Description

资源预留的方法及VNFM、VIM、NFVO 技术领域
本发明涉及信息技术领域，特别涉及一种资源预留的方法及VNFM、VIM、NFVO。
背景技术
网络功能虚拟化(英文全称：Network Functions Virtualisation，英文缩写：NFV)管理和编排(英文全称：Management and Orchestration，英文缩写：MANO)架构中引入虚拟资源的预留功能，虚拟资源的预留功能为电信级的网络业务(英文全称：Network Service，英文缩写：NS)生命周期管理(英文全称：LifeCycle Management，英文缩写：LCM)提供保障并且以保证在多租户资源竞争的环境下，组成NS的各个虚拟网络功能(英文全称：Virtualised Network Function，英文缩写：VNF)所需的虚拟资源的可用性。
目前，一种资源预留的方法，首先虚拟网络功能管理器(英文全称：Virtualised Network Function Manager，英文缩写：VNFM)向网络功能虚拟化编排器(英文全称：Network Functions Virtualisation Orchestrator，英文缩写：NFVO)发送请求消息，以请求NFVO许可(Grant)VNFM执行VNF LCM操作。然后NFVO向虚拟化基础设施管理器(英文全称：Virtualised Infrastructure Manager，英文缩写：VIM)发送请求消息，以使得VIM针对该VNF LCM操作所需的虚拟化资源(计算、存储和网络)进行资源预留。若资源预留成功后，NFVO将携带有资源预留标识符的许可确认消息发送至上述VNFM，最后VNFM根据该资源预留标识符和VIM进行交互，执行实际的资源分配过程。
申请人发现，现有技术的资源预留和分配方法信令交互复杂，资源预留的执行效率低。

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它实施例，都属于本发明保护的范围。
本发明实施例提供了一种资源预留的方法，应用于NFV MANO系统，如图1所示，该资源预留的系统包括：NFVO、VNFM、VIM、运营支撑系统(英文全称：Operation support system，英文缩写：OSS)/业务支撑系统(英文全称：Business support system，英文缩写：BSS)、EMS、VNF以及虚拟化功能基础设施(英文全称：Network Functions Virtualisation Infrastructure，英文缩写：NFVI)，其中，NFVO与VNFM进行信息交互，VNFM与VIM通过Vi-Vnfm接口进行信息交互，OSS/BSS与NFVO通过Os-Nfvo接口进行信息交互，NFVO与VNFM通过Nfvo-Vnfm接口进行信息交互，NFVO与VIM通过Nfvo-Vi接口进行信息交互；EMS与VNFM通过VeEn-Vnfm接口进行信息交互，VNF与VNFM通过VeNf-Vnfm接口进行信息交互，其中各个结构的功能如下：
NFVO用于实现网络服务生命周期的管理，并VNFM配合实现VNF的生命周期管理和资源的全局视图功能；
VNFM用于实现虚拟化网元VNF的生命周期管理；
VIM用于主要负责基础设施层硬件资源，虚拟化资源的管理，监控和故障上报，面向上层应用提供虚拟化资源池；
EMS用于针对VNF执行传统的错误、配置、计帐、性能和安全(英文全称：Fault Configuration Accounting Performance and Security，英文缩写：FCAPS)功能；
VNF可以由多个更低级别的组件来组成，其中，一个VNF可以部署在多个虚拟机(英文全称：Virtualized Machine，英文缩写：VM)上，每个VM host一个VNF组件，VNF也可以部署在一个VM上；
虚拟化功能(英文全称：Network Functions Virtualisation，英文缩写： NFV)实例(英文全称：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。其中，VNFR记录VNF运行信息的文件，NFVI资源(英文全称：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；

本发明实施例提供一种资源预留的方法，能够提高资源预留的执行效率，如图2所示，所述方法包括：
201、虚拟网络功能管理器VNFM向网络功能虚拟化编排器NFVO发送请求消息。
其中，请求消息携带有指示VNFM是否支持资源预留的能力标志信息，请求消息用于VNFM向NFVO请求授权执行资源预留的过程。
对于本发明实施例，当VNFM接收到NFVO发送的VNF LCM操作请求时或者VNFM接收到EM发送的VNF LCM操作请求时，VNFM向NFVO发送请求消息。
对于本发明实施例，上述能力标志信息用于表征该VNFM在Vi-Vnfm接口是否存在执行资源预留操作的能力。
202、VNFM接收到NFVO返回的响应消息。
其中，响应消息中携带有资源预留的指示信息，资源预留的指示信息用于指示NFVO是否授权VNFM执行资源预留的过程。
对于本发明实施例，当NFVO确定授权该VNFM执行资源预留的过程时，VNFM将接收到NFVO发送的携带有资源预留授权指示信息的响应消 息，从而获知NFVO是否授权其进行资源预留的过程。
对于本发明实施例，若响应消息中携带的指示消息表征NFVO授权VNFM执行资源预留的过程，则上述响应消息中还携带有资源预留的上限信息，该上限信息用于限定该VNFM进行资源预留的累计资源的上限。
203、若NFVO授权VNFM执行资源预留的过程，则VNFM向虚拟化基础设施管理器VIM发送资源预留请求消息。
其中，资源预留请求消息用于VNFM请求VIM为其预留资源。
对于本发明实施例，当VNFM接收到NFVO发送的响应消息中携带授权VNFM执行资源预留过程的指示消息，则VNFM向VIM发送资源预留请求消息，以使得VNFM获知VIM为其预留的资源。
本发明实施例提供的资源预留的方法中，VNFM向NFVO发送请求消息，请求消息携带有指示VNFM是否支持资源预留的能力标志信息，请求消息用于VNFM向NFVO请求授权执行资源预留的过程，以使得获取资源预留许可。通过直接与VIM进行交互以执行资源预留的过程，而不需要每次进行资源预留时，均需要向NFVO发起许可请求，减少了额外的信息交互的过程，从而可以提高资源预留的执行效率。
本发明实施例的另一种可能的方式中，在图2所示的基础上，步骤203、若NFVO授权VNFM执行资源预留的过程，则VNFM向虚拟化基础设施管理器VIM发送资源预留请求消息，之前还包括如图3所示的步骤301。
301、VNFM接收NFVO发送的第一配置策略信息。
其中，第一配置策略信息携带有一个或多个VNF分别对应的亲和性规则，其中，亲和性规则包括：每个VNF实例的标识与每个VNF实例归属的亲和性组的标识之间的对应关系。
对于本发明实施例，第一配置策略信息为确保VNFM发起资源预留的所需的运营商策略信息。在本发明实施例中，第一配置策略信息可以通过Or-Vnfm接口上特定的配置命令实现，或者将第一策略信息封装至VNF描述文件中，并将该VNF描述文件下发至VNFM。在本发明实施例中，第一配置策略信息主要用于将不同的VNFM管理的VNF实例之间的亲和性规则或者反亲和性规则的策略信息下发给不同的VNFM。不同的VNFM管理 的VNF实例之间的亲和性规则或者反亲和性规则也可以理解为跨VNFM管理域的不同VNF组成的亲和性规则或者反亲和性规则。
对于本发明实施例，VNFM接收到NFVO发送的第一配置策略消息，从而VNFM获知其管理的VNF实例所对应的亲和性组标识和/或反亲和性组标识。在本发明实施例中，每个VNFM管理一个或者多个VNF实例，每个VNF实例归属于一个或者多个亲和性组和/或反亲和性组。
对于本发明实施例，第一配置策略信息为该VNFM管理的一个或者多个VNF实例分别对应的亲和性规则和/或反亲和性规则。在本发明实施例中，该亲和性规则包含了VNF实例的标识与VNF实例归属的亲和性组标识之间的对应关系，反亲和性规则包含了VNF实例的标识与反亲和性组标识之间的对应关系。
例如，在一个亲和性规则中，VNFM1管理如下的VNF实例：VNF1以及VNF2，VNFM2管理如下的VNF实例：VNF3，VNF4以及VNF5，则该亲和性规则可以表示为{VNF1，Affinity Group 1}，{VNF2，Affinity Group 1}，{VNF3，Affinity Group 1}，{VNF4，Affinity Group 1}以及{VNF5，Affinity Group 1}。其中，Affinity Group 1用于标识组成该亲和性组的成员VNF的集合，通过这种表示方式可以将成员VNF实例归属于不同VNFM的亲和性规则下发到不同的VNFM。反亲和性规则的表示方式以及配置流程与亲和性规则的表示方式与配置流程相似，在此不再赘述。
本发明实施例的另一种可能的实现方式，在如图3所示的基础上，所述方法还包括如图4所示的步骤401。
401、VNFM将第一配置策略消息发送至网元管理器EM。
对于本发明实施例，当VNFM接收NFVO发送的第一配置策略信息后，可以将该第一配置策略信息发送至网元管理器(英文全称：Element Manager，英文缩写：EM)，EM将保存每个VNF实例与亲和性组标识和/或反亲和性组标识之间的对应关系，从而当EM由于操作、维护和管理(英文全称：Operations Administration and Maintenance，英文缩写：OAM)的需要而发起新的VNF实例创建过程时，EM将根据新创建的VNF实例替换旧的VNF实例重新构建亲和性规则和/或反亲和性规则，即：对于之前 的亲和性规则和/或反亲和性规则中VNF实例标识与亲和性组标识和/或反亲和性组标识之间的对应关系，用新创建的VNF实例替换旧的VNF实例，得到新创建的VNF实例标识与亲和性组标识和/或反亲和性组之间的对应关系。
对于本发明实施例，综上所述，VNFM通过将第一配置策略信息发送至EM，以使得EM能够保存每个VNF实例标识与亲和性组标识和/或反亲和性组标识之间的对应关系，当终结一个过时的VNF实例并创建一个新的VNF实例时，能够确定该新创建的VNF实例对应的亲和性组标识和/或反亲和性组标识并传递给VNFM，从而可以使VNFM获取新创建的VNF实例的亲和性规则和/或反亲和性规则。
本发明实施例的另一种可能的实现方式，在如图4所示的基础上，所述方法还包括如图5所示的步骤501。
501、当EM创建新的VNF实例后，VNFM接收EM发送的第二配置策略信息。
其中，第二配置策略信息中携带有更新后的VNF的亲和性规则，其中，更新后的VNF的亲和性规则包括：替换原有的VNF实例的新的VNF实例的标识以及原有的VNF实例归属的亲和性组的标识之间的对应关系，其中，原有的VNF实例为第一配值策略消息中的VNF实例。
对于本发明实施例，当EM创建新的VNF实例后，将新创建的VNF实例标识替代旧的VNF实例标识，得到替代旧的VNF实例的新的VNF标识以及原有的VNF实例归属的亲和性组标识和/或反亲和性组标识之间的对应关系。

601、虚拟化基础设施管理器VIM接收虚拟网络功能管理器VNFM发送的资源预留请求消息。
其中，资源预留请求消息携带有预留资源进行生命周期管理操作的VNF所归属的亲和性组的标识。
对于本发明实施例，上述资源预留请求消息中还携带有预留资源的类型、数量、实施时间以及结束时间。
对于本发明实施例，当VNFM被NFVO授权执行资源预留的过程，VIM接收VNFM发送的资源预留请求消息，并根据该资源预留请求消息，确定是否响应该资源预留请求消息。
对于本发明实施例，预留资源的类型包括计算、存储以及网络虚拟资源。
602、VIM根据亲和性组对应的资源位置的虚拟资源的可用情况，确定是否响应VNFM发送的资源预留请求消息。
对于本发明实施例，每一个亲和性组均有与之相对应的固定资源位置，VIM只能为该亲和性组的成员VNF实例预留或分配该固定资源位置内的资源。在本发明实施例中，上述固定资源位置可以包括：由若干个虚拟机组成的资源池，或者同一主机内的一块地址空间等。在本发明实施例中不做限定。
对于本发明实施例，资源预留请求消息中携带有预留资源进行生命周期管理操作的VNF实例所归属的亲和性组的标识，则VIM根据VNF所归属的亲和性组的标识，确定该亲和性组对应的固定资源位置，并根据资源预留请求消息中携带的预留资源的类型、数量、起始时间、结束时间，确定该固定资源位置处的资源情况，是否能够满足该VNFM对资源的需求。
603、若VIM响应VNFM发送的资源预留请求消息，则VIM向VNFM发送资源预留响应消息。
其中，资源预留响应消息中携带有VIM为VNFM预留资源的标识信息。
对于本发明实施例，若VIM判断VNFM管理的VNF实例所属的亲和性 组所对应的固定资源位置中资源，能够满足该VNFM的资源需求，则VIM向VNFM发送资源预留响应消息。
本发明实施例提供了一种资源预留的方法，VIM接收VNFM发送资源预留请求消息，能够响应该VNFM发送的资源预留请求消息，并为该VNFM预留资源，而不需要VNFM在每次向NFVO发送VNF LCM操作许可请求后由NFVO为其进行资源预留，减少了额外信息交互的过程。从而可以提高资源预留的执行效率。
本发明实施例的另一种可能的实现方式，在如图6所示的基础上，步骤601、虚拟化基础设施管理器VIM接收虚拟网络功能管理器VNFM发送的资源预留请求消息，之前还包括如图7所示的步骤701-702。
701、VIM接收NFVO发送的资源预留配置策略。
其中，资源预留配置策略中包括进行资源预留的VNF实例归属的亲和性组的标识。
对于本发明实施例，在VIM接收到VNFM发送的资源预留请求消息之前，该VIM还可能接收NFVO发送的资源预留配置策略。

702、VIM根据资源预留配置策略，确定进行资源预留的VNF实例归属的亲和性组的标识与资源位置之间的对应关系。
对于本发明实施例，资源预置配置策略用于为每个亲和性组分配固定资源位置。在本发明实施例中，VIM根据VNF实例归属的亲和性组的标识以及资源预留配置策略，确定资源预留的VNF实例归属的亲和性组的标识与固定资源位置之间的对应关系。
对于本发明实施例，VIM通过接收NFVO资源预留配置策略中进行资源预留的VNF实例归属的亲和性组的标识，能够确定进行资源预留的VNF实例归属的亲和性组的标识与资源位置之间的对应关系，从而可以当VIM接收到VNFM的资源预留请求时，在该VNFM所管理的VNF实例归属的亲和性组，对应的固定资源位置处为其进行资源预留。
本发明实施例的另一种可能的实现方式，在如图7所示的基础上，所 述方法还包括如图8所示的步骤801，其中，资源预留配置策略还包括：优先响应资源预留请求消息的权重信息，优先响应资源预留请求消息的权重信息为VNFM在其所管理的VNF实例所归属的亲和性组中优先被响应资源预留请求的权重信息。
801、当VIM同时接收到同一个亲和性组中的不同VNF实例所属的VNFM发送资源预留请求消息时，VIM根据优先响应资源预留请求消息的权重信息，确定需要优先响应资源预留请求消息的VNFM，并向VNFM发送资源预留响应消息。
对于本发明实施例，VIM接收NFVO发送的资源预留配置策略中还包含优先响应资源预留请求消息的权重信息，因此当同一个亲和性组中的不同的VNF实例所对应的多个VNFM同时向VIM发送资源预留请求消息时，VIM根据优先响应资源预留请求消息的权重信息，优先响应权重信息值较高的VNFM发送的资源预留请求消息。
例如，当VIM在亲和性组1对应的固定资源位置处可用的资源为7G存储器和2.5GHzCPU的虚拟资源时，VNFM1和VNFM2同时向VIM发送资源预留请求消息，以请求预留5G存储器，2GHzCPU的虚拟资源。VNFM1在亲和性组1中的优先响应资源预留请求的权重信息为0.75，VNFM2在亲和性组1中的优先响应资源预留请求消息对应的权重信息为0.25，则VIM根据VNFM1和VNFM2在亲和性组1中的优先被响应资源预留请求的权重信息，在无法同时满足VNFM1以及VNFM2的资源预留请求时，优先响应VNFM1发送的资源预留请求消息。
对于本发明实施例，当同一个亲和性组中不同的VNF实例所对应的多个VNFM向VIM发送资源预留请求时，能够根据每个VNFM在其管理的VNF实例对应的亲和性组中分别对应的权重信息，确定需要优先响应资源预留请求消息的VNFM，从而可以解决当同一个亲和性组中多个VNF实例所对应的多个VNFM同时向VIM发送资源预留请求时，如何确定需要响应资源预留请求的VNFM。
进一步地，本发明实施例提供了另一种资源预留的方法，VIM通过接收NFVO资源预留配置策略中进行资源预留的VNF实例归属的亲和性组 的标识，能够确定进行资源预留的VNF实例归属的亲和性组的标识与资源位置之间的对应关系，从而可以当VIM接收到VNFM的资源预留请求时，在亲和性组对应的固定的资源位置处为其进行资源分配；当同一个亲和性组中不同的VNF实例所对应的多个VNFM向VIM发送资源预留请求时，能够根据每个VNFM在其管理的VNF实例对应的亲和性组中分别对应的权重信息，确定需要优先响应资源预留请求消息的VNFM，从而可以解决当同一个亲和性组中多个VNF实例所对应的多个VNFM同时向VIM发送资源预留请求时，如何确定需要响应资源预留请求的VNFM。
本发明实施例提供了另一种资源预留的方法，如图9所示，所述方法包括：
901、网络功能虚拟化编排器NFVO接收虚拟网络功能管理器VNFM发送的请求消息。
其中，请求消息中携带有指示VNFM是否支持资源预留的能力标志信息，请求消息用于VNFM向NFVO请求授权执行资源预留的过程。
对于本发明实施例，当VNFM需要进行虚拟资源的预留过程时，需要向NFVO发送请求消息，以请求NFVO授权该VNFM执行资源预留的过程。
902、NFVO根据预置策略以及指示VNFM是否支持资源预留的能力标志信息，确定是否授权VNFM执行资源预留的过程。
对于本发明实施例，当NFVO接收到VNFM发送的请求消息时，NFVO首先根据请求消息中携带的能力标志信息，确定是否授权该VNFM执行资源预留的过程，然后NFVO根据内部的VNF部署信息以及操作策略，再次确定是否授权VNFM执行资源预留的过程。

其中，响应消息中携带有资源预留的指示信息，资源预留的指示信息用于指示NFVO是否授权VNFM执行资源预留的过程。
对于本发明实施例，当NFVO确定授权该VNFM执行资源预留过程，则NFVO向该VNFM发送响应消息，并且响应消息中携带有资源预留的指示消息，用于指示是否授权该VNFM执行资源预留的过程。
本发明实施例提供了一种资源预留的方法，NFVO接收到VNFM发送 的请求消息，能够授权VNFM执行资源预留的过程，而不需要每次进行VNF LCM操作的资源预留时，均需要向VNFM发送许可确认消息，以允许VNFM与VIM执行资源分配的过程，从而减少了NFVO与VNFM进行信息交互的流程，从而可以提高资源预留的执行效率。
本发明实施例的另一种可能的实现方式，在如图9所示的基础上，步骤903、NFVO向VNFM发送响应消息，之后还包括如图10所示的步骤1001。

对于本发明实施例，VNFM标识也可以表示为VIM可识别的租户标识(英文全称：Tenant Identity)，用于表征VIM虚拟资源租用者的身份信息。在本发明实施例中，NFVO可以根据亲和性组中该VNFM管理的VNF实例的数量比例，确定该VNFM对应的上述优先响应资源预留请求消息的权重信息。
例如，在前述的例子中，VNFM1管理亲和性组1中6个成员VNF实例，VNFM2管理亲和性组1中2个成员VNF实例，该亲和性组1不包含归属其他VNFM管理的成员VNF实例，则VNFM1在亲和性组1中的优先响应资源预留请求的权重信息确定为0.75，VNFM2在亲和性组1中的优先响应资源预留请求消息对应的权重信息确定为0.25。
对于本发明实施例，NFVO通过向VIM发送每个VNFM标识分别对应的优先响应资源预留请求消息的权重信息，能够当同一个亲和性组中所属的多个VNF实例对应的多个VNFM同时向VIM发送资源预留请求消息，确定优先响应的VNFM。
