Referring to Fig. 3, Fig. 3 is a kind of flow diagram of network slice method for mapping resource provided by the embodiments of the present application. Network slice resource mapping apparatus 10 in above-mentioned Fig. 2 walks for supporting and performing the method flow step S201- shown in Fig. 3 Rapid S203 optionally, is additionally operable to support and performs method flow step S204-S205.It should be noted that in order to become apparent from detail Network slice method for mapping resource in thin description the embodiment of the present application, the application describe accordingly in each process step Executive agent, but corresponding method stream can only be performed by described executive agent by not representing the embodiment of the present application Journey.
Below with reference to the NFV frameworks that Fig. 1 is described using Sender, NS/Slice Policy Agent and MANO as in detail Thin executive agent is described, wherein, Sender can be configuration manager, OSS/BSS in NFV；NS/Slice Policy Agent can be the processing module that the processing module in NFV frameworks is either integrated with MANO.It is understood that above-mentioned hold Row main body can also be independent from each other network element or equipment, and the application is not especially limited this, as long as correlation technique can be performed The executive agent of flow belongs to the application and protects the range covered.
Step S201：The instantiation that Sender sends network slice to NS/Slice Policy Agent is asked；NS/ Slice Policy Agent receive the instantiation request of network slice.
Specifically, Sender sends the instantiation request of network slice, NS/Slice to NS/Slice Policy Agent Policy Agent receive the instantiation request of network slice, and the network slice includes M virtualization network function VNF, The M VNF includes N number of virtualization network function component VNFC, and the instantiation request is included in N number of VNFC The resource requirement information of each VNFC, wherein, the N and M are the integer more than 1.Instantiation request can include network Each VNFC resource requirements of slice and/or link resource needs.
For example, as shown in figure 4, Fig. 4 is the specific of network slice method for mapping resource provided by the embodiments of the present application Application scenario diagram, it is assumed that it needs to instantiate network slice 1 in Fig. 4, and network slice 1 is by VNFAAnd VNFBIt connects and composes, VNFA It is by VNFC againA1Composition, VNFBThen by VNFCB1、VNFCB2VNFC links VL between the twoB1-B2Composition, VNFAAnd VNFBIt Between have VNFC links VLA1-B1, then VNFC can be respectively included by instantiating in requestA1、VNFCB1And VNFCB2Host resource requirements Size and VLB1-B2And VLA1-B2Bandwidth resources demand size.
Step S202：The first priority of N number of VNFC is determined according to the resource requirement information.
Specifically, due to the NS/Slice mappings in the prior art, supported under NFV frameworks, mapping mode is first to complete The mapping of each VNF units of NS/Slice is formed, i.e., each VNF independently maps.By taking the application scenarios of Fig. 4 as an example, first map VNFARe-map VNFB, map VNFBWhen, including mapping VNFCB1、VNFCB2And VLB1-B2, link between VNF is then carried out again Map (i.e. VNFAAnd VNFBBetween VNFC links VLA1-B2).Therefore, it is to regard each VNF as to have no close in the prior art The individual of system, each VNF mappings individually consider, the resource requirement of more VNF is not considered together so that network slice distribution resource When cannot accomplish to consider from the overall situation, cause mapping network be sliced physical resource consumption cannot be optimal, i.e., physics provide Source consuming cost is excessive.For example, in some cases, multiple VNFC in same VNF may be led due to functional requirement difference Cause resource requirement, cpu demand or memory space requirements different, but since same VNF in the prior art is uniformly to carry out Host resource impacts, therefore the different VNFC that can not be directed in same VNF carry out targetedly different Host resources and reflect It penetrates, therefore the waste of physical resource is likely to result in for the smaller VNFC of certain resource requirements, and for certain resource requirements Higher VNFC can may cause the deficiency of physical resource again.And in the embodiment of the present application, in a network is sliced The resource requirement of all VNF is considered as a whole, is made rational planning for, for different VNFC according to its first priority height, respectively into The Host resource allocations of row " personalization " are embodied in the distribution that all VNFC in all VNF plan as a whole with resource Mapping.
It should be noted that the first priority is carried out by height on earth or by low to N number of VNFC according to resource requirement information To high sequence, the decision factor of the first priority therein can be the function of different VNFC；Can also be by not The resource requirement size of same VNFC, the demand size of demand size, memory space such as CPU, the security requirement of data are big Demand size of small and data processing speeds etc., carries out all VNFC the sequence of the first priority, and generation first is excellent The list of first grade height sequence.
In a kind of possible realization method, the resource requirement information includes the resource requirement size of VNFC, according to money Source demand information carries out the first priority ranking to N number of VNFC：According to the resource requirement size of N number of VNFC to the N A VNFC carries out the first priority ranking, and the resource requirement size is bigger, and corresponding first priority is higher.I.e. It, therefore, can by the way that the VNFC of resource requirement size bigger is set as the higher rank of the first priority in the embodiment of the present application With when Host resource allocations are carried out, preferential distribution or distribution obtain more good Host resources.
Step S203：NS/Slice Policy Agent determine N number of VNFC according to the height of first priority With the correspondence between host Host, the correspondence is used to perform the mapping of Host resources for N number of VNFC.

Specifically, the resource requirement information is included between resource requirement size and the N number of VNFC of VNFC VNFC topological relations, and topological relation is mainly the link connection relationship included between VNFC, i.e. VNFC links refer to two Link between adjacent VNFC.
Equally, comparatively, difference lies in not only only will embodiment corresponding with Fig. 3 and Fig. 5 in the embodiment of the present application Unique factor of judgment of the VNFC own resources demand sizes as its first priority height, also by the adjacent VNFC's of VNFC Judgment basis of the resource requirement size as its first priority height, because in the mapping process of follow-up Host resources, meeting Preferentially adjacent Host is mapped on same Host, to avoid needing to establish VNFC links, waste bandwidth between adjacent VNFC Resource, and if VNFC its adjacent VNFC resource requirement it is bigger, also turn out that the interaction of the VNFC and these VNFC is got over It is more, and if the resources requirement of adjacent VNFC is larger, can be with the first priority higher of the indirect proof VNFC.
Step S403：NS/Slice Policy Agent calculate each VNFC respectively according to the resource requirement size of VNFC And the total resources demand size of adjacent VNFC.
In a kind of possible realization method, the resource requirement size of adjacent VNFC can also be multiplied by certain weight Coefficient, then be added, then be ranked up with VNFC own resources demand sizes, as long as in short, in view of adjacent VNFC's The factor of available resources size, the total resources demand for specifically how carrying out whole (including VNFC and its adjacent VNFC) are big Small weighting can be not especially limited this with flexible, the application.
Step S404：NS/Slice Policy Agent determine N number of VNFC's according to the total resources demand size First priority, wherein, total resources demand is bigger, and corresponding first priority is higher.
Step S405：The available resource information of L Host in data center's DC networks is reported to NS/Slice by MANO Policy Agent；NS/Slice Policy Agent obtain the available resource information of L Host in data center's DC networks.
Specifically, the available resource information is included between current available resource size and the L Host of Host Host topological relations.The available resource information of L Host in the embodiment of the present application, which not only includes each Host, to be carried The type and size of the resource of confession further comprise the topological relation between L Host, i.e. connecting link between Host and Host Etc. information, in order to which the VNFC links subsequently between VNFC distribute corresponding bandwidth resources.
Step S406：NS/Slice Policy Agent obtain the adjacent of each Host according to the Host topological relations Host, wherein, being established between adjacent two Host has Host links.
Specifically, by the topological relation between the Host that is obtained in step S405, know the adjacent Host of each Host, Obtain the Host that Host links are established with the Host.
Step S407：NS/Slice Policy Agent calculate each Host respectively according to the available resources size of Host And the available total resources size of adjacent Host；
Specifically, total available resources size of each Host and its adjacent Host is calculated, obtain each Host can With total resources size (available resources for including its adjacent Host).
Step S408：NS/Slice Policy Agent can determine the L Host's according to total resources size Service quality rating, wherein, it can be bigger with total resources, corresponding service quality rating is higher.
Specifically, after statistics obtains each Host and the corresponding total available resources sizes of its adjacent Host, then to every For a Host according to that can carry out service quality rating sequence with total resources size, principle of ordering is that available total resources are bigger, corresponding Service quality rating is higher, and difference lies in the services of the Host in Fig. 5 for the embodiment of the present application application embodiment corresponding with Fig. 5 The grade of quality is only related with the available resources size of itself, itself available resources is bigger, then the grade of corresponding service quality It is higher.And in the embodiment of the present application, the available resources size of Host itself is not only considered, also by the available of the adjacent Host of Host The factor of resource size takes into account, because adjacent Host is that the Host for having Host links is established between the Host, and also just It is due to the Host links, can just allow between Host Host adjacent thereto can share Host resources.Therefore if Host is in itself The available resources provided are little, but its adjacent Host is more, and the available resources of adjacent Host are larger, then can also between be connected in The Host provides available resources in itself, so when a Host its adjacent Host is more and available resources are more, can also carry Rise the grade of the service quality of the Host in itself.
In a kind of possible realization method, the available resources size of adjacent Host can also be multiplied by certain weight Coefficient, then be added, then be ranked up with the available resources sizes of Host in itself, as long as in short, in view of adjacent Host's The factor of available resources size, the available total resources for specifically how carrying out whole (including Host and its adjacent Host) are big Small weighting can be not especially limited this with flexible, the application.
Step S409：NS/Slice Policy Agent are preferential by do not determine the correspondence currently described first The corresponding Host of the highest target VNFC of grade are determined as target Host, and by the corresponding Host of adjacent VNFC of the target VNFC It is determined as the target Host, the target Host is the highest Host of the service quality rating that can currently map.
Specifically, in the embodiment of the present application when determining the correspondence between VNFC and Host, considered first from total money Source demand size maximum, it that is to say that the first highest target VNFC starts to determine, for the physics in the DC resource pools of its mapping Resource is naturally also the highest target Host of service quality rating.Next, exist different from the distinctive points of the corresponding embodiments of Fig. 3 In the embodiment of the present application not only directly carries out Host resources according to the height of its first priority to all VNFC to it Distribution correspond to, but some VNFC has been carried out Host correspond to after, pay the utmost attention to its adjacent VNFC corresponding to this VNFC determined on corresponding same Host, the reason is that, being established between adjacent VNFC has VNFC links, if can will be adjacent VNFC is mapped on same Host, then can save VNFC links, because communicating inside same Host, is not needed to By VNFC links, i.e., it need not consume bandwidth resources.
In a kind of possible realization method, according to the height of first priority, successively by the target VNFC's The corresponding Host of adjacent VNFC is determined as the target Host；It is judged to working as by not corresponding to the adjacent VNFC of the target Host The preceding VNFC for not determining the correspondence.I.e. after target Host has been corresponded to for target VNFC, mesh is corresponded to for adjacent VNFC When marking Host, equally successively target Host resources can be carried out for adjacent VNFC according to the first priority height of adjacent VNFC It is corresponding.If during being corresponding in turn to, if since the physical resource on current target Host is limited, it is all to lead to not Adjacent VNFC completes the correspondence of Host, then, the VNFC for not completing Host resource impacts is judged to not completing Host at this time The VNFC of resource impact, then it is follow-up need not correspond to this to the adjacent VNFC of target Host be determined as it is current do not determine it is described right The VNFC that should be related to, therefore subsequently need to re-start determining for the correspondence of Host.
Step S410：NS/Slice Policy Agent execution will be described not to be determined described in the correspondence currently The step of corresponding Host of target VNFC of first highest priority are determined as target Host, until N number of VNFC is determined Complete corresponding Host.
Specifically, judging result and the current all VNFC for having not determined correspondence based on step S409, again It recycles and performs according to step S409, that is, weed out that current to have completed the first priority that Host correspondences determine higher The VNFC and higher adjacent VNFC of its corresponding first priority, determines failure by correspondence and does not correspond to also Determining all VNFC of relationship re-start mapping according to the mapping ruler of step S409 again, so move in circles, Zhi Daosuo The relationship that some VNFC complete corresponding Host determines.
By taking the corresponding concrete application scene figures of Fig. 4 as an example, it is assumed that the first of all VNFC of the network slice 1 in Fig. 4 is excellent First grade sequence, is from high to low VNFCB1、VNFCA1、VNFCB2, and the grade of the service quality of the Host in DC by it is high on earth Host1, Host2 are ordered as, therefore, according to the mapping method provided in the embodiment of the present application, then for by VNFCB1Preferential mapping To Host1, next to VNFCB1Adjacent VNFC, that is, VNFCA1And VNFCB2Mapped, and preferentially by the first priority more High VNFCA1It maps on Host1, if at this point, the resource on Host1 has been in an emergency, i.e., can not continue VNFCB2It maps to When on Host1, then by VNFCB2Map to service quality etc. on the high Host2 of levels.It is next needed based on above-mentioned mapping relations Link that will be between VNFC is mapped, due to by VNFCB1And VNFCA1It is mapped on same Host1, therefore VNFC links VLA1-B1It can then be rejected, not need to be mapped again, only need to carry out VL at this timeB1-B2Link maps be Can, and due to VNFCB1And VNFCB2It is mapped on Host1 and Host2 respectively, therefore, VLB1-B2Need to be mapped in Host1 and Host chains road between Host2.
