In order to make those skilled in the art more fully understand the technical solution in the embodiment of the present invention, and make of the invention real The above objects, features, and advantages for applying example can be more obvious and easy to understand, below in conjunction with the accompanying drawings to technical side in the embodiment of the present invention Case is described in further detail.

The embodiment of the present invention provides distribution method, composer and the manager of Internet resources in a kind of virtual network function, It can realize after NS generations, the dynamic of NS available resources adjusts, and ensures the availability and continuity of NS.

The method of the embodiment of the present invention and device propose, under NFV environment, when NS is generated, increase by one in NSD NSAI indicates that NS can use more than the resource information situation of signing value, the as information of standby resources, in operator and visitor When family is contracted, pot life, type and the quantity of this part standby resources are determined.

Referring to Fig.1, it is the flow of the distribution method of Internet resources in the virtual network function described in the embodiment of the present invention one Figure, the method includes：

Step S101：The NSD that OSS or BSS is sent；The NSD includes the signing resource information and NSAI information of NS；Institute State the information that NSAI is used to indicate the standby resources of the NS；

Step S102：Obtain the abnormal performance data for the VNF being currently abnormal；

Step S103：When it is performance overload or too low performance to determine the VNF, believed according to the signing resource of the NS The abnormal performance data of the information and the VNF of the standby resources that breath, the NSAI are indicated, formulate corresponding NSRRHP；

Step S104：The NSRRHP is respectively sent to VNFM and VIM.

：The method of the embodiment of the present invention increases the NSAI of the information for the standby resources for being used to indicate the NS, in determination When the abnormal alarm that performance is overloaded or performance is too low occurs for VNF, indicated according to the signing resource information of NS, the NSAI spare The abnormal performance data of the information of resource and the VNF, formulate corresponding NSRRHP, for VNF dynamics adjust its NS can With resource, to ensure the availability and continuity of NS.

The method of the embodiment of the present invention one is applied to the scene of Orchestrator (composer) decision.

Under the scene, VNFM is responsible for reporting EMS (Element Management System, Element management system) Abnormal alarm analyzed and determined judge whether it is caused by current NS resources are too little or too much, if it is not, then taking other Fault management mechanism is restored；If it is, the abnormal alarm is sent to Orchestrator processing.

In the embodiment, reserved resource is made according to the Exception Type of VNF and the information of NSAI by Orchestrator Decision is handled, and is issued to VNFM and VIM and executes corresponding action.

With reference to Fig. 2 and the embodiment of the present invention two, the method described in embodiment one is described in detail.

With reference to Fig. 2, for the signaling process figure of the distribution method of Internet resources in the VNF of the embodiment of the present invention two.Such as Fig. 2 institutes Show, the described method comprises the following steps：

Step S201：OSS/BSS sends NSD to Orchestrator；Wherein, the NSD includes the signing resource of NS Information and NSAI information.

The case where NSAI information is used to indicate the standby resources of the NS, which, which is the NS, to use More than the resource of signing value.Wherein, which refers to the quantity of NS signing resources.

In the embodiment of the present invention, when operator and client contract, the information for the resource that NS normal uses need is determined, also It referred to as contracts resource information.The information for the resource that NS can additionally be used, as standby resources information can also be determined simultaneously.

Correspondingly, operator disposes Internet resources, it is reserved resource to delimit a part of resource in advance, the reserved money Source is used to provide standby resources because in the case that NS shortages of resources cause network failure for VNF in VNF.For example, can set Resource deployment is：90~95% be operation resource, and 5~10% be reserved resource.

The case where specifically, in the embodiment of the present invention, increasing NSAI in NSD, being used to indicate the standby resources.By OSS/ NSD comprising NSAI is sent to Orchestrator by BSS.

It should be noted that at least may include in the NSAI information：NSID, standby resources pot life, standby resources Type and quantity etc..

Specifically, the NSID is used to indicate the applicable NS of the standby resources for identifying NS.

The pot life of standby resources is used to indicate the standby resources from start-up time, the maximum duration that can be used. For example, can be a few houres or several days etc..

It should be noted that standby resources are mainly used in the case that client needs vast resources suddenly, one this feelings The condition duration will not be too long.If for example, client for a long time need vast resources, one big flow that all can directly contract. Therefore, the holding time of the standby resources is not generally too long, to ensure that the standby resources will not be accounted for for a long time after unlatching With, ensure that standby resources are timely released after meeting customer need, in order to avoid result in waste of resources.

The type and quantity of standby resources are used to indicate the type of the standby resources that the NSAI includes and all types of The corresponding quantity of standby resources.For example, the type of standby resources can be：Software resource and hardware resource.Wherein, software Resource may include bandwidth resources, virtual linkage resource etc.；Hardware resource may include VM resources, PNF resources etc..

It may include the type of a variety of standby resources in the NSAI information, and all types of standby resources be set separately and correspond to Quantity.For example, for VNF resources, it is assumed that its signing value is 30MHz, and the maximum quantity for wanting to increase in NS is 100MHz.Then the NSAI information includes following information：Standby resources type is VNF resources, quantity 100MHz.

It should be noted that the every terms of information that the NSAI includes, can by client in signing according to actual need It specifically to set.

Step S202：EMS obtains the runnability situation of each VNF in NS.

Specifically, EMS can periodically monitor the runnability of each VNF in NS；Alternatively, EMS can also periodically connect Receive the runnability information that each VNF is reported in NS.

Wherein, the runnability of VNF may include：Bandwidth usage amount, handling capacity, time delay etc..

Step S203：When EMS has found that abnormal performance alarm occurs for some VNF, by the abnormal performance warning message of the VNF Report to VNFM.

Step S204：After VNFM receives the abnormal performance warning message for certain VNF that EMS is reported, according to the abnormal performance Warning message determines whether that performance is overloaded, if it is, entering step S205；If it is not, then according to old process to this Abnormal performance alarm is handled.

Specifically, after VNFM receives the abnormal performance warning message of the VNF, which is analyzed and determined, Caused by determining whether the exception is NS performances overload, it can be solved by increasing NS resources, if it does, then to this VNF opens standby resources, and the abnormal alarm is solved by increasing NS resources.

Specifically, including abnormal performance data in the abnormal alarm information, analyzed according to the abnormal performance data, When the resource utilization of the VNF is higher than preset first threshold, it may be determined that the abnormal performance warning message is the VNF performances Overload.

Step S205：VNFM sends NSRRR message to Orchestrator；Wherein, NSRRR includes network resource operation The abnormal performance data of mark and the VNF.

Specifically, may include network resource operation mark in the NSRRR, when VNFM determines that current exception is performance mistake Carry, when needing to open the standby resources of NS for the VNF, can set the operation marks of the Internet resources of the NSRRR as Increasing means unlatching standby resources.

Step S206：Orchestrator receives the NSRRR message of VNFM transmissions, is identified according to the network resource operation Determine current abnormal for performance overload, the then standby resources that Orchestrator is indicated according to the signing resource information of NS, NSAI Information and VNF abnormal performance data, formulate corresponding network service reserve resource processing strategy NSRRHP, enter step S207a and S207b.

Specifically, information and the institute of the standby resources indicated according to the signing resource information of the NS, the NSAI The abnormal performance data for stating VNF, formulating corresponding NSRRHP includes：

The abnormal performance data for the VNF that Orchestrator includes according to the NSRRR message determine current generation property The type for the resource that can be overloaded, as determination, which are currently that the resource appearance of which type is in short supply, to be caused to be abnormal alarm.

Orchestrator inquires the information of the standby resources of the NSAI instructions, obtains the current generation performance overload Type standby resources quantity；In other words, Orchestrator inquires the standby resources information of NSAI instructions, and determination can be with The standby resources of which type are opened for the VNF.

Meanwhile Orchestrator also inquires the signing resource information of the NS, obtains the current generation performance overload Type resource signing quantity.

Orchestrator formulates the NSRRHP：Open the spare money of the current type that performance overload occurs Source so that the quantity of the available resources of the type is that the quantity of the standby resources of the type adds the signing number of the type Amount

Specifically, assuming the data information of the NS performances overload in the NSRRR message that current Orchestrator is received It points out, the VNF resources needed for the VNF are 80MHz, and the VNF signing values of the client are only 30MHz.Orchestrator passes through NSAI received from OSS/BSS in step S201 is it is found that the VNF standby resources of the client are 100MHz.

Then Orchestrator formulations NSRRHP is：VNF standby resources are opened for the VNF so that the VNF available resources Quantity is 130MHz, to solve current failure.

It should be noted that in the embodiment of the present invention two, alarmed according to the abnormal performance of EMS certain VNF reported by VNFM Information is analyzed and determined, when it is performance overload to determine the abnormal alarm, passes through the network resource operation for including in NSRRR Mark informs that the Orchestrator exceptions are overloaded for performance, needs to open standby resources for the VNF.

Further, in other embodiments of the present invention, this method can also include：VNFM directly EMS is reported certain The abnormal performance warning message of VNF is sent to Orchestrator.By Orchestrator to the abnormal performance warning message into Row analyzes and determines；When the resource utilization that the information includes is higher than preset first threshold, Orchestrator is determined should VNF overloads for performance, needs to open standby resources for the VNF.

Step S207a：Orchestrator sends NSRRHP message to VNFM, enters step S208a；Wherein, described NSRRHP message includes the policy information being extended to VNF resources.

Wherein, VNF resources refer to the software resource of NS, for example, bandwidth resources, virtual linkage resource etc..

Step S207b：Orchestrator sends NSRRHP message to VIM, enters step S208b；Wherein, described NSRRHP message includes being extended to NFVI (NFV Infrastructure, network function virtualized infrastructure) resource Policy information.

Wherein, NFVI resources refer to the hardware resource of NS, for example, VM resources, PNF resources etc..

Step S208a：After VNFM receives the NSRRHP message, according to the strategy in the NSRRHP message, execute to VNF The standby resources of VNF are as opened in the extended operation of resource.

Step S208b：After VIM receives the NSRRHP message, according to the strategy in the NSRRHP message, execute to NFVI The standby resources of NFVI are as opened in the extended operation of resource.

Pass through the above method so that client can not only use the resource of defined normal use when contracting, moreover it is possible to use The standby resources of defined in NSAI avoid the abnormal interrupt of business, meet client's it is possible thereby to which the overload for eliminating NS is abnormal Use demand improves the availability and duration of NS.

To avoid the NS wastings of resources and ensureing that other VNF use standby resources, the method for the embodiment of the present invention also to wrap It includes：The VNF NS overloads it is abnormal eliminate or reach the pot life of standby resources after, standby resources which is occupied into Row release.

Still with Fig. 2, after step S208a and S208b, the method further includes：

Step S209：EMS obtains the runnability situation of each VNF in NS.

Wherein, the runnability of VNF may include：Bandwidth usage amount, data throughout, time delay etc..

Step S210：When EMS has found that abnormal performance alarm occurs for some VNF, by the abnormal performance warning message of the VNF Report to VNFM.

Step S211：After VNFM receives the abnormal performance warning message for certain VNF that EMS is reported, judge whether that needs are The VNF discharges the standby resources of NS, if necessary to discharge, then enters step S212；Otherwise, then according to old process to the performance Abnormal alarm is handled.

Specifically, after VNFM receives the abnormal performance warning message of certain VNF that the EMS is reported, according to the abnormal performance Warning message determines whether that performance is too low and opened standby resources, if it is, entering step S212；If it is not, then Abnormal performance alarm is handled according to old process.

Specifically, after VNFM receives the abnormal performance warning message of VNF, which is analyzed, determining should Caused by the abnormal NS performances for whether being VNF are too low, for example, being carried out according to the abnormal performance data in abnormal performance warning message It analyzes and determines, when the resource utilization of VNF is less than preset second threshold, it may be determined that the alarm is that VNF performances are too low.

When then further judging whether to open standby resources before the VNF, if opened, it is determined that need for this VNF discharges the standby resources of NS；If it is not, being handled abnormal performance alarm according to old process.

Specifically, VNFM is according to the parameter information in the NS performance parameters and NSAI of the VNF, to judge to be before the VNF It is no to open standby resources.

For example, VNFM determines that the signing value of the VNF is only 30MHz, but works as by inquiring the NS performance parameters of the VNF The actually available resource value of the preceding VNF is 130MHz, meanwhile, by NSAI it is found that spare VNFs of the NS with 100MHz is provided Source.It is possible thereby to determine, which opened standby resources.

Since the resource utilization of the current VNF is too low, it is known that, which needs not continue to occupy the standby resources, by The standby resources can be carried out release operation, to avoid the wasting of resources by this.

Step S212：VNFM sends NSRRR message to Orchestrator；Wherein, NSRRR includes network resource operation The abnormal performance data of mark and the VNF.

Specifically, may include network resource operation mark in the NSRRR, when VNFM determines that current exception is performance mistake It is low, when needing to discharge the standby resources of NS for the VNF, can set the operation marks of the Internet resources of the NSRRR as Decreasing means release standby resources.

Step S213：Orchestrator receives the NSRRR message of VNFM transmissions, determines that the network resource operation identifies Determine the standby resources that current exception is that performance is too low, then Orchestrator is indicated according to the signing resource information of NS, NSAI Information and VNF abnormal performance data, formulate corresponding network service reserve resource processing strategy NSRRHP, enter step S214a and S214b.

The abnormal performance data for the VNF that Orchestrator includes according to the NSRRR message determine current generation property Can too low resource type, as determination is currently that utilization rate occur too low and cause to be abnormal report for the resource of which type It is alert.

Orchestrator inquires the signing resource information of the NS, obtains the current generation too low type of performance The signing quantity of resource.

When the quantity of the available resources of the type is more than the signing quantity of the type, the resource of the type is determined Opened standby resources.

Orchestrator formulates the NSRRHP：Discharge the standby resources of the type so that the type can With the signing value that the quantity of resource is the type.

Specifically, assuming the too low data information of NS performances in the NSRRR message that current Orchestrator is received It points out, the VNF resources needed for the VNF are only 10MHz, and the VNF resources that the client can currently use are 130MHz, the VNF Signing value is 30MHz.Orchestrator is by NSAI it is found that the VNF standby resources of the client are 100MHz.

Then Orchestrator formulates standby resources processing strategy, is determined as VNF release VNF standby resources so that should The signing value of VNF itself can meet the needs of current, to avoid the waste of resource.

It should be noted that in the embodiment of the present invention two, it can be by VNFM according to the abnormal performance of EMS certain VNF reported Warning message is analyzed and determined, when it is that performance is too low to determine the abnormal alarm, passes through the Internet resources for including in NSRRR Operation mark informs that the Orchestrator exceptions are overloaded for performance, needs to discharge standby resources for the VNF.
