S402: 根据所述容灾方案配置请求, 确定待配置的应用对象的容灾能力 和容灾约束需求信息;
这里, 待配置的应用对象是指需要配置容灾方案的应用对象, 该应用对 象可以是已部署的应用对象(即已部署在云计算架构中, 但是还未配置容灾 方案的应用对象或者需要对已配置的容灾方案进行^ ί'爹改的应用对象), 也可以 是还未部署的应用对象。
在该步骤中, 若步骤 S401中接收的容灾方案配置请求中只包括待配置的 应用对象的标识信息(可以是名称等信息), 则还需要根据该标识信息, 从已 存储的应用对象信息中查找与该标识信息匹配的应用对象的容灾能力和容灾 约束需求信息; 若步骤 S401中接收的容灾方案配置请求中包括待配置的应用 对象的容灾能力和容灾约束需求信息, 则可以直接从该容灾方案配置请求中 解析出该用对象的容灾能力和容灾约束需求信息。
S403: 根据建立的容灾能力信息库中的基础设施信息、 基础设施管理信 息和应用对象信息以及所述待配置的应用对象的容灾能力和容灾约束需求信 息, 为所述待配置的应用对象确定容灾方案。
该步骤中, 所述基础设施信息可以包括至少一个基础设施的容灾能力信 息和 /或资源使用信息; 这里的资源使用信息包括基础设施和 /或基础设施之间 的剩余可用的容灾资源, 如存储资源、 CPU资源、 网络资源等。 所述基础设 施管理信息包括至少一个基础设施管理的容灾能力信息; 这里, 基础设施管 理可以管理多个 DC下的基础设施, 单个 DC也可以包含多个基础设施管理。 所述应用对象信息包括已部署的至少一个应用对象(可以是一个应用对象、 或由多个应用对象所支持的网络服务 NS, 或包括多个应用对象的 DC ) 的容 灾能力信息、 和 /或容灾约束信息、 和 /或健康状态信息(即容灾能力信息、 容 灾约束信息和健康状态信息中的一种或多种), 这里的健康状态信息是指已部 署的应用对象是否故障、 当前负载状态等信息。
本发明实施例中, 建立了用于收集各基础设施的信息、 各基础设施管理 的信息及已部署的各应用对象的信息的容灾能力信息库, 在接收到容灾方案 配置请求后, 从建立的容灾能力信息库中, 查找支持待配置的应用对象的容 灾能力和容灾约束需求的基础设施、 基础设施管理及已部署的应用对象(可 以用于负荷分担模式下的容灾), 并确定最终的容灾方案。 比如, 可以首先根 据待配置的应用对象的容灾能力和容灾约束需求信息, 确定需要釆用的容灾 模式和容灾机制, 从支持确定的容灾模式和容灾机制的基础设施、 基础设施 管理、数据中心 DC和应用对象中,基于当前空闲资源最富裕、 亲和性和反亲 和性等原则, 挑选出最佳的基础设施、 基础设施管理和数据中心 DC, 基于反 亲和性和应用负载最小等原则, 挑选出最佳的用于负荷分担容灾模式下的应 用对象。 最终确定的容灾方案可以包括以下元素的信息中的一种或多种: 容 灾模式、 容灾机制、 数据中心 DC, 基础设施和基础设施管理、 已部署的应用 对象等。
上述流程中已说明, 本发明实施例的云计算架构可以是基于 ICT的 NFV 架构。 下面针对该云计算架构下的实施作重点说明。
NFV 标准架构中定义了协调整个云系统资源的管理与编排模块 ( Management and Orchestration, MANO ); 如图 5所示, 为 NFV架构中的 MANO接口架构示意图。 NF V架构中定义了网络功能虚拟化基础设施( NF V Infrastructure, NFVI )、虚拟化基础设施管理 ( Virtualised Infrastructure Manager, VIM )、 虚拟化网络功能( Virtualised Network Function, VNF )、 虚拟化网络功 能管理( VNF Manager, VNFM )、网络功能虚拟化管理平台( Network Functions Virtualisation Orchestrator, NFVO )、网元管理系统( Element Management System, EMS )、运营支撑系统 /业务支撑系统( Operation support system/Business support system, OSS/BSS )等功能对象。 其中, NFVI用于提供云化的基础设施, VNF 为云化后的网元应用 , VIM负责基础设施的管理, VNFM负责 VNF的生命周 期管理, NFVO负责业务的生命周期管理, EMS为网元应用的网管, OSS/BSS 为云化系统的网管。
NFV架构是全开放的云化标准架构, 各个部件或同一部件都可以由不同 设备商提供, 可以基于不同层级(基础设施层、 应用层、 管理层)实现容灾, 不同的基础设施、 不同 VNF提供的容灾能力可以不同, 因此, 在 NFV架构 下实现容灾部署, 可以使容灾方案的选择更加灵活。
上述流程中已说明, 本发明实施例的执行主体可以作为容灾方案优选模 块部署在已有的云计算架构的功能实体中, 具体地, 可以部署在 NFV架构下 的 NFVO或 VNFM或 OSS/BSS或 EMS中。 容灾方案优选模块的部署位置决定了基础设施信息、 基础设施管理信息 和应用对象信息等的传递路径, 下面针对将所述容灾方案优选模块部署在
NFVO或 VNFM中进行说明。
下述实施过程中, NFVO中的容灾方案优选模块可以主动向 VIM、 VNFM、 等查询上述基础设施信息、 基础设施管理信息和应用对象信息, 也可以接收 VIM, VNFM等主动发送的基础设施信息、 基础设施管理信息和应用对象信 息, 这里并不限定。 同理, VNFM中的容灾方案优选模块可以主动向 VIM、 VNF等查询上述基础设施信息、 基础设施管理信息和应用对象信息, 也可以 接收 VIM、 VNF等主动发送的基础设施信息、 基础设施管理信息和应用对象 信息, 这里并不限定。
如图 6所示, 为将容灾方案优选模块部署在 NFVO中的示意图, 当将容 灾方案优选模块部署在 NFVO中时, NFVI通过 VIM将基础设施信息传输给 NFVO, 如图 6中标号 1所标示的路径; 也即, VIM将管理的各 NFVI的相关 信息上报给 NFVO, 或者, NFVO可以向 VIM订阅 NFVI的相关信息; VIM 将基础设施管理信息传输给 NFVO, 如图 6中标号 2所标示的路径; VNF通 过 VNFM将应用对象信息 (包括应用对象的容灾能力、 容灾约束、 健康状态 等信息)传输给 NFVO, 如图 6中标号 3a所标示的路径, 或者, VNFM可以 将存储的应用对象信息直接传送给 NFVO, 如图 6中标号 3b所标示的路径; OSS/BSS将容灾方案配置请求(包括用户的容灾约束信息 )传输给 NFVO, 如图 6中标号 4a所标示的路径, 或者, EMS通过 VNFM将容灾方案配置请 求传输给 NFVO, 如图 6中标号 4b所标示的路径, 或者, VNFM将容灾方案 配置请求传输给 NFVO, 如图 6中标号 4c所标示的路径, 或者, NFVO也可 以直接接收用户通过 NFVO的管理软件触发的容灾方案配置请求; 具体地, 传输容灾方案配置请求的方式可以是在虚拟化网络功能描述文件 ( Virtual Network Function Descriptor, VNFD )或网络服务描述文件( Network Service Descriptor, NSD ) 中添加容灾方案配置请求信息, 除此之前, 还可以釆用基 于接口命令的方式传输上述容灾方案配置请求。 具体地,可以在 VNFD或 NSD中定义与配置容灾方案相关的信息或元素, 其中该信息或元素用于标识需要针对设定应用对象或 NS或 DC进行容灾方案 配置, 关于该条信息或元素的描述内容用于表述设定 VNF或 NS或 DC的容 灾配置信息 (包括容灾能力信息和 /或容灾约束信息等)。
比如, 如下表一和表二所示, 可以在 VNFD 中定义一个容灾配置标识 ( Disaster Recovery Configuration Indicator, DRCI ),该 DRCI的描述内容用于 表示对应 VNF的容灾配置信息, 该容灾配置信息包括容灾能力信息、 容灾约 束信息等, 该 DRCI的基数用于表示容灾配置信息的份数, 如表一所示, 该基 数为 0~N, 表示可以不携带容灾配置信息, 也可以携带多份容灾配置信息; 如表二所示, 该基数为 1 , 表示携带一份容灾配置信息。

Figure imgf000018_0001
如图 7所示, 为将容灾方案优选模块部署在 VNFM中的示意图, 当将容 灾方案优选模块部署在 VNFM中时, NFVI通过 VIM将基础设施信息传输给 VNFM, 如图 7中标号 5所标示的路径, 也即, VIM将管理的各 NFVI的相 关信息上报给 VNFM,或者, VNFM可以向 VIM订阅 NFVI的相关信息; VIM 将基础设施管理信息传输给 VNFM, 如图 7中标号 6所标示的路径; VNF将 应用对象信息传输给 VNFM, 如图 7中标号 7所标示的路径; EMS将容灾方 案配置请求传输给 VNFM, 如图 7中标号 8a所标示的路径, 或者, OSS/BSS 将接收的容灾方案配置请求传输给 NFVO, 由 NFVO将该容灾方案配置请求 转发给 VNFM, 如图 7中标号 8b所标示的路径, 或者, NFVO将接收的容灾 方案配置请求传输给 VNFM, 如图 7中标号 8c所标示的路径; 或者, VNFM 也可以直接接收用户通过 VNFM的管理软件触发的容灾方案配置请求。 具体 地,传输容灾方案配置请求的方式可以是在虚拟化网络功能描述文件(Virtual Network Function Descriptor, VNFD )或网络服务描述文件( Network Service Descriptor, NSD ) 中添加容灾方案配置请求信息, 还可以釆用基于接口命令 的方式传输上述容灾方案配置请求。
可见,上述两种信息传递路径中,不管将容灾方案优选模块部署在 NFVO 中还是 VNFM中, 基础设施信息和基础设施管理信息都是通过基础设施管理 传递给该容灾方案优选模块。 也即,
根据以下步骤将基础设施信息和基础设施管理信息收集到建立的所述容 灾能力信息库中: 接收任一基础设施管理传输的该基础设施管理和该基础设 施管理所管理的各基础设施的信息; 将接收的该基础设施管理和该基础设施 管理所管理的各基础设施的信息存储到所述容灾能力信息库中。

根据以下步骤将所述应用对象信息收集到建立的所述容灾能力信息库中: 接收每个应用对象传输的应用对象信息; 将接收的所述应用对象信息存储到 所述容灾能力信息库中。
在具体实施过程中, 当所述基础设施信息、 基础设施管理信息和应用对 象信息中的任意一种发生变化时, 可以通过以上路径将更新的信息及时传输 至容灾能力信息库, 并由容灾方案优选模块根据更新的信息, 对受影响的应 用对象重新制定合适的容灾方案。 具体地, 基于本发明以上实施例提供的信 息传递路径, 当基础设施或基础设施管理的容灾能力等信息发生变化, 比如 软件升级、 新增基础设施部件、 部分基础设施故障等, 容灾能力信息库能及 时更新数据并识别出受影响的应用对象, 然后将这些信息反馈到容灾方案优 选模块, 由容灾方案优选模块对受影响的应用对象重新制定合适的容灾方案, 提醒用户或触发系统自动进行容灾方案的调整。 当已部署的应用对象的容灾 能力或容灾约束等信息发生变化时, 比如软件升级、 用户调整等, 容灾能力 信息库同样能及时更新数据并识别出受影响的应用对象, 然后将这些信息反 馈到容灾方案优选模块, 由容灾方案优选模块对受影响的应用对象重新制定 合适的容灾方案, 提醒用户或触发系统自动进行容灾方案的调整。
