Description

一种资源管理方法及装置 技术领域
本发明涉及网络通信技术领域,尤其涉及一种资源管理方法及装置。
背景技术
NFV(Network Function Virtualization,网络功能虚拟化)是电信网络运营商通过借鉴IT领域的虚拟化技术,在通用的高性能服务器、交换机和存储中实现部分电信网络功能的技术。这种技术需要电信网络功能以软件方式实现,并能在通用的服务器、交换机和存储等硬件上运行,同时根据需要自动化地进行实例化、弹性伸缩、迁移等操作。目前,电信网络中的诸多专用网元设备如防火墙、路由器、CG-NAT(Carrier Grade NAT,运营商级网络地址转换)等,都可以通过NFV技术实现虚拟化。
如图1是NFV端到端架构,主要包括如下三个部分:
一、VNF(Virtualized Network Function,虚拟网络功能):
VNF指虚拟化的网络功能,如虚拟化的EPC(Evolved Packet Core,演进的分组核心网)节点(MME(Mobility Management Entity,移动管理实体)、SGW(Serving GateWay,服务网关)、PGW(Packet Data Network GateWay,分组数据网络网关)等),对应于传统网络中的PNF(Physical Network Function,物理网络功能)。NFV希望同类的VNF和PNF能够具备相同的功能、性能及外部接口。VNF可以由多个VNFC(VNF Component,虚拟网络功能组件)组成,一般一个VNFC运行在一个VM(Virtualized Machine,虚拟机)中,因此,在部署上,一个VNF可以包含一个或多个VM。
EMS(Element Management System,网元管理系统):针对VNF执行传统的FCAPS(Fault management,Configuration management,Account management,Performance management,Security management,故障、配置、计费、性能、安全管理)功能。
二、NFVI(NFV Infrastructure,NFV基础设施):
NFVI提供整个系统运行的硬件和虚拟资源,由硬件资源(包括:计算、网络、存储三部分)、虚拟化层(将硬件资源虚拟化成资源池)和虚拟资源(同样包括:计算、网络、存储三部分)。
三、MANO(Management and Orchestration,管理和编排):
MANO主要由三种实体构成:
VIM(Virtualized Infrastructure Manager,虚拟化基础设施管理器):NFVI的管理单元,在功能上包括硬件资源管理和虚拟资源管理。
NFVO(NFV Orchestrator,NFV编排器):负责对NS(Network Service,网络服务,由多个VNF组成的服务单元,如EPC)进行生命周期管理,并对整个NFV系统的资源(包括硬件资源和软件资源)进行编排和管理。
VNFM(VNF Manager,VNF管理器):负责对VNF进行生命周期管理。
在图1所示的OSS/BSS(Operation Support System/Business Support System,运营/业务支撑系统)指运营商的OSS/BSS,不包括在NFV系统组件中,属于有关系的外部实体。
目前,NFV的标准化工作聚焦在MANO中,如图2所示,为MANO的详细架构,基本与上节中相同,但出现了四个新增实体:NS Catalog(Network Service Catalog,网络服务目录)、VNF Catalog(目录)、NFV Instances(实例)、NFVI Resources(资源),它们是MANO中存储NS、VNF信息、软件包及运行状态的功能模块,其中:
NS Catalog:存储所有已经上架(on-board)的NSD(NS Descriptor,NS描述符)信息。
VNF Catalog:存储所有已经上架的VNF Packages(软件包,包含VNFD(VNF Descriptor,VNF描述符)、虚拟机镜像等)。
NFV Instances:存储所有正在运行的NS、VNF等实例的状态信息,如分配的网络地址、操作记录等。
NFVI Resources:存储所有NFVI资源的状态,包括可用的/已预留的/已分配的NFVI资源。
在实际的NFV MANO应用中,NFVO的管理域和运营商网络域存在一定 的映射关系。例如:对于中小国家的运营商,一个NFVO的管理域能映射到该运营商的全国网络;而对于中国、美国这样的超级大国的运营商,一个NFVO的管理域可能只能映射到一个省份公司的网络。
发明人经过研究发现,在某些应用场景中,例如,在全球性企业的企业网中采用NFV技术,或者对海啸地震活动带地区的VNF选择非活动带的VNF进行可靠性容灾备份(活动带与非活动带通常跨越不同的国家或者跨越不同省份)时,需要将NS部署在不同的NFVO管理域。如图3所示,两个不同管理域的NFVO(NFVO1和NFVO2)通过水平方向接口(图3中NFVO1和NFVO2之间的粗线)完成跨NFVO域的NS的部署。在图中,VNF1、VNF2、VNF3、VNF4共同组成一个NS,其中VNF1~3部署在NFVO1管理域内,VNF4部署在NFVO2管理域内。
现有技术中的NFV标准中的资源管理只涉及一个NFVO管理域,而对于跨NFVO管理域的资源管理并不适用。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
为描述方便,本发明实施例以一个主编排器和一个从编排器为例,但是,基于本申请的方案,一个主编排器和多个从编排器的应用场景也在本申请方案保护范围内,需要说明的是,主编排器与从编排器分别具有不同的管理域。另外,主编排器和从编排器均可具体为NFVO,当然,主编排器和从编排器具体也可以为其他具有资源的管理与编排功能的实体,如NSO(Network Service Orchestrator,网络服务编排器)、RO(Resource Orchestrator,资源编排器),其中,NSO和RO为将NFVO实体拆分后得到的子编排器,NSO负责网络服务的管理与编排,RO负责虚拟资源的管理和编排,对此,本申请并不进行限定。主编排器为NFVO、NSO、RO中的任意一种均可,从编排器也为NFVO、NSO、RO中的任意一种均可。
以主编排器和从编排器均为NFVO为例,如图3所示,两个不同管理域的NFVO(NFVO1和NFVO2)通过水平方向接口(图3中NFVO1和NFVO2 之间的粗线)完成跨NFVO域的NS的部署。需要说明的是,编排器的主从关系是由跨NFVO域的NS的创建者/主导者决定的。同一个编排器对于它管理的不同的NS来说,可能是主编排器也可能是从编排器。假设图3中的OSS(或,管理者)通过NFVO1进行了NS1的实例化过程,则设置NFVO1为主编排器,NFVO2为从编排器,在图中,VNF1、VNF2、VNF3、VNF4共同组成一个NS1,其中VNF1~3部署在NFVO1的管理域内,VNF4部署在NFVO2的管理域内。

在上述本发明公开的实施例的基础上,下面将通过主编排器与从编排器间的信令交互对本发明公开的资源管理方法进行详细描述。
请参阅附图6,为本发明公开的一种资源管理方法实施例1的信令交互示意图,该实施例中,主编排器用P-NFVO表示,从编排器用S-NFVO表示,主编排器的管理域内的VIM用VIM-1表示,从编排器的管理域内的VIM用VIM-2表示,主编排器的管理域内的VNFM用VNFM-1表示,从编排器的管理域内的VNFM用VNFM-2表示,该方法应用于接收NS实例化请求之后,具体包括如下步骤:
A0,P-NFVO接收NS实例化请求。
A1,P-NFVO验证NS实例化请求。
A2,P-NFVO向VNFM-1发送查询VNF是否存在的指令。
A3,VNFM-1向P-NFVO发送查询结果。
A4,P-NFVO向VIM-1发送查询P-NFVO的管理域内的资源的可用性或预留P-NFVO的管理域内的资源的指令。

S-NFVO在接收到P-NFVO发送的S-NFVO的管理域内的资源的可用性或 者预留S-NFVO的管理域内的资源的指令之后,可以对该指令进行验证,这里的验证包括P-NFVO的身份验证和指令内容的正确性验证。
A11,VIM-2查询S-NFVO的管理域内的资源的可用性或者预留S-NFVO的管理域内的资源。
A12,VIM-2向S-NFVO返回查询结果或预留资源信息。

P-NFVO根据查询结果或预留资源信息继续执行NS实例化的过程,具体的,可以分别向VIM-1发送本地实例化的请求,向S-NFVO发送跨域实例化的请求,该部分内容不在本申请范围内,故其具体实现不在本实施例中进行限定。
需要说明的是,P-NFVO可以对S-NFVO返回的预留资源信息进行修改,以标明其所描述的资源属于另一个NFVO管理域。当根据此预留资源信息进行资源分配时,P-NFVO需要将其转换回原来的值,以便S-NFVO域识别。

B0,P-NFVO向S-NFVO发送申请资源配额请求。
B1,S-NFVO向VIM-2发送申请资源配额请求。

VIM-2根据策略或事前协定分配相应的配额。
B3,VIM-2向S-NFVO发送配额分配大小。
B4,S-NFVO向P-NFVO发送配额分配大小。
可选的,P-NFVO将配额分配大小存储到VIM-1上,以使VIM-1获取全局的可用资源信息。
需要说明的是,后续NS实例化过程中对资源的使用可以通过查询P-NFVO或VIM-1的信息来直接得到可用资源的信息,而无需向S-NFVO发起相关请求。
进一步需要说明的是,当配额需求变化时(如配额不足需要增加),P-NFVO可向S-NFVO发起调整资源配额请求对配额大小进行变更。请参阅附图8,为本发明公开的一种资源管理方法实施例3的信令交互示意图,该实施例中,主编排器用P-NFVO表示,从编排器用S-NFVO表示,主编排器的管理域内的VIM用VIM-1表示,从编排器的管理域内的VIM用VIM-2表示,主编排器的管理域内的VNFM用VNFM-1表示,从编排器的管理域内的VNFM用VNFM-2表示,该方法应用于接收NS实例化请求之前,如P-NFVO与S-NFVO建立连接时,或上一次资源查询/预留过程中,具体包括如下步骤:
C0,P-NFVO向S-NFVO发送调整资源配额请求。
C1,S-NFVO向VIM-2发送调整资源配额请求。
