combinations corresponding to the service function.
For example, the service function is document retrieval, and the function types supporting the document retrieval include an input function, a search engine function, and a result presentation function, so that the function types of the VNF resource corresponding to the document retrieval also include the input function, the search engine function, and the result presentation function.
It is assumed that the performance parameters of the VNF resources are as shown in table 1.
TABLE 1
VNF resources VNF1 VNF2 VNF3 VNF4
Type of function Input device Input device Search engine Results display
Supplier identification sup1 sup1 sup2 sup1
Success rate of service 60％ 80％ 70％ 50％
Reliability of 0.8 0.7 0.5 0.6
Processing overhead 0.1 0.15 0.3 0.2
Processing time delay 0.2 0.3 0.5 0.1
As can be seen from table 1, there are two VNF resource combinations corresponding to the document retrieval service, where the first VNF resource combination includes VNF1, VNF3, and VNF4, and the second VNF resource combination includes VNF2, VNF3, and VNF 4.
First, the performance components of the first VNF resource combination are calculated. The method specifically comprises the following steps:
step 1: vendor attributes for the first VNF resource combination are computed from vendor identifications of VNF1, VNF3, and VNF 4.
Since the vendor of VNF1 and VNF4 is identified as sup1 and the vendor of VNF3 is identified as sup2, i.e. the maximum number of VNF resources identified by the vendor in the first VNF resource combination is 2(VNF1 and VNF4), therefore:
M1＝n1/N1
＝2/3
wherein M1 is a first VNSupplier attribute of F resource combination, n1Identifying a maximum number of identical VNF resources, N, for a provider in a first VNF resource combination1Is the number of VNF resources in the first VNF resource combination.
Step 2: and calculating the service success rate of the first VNF resource combination according to the service success rates of the VNF1, the VNF3 and the VNF 4.

Figure BDA0002291780090000091
Wherein, S1 is a service success rate of the first VNF resource combination, SiFor the service success rate of each VNF resource in the first VNF resource combination, i is the sequence number of the VNF resource in the first VNF resource combination, and the value of i in this example is 1, 2, and 3, respectively.
And step 3: the reliability of the first VNF resource combination is calculated from the reliabilities of VNF1, VNF3, and VNF 4.
Figure BDA0002291780090000092
Where R1 is the reliability of the first VNF resource combination, RiFor the reliability of each VNF resource in the first VNF resource combination, i is the sequence number of the VNF resource in the first VNF resource combination, and the value of i in this example is 1, 2, and 3, respectively.
The VNF resource has a sequence number, and in this example i takes on values of 1, 2 and 3, respectively.
And 4, step 4: the processing overhead of the first VNF resource combination is calculated from the processing overhead of VNF1, VNF3, and VNF 4.
Figure BDA0002291780090000093
Where E1 is the processing overhead of the first VNF resource combination, EiFor a first type of VNF resourceThe processing overhead of each VNF resource in the combination, i, is the sequence number of the VNF resource in the first VNF resource combination, and in this example, the value of i is 1, 2, and 3, respectively.
And 5: processing latency of the first VNF resource combination is calculated from processing latency of VNF1, VNF3, and VNF 4.
Figure BDA0002291780090000094
Wherein D1 is the processing delay of the first VNF resource combination, DiFor the processing delay of each VNF resource in the first VNF resource combination, i is the sequence number of the VNF resource in the first VNF resource combination, and the value of i in this example is 1, 2, and 3, respectively.
And secondly, calculating the performance compatibility of the first VNF resource combination according to the calculated performance component of the first VNF resource combination.
Specifically, the performance compatibility of the VNF resource combination is calculated based on the vendor attribute, the service success rate, the reliability, the processing overhead, and the processing delay of the VNF resource combination.
Assuming that the performance compatibility calculation function is f, the performance compatibility of the first VNF resource combination can be calculated by the following formula:
C1＝f(M1，S1，R1，E1，D1)
where C1 is the performance compatibility of the first VNF resource combination.
Finally, the same method is adopted to calculate the performance compatibility of the second VNF resource combination, and the following can be obtained:
C2＝f(M2，S2，R2，E2，D2)
where C2 is performance compatibility of the second VNF resource combination, M2 is a vendor attribute of the second VNF resource combination, S2 is a service success rate of the second VNF resource combination, R2 is reliability of the second VNF resource combination, E2 is processing overhead of the second VNF resource combination, and D2 is processing latency of the second VNF resource combination.
According to the steps, the performance compatibility of all VNF resource combinations corresponding to the literature retrieval is obtained.
It should be noted that, before calculating the performance compatibility of all VNF resource combinations corresponding to the service function according to the performance parameters of the VNF resources, the method further includes the following steps:
receiving registration information of the VNF resources, wherein the registration information comprises function types and performance parameters of the VNF resources;
and combining the VNF resources with the registered VNF resources according to the service functions and the function types of the VNF resources to form a VNF resource combination corresponding to the service functions.
For example, the function types supporting a certain service function include function type 1, function type 2, and function type 3.
It is assumed that the registered VNF resources include VNF1, VNF2, VNF3, and VNF4, and the function types of these VNF resources are as shown in table 2.
TABLE 2
Type of function Function type 1 Function type 2 Function type 3
VNF resources VNF1、VNF2 VNF3 VNF4
In the current state, the VNF resource combinations corresponding to the service functions include two types, the first VNF resource combination includes VNF1, VNF3, and VNF4, and the second VNF resource combination includes VNF2, VNF3, and VNF 4.
Assuming that registration information of the VNF5 is received, the function type and the performance Parameter (Parameter) of the VNF5, i.e., the function type 3 and the performance Parameter set (Parameter), respectively, are known from the registration information.
Since VNF5 corresponds to function type 3, combining VNF5 with registered VNF1, VNF2, VNF3, and VNF4, a new VNF resource combination corresponding to the service function can be obtained, which is: VNF1, VNF3, and VNF 5; VNF2, VNF3, and VNF 5.
At this time, all VNF resources corresponding to the service function are combined into four types, which are:
first VNF resource combination: VNF1, VNF3, and VNF 4;
a second VNF resource combination: VNF2, VNF3, and VNF 4;
a third VNF resource combination: VNF1, VNF3, and VNF 5;
a fourth VNF resource combination: VNF2, VNF3, and VNF 5.
It should be noted that after receiving the registration information of the VNF resource, the virtual resource manager needs to verify the validity of the registration information of the VNF resource. And if the validity of the registration information passes the verification, the virtual resource manager sends a notification for submitting the VNF resource to the administrator. And after receiving the notification of submitting the VNF resources, the administrator submits the corresponding VNF resources. The virtual resource manager receives the VNF resources submitted by the administrator, and further verifies the validity of the submitted VNF resources. And if the submitted VNF resource passes the validity verification, registering the VNF resource and storing the VNF resource to a corresponding position. The virtual resource manager is an abstract entity that implements the virtual resource management function, and may be software and/or hardware and/or a combination of software and hardware.
Step S102, establishing a mapping relation between the performance compatibility of the virtual network function resource combination and the service level of the service function.
The service level may reflect a quality level of the service provided by the service function. The higher the service level, the higher the quality level of the service provided by the service function, and the lower the service level, the lower the quality level of the service provided by the service function. The service level is related to many factors, where performance compatibility of the VNF resource combination corresponding to the service function is one of important factors affecting the service level, that is, there is a mapping relationship between the service level and the performance compatibility of the VNF resource combination. Generally, the higher the service level, the higher the performance compatibility requirement, and conversely, the lower the service level, the lower the performance compatibility requirement. In a specific use process, the mapping relationship between the service level and the performance compatibility of the VNF resource combination may be set according to actual business requirements.
For example, assume that the service classes of the service function include class i, class ii, class iii, and class iv, where class i represents the class of service with the highest quality of service level and class iv represents the class of service with the lowest quality of service level. The performance compatibility of the VNF resource combination corresponding to the service function includes six values, 1, 2, 3, 4, 5, and 6, where the performance compatibility of the VNF resource combination is relatively best when the performance compatibility is 6, and correspondingly, the performance compatibility of the VNF resource combination is relatively worst when the performance compatibility is 1. Based on the principle that the higher the service level is, the higher the requirement on the performance compatibility of the VNF resource combination is, and in combination with the actual service requirement, a mapping relationship between the performance compatibility of the VNF resource combination and the service level of the service function is established as shown in table 3.
TABLE 3
Service class Performance compatibility of VNF resource combinations
Class I 6
Stage II 5
Class III 3 and 4
IV stage 1 and 2
Step S103, a list of service functions, service levels, virtual network function resource combination performance compatibility and virtual network function resource combinations is established based on the mapping relationship between the performance compatibility of the virtual network function resource combinations and the service levels of the service functions.
Since there is a corresponding relationship between the service function and the service level, and there is a corresponding relationship between the VNF resource combination and the VNF resource combination performance compatibility, based on the mapping relationship between the performance compatibility of the VNF resource combination and the service level of the service function established in step S102, a list of the service function, the service level, the VNF resource combination performance compatibility, and the VNF resource combination may be established.
For example, the service classes corresponding to the query service function include class i, class ii, class iii, and class iv, the query service function corresponds to 8 VNF resource combinations, which are a first VNF resource combination, a second VNF resource combination, a third VNF resource combination, a fourth VNF resource combination, a fifth VNF resource combination, a sixth VNF resource combination, a seventh VNF resource combination, and an eighth VNF resource combination, and the performance compatibility values of the respective corresponding VNF resource combinations are 6, 3, 4, 5, 2, 1, and 5.
It is assumed that the mapping relationship between the service level of the query service function and the performance compatibility of the VNF resource combination established in step S102 is shown in table 4.
TABLE 4
Service class Performance of VNF resource combinationsCompatibility
Class I 6
Stage II 5
Class III 3 and 4
IV stage 1 and 2
In summary, a list of service functions, service classes, VNF resource combination performance compatibility and VNF resource combinations may be established, as shown in table 5.
TABLE 5
Figure BDA0002291780090000131
As can be seen from table 5, the VNF resource combination that can provide the level i query service is the first VNF resource combination; the VNF resource combination that can provide the level ii query service is a fifth VNF resource combination and an eighth VNF resource combination; the VNF resource combination that can provide the level-iii query service is a second VNF resource combination, a third VNF resource combination, and a fourth VNF resource combination; the VNF resource combinations that may provide iv-level query services are a sixth VNF resource combination and a seventh VNF resource combination.
Step S104, providing service based on the list.
Providing services based on the list refers to matching corresponding VNF resource combinations for the network slice based on the list of service function, service level, virtual network function resource combination performance compatibility and virtual network function resource combinations established in step S103 according to the service function requirements and service level requirements of the network slice, and providing services for the service requirements of the network slice based on the matched VNF resource combinations.
In one embodiment, providing a service based on a list comprises the steps of:
firstly, receiving a service requirement sent by a network slice;
secondly, responding and analyzing the service requirement of the network slice, and acquiring the service function requirement and the service level requirement of the network slice from the analyzed service requirement;
thirdly, according to the service function requirements and the service level requirements of the network slice, matching the VNF resource combinations which can meet the service function requirements and the service level requirements of the network slice based on the list of the service function, the service level, the VNF resource combination performance compatibility and the VNF resource combinations established in step S103;
and finally, arranging VNF resources in the VNF resource combination according to the service functions and the service providing modes of the network slice, wherein the VNF resources provide corresponding functions according to the arrangement sequence, thereby providing services for the service requirements of the network slice.

The calculating module 210 is configured to calculate performance compatibility of a virtual network function resource combination corresponding to the service function according to the performance parameter of the virtual network function resource.
A Virtual Network Function (VNF) is a Network Function based on a software form, and belongs to an important component of Network Function Virtualization (NFV), and the VNF can decouple the Network Function from a dedicated hardware device, thereby improving flexibility and extensibility of a Network. The VNF resource is a resource corresponding to the VNF, and the VNF resource combination is composed of one or more VNF resources. The service function corresponds to one or more VNF resource combinations, and each VNF resource combination can support the implementation of the service function.
The performance parameters of the VNF resources are parameters that may reflect performance characteristics of the VNF resources, including but not limited to provider identification, service success rate, reliability, processing overhead, and processing latency. The performance compatibility of the VNF resource combination is a parameter for measuring the performance compatibility of the VNF resource combination, and is related to the performance parameters of the VNF resources that constitute the VNF resource combination. Wherein the performance parameter of the VNF resource may be obtained from registration information of the VNF resource.
The process of calculating, by the calculation module 210, the performance compatibility of the VNF resource combination corresponding to the service function according to the performance parameter of the VNF resource includes:
firstly, determining all VNF resource combinations corresponding to service functions;
secondly, the performance component calculating unit calculates the performance component of the VNF resource combination according to the performance parameters of all VNF resources in the VNF resource combination, wherein the performance component includes but is not limited to a provider attribute, a service success rate, reliability, processing overhead, and processing delay;
thirdly, the performance compatibility calculation unit calculates the performance compatibility of the VNF resource combination based on the performance component of the VNF resource combination;
and finally, calculating the performance compatibility of all VNF resource combinations corresponding to the service function by adopting the same method.
In one embodiment, it is assumed that a certain service function corresponds to two VNF resource combinations, and the performance components of the VNF resource combinations include provider attributes, service success rates, reliability, processing overhead, and processing latency.
The process of calculating the performance compatibility of the VNF resource combination corresponding to the service function by the calculation module is as follows:
first, the performance component calculation unit calculates the performance component of the first VNF resource combination. The specific process comprises the following steps:
the supplier attribute calculation subunit calculates the supplier attributes of the VNF resource combination according to the supplier identifications of all the VNF resources in the VNF resource combination;
the service success rate calculating subunit calculates the service success rate of the VNF resource combination according to the service success rates of all VNF resources in the VNF resource combination;
the reliability calculation subunit calculates the reliability of the VNF resource combination according to the reliability of all VNF resources in the VNF resource combination;
the processing overhead calculating subunit calculates the processing overhead of the VNF resource combination according to the processing overhead of all the VNF resources in the VNF resource combination;
and the processing delay calculating subunit calculates the processing delay of the VNF resource combination according to the processing delays of all the VNF resources in the VNF resource combination.
Secondly, the performance compatibility calculation unit calculates the performance compatibility of the first VNF resource combination according to the calculated performance component of the first VNF resource combination. The specific content comprises the following steps:
and calculating the performance compatibility of the VNF resource combination based on the supplier attribute, the service success rate, the reliability, the processing overhead and the processing time delay of the VNF resource combination.
And finally, calculating the performance compatibility of the second VNF resource combination corresponding to the service function by adopting the same method, thereby obtaining the performance compatibility of all VNF resource combinations corresponding to the service function.
For example, the service function is document retrieval, and the function types supporting the document retrieval include an input function, a search engine function, and a result presentation function, so that the function types of the VNF resource corresponding to the document retrieval also include the input function, the search engine function, and the result presentation function.
It is assumed that the performance parameters of the VNF resources are as shown in table 6.
TABLE 6
VNF resources VNF1 VNF2 VNF3 VNF4
Type of function Input device Input device Search engine Results display
Supplier identification sup1 sup1 sup2 sup1
Success rate of service 60％ 80％ 70％ 50％
Reliability of 0.8 0.7 0.5 0.6
Processing overhead 0.1 0.15 0.3 0.2
Processing time delay 0.2 0.3 0.5 0.1
As can be seen from table 6, there are two VNF resource combinations corresponding to the document retrieval service, the first VNF resource combination includes VNF1, VNF3, and VNF4, and the second VNF resource combination includes VNF2, VNF3, and VNF 4.
The process of calculating the performance compatibility of the two VNF resource combinations corresponding to the document retrieval by the calculation module is as follows:
first, the performance component calculation unit calculates the performance components of the first VNF resource combination. The method specifically comprises the following steps:
step 1: the vendor attribute calculation subunit calculates vendor attributes for the first VNF resource combination based on vendor identifications of VNF1, VNF3, and VNF 4.
Since the vendor of VNF1 and VNF4 is identified as sup1 and the vendor of VNF3 is identified as sup2, i.e. the maximum number of VNF resources identified by the vendor in the first VNF resource combination is 2(VNF1 and VNF4), therefore:
M1＝n1/N1
＝2/3
where M1 is the vendor attribute of the first VNF resource combination, n1Identifying a maximum number of identical VNF resources, N, for a provider in a first VNF resource combination1Is the number of VNF resources in the first VNF resource combination.
Step 2: the service success rate calculating subunit calculates the service success rate of the first VNF resource combination according to the service success rates of VNF1, VNF3, and VNF 4.
Figure BDA0002291780090000171
Wherein, S1 is a service success rate of the first VNF resource combination, SiI is a service success rate of each VNF resource in a first VNF resource combination, i is a first VNF resource combinationThe VNF resources in the VNF resource combination have sequence numbers, and in this example, the value of i is 1, 2, and 3, respectively.
And step 3: the reliability calculation subunit calculates the reliability of the first VNF resource combination according to the reliability of VNF1, VNF3, and VNF 4.
Figure BDA0002291780090000172
Where R1 is the reliability of the first VNF resource combination, RiFor the reliability of each VNF resource in the first VNF resource combination, i is the sequence number of the VNF resource in the first VNF resource combination, and the value of i in this example is 1, 2, and 3, respectively.
The VNF resource has a sequence number, and in this example i takes on values of 1, 2 and 3, respectively.
And 4, step 4: the processing overhead calculation subunit calculates the processing overhead of the first VNF resource combination according to the processing overhead of VNF1, VNF3, and VNF 4.
Figure BDA0002291780090000173
Where E1 is the processing overhead of the first VNF resource combination, EiFor the processing overhead of each VNF resource in the first VNF resource combination, i is the sequence number of the VNF resource in the first VNF resource combination, and the value of i in this example is 1, 2, and 3, respectively.
And 5: the processing delay calculation subunit calculates the processing delay of the first VNF resource combination according to the processing delays of VNF1, VNF3, and VNF 4.
Figure BDA0002291780090000181
Wherein D1 is the processing delay of the first VNF resource combination, DiFor the processing delay of each VNF resource in the first VNF resource combination, i is the sequence number of the VNF resource in the first VNF resource combination, and the value of i in this example is 1, 2, and 3, respectively.
And secondly, the performance compatibility calculation unit calculates the performance compatibility of the first VNF resource combination according to the calculated performance component of the first VNF resource combination.
Specifically, the performance compatibility of the VNF resource combination is calculated based on the vendor attribute, the service success rate, the reliability, the processing overhead, and the processing delay of the VNF resource combination.
Assuming that the performance compatibility calculation function is f, the performance compatibility of the first VNF resource combination can be calculated by the following formula:
C1＝f(M1，S1，R1，E1，D1)
where C1 is the performance compatibility of the first VNF resource combination.
Finally, the same method is adopted to calculate the performance compatibility of the second VNF resource combination, and the following can be obtained:
C2＝f(M2，S2，R2，E2，D2)
where C2 is performance compatibility of the second VNF resource combination, M2 is a vendor attribute of the second VNF resource combination, S2 is a service success rate of the second VNF resource combination, R2 is reliability of the second VNF resource combination, E2 is processing overhead of the second VNF resource combination, and D2 is processing latency of the second VNF resource combination.
According to the above calculation process, the performance compatibility of all the VNF resource combinations corresponding to the literature retrieval is obtained.
It should be noted that, before the calculating module 210 calculates the performance compatibility of all VNF resource combinations corresponding to the service function according to the performance parameters of the VNF resources, the following process is further included:
receiving registration information of the VNF resources, wherein the registration information comprises function types and performance parameters of the VNF resources;
and combining the VNF resources with the registered VNF resources according to the service functions and the function types of the VNF resources to form a VNF resource combination corresponding to the service functions.
For example, the function types supporting a certain service function include function type 1, function type 2, and function type 3.
It is assumed that the registered VNF resources include VNF1, VNF2, VNF3, and VNF4, and the function types of these VNF resources are as shown in table 7.
TABLE 7
Type of function Function type 1 Function type 2 Function type 3
VNF resources VNF1、VNF2 VNF3 VNF4
In the current state, the VNF resource combinations corresponding to the service functions include two types, the first VNF resource combination includes VNF1, VNF3, and VNF4, and the second VNF resource combination includes VNF2, VNF3, and VNF 4.
Assuming that registration information of the VNF5 is received, the function type and the performance Parameter (Parameter) of the VNF5, i.e., the function type 3 and the performance Parameter set (Parameter), respectively, are known from the registration information.
Since VNF5 corresponds to function type 3, combining VNF5 with registered VNF1, VNF2, VNF3, and VNF4, a new VNF resource combination corresponding to the service function can be obtained, which is: VNF1, VNF3, and VNF 5; VNF2, VNF3, and VNF 5.
At this time, all VNF resources corresponding to the service function are combined into four types, which are:
first VNF resource combination: VNF1, VNF3, and VNF 4;
a second VNF resource combination: VNF2, VNF3, and VNF 4;
a third VNF resource combination: VNF1, VNF3, and VNF 5;
a fourth VNF resource combination: VNF2, VNF3, and VNF 5.
It should be noted that after receiving the registration information of the VNF resource, the virtual resource manager needs to verify the validity of the registration information of the VNF resource. And if the validity of the registration information passes the verification, the virtual resource manager sends a notification for submitting the VNF resource to the administrator. And after receiving the notification of submitting the VNF resources, the administrator submits the corresponding VNF resources. The virtual resource manager receives the VNF resources submitted by the administrator, and further verifies the validity of the submitted VNF resources. And if the submitted VNF resource passes the validity verification, registering the VNF resource and storing the VNF resource to a corresponding position. The virtual resource manager is an abstract entity that implements the virtual resource management function, and may be software and/or hardware and/or a combination of software and hardware.
The mapping module 220 is configured to establish a mapping relationship between the performance compatibility of the virtual network function resource combination and the service level of the service function.
The service level may reflect a quality level of the service provided by the service function. The higher the service level, the higher the quality level of the service provided by the service function, and the lower the service level, the lower the quality level of the service provided by the service function. The service level is related to many factors, where performance compatibility of the VNF resource combination corresponding to the service function is one of important factors affecting the service level, that is, there is a mapping relationship between the service level and the performance compatibility of the VNF resource combination. Generally, the higher the service level, the higher the performance compatibility requirement, and conversely, the lower the service level, the lower the performance compatibility requirement. In a specific use process, the mapping relationship between the service level and the performance compatibility of the VNF resource combination may be set according to actual business requirements.
For example, assume that the service classes of the service function include class i, class ii, class iii, and class iv, where class i represents the class of service with the highest quality of service level and class iv represents the class of service with the lowest quality of service level. The performance compatibility of the VNF resource combination corresponding to the service function includes six values, 1, 2, 3, 4, 5, and 6, where the performance compatibility of the VNF resource combination is relatively best when the performance compatibility is 6, and correspondingly, the performance compatibility of the VNF resource combination is relatively worst when the performance compatibility is 1. Based on the principle that the higher the service level is, the higher the requirement on the performance compatibility of the VNF resource combination is, and in combination with the actual service requirement, the mapping module 220 establishes a mapping relationship between the performance compatibility of the VNF resource combination and the service level of the service function, as shown in table 8.
TABLE 8
Service class Performance compatibility of VNF resource combinations
Class I 6
Stage II 5
Class III 3 and 4
IV stage 1 and 2
The list establishing module 230 is configured to establish a list of the service function, the service level, the virtual network function resource combination performance compatibility, and the virtual network function resource combination based on a mapping relationship between the performance compatibility of the virtual network function resource combination and the service level of the service function.
Since there is a corresponding relationship between the service function and the service level, and there is a corresponding relationship between the VNF resource combination and the VNF resource combination performance compatibility, based on the mapping relationship between the VNF resource combination performance compatibility and the service level of the service function, which is established by the mapping module 220, a list of the service function, the service level, the VNF resource combination performance compatibility, and the VNF resource combination may be established.
For example, the service classes corresponding to the query service function include class i, class ii, class iii, and class iv, the query service function corresponds to 8 VNF resource combinations, which are a first VNF resource combination, a second VNF resource combination, a third VNF resource combination, a fourth VNF resource combination, a fifth VNF resource combination, a sixth VNF resource combination, a seventh VNF resource combination, and an eighth VNF resource combination, and the performance compatibility values of the respective corresponding VNF resource combinations are 6, 3, 4, 5, 2, 1, and 5.
Assume that the mapping relationship between the service level of the query service function and the performance compatibility of the VNF resource combination established by the mapping module 220 is shown in table 9.
TABLE 9
Service class Performance compatibility of VNF resource combinations
Class I 6
Stage II 5
Class III 3 and 4
IV stage 1 and 2
In summary, the list establishing module 230 may establish a list of service functions, service levels, VNF resource combination performance compatibility and VNF resource combinations, as shown in table 10.
Watch 10
Figure BDA0002291780090000211
As can be seen from table 10, the VNF resource combination that can provide the level i query service is the first VNF resource combination; the VNF resource combination that can provide the level ii query service is a fifth VNF resource combination and an eighth VNF resource combination; the VNF resource combination that can provide the level-iii query service is a second VNF resource combination, a third VNF resource combination, and a fourth VNF resource combination; the VNF resource combinations that may provide iv-level query services are a sixth VNF resource combination and a seventh VNF resource combination.

Providing services based on the list refers to matching corresponding VNF resource combinations for the network slice based on the list of service function, service level, virtual network function resource combination performance compatibility and virtual network function resource combination established by the list establishing module 230 according to the service function requirements and service level requirements of the network slice, and providing services for the service requirements of the network slice based on the matched VNF resource combinations.
In one embodiment, the service providing module 240 provides the service based on the list includes the following processes:
