Containers use operating system isolation technologies, such as CGroup and NameSpace under Linux, to isolate different processes. Container technology is different from hardware virtualization technology (hypervisor) technology, it has no virtual hardware, and there is no operating system inside, only processes. It is precisely because of this feature of container technology that containers are lighter than virtual machines and more convenient to manage.

具体实施方式
网络功能虚拟化(network function virtualization,NFV)是指电信网络运营商借鉴了信息技术领域的虚拟化技术,在通用的服务器、交换机和存储器中将部分电信网络功能的实现进行软件和硬件解耦,从而实现网络服务(network service,NS)快速、高效部署,同时达到节省投资成本和运营成本。虚拟化技术将电信网络功能以软件方式实现,并能在通用的服务器硬件上运行,可以根据需要进行迁移、实例化、部署在网络的不同物理位置,并且不需要安装新设备。
NFV的标准化工作主要集中在网路服务、虚拟网络功能和虚拟资源的管理和编排,由欧洲通信标准协会下的NFV接口与架构组工作组完成MANO框架内的功能定义工作,其功能架构如图1所示。
NFVO用于实现网络服务描述符(network service descriptor,NSD),虚拟网络功能转发图(VNF forwarding graph,VNFFG)的管理和处理,网络服务生命周期的管理,以及与VNFM配合实现VNF的生命周期管理和虚拟资源的管理功能。
VNFM用于实现VNF的生命周期管理,包括VNF的实例化、VNF实例的弹性伸缩(包括扩容Scaling out/up和缩容Scaling in/down)、VNF实例的治愈(healing)以及VNF实例的终止。
虚拟基础设施管理器(virtualised infrastructure manager,VIM)用于负责基础设施层硬件资源,虚拟化资源的管理(包括预留和分配),虚拟资源状态的监控和故障上报,面向上层应用提供虚拟化资源池。
运营和商务支撑系统(operations and business support systems,OSS/BSS)指运营商的运行维护系统OSS/BSS。
网元管理器(element manager,EM)对VNF进行传统的故障管理(fault management)、配置管理(configuration management)、用户管理(account management)、性能管理(performance management)和安全管理(security management)的功能,其中,故障管理、配置管理、用户管理、性能管理和安全管理简称FCAPS。
虚拟化网络功能(virtualized network function,VNF)对应于传统非虚拟化网络中的物理网络功能(physical network function,PNF),如虚拟化的EPC节点(包括移动管理实体(mobility management entity,MME),服务网关(serving gateway,SGW),分组数据网关(packet data network,PGW)等)。网络功能的功能性行为和状态与虚拟化与否无关,NFV技术需求希望VNF和PNF拥有相同的功能性行为和外部接口。
VNF由一个或多个更低功能级别的VNF组件(VNF Component,VNFC)组成。因此,一个VNF可以部署在多个虚拟机(virtual machine,VM)上,每个VM承载一个VNFC的功能,VNF也可以部署在一个VM上。
NFV基础架构(NFV infrastructure,NFVI)由硬件资源和虚拟资源以及虚拟化层组成。从VNF的角度来说,虚拟化层和硬件资源结合起来是一个能够提供所需虚拟资源的完整实体。
容器是一种操作系统级别的虚拟化技术。容器是容器即服务(container as a service,CaaS)的简称,CaaS是一种特定类型的平台即服务(platform as a service,PaaS)服务。容器通过操作系统隔离技术,如Linux下的CGroup和NameSpace,将不同的进程隔离开。容器技术不同于硬件虚拟化(hypervisor)技术,它没有虚拟硬件,其内部也没有操作系统,只有进程。正是由于容器技术的这个特点,使得容器相比虚拟机更轻量,管理也更方便。为了方便管理,在容器的运行态,定义了一组公共的管理操作,例如:启动、停止、暂停和删除等,对容器进行统一的生命周期管理。
ETSI NFV标准中容器服务的部署用例如图2所示,其中,容器基础设施服务(Container Infrastructure Service)也可以称为容器服务,容器基础设施服务管理(Container Infrastructure Service Management)也可以称为容器服务管理。在图2的部署用例中,容器服务和容器服务管理都位于PaaS层,或者可以独立于PaaS层之外成为服务PaaS层的基础设施服务层。容器服务可以被VNF直接调用,也可以被VNF所调用的公共服务或专有服务(例如:PaaS服务)所调用。容器服务的注册和发现功能被置于容器基础设施服务管理中,标准化的基本目标是将容器服务管理的功能融合到NFV MANO架构功能中,实现NFV MANO对容器化VNF进行生命周期管理时对该VNF所调用的容器服务进行相应的生命周期管理的功能。
上文描述了NFV MANO的标准架构和容器服务部署用例,下面对本申请实施例提供的容器化VNF的部署方法进行描述。
为了适应容器化VNF弹性部署的需求,本申请实施例提供了一种容器化VNF的部署方法,通过在容器化VNF的虚拟网络功能描述符文件(VNF descriptor,VNFD)中增加对不同VNF组件的部署模板(Virtual Deployment Unit,VDU)进行差异化描述,来实现VNFM对容器化VNF的组成部分进行差异化处理的部署,以增强容器化VNF部署的弹性。
在本申请的一个实施例中,如图3所示,将容器化VNF分成两部分:容器运行时环境和容器化VNFC,VNF这两个组成部分(分别作为不同的VNF组件)都通过使用VNFD中的VDU定义进行实例化,但在各自的VDU中有不同的内容定义。容器运行时环境(container runtime environment,CRE)是基于在线获取的镜像(image)来创建和运行容器的程序,例如Kubernetes系统中Kubelet。其中,镜像是一系列软件文件按照一定的格式制作的单一文件,类似于ZIP包文件,可以封装软件运行所有的相关信息。容器化VNF可以部署在多个容器运行时环境中,每个容器运行时环境都有相应的容器管理器(CaaS Mgt)进行管理。
容器化VNFC中封装了容器化VNFC镜像,并在特定的容器运行时环境中,由对应的容器管理器(CaaS Mgt)为容器化VNFC镜像分配相应的计算资源、存储资源和网络资源,最终完成VNFC的实例化。
其中,容器化VNFC可以称为容器应用(container application或application container),容器应用运行在容器运行时环境上,容器化VNFC镜像构成容器镜像。容器运行时环境的镜像加载到虚拟机中是VM镜像的一部分。
通过该实施例进行容器化VNF部署的前提条件是:在容器化VNF的VNFD中分别针对容器进行时环境和容器化VNFC定义内容有差别的VDU。
在容器运行时环境对应的VDU定义中,增强了属性为软件镜像描述swImageDesc和NFVI约束的描述。其中,swImageDesc指定加载到虚拟机的容器运行时环境的镜像,作为虚拟机(VM)镜像的一部分。NFVI约束指定对加载容器运行时环境的VM的约束,例如:VM的位置、容量等。
在容器化VNFC对应的VDU定义中,增强了属性为软件镜像描述swImageDesc和容器运行时环境约束(CRE constraint)的描述。其中,swImageDesc指定容器化VNFC的镜像(作为容器镜像)。容器运行时环境约束指定对使用该VDU部署的VNFC实例容器化运行时环境CRE的约束,例如:在指定的CRE上部署VNFC实例。
在该实施例中,将容器化VNF分成两部分:容器运行时环境CRE和容器化VNFC,可以理解为将容器化VNF分为两种不同的VNFC,即CRE和容器化VNFC,也就是将CRE也看作是一种VNFC。在这种情况下,容器化VNF部署的方法如图4所示。
需要说明的是,在下文中的“第一”和“第二”只是为了区分消息或信息,对消息或信息的本身不作限定。
图4是本申请实施例提供的一种容器化VNF的部署方法示意图。如图4所示,该方法可以包括以下步骤:
S101,VNFM接收NFVO发送的VNF实例化请求消息。
VNFM接收由NFVO发送的VNF实例化请求消息,以请求容器化VNF的部署。
可选地,在一个实施例中,该VNF实例化请求消息包括容器化VNF的描述符文件VNFD的标识,以便于后续VNFM从该VNF描述符文件获取容器化VNFC与CRE的关系信息。
可选地,在另一个实施例中,VNF实例化请求消息包括容器化VNF的部署模板(deployment flavor)或者实例化等级标识中的至少一项,以便于后续VNFM获取容器化VNFC与CRE的关系信息。
S102,VNFM根据VNF实例化请求消息获取容器化VNFC与CRE的关系信息,并根据关系信息确定容器化VNF部署的目标CRE。
在一个实施例中,当VNF实例化请求消息中包括容器化VNF的VNFD的标识时,VNFM根据VNFD的标识确定VNFD,并从VNFD中获取容器化VNFC与CRE的关系信息。
在另一个实施例中,当VNF实例化请求消息中包括容器化VNF的部署模板标识或者实例化等级标识中的至少一项时,VNFM根据VNFM标识或者实例化等级标识中的至少一项获取容器化VNFC与CRE的关系信息。
其中,容器化VNFC与CRE的关系信息包括容器化VNFC可以部署在哪些CRE上的信息,换句话讲,指定容器化VNFC可以部署在哪些指定的CRE的信息,例如容器化VNFC可以部署在Kubernetes,OpenShift,Azure等CRE上。
可选地,在一个实施例中,容器化VNFC可以部署在一个或者多个CRE上。
S103,VNFM实例化目标CRE,并为实例化的目标CRE分配由容器管理器管理的第一虚拟机资源。
在VNFM确定目标CRE后,VNFM向NFVO发送虚拟资源分配请求消息,并通过NFVO从VIM获取为实例化目标CRE分配的虚拟机资源,即第二虚拟机资源,包括计算资源,存储资源和网络资源。VNFM从NFVO接收为实例化目标CRE分配的第二虚拟机资源的信息,第二虚拟机资源的信息包括虚拟机的标识。VNFM通过NFVO向VIM发起软件镜像加载请求,将所确定的目标CRE的镜像加载到分配的虚拟机上。VNFM完成目标CRE实例化的相关配置,最终完成目标CRE的实例化。
完成目标CRE实例化后,VNFM为实例化的目标CRE分配由容器管理器(CaaS Mgt)管理的第一虚拟机资源,并将第一虚拟机资源的信息发送给容器管理器(CaaS Mgt)。
S104,VNFM向容器管理器发送第一虚拟机资源的信息。该第一虚拟机资源的信息可以包括分配给容器化VNFC的至少一个虚拟机的标识。
S105,VNFM向容器管理器发送软件镜像加载请求消息。
软件加载请求消息用于容器管理器将容器化VNFC的镜像加载到容器单元内,并将容器单元编排到容器管理器管理的第一虚拟机资源上,以进一步完成容器化VNFC的实例化。其中,容器单元是承载所述容器化VNFC镜像运行的容器计算资源,即:将VNFC的镜像作为容器镜像加载到一组容器单元(作为计算资源)上,这些容器单元是对其所处的节点资源(例如:虚拟机VM)进行切分的更小颗粒的计算资源。容器单元可以映射为Kubernetes对象“容器组”(Pod)。
S106,容器管理器将部署在该实例化的目标CRE上的容器化VNFC的镜像加载到第一虚拟机资源上。
也就是将容器化VNFC镜像加载在第一虚拟机资源的信息对应的虚拟机上。
S107,VNFM向容器管理器发送容器化VNFC实例化的请求消息。
容器化VNFC实例化的请求消息用于容器管理器完成容器化VNFC的实例化。
S108,容器管理器实例化容器化VNFC。
在该实施例中,由VNFM触发容器化VNFC的实例化,由容器管理器执行完成容器化VNFC的实例化。容器管理器完成容器化VNFC的实例化后,向VNFM返回容器化VNFC实例化的应答消息。
可选地,在该实施例中,如图4所示,该方法还可以包括:
S109,VNFM向NFVO发送VNF实例化的应答消息。
可选地,在该实施例中,触发VNFM进行容器化VNF部署的还有可能是EM,换句话讲,VNFM接收到的VNF实例化请求消息可以是由NFVO发送过来的,也有可能是EM发送过来的。当VNFM接收到的VNF实例化请求消息是由EM发送的时,那么在完成容器化VNF部署后,VNFM向EM发送VNF实例化的应答消息,通知EM完成容器化VNF的部署。
采用该实施例提供的容器化VNF的部署方法,通过将容器化VNF中的CRE和容器化VNFC看作不同的VNFC,并在容器化VNF的VNFD中增加CRE和容器化VNFC的关系信息,以对不同的VNFC部署进行区分,增强了容器化VNF部署的弹性,即容器化VNF部署的灵活性。同时提高了容器化VNF部署的效率。
本申请实施例还提供了一种容器化VNF的内部结构,如图5所示。图5所示的容器化VNF也是将容器化VNF分成两部分:容器运行时环境CRE和容器化VNFC,但与图3不同的是,图5中,CRE实例预先部署在网络功能虚拟化基础设施(network function virtualization infrastructure,NFVI)中,当接收到容器化VNF实例化请求消息时直接进行容器化VNFC的实例化,以完成容器化VNF的实例化过程,其具体过程如图6所示。
图6是本申请实施例提供的另一种容器化VNF的部署方法流程示意图。该方法包括以下步骤:
S201,VNFM接收NFVO发送的VNF实例化请求消息。
VNFM接收由NFVO发送的VNF实例化请求消息,以请求容器化VNF的部署。
S202,VNFM根据VNF实例化请求消息获取容器化VNFC与CRE的关系信息,并根据关系信息确定容器化VNF部署的目标CRE。
S203,VNFM将分配给实例化的目标CRE的第一虚拟机资源的信息发送给目标CRE对应的容器管理器,其中,第一虚拟机资源由目标CRE对应的容器管理器管理。
S204,VNFM向容器管理器发送软件镜像加载请求消息。
S205,容器管理器将部署在该实例化的目标CRE上的容器化VNFC的镜像加载到第一虚拟机资源上。
S206,VNFM向容器管理器发送容器化VNFC实例化的请求消息,以请求容器管理器完成容器化VNFC的实例化。
S207,容器管理器实例化容器化VNFC,并向VNFM发送容器化VNFC实例化的应答消息。
可选地,在该实施例中,如图4所示,该方法还可以包括:
S208,VNFM向NFVO发送VNF实例化的应答消息,以通知NFVO以完成容器化VNF的部署。
在该实施例中容器化VNF部署的过程中,因为预先将CRE部署在NFVI中,因此在图5中没有对应图4中S103实例化目标CRE的步骤,除此外,图5中的其他的步骤:S201至S208与图4中的S101、S102、S104至S108的描述相同,为简洁描述,在此不再赘述。
本申请实施例还提供了另一种容器化VNF的部署方法,如图7所示。该容器化VNF的部署方法与图4的区别在于,在该实施例中,将容器化VNF中的CRE和容器化VNFC看作是两类不同的VNF,对这两类VNF的VNFD分别进行定义,在VNFD之间指定容器化VNFC的部署对容器化运行时环境的依赖关系,即容器化VNFC与CRE的关系信息。
在容器运行时环境对应的VNFD定义中,增强了属性为swImageDesc的功能描述,其中,swImageDesc指定VNF使用软件镜像(包括容器运行时环境的镜像)的描述,这些软件镜像加载到虚拟机,称为虚拟机(VM)镜像。
在容器化VNFC对应的VNFD定义中,新增了属性为DependentCreDescriptor的功能描述,DependentCreDescriptor指定对使用该VNFD部署的VNFC实例容器进行时环境CRE的约束,例如:在指定的CRE上部署容器化VNFC实例。
此外,容器化运行时环境的部署与容器化VNFC的部署相互独立,换句话讲,容器化运行时环境的部署与容器化VNFC的部署不相关,其中,容器化运行时环境的部署包括CRE镜像加载和CRE实例化。而且VNFM不再参与分配虚拟机资源的过程,这个过程改由NFVO来完成。这里的虚拟机资源是为部署容器化VNFC指定的目标CRE分配的。NFVO分配的虚拟机资源由容器管理器(CaaS Mgt)进行管理。
图7是本申请实施例提供的另一种容器化VNF的部署方法流程示意图。如图7所示,该方法可以包括以下步骤:
S301,NFVO向VNFM发送第一VNF实例化请求消息。

可选地,在另一个实施例中,第一VNF实例化请求消息包括容器化VNF的部署模板标识或者实例化等级标识中的至少一项,以便于后续VNFM接收到第一VNF实例化请求消息后,根据部署模板标识或者实例化等级标识中的至少一项获取容器化VNFC与CRE的关系信息。
S302,VNFM根据第一VNF实例化请求消息获取容器化VNFC与CRE的关系信息,并根据关系信息确定容器化VNF部署的目标CRE。
在一个实施例中,当第一VNF实例化请求消息中包括容器化VNF的VNFD标识时,VNFM从VNFD标识对应的VNFD中读取容器化VNFC与CRE的关系信息,进一步根据VNFC与CRE的对应关系确定容器化VNF部署的目标CRE。
在另一个实施例中,当VNF实例化请求消息中包括容器化VNF的部署模板标识或者实例化等级标识中的至少一项时,VNFM根据部署模板标识或者实例化等级标识中的至少一项获取容器化VNFC与CRE的关系信息。
其中,容器化VNFC与CRE的关系信息可以是容器化VNFC部署在指定的一个或者多个CRE上,换句话讲,是特定的容器化VNFC可以部署在指定的一个或多个CRE上,例如容器化VNFC可以部署在Kubernetes,OpenShift,Azure等CRE上。
当VNFM获取到容器化VNFC与CRE的关系信息时,根据该关系信息确定容器化VNFC所能部署在的目标CRE。
S303,NFVO获取为实例化容器化VNFC分配由容器管理器管理(CaaS Mgt)的第一虚拟机资源的信息。
NFVO向VIM发送虚拟资源分配请求,请求VIM为实例化的容器化VNFC分配相应的虚拟机资源,包括计算资源,存储资源,网络资源,以及分配给容器化VNFC的至少一个虚拟机的标识;从VIM获取虚拟机资源的信息。这里讲的虚拟机资源的信息即第一虚拟机资源的信息。
S304,NFVO向VNFM发送第一虚拟机资源的信息。
其中,第一虚拟机资源的信息包括虚拟机标识。以用于VNFM接收到第一虚拟机资源的信息后,将第一虚拟机的资源信息发送给容器管理器。换句话讲,以用于VNFM接收到虚拟机的标识后,将虚拟机的标识发送给容器管理器,以便于后续根据虚拟机的标识寻址对应的虚拟机资源。
S305,VNFM向容器管理器发送第一虚拟机资源的信息。
S306,VNFM向容器管理器发送第一软件镜像加载请求消息。
当VNFM接收到NFVO发送的第一虚拟机资源的信息时,向容器管理器发送第一软件镜像加载请求消息,以请求将部署在实例化的目标CRE上的容器化VNFC镜像加载到容器单元内,并将容器单元编排到容器管理器管理的第一虚拟机资源上,换句话讲,将容器单元编排到虚拟机的标识对应的虚拟机上。其中,容器单元是承载容器化VNFC的镜像运行的容器计算资源。
S307,容器管理器将部署在实例化目标CRE上的容器化VNFC的镜像加载到虚拟机上。
S308,VNFM向容器管理器发送容器化VNFC实例化的请求消息。
容器化VNFC实例化的请求消息用于容器管理器完成容器化VNFC的实例化。
S309,容器管理器实例化容器化VNFC。
在该实施例中,由VNFM触发容器化VNFC的实例化,由容器管理器执行完成容器化VNFC的实例化。容器管理器完成容器化VNFC的实例化后,向VNFM返回容器化VNFC实例化的应答消息。
可选地,在该实施例中,如图7所示,该方法还包括:
S310,VNFM向NFVO发送VNF实例化的应答消息,以通知NFVO完成容器化VNF的部署。
可选地,在该实施例中,触发VNFM进行容器化VNF部署的还可以是EM,换句话讲,EM向VNFM发送VNF实例化请求消息。当VNFM接收到VNF实例化请求消息时,执行S320至S370的操作,完成S370中容器化VNFC的实例化后,VNFM向EM发送VNF实例化的应答消息,以通知EM完成容器化VNF的部署。
采用该实施例提供的容器化VNF的部署方法,通过将容器化VNF中的CRE和容器化VNFC看作不同类型的VNF,并在容器化VNFC的VNFD中增加CRE对应的VNFD的依赖关系,针对CRE和容器化VNFC进行差异化部署,增强了容器化VNF部署的弹性(灵活性)。同时提高了容器化VNF部署的效率。
可选地,在该实施例中,如图7所示,在NFVO或EM向VNFM发送第一VNF实例化请求消息之前,该方法还可以包括:
VNFM实例化目标CRE。
在图7中,执行S301至S310之前,已经完成了目标CRE的实例化,且在容器化VNF的VNFD中设置了容器化VNFC与目标CRE的关系信息。
可选地,在一个实施例中,实例化目标CRE的具体过程如图8所示。如图8所示,实例化目标CRE的过程可以包括以下步骤:
S401,NFVO向VNFM发送第二VNF实例化请求消息。
以请求VNFM完成目标CRE的实例化。第二VNF实例化请求消息包括目标CRE实例标识。在该实施例中,可以将目标CRE看作是一种VNF。
S402,NFVO为目标CRE分配第二虚拟机资源的信息。
NFVO向VNFM发送第二VNF实例化请求消息后,为实例化CRE分配虚拟机资源,其具体过程是:NFVO向VIM发送虚拟资源分配请求消息,以用于VIM接收到虚拟资源请求消息后, 为实例化目标CRE分配虚拟机资源,即第二虚拟机资源。第二虚拟机资源的信息包括至少一个分配给目标CRE的虚拟机的标识。
NFVO获取VIM为实例化目标CRE分配的虚拟机资源的信息,并执行S403。

在该实施例中,S402和S403可以在S401之前执行。当VNFM接收到NFVO发送的第二VNF实例化请求消息时,执行目标CRE的实例化。
需要说明的是,在该实施例中,各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本发明实施例的实施过程构成任何限定。
