为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
网络设备：网络设备的种类繁多，包括：交换机、路由器、基站(如基带处理单元BBU、射频拉远单元RRU)等。
协议适配器(Protocal Adapter，PA)：南向接口负责与网络设备通信和交互的插件，可以实现3GPP接口协议功能，例如可以实现CORBA协议、SOAP协议和RESTFul协议等的处理；相应的，协议适配器可以包括CORBA adaptor、SOAP adaptor和RESTFul adaptor等。
南向(Southbound)：管理网管或设备的接口，即向下提供的接口。
南向接入层(South Adapter Layer，SAL)：也叫南向适配层，是基础设施服务，为网管上层应用提供被管理网络设备的南向访问服务。
分布式协同服务(Distributed Cooperative Service，DCS)：用于动态管理各种协议适配器，以及适配器管理的南向对象。
应用(Application，App)：面向用户的上层应用。
随着通信技术的演进，多个制式的网络共存，各种不同协议类型的网络设备都会接入到网络设备管理系统中进行管理，其管理具有以下三个特点：一是网络设备协议类型多。这就需要解决不同通信协议下的网络设备管理问题，消除不同协议之间的差异，统一对网络设备进行管理，在接入新的协议网络设备而不对原有的管理系统架构进行调整，达到动态管理网络设备的目的；二是接入管理的网络设备数量多。对于大量的网络设备接入，能够进行多节点分布式管理，支持弹性扩展，保证系统的可靠性、可用性和存取效率，同时实现故障转移；三是网络设备管理系统和网络设备之间有大量的下行和上行消息进行交互。网络设备管理系统应用层在不暴露网络设备协议的情况下，即无需关注网络设备协议，而是通过路由模块负责协议编码、寻址、存储更新路由表等，实现和不同协议网络设备上下行消息的交互，同时能够应对消息风暴。
基于此，本申请提供了一种网络设备管理方法、装置、系统及存储介质，能够在分布式场景下，将接入的不同协议类型的网络设备分配至对应的协议适配器进行管理，并更新路由表，使不同协议类型的网络设备能够正确寻址，使上层应用能够和不同协议类型的网络设备进行交互的同时，却与网络设备隔离；消除了不同协议类型的网络设备之间存在的差异，能够实现动态新增网络设备类型却不影响原有的架构，达到自适应、高效率管理网络设备的目 的。
下面结合附图1，对相关技术作进一步阐述。
图1是本申请一实施例提供的网络设备管理方法的流程图，本实施例中的网络设备管理方法至少包括以下步骤：
步骤S110：获取网络设备信息与协议适配器信息。
在一些实施例中，网络设备管理方法由分布式协同服务DCS提供。
在一些实施例中，分布式协同服务DCS通过消息中间件动态监听资源数据库获取网络设备信息的创建与删除。
在一些实施例中，分布式协同服务DCS通过接口主动获取网络设备信息的创建与删除。
在一些实施例中，分布式协同服务DCS能够监听到协议适配器实例的创建与删除。
通过对网络设备信息与协议适配器信息的实时获取，动态地将网络设备分配给协议适配器进行管理，实现了对网络设备相对于协议适配器更加准确及时的分配，也能够准确及时地更新路由表，保证通信链路的畅通。
步骤S120：根据预设算法，建立网络设备与协议适配器之间的映射关系。
在一些实施例中，符合要求的协议适配器实例是挂载在分布式协同服务架构的分布式节点下，因此，网络设备与协议适配器PA之间映射关系本质上体现了网络设备与分布式服务架构的分布式节点之间的映射关系。
在一些实施例中，协议适配器PA在注册时自带算法包，算法包中包含有网络设备分配的预设算法，分布式协同服务DCS可根据算法包中的算法进行网络设备的分配。
在一些实施例中，协议适配器PA在注册时未指定算法，因此，分布式协同服务DCS具有默认的算法，分别为最少优先(The Least Priority)算法和均分算法。本领域技术人员知晓最少优先(The Least Priority)算法和均分算法的具体含义，因此在此不做赘述。
步骤S130：根据映射关系，更新路由表，路由表用于建立应用与网络设备之间的通信。
在一些实施例中，分布式协同服务DCS动态地将网络设备分配给协议适配器进行管理，更新路由表。值得注意的是，如果是首次更新，那么就相当于是创建路由表。路由表能够建立应用与网络设备之间的间接的通信。
本申请实施例能够能够在分布式场景下，将接入的不同协议类型的网络设备分配至对应的协议适配器进行管理，并更新路由表，使不同协议类型的网络设备能够正确寻址，使上层应用能够和不同协议类型的网络设备进行交互的同时，却与网络设备隔离；消除了不同协议类型的网络设备之间存在的差异，能够实现动态新增网络设备类型却不影响原有的架构，达到自适应、高效率管理网络设备的目的。
下面结合附图2，对本申请另一实施例作具体阐述。
图2是本申请另一实施例提供的网络设备管理方法的流程图，至少包括以下步骤：
步骤S111：通过消息中间件动态监听网络设备信息的创建与删除；监听协议适配器实例的创建与删除。
消息中间件是利用高效可靠的消息传递机制进行异步的数据传输，并基于数据通信进行分布式系统的集成，通过提供消息队列模型和消息传递机制，可以在分布式环境下扩展进程间的通信。
步骤S121：存在协议适配器实例且协议适配器具备网络设备管理能力，将协议适配器实 例挂载至分布式协同服务架构的分布式节点下。
在一些实施例中，确定协议类型的协议适配器已经成功注册，并已经创建了对应协议类型的协议适配器实例且实例有效，其具体注册过程详见后文实施例。协议适配器实例需要通过挂载在分布式服务架构的分布式节点下才能实施对网络设备的具体操作及管理。
步骤S122：根据均分算法，将网络设备分配至分布式节点下进行管理。
在一些实施例中，可采用其他算法对网络设备进行分配，例如最少优先(The Least Priority)算法等。
在一些实施例中，分布式协同服务DCS通过南向协议适配管理器提供的接口获取指定算法包，并加载执行，计算分配结果，将网元及其网络设备分配到对应的协议适配器实例节点。
步骤S131：根据网络设备与协议适配器之间的映射关系，更新路由表，路由表用于建立应用与网络设备之间的通信。
在一些实施例中，根据分布式协同服务DCS对网络设备相对于协议适配器实例的分配结果，更新路由表。值得注意的是，如果是首次更新，那么就相当于是创建路由表。路由表能够建立应用与网络设备之间的间接的通信。
本申请实施例能够在分布式场景下，将接入的不同协议类型的网络设备分配至对应的协议适配器进行管理，并更新路由表，使不同协议类型的网络设备能够正确寻址，使上层应用能够和不同协议类型的网络设备进行交互的同时，却与网络设备隔离；消除了不同协议类型的网络设备之间存在的差异，能够实现动态新增网络设备类型却不影响原有的架构，达到自适应、高效率管理网络设备的目的。
图3是本申请另一实施例提供的网络设备管理方法的流程图，至少包括以下步骤：
步骤S112：通过接口获取网络设备信息的创建与删除；监听协议适配器实例的创建与删除。
在一些实施例中，分布式协同服务DCS能够通过接口直接获取网络设备信息。
步骤S123：不存在协议适配器实例，默认将网络设备分配至分布式服务架构的缓存节点下进行管理。
在一些实施例中，可能由于协议适配器没有成功注册导致没有协议适配器实例，此时，为了实现网络设备的管理，需要将网络设备分配至分布式服务架构的缓存节点下进行管理，当符合条件的协议适配器实例出现时，再进行重新的分配与转移，这能够使整个分布式服务架构更加具有弹性，使之更具可靠性、可用性和存取效率。值得注意的是，当网络设备挂载在缓存节点时，不进行通信，只有当新的实例注册后，网络设备从缓存节点被分配至注册的实例下，再进行通信。
步骤S132：根据网络设备与缓存节点之间的映射关系，更新路由表，路由表用于建立应用与网络设备之间的通信。
在一些实施例中，根据分布式协同服务DCS对网络设备相对于分布式服务架构的缓存节点的分配结果，更新路由表。值得注意的是，如果是首次更新，那么就相当于是创建路由表。路由表能够建立应用与网络设备之间的间接的通信。
本申请实施例提供的网络设备管理方法适用于协议适配器实例没有成功创建的具体应用场景，实现了网络设备更加灵活的管理，使整个分布式服务架构更加具有弹性，使之更具可靠性、可用性和存取效率。
图4是本申请另一实施例提供的网络设备管理方法的流程图，至少包括以下步骤：
步骤S112：通过接口获取网络设备信息的创建与删除；监听协议适配器实例的创建与删除。
在一些实施例中，分布式协同服务DCS能够通过接口直接获取网络设备信息。
步骤S124：协议适配器实例下管理的网络设备数量达到阈值，根据预设算法，将网络设备分配至分布式协同服务架构的缓存节点下进行管理。
在一些实施例中，协议适配器PA注册成功后，可以进行协议适配器实例的创建，此时，可以一次创建多个协议适配器实例，并提前设置每个实例最多能够管理的网络设备的数量，即阈值，来提升对网络设备的管理效率。当具体某个协议适配器实例下管理的网络设备数量达到阈值时，则此实例不具有管理能力了，因此，将网络设备分配至分布式协同服务架构的缓存节点下进行管理。
在一些实施例中，当一些实例释放了一些网络设备，使符合条件的协议适配器实例出现时，再进行重新的分配与转移，这能够使整个分布式服务架构更加具有弹性，使之更具可靠性、可用性和存取效率。
步骤S132：根据网络设备与缓存节点之间的映射关系，更新路由表，路由表用于建立应用与网络设备之间的通信。
在一些实施例中，根据分布式协同服务DCS对网络设备相对于分布式服务架构的缓存节点的分配结果，更新路由表。值得注意的是，如果是首次更新，那么就相当于是创建路由表。路由表能够建立应用与网络设备之间的间接的通信。
本申请实施例提供的网络设备管理方法适用于协议适配器实例中网络设备管理数量超出阈值的具体应用场景，一方面提升了网络设备管理的效率，另一方面保证了网络设备管理的可靠性，保证大量异步消息能够快速被响应。
在本申请的一些其他实施例中，由于协议适配器实例断链导致的协议适配器不具有对网络设备的管理能力也可能发生，与上述实施例中的原理相同，此时将将网络设备分配至分布式协同服务架构的缓存节点下进行管理，等待合适的条件，再重新分配。
在本申请的一些其他实施例中，网络设备信息被删除时，则将网络设备从协议适配器所在的分布式节点下删除。
在本申请的一些其他实施例中，网络设备断链时，协议适配器会自主选择是否和网元设备进行建链。
上述映射关系的变更会导致路由表的更新，这样应用App根据实时动态更新的路由表，就能与网络设备建立通信。而因为应用App是通过协议适配器与网络设备建立链接，能够使得不同协议类型的网络设备以统一的方式被接入框架进行管理，因此动态新增网络设备类型而不会影响原有的模块，进而实现了自适应管理网络设备的目的。
本申请实施例还提供了一种协议适配器管理方法，如图5所示，至少包括以下步骤：
步骤S210：接收协议适配器信息，协议适配器信息包括协议类型信息。
在一些实施例中，协议适配管理器负责对协议适配器进行管理，管理的依据是协议适配器提供的协议类型信息。
步骤S220：根据协议类型信息，将协议适配器注册至协议适配管理器。
在一些实施例中，协议适配器将自身携带的算法包以及自身协议类型的相关信息发送给 协议适配管理器完成注册操作。
在一些实施例中，协议适配器自身没有算法包或指定算法，因此，可以依赖分布式协同服务DCS具有的默认算法，即最少优先(The Least Priority)算法和均分算法。
值得注意的是，本领域技术人员知晓，协议适配器的注册、注销、修改及查询，均为协议适配管理器对外功能，其能够基于分布式协同服务DCS及其他服务的需求，提供对应功能。
在一些实施例中，协议适配管理器还具有对内实现协议适配器实例的建链、网络设备信息的获取、链路状态的监听以及网元状态的监听等功能。
步骤S230：根据网络设备管理方法，对与协议适配器具有所述映射关系的网络设备进行管理。
在一些实施例中，协议适配器类型注册成功后，可以进行协议适配器实例PA的创建，此时，可以一次创建多个协议适配器实例，并提前设置每个实例最多能够管理的网络设备的数量，即阈值，来提升对网络设备的管理效率。
在一些实施例中，通过将协议适配器创建的实例挂载在分布式网络节点下，实现对网络设备的管理。
在一些实施例中，协议适配管理器位于南向接入层，通过与分布式协同服务DCS实施的网络设备管理方法相配合，共同实现网络设备的管理。
本申请实施例提供的协议适配器管理方法应用于协议适配管理器，通过对注册其下的协议适配器的管理，实现了协议适配器实例的建链，网络设备信息的获取，链路状态的监听与网络设备状态的监听，最终实现对各种网络设备之间的差异的屏蔽，使上层应用可以与网络设备通信、交互，并使协议适配器向上通过南向接入框架暴露统一接口。
本申请实施例还提供了一种通信方法，具体为一种通信转发技术。
在一些实施例中，其通过接收应用发送的通信请求，并根据通信请求与路由表确定目标协议适配器地址，所述路由表通过上述实施例中的网络设备管理方法获得。其通信的本质是与网络设备建立通信连接，但是由于协议的差异性，通过协议适配器进行转发，因此需要对目标的协议适配器进行寻址。而这种通信方式能够使上层应用App和网络设备之间实现解耦。
在一些实施例中，根据目标协议适配器地址，转发通信请求，并接收目标协议适配器返回的处理结果，再将处理结果返回至应用App。
在一些实施例中，通信转发技术中采用负载均衡策略进行通信请求的转发，能够极大地提升系统中消息处理效率。
本申请实施例还提供了一种通信方法，具体应用于协议适配器，通过接收根据路由表转发的应用的通信请求，并与协议适配器具有映射关系的网络设备建立通信连接；将通信请求转发至网络设备，并转发所述网络设备的处理结果至所述应用。
本申请实施例提供的通信方法能够由协议适配器和网络设备建立连接进行通信，实现不同协议下的网络设备的通信连接，进而实现上层应用和网络设备的交互。
本申请实施例还提供了一种通信方法，应用于网络设备，通过与网络设备具有映射关系的协议适配器建立通信连接，并接收路由表转发的来源于应用App的通信请求，并最终发送对应于通信请求的处理结果至协议适配器。
本申请实施例提供的通信方法能够由协议适配器和网络设备建立连接进行通信，实现不同协议下的网络设备的通信连接，进而实现上层应用和网络设备的交互。
本申请还提供了一种网络设备管理系统，如图6所示，系统包括以下三个装置：网络设备管理装置、协议适配管理装置与通信装置。
网络设备管理装置具体包括以下模块：
信息获取模块，用于获取网络设备信息与协议适配器信息；映射关系建立模块，用于根据预设算法，建立网络设备与协议适配器之间的映射关系；路由表更新模块，用于根据映射关系，更新路由表，路由表用于建立应用与网络设备之间的通信。
协议适配管理装置具体包括以下模块：
协议适配器信息接收模块，用于接收协议适配器信息，协议适配器信息包括协议类型信息；协议适配器管理模块，用于根据协议类型信息，将协议适配器注册至协议适配管理器；网络设备管理模块，用于上述实施例中的网络设备管理方法，对与协议适配器具有映射关系的网络设备进行管理。
通信装置具体包括以下模块：
接收模块，用于接收应用发送的通信请求与接收目标协议适配器返回的处理结果；协议适配器地址确定模块，用于根据通信请求与路由表确定目标协议适配器地址；转发模块，用于根据目标协议适配器地址转发通信请求与转发处理结果至应用。
在一些实施例中，协议适配器完成对协议适配器算法包及相关信息的注册，其由协议适配管理装置进行统一管理，实现协议适配器实例的建链、网络设备信息的获取、链路状态的监听与网元状态的监听等。协议适配器类型注册成功后，注册协议适配器实例，可以一次注册多个协议适配器实例来管理分配的网络设备，每个协议适配器实例可以设置容量，来限制管理的设备数。协议适配器实例与协议适配服务建链，协议适配器实例建链成功之后才具备管理网元的能力，并执行相关业务。
在一些实施例中，网络设备管理装置，以分布式协同服务DCS通过消息中间件动态监听或通过接口主动获取网络设备数据创建消息。分布式协同服务DCS监听协议适配器实例的创建，并将协议适配器实例挂载到分布式节点下。具体地，分布式协同服务DCS通过南向适配管理提供的接口获取指定算法包，并加载执行，计算分配结果，将网元分配到对应的协议适配器实例节点。在一些实施例中，如果不存在协议适配器实例，则将网络设备托管到缓存节点下。最后分布式协同服务DCS更新路由表，将网络设备分配结果写入分布式节点下进行维护。监听到协议适配器实例断链或被删除，不具备管理网络设备的能力时，则释放管理的资源，分布式协同服务DCS将当前协议适配器实例下挂载的网络设备按照指定的算法包重新分配到其他协议适配器实例节点下，如果不存在其他的协议适配器实例，或者所有协议适配器实例下挂载的设备数量已经达到上限，则将网络设备挂载到缓存节点下，下次有新的协议适配器实例被创建后，重新进行分配。在监听到网络设备数据被删除后，分布式协同服务DCS会同时将该网络设备从所在的协议适配器实例节点下移除，不再管理该设备。协议适配器实例开始执行业务，和网络设备进行通信。
通讯转发服务进行应用App和协议适配器之间的消息交互，通信装置的具体结构如图7所示。
通信装置中的负载均衡模块用于提供消息转发的负载均衡策略，对外提供接口供各App进行调用，路由表用于存储并实时更新通信地址并实现消息的转发；消息队列模块具体分为请求队列模块与响应队列模块，请求队列模块用于将消息转发至协议适配器，响应队列模块 用于接收协议适配器发送的消息响应。
在一些实施例中，对外提供接口(如Restful接口)供各App进行调用，内部采用负载均衡策略提高系统的高可应用性，通过路由表进行存储，消息队列能够实现单设备消息串行，多设备消息并行，保证大量异步消息能够快速响应。
图8示出了基于Zookeeper的分布式服务架构示意图，Zookeeper分布式协同服务提供了对网络设备的具体管理并实时更新路由表，通信装置通过获取实时更新的路由表，来实现对来自应用App通信请求的精确转发，协议适配器再与其管理的网络设备通信后，将响应的消息返回至通信装置，再由通信装置返回给应用App，进而完成了整个通信过程。
本申请实施例能够在分布式场景下，将接入的不同协议类型的网络设备分配至对应的协议适配器进行管理，并更新路由表，使不同协议类型的网络设备能够正确寻址，使上层应用能够和不同协议类型的网络设备进行交互的同时，却与网络设备隔离，保证大量异步消息能够快速响应；同时消除了不同协议类型的网络设备之间存在的差异，能够实现动态新增网络设备类型却不影响原有的架构，达到自适应、高效率管理网络设备的目的。
本申请的一个实施例还提供了一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行上述实施例的网络设备管理方法、协议适配器管理方法与通信方法。
存储器作为一种非暂态计算机可读存储介质，可用于存储非暂态软件程序以及非暂态性计算机可执行程序。此外，存储器可以包括高速随机存取存储器，还可以包括非暂态存储器，例如至少一个磁盘存储器件、闪存器件、或其他非暂态固态存储器件。在一些实施方式中，存储器可选包括相对于处理器远程设置的存储器，这些远程存储器可以通过网络连接至该处理器。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
