其中, 业务链控制器是用于控制业务链的一个控制器, 业务链 控制器的实质是一个软件自定义网络 ( Software Defined Network, SDN ) 控制器, SDN 控制器通过 OpenFlow 协议实现对下层设备的路 由和数据的转发控制, 具体的对下层设备的路由和数据的转发控制 的方法属于现有技术的方案, 此处不再赘述。
需要说明的是, 业务链控制器具体可以是 GI 局域网 ( Local Area Network, LAN;)控制器, 用于控制 GI LAN网络的业务链, GI LAN 指的是无线 GI接口之后, 互联网 ( Internet ) 之前的一段网络, 由 各种不同的业务功能 ( servicefunct ion, SF ) 组成, 一个业务链由 多个 SF组成, 一个业务链对应一个业务套餐, 一个业务套餐可能包 含多个业务链。

302、 第一通信单元根据所述业务链规则, 获取业务路由通过的 业务链的信息。
其中,所述业务链的信息用于指示业务路由通过的 VNF的信息 , 所述 VNF用于所述业务处理。
具体的, 如步骤 301 所述, 因为所述业务链规则中可能直接包 含业务链的信息, 也可能并未包含业务链的信息, 因此在所述第一 通信单元根据所述业务链规则, 获取业务路由通过的业务链的信息 之前, 还可以包括:
确定所述业务链规则中是否包含业务链的信息;
若所述业务链规则中包含业务链的信息, 可以直接获取所述业 务链规则中包含的所述业务链的信息;

在所述第一通信单元为 PNF单元时, 所述第一通信单元仅能直 接发送所述查询请求消息给 0SS/BSS, 以使得通过所述 0SS/BSS 发 送所述查询请求消息第二通信单元, 不能直接发送所述查询请求消 息给 VNFM。
其中, 所述第二通信单元可以为 VIM, 也可以为 NFVI控制器, 本发明实施例对此不作具体限定。 关于所述 NFVI控制器的相关描述 参见实施例二步骤 501部分, 此处暂不作具体阐述。
当然, 还可能存在其它的根据所述业务链规则, 获取业务路由 通过的业务链的信息的方法, 本发明实施例对此不作具体限定。
需要说明的是, 在所述业务链规则中包含业务链的信息时, 也 可能通过第二通信单元查询业务链中包含的 VNF 的第一信息, 以确 认所述业务链中包含的 VNF 状态是否异常, 在所述第二通信单元查 询到所述业务链中包含的某一 VNF 状态发生异常时 (比如资源负载 超过预设门限), 及时反馈异常信息给所述第一通信单元, 以使得所 述第一通信单元向发送所述业务链规则的实体反馈该异常信息, 进 而所述发送所述业务链规则的实体再根据相应的策略做相应处理, 比如重新发送业务链的信息等, 本发明实施例对所述业务链规则中 包含业务链的信息时是否需要通过第二通信单元查询业务链中包含 的 VNF的第一信息的情况不作具体限定。
303、 第一通信单元发送路由与资源配置请求消息, 所述路由与 资源配置请求消息携带所述业务链的信息, 以请求根据所述业务链 的信息, 对所述业务链中包含的 VNF进行路由与资源的配置。
具体的, 如步骤 301 所述, 所述第一通信单元可以为 VNF单元, 也可以为 PNF单元。
在所述第一通信单元为 VNF单元时, 所述第一通信单元可以直 接发送所述路由与资源配置请求消息给 VNFM, 以使得通过所述 VNFM 发送所述路由与资源配置请求消息给第二通信单元; 也可以直接发 送所述路由与资源配置请求消息给 0SS/BSS , 以使得通过所述 0SS/BSS 发送所述路由与资源配置请求消息给第二通信单元, 本发 明实施例对此不作具体限定。

其中, 如上所述, 所述第二通信单元可以为 VIM,也可以为 NFVI 控制器, 本发明实施例对此不作具体限定。
当然, 若路由与资源配置成功, 所述第一通信单元还可能接收 路由与资源配置成功的指示信息, 本发明实施例对此不作具体限定。
综上, 示例性的, 假设本发明实施例的执行主体第一通信单元 为业务链控制器, 这里提供一个 NFV 系统的业务实现方法场景示意 图如图 4所示, 包括: PCRF 、 PGW, 业务链控制器、 NFV 系统、 以 及可支持的网络, 其中, NFV 系统中包含多个 VNF 类型, 如视频优 化、 内容过滤、 浏览器优化等, 每个 VNF类型包括一个或多个 VNF; 可支持的网络状态为第二代 ( 2rd Generation, 2G ) 网络、 或者通 用移动通信系统 ( Universal Mobile Telecommunications System, UMTS ) 网络、 或者长期演进 ( Long Term Evolution, LTE ) 网络。
在图 4 中, 第三代合作伙伴计划( 3rd Genera t ion Partnership Project , 3GPP ) 网元^口 PCRF作为业务链规则的决策实体, PCRF才艮 据用户信息、 业务信息、 网络信息等决定业务链规则之后, 通知业 务链控制器, 以使得所述业务链控制器获取业务链规则, 其中, 业 务链控制器与无线网络节点 (如 PCRF或者 PGW )之间通过 Diameter 协议进行信息交互, 传送业务链规则。
业务链控制器的作用是获取业务链规则,根据所述业务链规则, 获取业务路由通过的业务链的信息。 一种可能的实现方式下, 若业 务链规则中包含业务链的信息, 业务链控制器可以直接获取业务链 规则中包含的业务链的信息; 若业务链规则中未包含业务链的信息, 由业务链控制器通知 NFV MAN0, 查询 NFVI 的网络拓朴、 资源状态 等信息, 进而根据 NFVI 的网络拓朴、 资源状态的信息, 生成业务链 的信息。 在业务链控制器获取业务链的信息之后, 可以通知 VIM或 者 NFVI控制器进行路由与资源的配置。 其中, 业务链控制器作为一 个 VNF, 与 VNFM之间可以通过 RESTful协议进行信息交互。 基于本发明实施例提供的 NFV 系统的业务实现方法, 因为第一 通信单元可以在获取业务链规则后, 根据所述业务链规则获取业务 路由通过的业务链的信息, 然后发送携带所述业务链的信息的路由 与配置请求消息, 请求根据所述业务链的信息, 对所述业务链中包 含的 VNF 进行路由与资源的配置, 实现了获取上层业务链路信息, 并通过上层业务链信息指导 NFVI 的路由与资源的配置的功能, 进而 可以实现 NFV 网络的业务链的建立。 实施例二、
本发明实施例提供一种 NFV 系统的业务实现方法, 具体如图 5 所示, 包括:
501、 第二通信单元接收路由与资源配置请求消息, 所述路由与 资源配置请求消息携带业务路由通过的业务链的信息, 以请求根据 所述业务链的信息对所述业务链中包含的 VNF 进行路由与资源的配 置。
其中, 所述业务链的信息是根据业务链规则获取的, 所述业务 链规则用于指示需要进行的业务处理, 所述业务链的信息用于指示 业务路由通过的 VNF的信息, 所述 VNF用于所述业务处理。
具体的, 本发明的执行主体第二通信单元可以是 VIM, 也可以 是 NFVI控制器, 本发明实施例对此不作具体限定。 其中, 所述 NFVI 控制器同业务链控制器类似, 实质上也是一个 SDN控制器, 业务链 控制器控制的是 VNF层中 VNF的逻辑与路由, 而 NFVI控制器控制的 是 NFVI 的物理资源的连接与路由。 NFVI 控制器可以部署在 VIM或 者 NFVI 中, 也可以独立部署, 本发明实施例对此不作具体限定。
需要说明的是, 若存在 NFVI控制器, 因为所述 NFVI控制器可 以部署在 VIM 中, 也可以独立部署, 因此本发明实施例中, 将存在 NFVI 控制器, 并且所述 NFVI 控制器部署在 VIM 中的情况下的第二 通信单元认为是 VIM; 而在存在 NFVI 控制器, 并且 NFVI 控制器部 署在 NFVI 中或者独立部署情况下的第二通信单元可以认为是 NFVI 控制器; 若不存在 NFVI控制器, 本发明的执行主体第二通信单元为 VIM。
示例性的, ^ ^设不存在 NFVI控制器, 则可以得到如图 6所示的 NFV系统的业务管理示意图, 其中, 右侧为 NFV MAN0架构, 此处不 再赘述。 业务链控制器控制的是 VNF 层中 VNF 的逻辑与路由, VIM 管理的是 NFVI 的物理资源的连接与路由 , 虚拟机 ( Virtual Manufacturing, VM ) 用于承载虚拟资源。
示例性的, ^^设存在 NFVI 控制器, 则可以得到如图 7 所示的 NFV系统的业务管理示意图, 其中, 右侧为 NFV MAN0架构, 此处不 再赘述。 业务链控制器控制的是 VNF层中 VNF 的逻辑与路由, NFVI 控制器控制的是 NFVI 的物理资源的连接与路由, VM 用于承载虚拟 资源。
具体的, 本发明实施例中, 所述第二通信单元接收的路由与资 源配置请求消息可能是 VNFM发送的, 也可能是 0SS/BSS发送的, 本 发明实施例对此不作具体限定。
502、 第二通信单元根据所述业务链的信息, 以及 NFVI 的物理 资源的信息, 对所述业务链中包含的 VNF进行路由与资源的配置。
具体的, 本发明实施例中, 第二通信单元在接收路由与资源配 置请求消息后, 将根据携带的业务链的信息, 结合 NFVI 的物理资源 的信息, 对所述业务链中包含的 VNF 进行路由与资源的配置, 方法 可以 ^下:
第二通信单元获取到业务链的信息后,结合 NFVI 的物理资源的 信息, 分别确定业务链中包含的 VNF对应的 NFVI 的路由设备, 然后 分别向其对应的 NFVI 的路由设备发送业务路由信息表,由所述 NFVI 的路由设备根据该业务路由信息表来转发相应的业务流。
示例性的, 4艮设业务链的信息为: VNF7- >VNF2- >VNF3, 则可以 在 VNF7 对应的路由设备上发送如情况一或者情况二所示的业务路 由信息表。
情况一: 业务链标识: VNF7->VNF2->VNF3;
VNF7接口: 接口 1;
VNF2接口: 接口 2。
情况二:
业务链标识: VNF7->VNF2;
VNF7接口: 接口 1;
VNF2接口: 接口 2。
其中, 情况一中的业务链标识中包含整条业务链信息, 情况二 中的业务链标识中仅保存下一跳信息。
后续 VNF7 路由设备会根据下发的业务路由信息来转发相应的 业务流, 比如根据上述两种情况提供的业务路由信息表, 业务流会 从 VNF7路由设备的输出接口 1 输出, 从 VNF2路由设备的输入接口 2输入。
需要说明的是,第一通信单元管理的 VNF与 NFVI 的路由设备存 在如图 8所示的对应关系, 即第一通信单元管理的 VNF在 NF V I 的硬 件资源中都存在与其对应的路由设备。
需要说明的是, 本发明实施例中所述资源与配置请求消息中携 带的业务链的信息可能是第一通信单元获取的业务链规则中直接包 含的, 也可能是根据第一通信单元获取的业务链规则, 查询第二通 信单元管理的物理资源信息后获取的,因此本发明实施例提供的 NFV 系统的业务实现方法还可能包括:
接收查询请求消息, 所述查询请求消息携带业务路由通过的 VNF 的类型中每个 VNF 类型包含的 VNF 的标识信息, 请求根据所述 VNF的标识信息,查询所述每个 VNF类型包含的 VNF的第一信息, 所 述第一信息用于指示 NFVI 的网络拓朴、 节点能力以及状态;
根据所述查询请求消息, 查询 NFVI 的物理资源, 并获取所述每 个 VNF类型包含的 VNF的第一信息;
发送所述每个 VNF类型包含的 VNF的第一信息, 以使得根据所 述每个 VNF类型包含的 VNF的第一信息, 生成所述业务链。 其中,所述第二通信单元接收的查询请求消息可能是 VNFM发送 的, 也可能是 0SS/BSS发送的, 本发明实施例对此不作具体限定。
当然, 若路由与资源配置成功, 所述第二通信单元还可能发送 路由与资源配置成功的指示信息, 本发明实施例对此不作具体限定。
基于本发明实施例提供的 NFV 系统的业务实现方法, 因为第二 通信单元可以接收路由与资源配置请求消息, 所述路由与资源配置 请求消息携带业务路由通过的业务链的信息, 以请求根据所述业务 链的信息, 对所述业务链中包含的 VNF 进行路由与资源的配置; 然 后根据所述业务链的信息, 以及 NFVI 的物理资源的信息, 对所述业 务链中包含的 VNF 进行业务的路由与资源的配置, 实现了获取上层 业务链路信息, 并通过上层业务链路信息指导 NFVI 的路由与资源的 配置的功能, 进而可以实现 NFV网络的业务链的建立。 实施例三、
