Network element	SBC1	SBC2	CSCF	HSS	ATS
						Resources occupation rate	70%	70%	80%	80%	100%

Then the asset management device can determine that ATS is dilatation object according to the dilatation condition, if the resource The idling-resource off-capacity in pond can not can further according to the capacity reducing condition to ATS dilatations, the asset management device Can be first capacity reducing SBC1 (or SBC2) to determine sided access network element SBC1 and SBC2 as capacity reducing object, If idling-resource capacity is still not enough after capacity reducing, then capacity reducing SBC2 (or SBC1), or, Ke Yishi The low SBC of service priority in first capacity reducing SBC1 and SBC2, if idling-resource capacity is still after capacity reducing Deficiency, the then high SBC of capacity reducing service priority again, until the idling-resource capacity after capacity reducing is more than or equal to To the resource capacity needed for ATS dilatations, and to ATS dilatations.

Similar, if core side network element overburden portion, part is idle, and resources occupation rate is as shown in table 3：

Table 3

Network element	SBC1	SBC2	CSCF	HSS	ATS
						Resources occupation rate	90%	90%	80%	30%	100%

Then the asset management device can determine that ATS is dilatation object according to the dilatation condition, if the resource The idling-resource off-capacity in pond can not can further according to the capacity reducing condition to ATS dilatations, the asset management device To determine core side network element HSS as capacity reducing object, if the idling-resource capacity after HSS capacity reducings is more than or waited Resource capacity needed for ATS dilatations, then to ATS dilatations.

Similar, if the resources occupation rate of sided access network element and core side network element is all very high, and all exist The network element of overload, resources occupation rate is as shown in table 4：

Table 4

Network element	SBC1	SBC2	CSCF	HSS	ATS
						Resources occupation rate	100%	100%	90%	90%	100%

Then the asset management device can determine that the network element ATS that core side is overloaded is dilatation according to the dilatation condition Object, if the idling-resource off-capacity of the resource pool can not to ATS dilatations, due to now core side its The resources occupation rate of its network element is also very high, and the asset management device can determine access further according to the capacity reducing condition Side network element SBC1 and SBC2 are capacity reducing object, can be first capacity reducing SBC1 (or SBC2), if capacity reducing Idling-resource capacity is still not enough afterwards, then capacity reducing SBC2 (or SBC1) again, or, can be first capacity reducing The low SBC of service priority in SBC1 and SBC2, if idling-resource capacity is still not enough after capacity reducing, The high SBC of capacity reducing service priority, expands ATS until the idling-resource capacity after capacity reducing is more than or equal to again Resource capacity needed for holding, and to ATS dilatations.

Similar, if the high network element of service priority is very high all in overload or resources occupation rate, Assuming that HSS service priority is minimum, resources occupation rate is as shown in table 5：

Table 5

Network element	SBC1	SBC2	CSCF	HSS	ATS
						Resources occupation rate	90%	90%	90%	90%	100%

Then the asset management device can determine that ATS is dilatation object according to the dilatation condition, if the resource The idling-resource off-capacity in pond can not to ATS dilatations, because HSS service priority is minimum, even if this When HSS resources occupation rate it is also very high, the asset management device can determine core further according to the capacity reducing condition Side network element HSS is capacity reducing object, if the idling-resource capacity after HSS capacity reducings is more than or equal to ATS Resource capacity needed for dilatation, then to ATS dilatations.

Asked specifically, the asset management device periodically can send state parameter acquisition to the plurality of VNF Ask, and receive the plurality of VNF respond the state parameter obtain request and report resources occupation rate, business into The state parameters such as power, service priority, network site, the asset management device can also receive the plurality of The state parameter that VNF is periodically reported, wherein, the cycle can be specifically 10 seconds (English：S), 1 point Clock (English：Min) etc..

Meanwhile, the asset management device can also be periodically according to the E2E Internet resources pond (i.e. NFVI Resource) in CPU usage, the RAM occupancies etc. of bottom hardware obtain the resource occupation feelings of the resource pool Condition, to determine the idling-resource capacity in the resource pool, the cycle can be specifically 5s, 1min etc., the money The idling-resource that source control equipment obtains the cycle of the plurality of VNF state parameter with obtaining in the resource pool holds The cycle of amount can be with identical, can also be different, and for the occurrence embodiment of the present invention in the two cycles Do not limit.

S302, the asset management device determine that first is to be expanded according to the state parameter from the plurality of VNF VNF and the first resource capacity needed for dilatation.

Specifically, the asset management device determines the E2E networks according to the plurality of VNF service success rate First service success rate, first service success rate can be the product of the plurality of VNF service success rate, If first service success rate is less than or equal to default first service success rate (such as 90%), the resource Management equipment determines to start resource reconfiguration of this flow to the resource pool, and then will be somebody's turn to do in the plurality of VNF The VNF that state parameter meets default dilatation condition is used as dilatation object (being designated as the first VNF to be expanded).

Wherein, the default dilatation condition can include the one or more in following dilatation condition：Resource occupation Rate is more than or equal to default first resource occupancy (such as 90%), and service success rate is less than or equal to default the Two service success rates (such as 95%), service priority is more than or equal to default first service priority (i.e. industry Priority of being engaged in is higher), network site is rear end.If network site identical VNF has multiple, business The preferential dilatations of the high VNF of priority, for example, service success rate is less than or equal to the default second business success The VNF that rate and/or resources occupation rate are more than or equal to the default first resource occupancy has multiple, then preferential to expand Hold rear end VNF, if rear end VNF also has multiple, preferential dilatation service priority highest VNF.

Further, the asset management device determines dilatation institute according to the state parameter of first VNF to be expanded Need resource capacity (being designated as first resource capacity), specifically can according to resources occupation rate, service success rate, At least one determination in service priority and network site carries out dilatation needs to first VNF to be expanded First resource capacity, for example, resources occupation rate is higher, service success rate is lower, and service priority is higher, VNF positioned at rear end is more to the first resource capacity needed for its dilatation.Usually, the first resource holds Amount can be the capacity of the resources such as CPU, RAM required when related software is run on a VM and VNF, I.e. dilatation when the asset management device using a VM as dilatation granularity.

In some feasible embodiments, the asset management device can also be in the E2E networks Current-carrying control state (i.e. resources occupation rate is 100%) or resources occupation rate exceed a certain threshold value (such as 97%) VNF quantity exceed predetermined number (such as 3) when, it is determined that starting this flow to the resource pool Resource reconfiguration.The asset management device can also be in current-carrying control state or money in the E2E networks Source occupancy exceed a certain threshold value VNF quantity exceed predetermined number, and the E2E networks business into When power is less than or equal to a certain threshold value, it is determined that starting resource reconfiguration of this flow to the resource pool.I.e. In the embodiment of the present invention, the asset management device can be according to the service success rate of the E2E networks and each At least one in VNF resources occupation rate determines the need for starting resource of this flow to the resource pool Reconfigure.

S303, when resource pool idling-resource capacity be less than the first resource capacity when, the asset management device Determine that first treats capacity reducing VNF from the plurality of VNF according to the state parameter, and according to the first resource capacity To this first treat capacity reducing VNF carry out capacity reducing processing.

If entered specifically, the current idling-resource capacity of the resource pool does not reach to first VNF to be expanded , can not be in the case of dilatation in the resource pool during first resource capacity needed for row dilatation, the resource management is set Standby to carry out dilatation to first VNF to be expanded, now the asset management device can be by the plurality of VNF In the state parameter meet the VNF of default capacity reducing condition and (be designated as first as capacity reducing object and treat capacity reducing VNF).

Wherein, the default capacity reducing condition includes the one or more in following capacity reducing condition：Resources occupation rate is small In or equal to default Secondary resource occupancy (such as 75%), service success rate, which is more than or equal to, presets the 3rd industry Success rate of being engaged in (such as 97%), service priority is less than or equal to default second service priority, and (i.e. business is excellent First level is relatively low), network site is front end.If network site identical VNF has multiple, business is preferential The low preferential capacity reducings of VNF of level, for example, service success rate be more than or equal to default 3rd service success rate and / or resources occupation rate be less than or equal to VNF of the default Secondary resource occupancy and have multiple, then before preferential capacity reducing Hold VNF, if front end VNF also has multiple, the minimum VNF of preferential capacity reducing service priority.

Further, the first resource capacity of the asset management device according to needed for dilatation first is waited to contract to this Hold VNF carry out capacity reducing processing, with cause this first treat capacity reducing VNF discharge part resource, capacity reducing processing Concrete mode can be：The asset management device obtains this and first treats the VM operation that is run on capacity reducing VNF State, includes VM quantity, each VM CPU usage and RAM occupancies etc., and then according to The first resource capacity and the running status determine that the VM to be closed of resource can be discharged, and this is waited to close VM close so that this first treat capacity reducing VNF discharge part resource, to increase the idling-resource of the resource pool Capacity.General, the asset management device can be using a VM as capacity reducing granularity during capacity reducing.

S304, according to the first resource capacity first capacity reducing VNF, which contracts, to be treated to this when the asset management device After appearance processing, when the idling-resource capacity of the resource pool is more than or equal to the first resource capacity, the resource Management equipment carries out dilatation processing to first VNF to be expanded.

Specifically, this is first after after capacity reducing VNF capacity reducings, if the current idling-resource capacity of the resource pool reaches The first resource capacity arrived needed for dilatation, then the asset management device can be to first VNF to be expanded Dilatation processing is carried out, the concrete mode of dilatation processing can be：If without on first VNF to be expanded Create but not actuated VM, then the asset management device created on first VNF to be expanded one or Multiple VM, and by the resource distribution of the first resource capacity to one or more VM created, start wound One or more VM built；Created but not actuated VM if existed on first VNF to be expanded, Then the asset management device can start this and create but not actuated VM, by the resource of the first resource capacity This is allocated to have created but not actuated VM.Wherein, while VM starts, the upper related business of VNF, The softwares such as monitoring can also start.

In some feasible embodiments, if this first after capacity reducing VNF capacity reducings release part resource after, The idling-resource capacity of the resource pool is still reached to less than the first resource capacity needed for dilatation, then the resource pipe Reason equipment can obtain the plurality of VNF state parameter again, and according to the plurality of VNF obtained again State parameter capacity reducing object (be designated as second and treat capacity reducing VNF) is determined from the plurality of VNF.Certainly, exist This first after after capacity reducing VNF capacity reducings if state (including service success rate, each VNF of the E2E networks Resources occupation rate etc.) it is no vary widely, then the asset management device can also be utilized directly in step The plurality of VNF obtained in rapid S301 state parameter determines that this second treats capacity reducing VNF.

Further, the asset management device holds according to the idling-resource capacity and the first resource of the resource pool Amount determines to need the resource capacity that is obtained again by capacity reducing, and second treats that capacity reducing VNF is carried out at capacity reducing to this Reason, if this is second after after capacity reducing VNF capacity reducings, the idling-resource capacity of the resource pool has been reached needed for dilatation The first resource capacity, then the asset management device dilatation processing just is carried out to first VNF to be expanded.

In the embodiment of the present invention, asset management device obtains the state parameter for multiple VNF that E2E networks include, The E2E networks service success rate be less than preset value when, according to the state parameter from the plurality of VNF really Make the first resource capacity needed for the first VNF to be expanded and dilatation；If the current idling-resource of resource pool Capacity be less than the first resource capacity, then the asset management device according to the state parameter from the plurality of VNF Determine that first treats capacity reducing VNF, and first capacity reducing VNF, which carries out capacity reducing, to be treated to this according to the first resource capacity Processing, to discharge resource into the resource pool, is somebody's turn to do until the idling-resource capacity of the resource pool is more than or equal to First resource capacity, the asset management device carries out dilatation processing to first VNF to be expanded, so as to In the case of idling-resource deficiency in resource pool between each VNF of guarantee resource in E2E networks Weighing apparatus configuration, and then improve resource utilization and the service success rate of E2E networks.

Referring to Fig. 4, for the embodiment of the present invention based on the E2E network architectures shown in Fig. 1 provide it is another The schematic flow sheet of method for managing resource.Wherein, the E2E networks include multiple VNF and managed the plurality of VNF and resource pool asset management device, the method for managing resource described in the present embodiment, including：

Wherein, step S401~step S403 is identical with step S301~step S303 in preceding embodiment, Here is omitted for the embodiment of the present invention.

S404, the asset management device obtain the plurality of VNF state parameter again.

S405, the asset management device determine E2E according to the plurality of VNF obtained again service success rate Second service success rate of network.

Specifically, this is first after after capacity reducing VNF capacity reducings, due to load balancing again between the plurality of VNF The regular hour is needed, the asset management device can wait the duration in an observation cycle, the observation cycle It can be the cycle for the state parameter for obtaining the plurality of VNF, such as 10s reaches the observation when waiting time During the cycle, the asset management device obtains the plurality of VNF state parameter again, and according to obtaining again The plurality of VNF service success rate determines the second service success rate of the now E2E networks, second business Success rate can be the product of the plurality of VNF service success rate.

S406, the asset management device judge whether second service success rate is less than the first of the E2E networks Service success rate, and first service success rate subtracts the difference of second service success rate more than or equal to pre- If the first numerical value, if so, then performing step S407；If it is not, then performing step S408 and step S409.

Specifically, the asset management device first treats capacity reducing VNF by comparing second service success rate with this First service success rate before capacity reducing determined to this first after after capacity reducing VNF capacity reducings, the E2E networks Whether service success rate is decreased obviously, i.e., first service success rate subtracts the difference of second service success rate Whether value is more than or equal to default first numerical value (such as 3%), if the service success rate of the E2E networks has It is decreased obviously, then performs step S407；If the service success rate of the E2E networks be not decreased obviously or Rise, then perform step S408 and step S409.

S407, the asset management device to this first treat capacity reducing VNF carry out capacity reducing processing carry out rollback behaviour Make.

Specifically, this is first after after capacity reducing VNF capacity reducings, if the service success rate of the E2E networks has substantially Decline, then the asset management device by this first treat the release of capacity reducing VNF capacity reducings resource re-allocate to this One treats capacity reducing VNF, starts the VM to be closed, and cancels and first treats that capacity reducing VNF capacity reducing is handled to this, makes Obtain the E2E networks and return to this as far as possible and first treat state before capacity reducing VNF capacity reducings, with weaken this One treats that capacity reducing VNF capacity reducings cause being decreased obviously for the E2E Network success rates.

S408, according to the first resource capacity first capacity reducing VNF, which contracts, to be treated to this when the asset management device After appearance processing, when the idling-resource capacity of the resource pool is more than or equal to the first resource capacity, the resource Management equipment carries out dilatation processing to first VNF to be expanded.

S409, it is more than or equal to first service success rate, and second business when second service success rate The difference that success rate subtracts first service success rate is less than or equal to default second value, or, this second Service success rate is less than first service success rate, and first service success rate subtracts second business success When the difference of rate is less than or equal to default third value, asset management device delay preset duration, and prolonging When during VNF to be expanded and expansion are not determined from the plurality of VNF according to the plurality of VNF state parameter Resource capacity needed for holding.

Specifically, the asset management device is by comparing second service success rate and first service success rate Determine whether the service success rate of the E2E networks has substantially to rise or slightly decline, if second business Success rate is more than or equal to first service success rate, and second service success rate subtracts first business The difference of success rate is less than or equal to default second value (such as 5%), then the asset management device determines to be somebody's turn to do The service success rate of E2E networks does not substantially rise.If second service success rate is less than first business Success rate, and first service success rate subtracts the difference of second service success rate less than or equal to default Third value (such as 2%), then the asset management device determine that the service success rate of the E2E networks has slightly Decline.

Further, the service success rate for determining the E2E networks in the asset management device does not substantially rise Or when having small size decline, the asset management device can be delayed preset duration, and the no longer root during being delayed The resource needed for VNF to be expanded and dilatation is determined from the plurality of VNF according to the plurality of VNF state parameter Capacity, that is, suspend capacity reducing to VNF, dilatation, and preset duration can be three times in the plurality of VNF of acquisition State parameter cycle.

Further, the asset management device can carry out capacity reducing determining continuous several times (such as 3 times) When the service success rate of the E2E networks does not still substantially rise or has small size decline after being handled with dilatation In the case of, just be delayed preset duration, and during being delayed no longer according to the plurality of VNF state parameter from this The resource capacity needed for VNF to be expanded and dilatation is determined in multiple VNF, certain erroneous judgement once is prevented And cause capacity reducing of the asset management device pause to VNF, dilatation.

It should be noted that the asset management device still can periodically obtain the plurality of during being delayed The idling-resource capacity of VNF state parameter and the resource pool.
