具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的实施例仅用以解释本申请，并不用于限定本申请。

本申请提供了一种网络切片资源编排方法、网络设备及计算机可读存储介质，通过获取网络端口的网络资源需求模型，能够获知业务网元的对外连接端口的网络资源参数要求，进而根据该网络资源参数要求确定业务网元的对外网络资源需求，并基于对外网络资源需求生成适配度更佳的针对网络切片的第一资源编排策略，相比于相关技术，基于业务网元的对外连接端口的网络资源需求模型而生成第一资源编排策略，良好体现了对外连接端口的网络资源需求模型对于网络切片资源编排的影响，可以降低因人工识别编排模型而带来的编排误差，提高网络切片资源编排的准确率，进而提升网络自动化开通运维的效率。
下面结合附图，对本申请实施例作进一步阐述。
如图1所示，图1是本申请一个实施例提供的用于执行网络切片资源编排方法的网络系统100的示意图。
在图1的示例中，该网络系统100包括但不限于：第一切片管理装置110和第二切片管理装置120，其中，第一切片管理装置110和第二切片管理装置120相连接，两者之间可以进行不同程度的信息交互，通过两者的配合能够实现网络切片资源编排，在一些实施例中，可以用于通用的端到端网络切片资源编排管理，也可以应用于某个子域的切片子网管理等。
需要说明的是，在一些应用情况下，该网络系统100也可作为非切片场景的通用配置功能管理架构，应用于网元开局配置、策略配置等场景。
在一实施例中，参照图2，图2是本申请另一个实施例提供的网络系统100的示意图，其中，第一切片管理装置110可以但不限于为NSMF，NSMF作为提供网络切片配置信息制作、管理和下发的功能模块，能够实现网络切片资源编排功能，负责端到端网络切片无线接入网、核心网及传输网的资源编排配置。
在一实施例中，参照图2，第一切片管理装置110可以但不限于为NSSMF，在这种情况下，NSSMF能够接收来自NSMF的相关编排信息，进而根据获取到的相关编排信息配合第二切片管理装置120，以实现NSSMF 所属切片子网的资源编排配置。
在一实施例中，参照图2，第二切片管理装置120可以但不限于为NFVO，NFVO能够接收来自NSMF或NSSMF的相关编排信息，进而根据获取到的相关编排信息负责整体网络业务或NSSMF所属切片子网的资源编排配置。
在一实施例中，第一切片管理装置110和第二切片管理装置120具有良好的运维特性，例如，在切片网络运维过程中，NSMF或NSSMF可以定期地向NFVO查询网络切片数据，查询的数据可以但不限于包括业务网元的编排模板、业务网元的实际网络资源量以及对外连接端口的实际网络资源量等，可以看出，通过第一切片管理装置110和第二切片管理装置120之间的信息交互，可以进一步获知切片网络的实际运行状态，以便于对切片网络运行状态进行实时调节。
可以理解地是，网络切片内的业务网元的类型可以为多种，业务网元的类型对于切片业务配置不会产生过于明显地影响，因此本实施例并未限制业务网元的类型，为了描述方便，以下各实施例主要以业务网元为物理网络功能(Physical Network Function，PNF)网元或虚拟网络功能(Virtual Network Function，VNF)网元的情况进行说明，但这并不属于对业务网元的类型进行限制。
在一实施例中，每个业务网元存在与之对应的网络功能模板，网络功能模板可以为业务网元集成相应的功能条件，描述业务网元的计算资源、存储资源需求等，例如，PNF网元对应的网络功能模板为物理网络功能模板(Physical Network Function Descriptor,PNFD)，VNF网元对应的网络功能模板为虚拟网络功能模板(Virtual Network Function Descriptor,VNFD)。
需要强调的是，对应于本实施例给出的网络系统100，在VNFD、PNFD等网络功能模型中，新增网络资源需求模型的定义，网络资源需求模型用于表征网络端口的网络资源参数要求，网络端口即为网络切片内的业务网元的对外连接端口，在一些实施例中，针对业务网元的不同对外连接端口，可以提供区分不同网络场景的多个编排模板，每个编排模板中包含一个或者多个原子编排模板，用户可以根据需求的业务场景直接使用编排模板，或者，业务网元也可以仅提供多个原子编排模板，由用户根据业务需求以及原子模板的适用场景，自行挑选原子编排模板进行组合，其中，每个原子编排模板包括如下类型中的至少一种:
服务质量需求模型，用于表征网络端口的带宽要求，例如网络带宽等；或
时延需求模型，用于表征网络端口的时延要求，例如网络延迟时间等；或
抖动需求模型，用于表征网络端口的抖动要求，例如丢包率等。
其中，在应用场景下，PNFD和VNFD均可以发布在NFVO上，且均可以被NFVO和NSSMF查询得到，例如，关于NFVO的查询，NFVO可以设计并发布网络服务描述(Network Service Descriptor,NSD)，NSD可以进一步地引用VNFD(即对应的业务网元为VNF网元)，由于VNFD携带有网络资源需求模型，因此通过NSD也可以解析得到网络资源需求模型，因此，NSMF可以通过NSSMF向NFVO发送查询VNFD或NSD的相关查询信息，则能够解析得到网络资源需求模型，进而能够基于网络资源需求模型配合NFVO实现对网络切片资源的编排管理。
可以理解地是，以上关于原子编排模板的类型描述只是作为示例以说明其工作原理，并未对其类型进行限制，本领域技术人员可以根据实际应用场景而设计原子编排模板的类型，这在本实施例中并未限制。
在一实施例中，在NSMF或NSSMF中，当设计网络切片资源编排方式时，可以将从NFVO查询得到的VNFD、PNFD或NSD中的网络资源需求模型，作为网络切片资源编排方式设计的依据，从而得到满足要求的编排策略。同时，针对所采集的不同网元类型的各种网络资源需求模型，可形成模型存储库以收集各种网络资源需求模型，当业务网元的编排模板版本号发生变更时，换言之，对应的网络资源需求模型也随之发生变化，NSMF或NSSMF可通过更新的模板与原来的模板的比对而自动识别差异，进而实现自动更新模型存储库，以此可见，通过设置模型存储库能够更加有效方便地管理不同网元类型的各种网络资源需求模型，以便能够更加可靠地利用网络资源需求模型实现网络切片资源编排管理。
在另一实施例中，第一切片管理装置110和第二切片管理装置120中均可以包括但不限于有编排UI，编排UI能够提供用户管理界面，用于管理编排模板和交互数据，方便运维人员进行人工审核和调整。
网络系统100中的第一切片管理装置110和第二切片管理装置120均可以分别包括有存储器和处理器，其中，存储器和处理器可以通过总线或者其他方式连接。
存储器作为一种非暂态计算机可读存储介质，可用于存储非暂态软件程序以及非暂态性计算机可执行程序。此外，存储器可以包括高速随机存取存储器，还可以包括非暂态存储器，例如至少一个磁盘存储器件、闪存器件、或其他非暂态固态存储器件。在一些实施方式中，存储器在一些实施例中包括相对于处理器远程设置的存储器，这些远程存储器可以通过网络连接至该处理器。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
本申请实施例描述的网络系统100以及应用场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域技术人员可知，随着网络系统100的演变和新应用场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本领域技术人员可以理解的是，图1和图2中示出的网络系统100并不构成对本申请实施例的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
在图1和图2所示的网络系统100中，第一切片管理装置110和第二切片管理装置120可以分别调用其储存的网络切片资源编排程序，以执行网络切片资源编排方法。
基于上述网络系统100的结构，提出本申请的网络切片资源编排方法的各个实施例。
如图3所示，图3是本申请一个实施例提供的网络切片资源编排方法的流程图，可以但不限于应用于如图1和图2实施例所示的网络系统，该网络切片资源编排方法包括但不限于步骤S100至S300。
步骤S100：获取网络端口的网络资源需求模型，网络资源需求模型用于表征网络端口的网络资源参数要求，网络端口为网络切片内的业务网元的对外连接端口。
在一实施例中，通过获取网络端口的网络资源需求模型，能够获知业务网元的对外连接端口的网络资源参数要求，从而能够在配置对外连接端口的网络资源时，更多地考虑到对外连接端口的网络资源参数要求影响，并且在后续步骤中可以基于网络资源需求模型实现进一步地网络切片资源编排。
在一实施例中，网络资源需求模型包括如下类型中的至少一种:
服务质量需求模型，用于表征网络端口的带宽要求；或
时延需求模型，用于表征网络端口的时延要求；或
抖动需求模型，用于表征网络端口的抖动要求。
其中，各个模型之间可以是相互联系的，例如，网络端口的带宽可以依据时延而进行设置，在一些实施例中取决于应用场景下的需求。
在一实施例中，网络端口的数量可以不限制，由于不同的网络端口实现的功能可能不同，因此针对各个网络端口的网络资源需求模型可以按需选择，这在本实施例中并未限制。
在图4的示例中，步骤S100包括但不限于步骤S110至S120。
步骤S110：获取对应于业务网元的网元配置模型；
步骤S120：从网元配置模型中得到网络端口的网络资源需求模型。
在一实施例中，由于网元配置模型中携带有网络资源需求模型，因此通过获取网元配置模型即可确定网络端口的网络资源需求模型，该方式可以确保网络资源需求模型能够稳定地被加载，避免出现无法准确地确定网络资源需求模型的情况，可以理解地是，实现步骤S110和S120的方式有多种，本领域技术人员可以根据实际场景相应选择获取方式，这在本实施例中并未限制。
步骤S200：根据网络资源需求模型确定业务网元的对外网络资源需求。
在一实施例中，由于业务网元的对外连接端口的网络资源需求模型已经确定，因此针对业务网元而言，其对外所需的相应网络资源也可以确定，即进一步确定业务网元的对外网络资源需求，以便于根据业务网元的对外网络资源需求以进一步实现网络切片资源编排。
在图5的示例中，步骤S200包括但不限于步骤S210至S220。
步骤S210：获取网络切片的网络资源需求；
步骤S220：根据网络资源需求模型和预置的映射规则，将网络切片的网络资源需求转换为业务网元的对外网络资源需求。
在一实施例中，由于网络切片的网络资源需求包括网络切片的各种各样的资源需求，因此可以考虑将网络切片的网络资源需求统一地转化为一类需求来进行考虑，这样在后续解析网络切片的网络资源需求时将会更加简单方便，并且由于根据网络资源需求模型和预置的映射规则，将网络切片的网络资源需求转换为业务网元的对外网络资源需求，从而可以通过业务网元的对外网络资源需求来表征网络切片的网络资源需求，进而基于对外网络资源需求实现针对网络切片的资源编排。
在一实施例中，映射规则用于表征网络切片的网络资源需求与业务网元的对外网络资源需求之间的映射关系，可以通过网络切片的网络资源需求而直接地确定，也可以根据应用场景的不同而由本领域技术人员自行设置。
步骤S300：根据对外网络资源需求生成第一资源编排策略，第一资源编排策略用于对网络切片进行资源编排。
在一实施例中，通过获取网络端口的网络资源需求模型，能够获知业务网元的对外连接端口的网络资源参数要求，进而根据该网络资源参数要求确定业务网元的对外网络资源需求，并基于对外网络资源需求生成适配度更佳的针对网络切片的第一资源编排策略，相比于相关技术，基于业务网元的对外连接端口的网络资源需求模型而生成第一资源编排策略，良好体现了对外连接端口的网络资源需求模型对于网络切片资源编排的影响，可以降低因人工识别编排模型而带来的编排误差，提高网络切片资源编排的准确率，进而提升网络自动化开通运维的效率。
在图6的示例中，步骤S300包括但不限于步骤S310至S320。
步骤S310：根据对外网络资源需求确定业务网元需求的第一网络资源；
步骤S320：根据第一网络资源生成第一资源编排策略。
在一实施例中，通过对外网络资源需求确定业务网元需求的第一网络资源，即可确定需要为业务网元编排分配的网络资源，进而根据所需编排分配的网络资源对应生成第一资源编排策略，即可实现稳定高效地对网络切片所需求的资源进行编排。
在一实施例中，第一网络资源可以包括但不限于有：业务网元所需的对外网络资源，该部分资源用于支持业务网元的对外连接端口的资源需求，或者，在某些情况下，当对外连接端口的资源需求无法满足业务网元需求，则第一网络资源还可以包括但不限于有：业务网元的外部虚拟网络链接(Virtual Link,VL)，即通过外部VL来弥补业务网元的需求，使得业务网元所需的对外网络资源与外部VL能够配合满足业务网元所需的网络资源，可以理解地是，在一些情况下，若外部VL能够直接地满足业务网元所需的网络资源，则可以不必编排分配业务网元所需的对外网络资源。
在图7的示例中，步骤S300之后还包括但不限于步骤S400。
步骤S400：当第一网络资源未匹配对外网络资源需求，将第一资源编排策略调节为第二资源编排策略。
在一实施例中，在网络运维过程中，若检测到第一网络资源不能满足对外网络资源需求，则说明此时的第一资源编排策略不符合业务网元的实际需求，换言之，此时的网络切片编排方式无法满足网络切片的网络资源需求，因此可以考虑将第一资源编排策略调节为第二资源编排策略，以满足网络切片的网络资源需求。
在图8的示例中，在第一网络资源包括网络端口需求的第二网络资源的情况下，步骤S400包括但不限于步骤S410至S430。
步骤S410：获取网络端口的当前网络资源；
步骤S420：在当前网络资源包括第二网络资源的情况下，根据第一网络资源和对外网络资源需求生成网络资源调节需求；
步骤S430：根据网络资源调节需求将第一资源编排策略调节为第二资源编排策略。
在一实施例中，通过获取当前网络资源并确定当前网络资源已经包括网络端口需求的第二网络资源，则说明业务网元的对外连接端口的对应网络资源能够符合对外网络资源需求，那么考虑对外网络资源需求本身无法满足的情况，因此可以进一步通过第一网络资源和对外网络资源需求生成新的网络资源调节需求，进而据此确定变更后的第二资源编排策略。
在一实施例中，网络端口的当前网络资源的采集时机可以根据实际情况确定，考虑到实际应用场景，可以在执行第一资源编排策略之后一段时间后来进行采集，所获取到的采集结果将会相对准确，这在本实施例中并未限制。
在图9的示例中，步骤S430包括但不限于步骤S431至S432。
步骤S431：根据网络资源调节需求确定业务网元需求的第三网络资源；
步骤S432：根据第一网络资源和第三网络资源，将第一资源编排策略调节为第二资源编排策略。
在一实施例中，通过变更后的网络资源调节需求可以重新确定业务网元所需弥补的第三网络资源，进而能够基于之前确定的第一网络资源和当前确定的第三网络资源，最终确定业务网元需求的网络资源，可以看出，采用弥补第三网络资源的方式，可以更加准确地调节资源编排策略，避免出现无法满足业务网元的需求的网络资源的情况。
如图10所示，图10是本申请另一个实施例提供的网络切片资源编排方法的流程图，可以但不限于应用于如图1和图2实施例所示的网络系统，该网络切片资源编排方法包括但不限于步骤S500至S800。

步骤S700：第二网络设备接收由第一网络设备发送的对外网络资源需求；
步骤S800：第二网络设备根据对外网络资源需求生成第一资源编排策略，第一资源编排策略用于对网络切片进行资源编排。
在一实施例中，第一网络设备通过获取网络端口的网络资源需求模型，能够获知业务网元的对外连接端口的网络资源参数要求，进而第一网络设备根据该网络资源参数要求确定业务网元的对外网络资源需求，并向第二网络设备发送对外网络资源需求，因此第二网络设备能够基于对外网络资源需求生成适配度更佳的针对网络切片的第一资源编排策略，相比于相关技术，基于业务网元的对外连接端口的网络资源需求模型而生成第一资源编排策略，良好体现了对外连接端口的网络资源需求模型对于网络切片资源编排的影响，可以降低因人工识别编排模型而带来的编排误差，提高网络切片资源编排的准确率，进而提升网络自动化开通运维的效率。
在一实施例中，网络资源需求模型包括如下类型中的至少一种:
服务质量需求模型，用于表征网络端口的带宽要求；或
时延需求模型，用于表征网络端口的时延要求；或
抖动需求模型，用于表征网络端口的抖动要求。
其中，各个模型之间可以是相互联系的，例如，网络端口的带宽可以依据时延而进行设置，在一些实施例中取决于应用场景下的需求。
在图11的示例中，步骤S500包括但不限于步骤S510至S520。
步骤S510：第一网络设备获取对应于业务网元的网元配置模型；
步骤S520：第一网络设备从网元配置模型中得到网络端口的网络资源需求模型。

示例一：
如图12所示，以NSSMF从NFVO查询网络资源需求模型为例。

在图13的示例中，步骤S600包括但不限于步骤S610至S620。
步骤S610：第一网络设备获取网络切片的网络资源需求；
步骤S620：第一网络设备根据网络资源需求模型和预置的映射规则，将网络切片的网络资源需求转换为业务网元的对外网络资源需求。
在一实施例中，由于网络切片的网络资源需求包括网络切片的各种各样的资源需求，因此可以考虑将网络切片的网络资源需求统一地转化为一类需求来进行考虑，这样在后续解析网络切片的网络资源需求时将会更加简单方便，并且由于根据网络资源需求模型和预置的映射规则，将网络切片的网络资源需求转换为业务网元的对外网络资源需求，从而可以通过业务网元的对外网络资源需求来表征网络切片的网络资源需求，进而基于对外网络资源需求实现针对网络切片的资源编排。
在图14的示例中，步骤S800包括但不限于步骤S810至S820。
步骤S810：第二网络设备根据对外网络资源需求确定业务网元需求的第一网络资源；
步骤S820：第二网络设备根据第一网络资源生成第一资源编排策略。
在一实施例中，第二网络设备通过对外网络资源需求确定业务网元需求的第一网络资源，即可确定需要为业务网元编排分配的网络资源，进而根据所需编排分配的网络资源对应生成第一资源编排策略，即可实现稳定高效地对网络切片所需求的资源进行编排。

在一实施例中，在网络运维过程中，若检测到第一网络资源不能满足对外网络资源需求，则说明此时的第一资源编排策略不符合业务网元的实际需求，换言之，此时的网络切片编排方式无法满足网络切片的网络资源需求，因此可以考虑将第一资源编排策略调节为第二资源编排策略，以满足网络切片的网络资源需求。

在一实施例中，通过获取当前网络资源并确定当前网络资源已经包括网络端口需求的第二网络资源，则说明业务网元的对外连接端口的对应网络资源能够符合对外网络资源需求，那么考虑对外网络资源需求本身无法满足的情况，因此可以进一步通过第一网络资源和对外网络资源需求生成新的网络资源调节需求，进而据此确定变更后的第二资源编排策略。
示例四:
