Description

报文的生成方法及相关设备
本申请要求于2018年3月23日提交中国国家知识产权局、申请号201810245562.0、申请名称为“报文的生成方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种报文的生成方法及相关设备。
背景技术
网络管理系统(net manager system，NMS)或软件定义网络(software defined networking，SDN)中的控制器，属于网络的控制层。控制层中的控制器通常通过北向接口(northbound interface，NBI)与位于网络应用层的应用服务器连接，并且通过南向接口(sorthbound interface，SBI)和位于网络基础设施层的网元连接。在为网元进行参数配置时，NMS或SDN控制器获取来自业务服务器的北向请求，对北向请求进行分解和编排，以确定需要进行参数配置的一个或多个网元，然后为这些网元生成相应的南向报文并进行下发，网元根据接收到的南向报文更新其对应的配置数据。当向网元发送的南向报文是根据同一个北向请求生成的南向报文时，若其中任意一个或多个南向报文处理不成功时，可认为该北向请求处理不成功，因此需要保证对南向报文处理成功的网元的配置数据恢复为更新前的状态，以便重新根据北向请求进行南向报文的下发。
为了实现上述目的，传统方式在NMS或SDN控制器中手动编写使网元配置数据恢复到更新之前状态的逆操作报文，不仅开发效率低下，而且容易出错。
发明内容
本申请实施例提供了一种报文的生成方法及相关设备，能够解决现有技术中通过手动编写逆操作报文导致的效率低下且准确性较低的问题。
本申请第一方面提供一种报文的生成方法，该方法用于NMS或SDN控制器，所述方法包括：

通过将原始配置数据和目标配置数据进行比对，判断第二操作指令的操作类型为合并操作、第二操作指令的操作数据为原始配置数据中的第一配置数据时，可以将目标配置数据恢复为原始配置数据，针对性的得到第二操作指令的操作类型和操作数据，从而提高数据恢复的准确性。

具体实施方式
本申请实施例提供了一种报文的生成方法及相关设备，用于在NMS或SDN控制器中生成使网元配置数据恢复到更新之前状态的逆操作报文，提高开发效率，提高准确性。
下面结合附图，对本申请的实施例进行描述。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，这仅仅是描述本申请的实施例中对相同属性的对象在描述时所采用的区分方式。此外，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。
如图1所示，为参数配置的系统的示意图，该系统中包括业务服务器101、NMS或SDN控制器102和网元103。
业务服务器101可以与用户进行交互，即用户可以通过交互界面向业务服务器发送命令，业务服务器在接收到命令后可以生成相应的北向请求。NMS或SDN控制器102中，NMS是网络管理系统，可以用于管理不同地域和不同设备供应商的网络，实现告警、配置、安全和计费等功能，SDN控制器是软件定义网络中的控制器。网元103通常是交换机。
业务服务器101还与NMS或SDN控制器102的北向接口相连，通过该北向接口向NMS或SDN控制器102发送北向请求。网元103与NMS或SDN控制器102的南向接口连接，可以通过南向接口获取南向报文。
NMS或SDN控制器102包括北向请求处理模块1021和南向请求处理模块1022。
北向请求处理模块1021包括北向请求接收模块10211、北向请求分析模块10212和南向请求编排模块10213。其中，北向请求接收模块10211通过北向接口获取来自业务服务器101的北向请求。在本实施例中该北向请求可以是对网元103中存储的配置数据进行更新的请求。此处的更新可以包括新增、修改和/或删除。北向请求分析模块10212用于对北向请求进行分析，例如判断该北向请求的类型、北向请求是否合法等，在判断该北向请求合法后，可以根据北向请求的类型确定该北向请求涉及的网元、对应于各个网元的具体操作等。南向请求编排模块10213根据北向请求分析模块10212的分析结果，可以将北向请求按照统一的模型编排为网元对应的南向请求。
南向请求处理模块1022包括南向报文构建模块10221和南向报文发送模块10222。其中，南向报文构建模块10221根据与网元对应的南向协议，将南向请求构建为对应的南向报文，并按照一定的顺序形成南向报文序列；南向报文发送模块10222通过NMS或SDN控制器102的南向接口向各个网元103下发南向报文序列中的各个南向报文。
网元103中存储有配置数据，可以根据接收到的南向报文更新对应的配置数据，完成对网元的参数配置。
当向网元发送的南向报文是根据同一个北向请求生成的南向报文时，若其中一个或多个南向报文处理不成功，例如南向报文的下发不成功，或者根据南向报文更新网元的配置数据不成功，此时说明对对北向请求的执行不成功，可以将网元中根据南向报文更新了的配置数据恢复为更新前的状态，以便重新执行该北向请求。
传统技术通过对网元中更新了的配置数据执行逆操作来使配置数据恢复到更新之前的状态，而用于指示执行逆操作的逆操作报文是通过手动编写的方式生成的，通常需要技术人员在程序中，找到对应于每个网元的操作类型和操作数据，判断将更新了的配置数据恢复到更新之前所需要执行的逆操作的操作类型和操作数据，手动生成逆操作报文，这种逆操作报文的生成方式不仅使开发效率低下，同时手动编写容易出现错误。
为了解决上述问题，本申请实施例提供了一种报文的生成方法，可以自动生成与南向报文对应的逆操作报文。具体的，可以先获取业务服务器发送的北向请求，并根据北向请求生成南向报文序列。针对每个南向报文，分别根据其中包括的第一操作指令，确定对应的第二操作指令的操作类型和操作数据，其中，第一操作指令为对与南向报文对应的网元的配置数据进行更新的指令，第二操作指令为第一操作指令的逆操作指令。最后，根据第二操作指令的操作类型和第二指令的操作数据生成逆操作报文。在检测到有南向报文处理不成功时，可以通过向处理成功的网元下发对应的逆操作报文来使网元配置数据进行恢复，即使经过第一操作指令指示更新的网元的配置数据恢复到更新之前状态，从而提高开发效率，同时提高配置数据更新的准确性。
参见图2所示，为本申请实施例提供的报文的生成方法流程图，该方法可以应用于NMS或SDN控制器，具体的，该方法可以包括以下步骤：
S201，获取业务服务器发送的北向请求，并根据北向请求生成南向报文序列。
如前文所述，在获取到业务服务器发送的北向请求后，可以先对获取到的北向请求进行分析，来确定北向请求的类型、涉及的网元和对应各个网元的操作等，根据分析结果可以生成南向请求序列，根据南向请求序列和南向协议可以构建南向报文序列。由于北向请求至少涉及一个网元，则对应的南向报文序列包括至少一个南向报文。南向报文序列是至少一个南向报文按照特定的顺序形成的序列。南向报文可以通过南向接口下发至对应的网元。在向各个网元发送南向报文时，通常按照南向报文序列的顺序进行发送。
每个网元可以对应于至少一个南向报文，对应于同一个网元的多个南向报文之间可以具有一定的依赖关系，也可以相互独立，在此不做限定。具有依赖关系的含义是指需要先执行某个南向报文，基于执行结果再执行另外一个南向报文。
在本实施例中，每个南向报文都包括第一操作指令，第一操作指令为对南向报文对应的网元的配置数据进行更新的指令，例如第一操作指令可以指示网元删除、新增和/或修改某一项或某几项配置数据。在NMS或SDN控制器完成南向报文序列的构建后，可以将各个南向报文下发至对应的网元，网元在接收到南向报文后，可以执行南向报文中的第一操作指令，根据南向报文中的第一操作指令对网元中的配置数据进行 更新。为了描述清楚，在本实施例中，将更新前的网元配置数据称为原始配置数据；将更新后的网元配置数据称为目标配置数据。也就是说，第一操作指令用于指示将原始配置数据A更新为目标配置数据B，对应的第二操作指令则用于指示将执行第一操作指令生成的目标配置数据B恢复到更新前的原始配置数据A。
第一操作指令的操作类型可以包括合并操作、替代操作、删除操作和新增操作等多种操作中的至少一种。第一操作指令的操作数据、原始配置数据以及目标配置数据可以携带有数据标识。
下面对第一操作指令的操作类型和操作数据进行示例性说明。
合并操作指示将网元的配置数据与第一操作指令的操作数据进行合并，即新增第一操作指令的操作数据中存在而原始配置数据中不存在的配置数据，和/或，将原始配置数据修改为第一操作指令的操作数据。具体实现时，可以通过辨别第一操作指令的操作数据的数据标识是否与原始配置数据的数据标识相同，来判断合并操作的实质具体是新增操作还是修改操作。若第一操作指令的操作数据包括数据标识为n的配置数据m，原始配置数据中包括数据标识为n的配置数据k，且配置数据m不同于配置数据k，则通过合并操作将配置数据k修改为配置数据m，得到目标配置数据；若原始配置数据中不存在数据标识n，也就不存在数据标识为n的配置数据m，则通过合并操作新增数据标识为n的配置数据m、及其携带的数据标识n，得到目标配置数据。
举例来说，参考图3所示，该图为根据第一操作指令的操作数据302，将网元的原始配置数据301更新为目标配置数据303的示意图。在该图中，网元的原始配置数据301、第一操作指令的操作数据302和目标配置数据303都是以树形结构呈现的，在以下附图中上述三种数据均以树形结构呈现，不再重复说明。
其中，网元的原始配置数据301，其树形结构的根节点为a，下有三个子节点a1、a2和a3，为了方便说明，可以用/a/a1、/a/a2和/a/a3表示，a1节点下有两个二级子节点a11和a12，为了便于说明，可以用/a/a1/a11和/a/a1/a12表示。第一操作指令的操作数据302，其树形结构的根节点为a，下有三个子节点a1、a2′和a4，可以用/a/a1、/a/a2′和/a/a3表示，a1节点下有两个二级子节点a11′和a13，可以用/a/a1/a11′和/a/a1/a12，其中，/a/a2′是与/a/a2具有相同数据标识的不同配置数据，/a/a1/a11′是与/a/a1/a11具有相同数据标识的不同配置数据。
假设第一操作指令的操作类型为合并操作。首先比较第一操作指令的操作数据302和网元的原始配置数据301，确定原始配置数据301中不存在第一操作指令的操作数据302中/a/a4和/a/a1/a13，但存在与/a/a2′具有相同数据标识的不同配置数据/a/a2，且存在与/a/a1/a11′具有相同数据标识的不同配置数据/a/a1/a11，因此对第一操作指令的执行过程即为，增加/a/a4和/a/a1/a13，且将/a/a2和/a/a1/a11对应修改为/a/a2′和/a/a1/a11′。若对原始配置数据301执行第一操作指令，可以得到目标配置数据303，其树形结构的根节点为a，下有四个子节点a1、a2′、a3和a4，其中a1下有三个二级子节点a11′、a12和a13，完成原始配置数据301与第一操作指令的操作数据302的合并。
替代操作指示将网元的原始配置数据替换为第一操作指令的操作数据。具体实现时，网元接收到操作类型是替代操作的第一操作指令后，可以执行第一操作指令，以 将第一操作指令的操作数据作为网元的目标配置数据替换原始配置数据。
举例来说，参考图4所示，该图为根据第一操作指令的操作数据402，将网元的原始配置数据401修改为目标配置数据403的示意图。在该图中，网元的原始配置数据401包括/a/a1/a11、/a/a1/a12、/a/a2和/a/a3；第一操作指令的操作数据402包括/a/a1/a11′、/a/a1/a13、/a/a2′和/a/a4。其中，/a/a1/a11′和/a/a1/a11是数据标识相同的不同配置数据，/a/a2′和/a/a2也是数据标识相同过的不同配置数据。假设第一操作指令的操作类型为替代操作，那么通过执行第一操作指令，可以将原始配置数据401替代为第一操作指令的操作数据402，即目标配置数据403包括/a/a1/a11′、/a/a1/a13、/a/a2′和/a/a4。上述替代操作的实质是将原始配置数据中的/a/a1/a11修改为/a/a1/a11′，将原始配置数据中的/a/a1/a12删除，增加了配置数据/a/a1/a13，将原始配置数据中的/a/a2修改为/a/a2′，删除了配置数据/a/a3，以及增加了配置数据/a/a。
删除操作指示将网元的原始配置数据中与第一操作指令的操作数据相同的配置数据删除。
举例说明，如图5所示，该图为根据第一操作指令的操作数据502，将网元的原始配置数据501修改为目标配置数据503的示意图。在该图中，网元的原始配置数据501，根节点为a，下有三个子节点a1、a2和a3，其中a1下有两个二级子节点a11和a12。也就是说，原始配置数据501包括配置数据/a/a1/a11、/a/a1/a12、/a/a2和/a/a3。第一操作指令的操作类型为删除操作，第一操作指令的操作数据502包括/a/a1/a12。根据第一操作指令对网元的原始配置数据501进行更新，即删除二级节点a12，得到的目标配置数据503包括/a/a1/a11、/a/a2和/a/a3。
新增操作指示将第一操作指令的操作数据新增至网元的配置数据中。
举例说明，如图6所示，该图为根据第一操作指令的操作数据602，将网元的原始配置数据601修改为目标配置数据603的示意图。在该图中，网元的原始配置数据601，根节点为a，下有三个子节点a1、a2和a3，a1节点下有两个二级子节点a11和a12。即原始配置数据601包括/a/a1/a11、/a/a1/a12、/a/a2和/a/a3。第一操作指令的操作类型为新建操作，第一操作指令的操作数据602包括/a/a1/a13。对网元的原始配置数据601根据第一操作指令进行更新，即新增一级节点a1下的二级节点a13，得到的目标配置数据603包括/a/a1/a11、/a/a1/a12、/a/a1/a13、/a/a2和/a/a3。
S202，针对每个南向报文，分别根据第一操作指令确定第二操作指令的操作类型和第二操作指令的操作数据。
在本实施例中，针对每个南向报文，可以分别根据第一操作指令确定第二操作指令的操作类型和第二操作指令的操作数据。其中，第二操作指令为第一操作指令的逆操作指令，逆操作指令中的逆操作是能够使经过第一操作指令指示更新的网元配置数据恢复到更新之前状态的操作。
在本实施例中，提供两种根据第一操作指令确定第二操作指令的操作类型和第二操作指令的操作数据的确定方式，当然，这两种方式并不是构成对本申请的限定。
作为一种可能的实施方式，对第二操作指令的操作类型和第二操作指令的操作数据的确定方式，可以具体为，NMS或SDN控制器获取南向报文对应网元的原始配置数据，对原始配置数据执行第一操作指令生成目标配置数据，通过将原始配置数据和 目标配置数据进行比对，来得到第二操作指令的操作类型和第二操作指令的操作数据。其中，获取南向报文对应网元的原始配置数据，具体的，可以由NMS或SDN控制器向南向报文对应网元发送原始配置数据获取请求，网元在接收到原始配置数据获取请求之后，向NMS或SDN控制器发送存储在该网元中的原始配置数据。
当NMS或SDN控制器获取到存储在网元中的原始配置数据之后，将执行第一操作指令生成的目标配置数据与原始配置数据进行比对，以确定出相对于原始配置数据而言，目标配置数据是增加了配置数据、减少了配置数据还是修改了配置数据，从而根据具体情况确定对应的第二操作指令的操作类型和操作数据。
作为另一可能的实施方式，可以直接根据第一操作指令的操作类型和第一操作指令的操作数据，来确定对应于第一操作指令的第二操作指令的操作类型和第二操作指令的操作数据。例如若第一操作指令的操作类型为删除操作，则第二操作指令的操作类型可以为新增操作，第二操作指令的操作数据与第一操作指令的操作数据相同；若第一操作指令的操作类型为新增操作，则第二操作指令的操作类型可以为删除操作，第二操作指令的操作数据与第一操作指令的操作数据相同。此外，若第一操作指令的操作类型为合并操作，那么第二操作指令的操作类型可以是合并操作和/或删除操作，其操作数据可根据第一操作指令和原始配置数据而定。若第一操作指令的操作类型为替代操作，那么第二操作指令的操作类型可以是替代操作、合并操作、删除操作或新增操作中的一种或多种，其操作数据可根据第一操作指令而定，也可以根据第一操作指令和原始配置数据而定。
在本申请实施例中，第一操作指令和第二操作指令可以不只包括一种操作类型，在获取第二操作指令的操作类型和操作数据时，可以针对具体情况一一进行，例如第一操作指令用于删除配置数据C，同时增加配置数据D，则相应的第二操作指令可用于新增配置数据C，同时删除配置数据D。
关于上述两种实现方式的具体示例，请参见后文。
S203，根据第二操作指令的操作类型和第二操作指令的操作数据生成逆操作报文。
由于逆操作是用于将目标配置数据恢复至原始配置数据的操作，因此逆操作报文是用于将目标配置数据恢复至原始配置数据的报文。逆操作报文的生成主要是为了在南向报文的处理结果为处理失败时能够将目标配置数据恢复至原始配置数据。
作为一种可能的实施方式，逆操作报文的生成时间可以在南向报文生成后立即进行，在有南向报文的处理结果为处理失败时，向执行第一操作指令成功的网元发送生成的逆操作报文，以进行配置数据的恢复。
作为另一种可能的实施方式，也可以在南向报文生成后获取第二操作指令的操作类型和第二操作指令的操作数据，在判断有南向报文的处理结果为处理失败时，再生成南向报文，并向执行第一操作指令成功的网元发送生成的逆操作报文，以进行网元配置数据的恢复。
在本申请实施例中，网元对南向报文的处理结果可以是接收南向报文、解析南向报文、和执行南向报文其中一种或多种处理是否成功的结果。若没有接收到南向报文、解析南向报文失败或执行南向报文中的第一操作指令失败，则认为对南向报文的处理 结果为处理失败；反之，则认为处理成功。
若有任意一个南向报文的处理结果为处理失败，则向处理结果为成功的网元发送对应的逆操作报文。具体的，可以按照南向报文序列的逆序发送逆操作报文。当对应于同一个网元的多个南向报文有一定的依赖关系时，按照南向报文序列的逆序发送逆操作报文，可以保证数据恢复的正确性。
举例来说，如图7所示，该图为南向报文序列和逆操作报文序列的示意图。其中，南向报文形成南向报文序列，逆操作报文形成逆操作报文序列，南向报文的下发可以按照南向报文序列顺序进行，具体的，按照南向报文1、南向报文2、南向报文3、……、南向报文n的顺序进行下发。在南向报文的下发过程中，当下发了某个南向报文并接收到与该南向报文对应的处理结果之后，再决定是否下发下一个南向报文。即如果处理结果为成功，则下发下一个南向报文；如果处理结果为不成功，则不下发下一个南向报文，并且向之前下发的处理成功的南向报文对应的网元发送逆操作报文。例如完成南向报文5的发送后，得到的南向报文5的处理结果为处理失败，此时可以停止南向报文6及后续南向报文的发送，并向南向报文1、南向报文2、南向报文3和南向报文4对应的网元发送对应的逆操作报文，逆操作报文的发送可以按照南向报文序列的逆序发送，即按照逆操作报文4、逆操作报文3、逆操作报文2和逆操作报文1的顺序依次发送逆操作报文。
本申请实施例提供的报文的生成方法中，先获取业务服务器发送的北向请求，并根据北向请求生成南向报文序列，每个南向报文均包括第一操作指令，用于对网元配置数据进行更新，然后可以针对每个南向报文的第一操作指令，确定对应的第二操作指令的操作类型和第二操作指令的操作数据，其中，第二操作指令为第一操作指令的逆操作指令，用于将经过第一操作指令指示更新的网元的配置数据恢复到更新之前的状态，最后根据第二操作指令的操作类型和第二操作指令的操作数据生成逆操作报文。通过南向报文的第一操作指令来自动生成对应于第一操作指令的逆操作报文，不需要其他业务模块的参与，也不需要人工编写，当其中任意一个南向报文处理不成功时，可以通过下发逆操作报文来使网元配置参数进行更新，使经过第一操作指令指示更新的网元的配置数据恢复到更新之前状态，从而提高开发效率，同时提高数据更新的准确性。
为了便于理解，下面就S202中，根据第一操作指令确定第二操作指令的操作类型和第二操作指令的操作数据的两种可能的实现方式进行详细说明。
本申请实施例中，可以将原始配置数据和目标配置数据进行比对，来确定将目标配置数据恢复为原始配置数据的第二操作指令的操作类型和第二操作指令的操作数据。
作为一种可能的实施方式，原始配置数据包括第一配置数据和第一配置数据的标识，目标配置数据包括第二配置数据和第二配置数据的标识。将原始配置数据和目标配置数据进行比对，若比对结果是，第一配置数据的配置标识与第二配置数据的配置标识相同，且第一配置数据和第二配置数据不同，则可认为网元需要根据第一操作指令将第一配置数据修改为第二配置数据。此时可以确认第二操作指令的作用在于将网元目标配置数据中第二配置数据修改为第一配置数据，则第二操作指令的操作类型是 合并操作，第二操作指令的操作数据包括第一配置数据和第一配置数据的标识。
举例来说，参考图8所示，该图为根据原始配置数据801和目标配置数据802，确定第二操作指令的操作数据803的示意图。在该图中，网元的原始配置数据801，根节点为a，下有三个子节点a1、a2和a3，a1节点下有两个二级子节点a11和a12。网元的目标配置数据802：根节点为a，下有三个子节点a1、a2′和a3，a1节点下有两个二级子节点a11′和a12。其中，由于/a/a2′是与/a/a2具有相同数据标识的不同配置数据，/a/a1/a11′是与/a/a1/a11具有相同数据标识的不同配置数据，所以可以确定第二操作指令的作用在于将目标配置数据802中的/a/a1/a11′修改为/a/a1/a11，且将/a/a2′修改为/a/a2，因此第二操作指令的操作类型可以是合并操作，第二操作指令的操作数据803包括/a/a1/a11和/a/a2。
当然，第二操作指令的操作类型还可以是删除操作和新增操作，例如删除/a/a1/a11′和/a/a2′，且新增/a/a1/a11和/a/a2，即对应删除操作的操作数据为/a/a1/a11′和/a/a2′，对应新增操作的操作数据为/a/a1/a11和/a/a2，可与上述合并操作实现同样的效果。
作为另一种可能的实施方式，若原始配置数据和目标配置数据的比对结果是，原始配置数据包括第三配置数据和第三配置数据的标识，且目标配置数据中不存在第三配置数据和第三配置数据的标识，则可认为网元根据第一操作指令将第三配置数据和第三配置数据的标识删除，此时可以确认第二操作指令的作用在于在网元目标配置数据中存储第三配置数据和第三配置数据的标识，则第二操作指令的操作类型可以是新增操作，第二操作指令的操作数据包括第三配置数据和第三配置数据的标识。
举例来说，参考图9所示，该图为根据原始配置数据901和目标配置数据902，确定第二操作指令的操作数据903的示意图。在该图中，网元的原始配置数据901包括/a/a1/a11、/a/a1/a12、/a/a2和/a/a3，目标配置数据902存在原始配置数据901中除/a/a1/a12外的其他配置数据，即通过删除原始配置数据901中的/a/a1/a12得到目标配置数据902，所以可以确定第二操作指令的作用在于在目标配置数据902中增加/a/a1/a12，因此第二操作指令的操作类型可以是新增操作，第二操作指令的操作数据903包括/a/a1/a12。
当然，第二操作指令的操作类型还可以是合并操作，第二操作指令的操作数据包括第三配置数据和第三配置数据的标识，例如包括/a/a1/a12，即将/a/a1/a12与目标配置数据902进行合并，以便得到原始配置数据901。
作为又一种可能的实施方式，若原始配置数据和目标配置数据的比对结果是，目标配置数据包括第四配置数据和第四配置数据的标识，且原始配置数据中不存在第四配置数据和第四配置数据的标识，则可认为网元根据第一操作指令新增第四配置数据和第四配置数据的标识，此时可以确认第二操作指令的作用在于删除网元目标配置数据中存储的第四配置数据和第四配置数据的标识，则第二操作指令的操作类型可以是删除操作，第二操作指令的操作数据包括第四配置数据和第四配置数据的标识。
举例来说，参考图10所示，该图为根据原始配置数据1001和目标配置数据1002，确定第二操作指令的操作数据1003的示意图。在该图中，原始配置数据1001包括/a/a1/a11、/a/a1/a12、/a/a2和/a/a3，目标配置数据1002不仅存在原始配置数据1001中的全部配置数据，且还存在原始配置数据1001中不存在的配置数据/a/a1/a13，即通 过在原始配置数据1001中增加/a/a1/a13得到目标配置数据1002，所以可以确定第二操作指令的作用在于将目标配置数据1002中删除/a/a1/a13，因此第二操作指令的操作类型可以是删除操作，第二操作指令的操作数据1003：/a/a1/a13。
通过对原始配置数据执行第一操作指令，并将原始配置数据和目标配置数据进行比对，根据比较结果可以确定第二操作指令的作用，从而直接确定第二操作指令的操作类型和第二操作指令的操作数据，从而提高逆操作报文的生成效率。
为了便于理解，下面就S202中，根据第一操作指令确定第二操作指令的操作类型和第二操作指令的操作数据的另一种可能的实现方式进行详细说明。
由于第二操作指令为第一操作指令的逆操作，在本申请实施例中，还可以直接根据第一操作指令的操作类型和操作数据，例如根据第一操作指令是合并、替代、删除和新增中的一种或多种操作类型，来确定与第一操作指令对应的第二操作指令的操作类型和第二操作指令的操作数据，例如合并操作的逆操作可以是合并操作和/或删除操作，替代操作的逆操作可以是替代操作、合并操作、删除操作或新增操作的一种或多种，删除操作的逆操作是新增操作，新增操作的逆操作是删除操作。
作为一种可能的实施方式，若第一操作指令的操作类型包括合并操作，则获取南向报文对应网元的原始配置数据，根据原始配置数据和合并操作的操作数据，确认第二操作指令的操作类型和第二操作指令的操作数据。
合并操作的介绍可以参见S202，在此不再赘述。由于合并操作通常是在原始配置数据中，修改与第一操作指令的操作数据标识相同的配置数据，且新增原始配置数据中没有而第一操作指令的操作数据中包括的数据标识及其配置数据。因此对应于合并操作的第二操作指令的操作类型可以是合并操作，也可以是删除操作，还可以是合并操作和删除操作的组合，具体的，可以根据原始配置数据和合并操作的操作数据来确定。第二操作指令的操作数据可以根据原始配置数据和合并操作的操作数据来对应确定。
具体的，假设获取的南向报文对应网元的原始配置数据包括第五配置数据和第五配置数据的标识，第一操作指令为合并操作，该合并操作的操作数据包括第六配置数据和第六配置数据的标识。若第五配置数据的标识和第六配置数据的标识相同，且第五配置数据和第六配置数据不同，则可认为第一操作指令指示网元将第五配置数据修改为第六配置数据，此时可以确定第二操作指令的作用在于将网元目标配置数据中第六配置数据修改为第五配置数据，则第二操作指令的操作类型是合并操作，第二操作指令的操作数据为第五配置数据和第五配置数据的标识。
举例来说，参考图11所示，该图为根据原始配置数据1101和第一操作指令的操作数据1102，确定第二操作指令1103的示意图。在该图中，网元的原始配置数据1101中包括/a/a1/a11，第一操作指令的操作类型为合并操作，该合并操作的操作数据1102包括/a/a1/a11′，其中/a/a1/a11′是和/a/a1/a11具有相同数据标识的不同配置数据，则可认为第一操作指令指示网元将/a/a1/a11修改为/a/a1/a11′，此时可以确定第二操作指令用于将/a/a1/a11′修改为/a/a1/a11，则第二操作指令的操作类型为合并操作，第二操作指令的操作数据1103：/a/a1/a11。
当然，第二操作指令的操作类型还可以是删除操作和新增操作，例如删除/a/a1/a11′，且新增/a/a1/a11，即对应删除操作的操作数据为/a/a1/a11′，对应新增操作的操作数据为/a/a1/a11，可与上述合并操作实现同样的效果。
具体的，若第一操作指令的操作类型为合并操作，该合并操作的操作数据包括第七配置数据和第七配置数据的标识，且原始配置数据中不存在第七配置数据和第七配置数据的标识，则可认为第一操作指令指示网元在原始配置数据中增加第七配置数据和第七配置数据的标识，此时可以确认第二操作指令的作用在于删除网元目标配置数据中存储的第七配置数据和第七配置数据的标识，则第二操作指令的操作类型是删除操作，第二操作指令的操作数据包括第七配置数据和第七配置数据的标识。
举例来说，参考图12所示，该图为根据原始配置数据1201和第一操作指令的操作数据1202，确定第二操作指令1203的示意图。在该图中，第一操作指令的操作类型为合并操作，该合并操作的操作数据1202为：/a/a1/a13，且原始配置数据1201中不存在/a/a1/a13，则可认为第一操作指令指示网元在原始配置数据1201中新增/a/a1/a13，此时可以确认第二操作指令用于删除/a/a1/a13，则第二操作指令的操作类型为删除操作，第二操作指令的操作数据1203为：/a/a1/a13。
具体的，若原始配置数据包括第五配置数据和第五配置数据的标识，且不存在第七配置数据和第七配置数据的标识。第一操作指令的操作类型为合并操作，该合并操作的操作数据包括第六配置数据和第六配置数据的标识、第七配置数据和第七配置数据的标识。若第五配置数据的标识和第六配置数据的标识相同，且第五配置数据和第六配置数据不同，则可认为第一操作指令指示网元将第五配置数据修改为第六配置数据，并新增第七配置数据和第七配置数据的标识。此时可以确定第二操作指令用于将第六配置数据修改为第五配置数据，并删除第七配置数据和第七配置数据的标识，则第二操作指令的操作类型为合并操作和删除操作，合并操作的操作数据为第五配置数据和第五配置数据的标识，删除操作的操作数据为第七配置数据和第七配置数据的标识。
举例来说，参考图13所示，该图为根据原始配置数据1301和第一操作指令的操作数据1302，确定第二操作指令1303的示意图。在该图中，原始配置数据1301根节点为a，下有三个子节点a1、a2和a3，a1节点下有两个二级子节点a11和a12。第一操作指令为合并操作，该合并操作的操作数据1302为：/a/a2′、/a/a4、/a/a1/a11′和/a/a1/a13，其中，/a/a1/a11′是和/a/a1/a11是具有相同数据标识的不同配置数据，/a/a2′是和/a/a2是具有相同数据标识的不同配置数据。判断第一操作指令是指示网元将/a/a1/a11修改为/a/a1/a11′，将/a/a2修改为/a/a2′，且新增/a/a1/a13和/a/a4，此时可以确定第二操作指令用于将目标配置数据/a/a1/a11′修改为/a/a1/a11，将/a/a2′修改为/a/a2，删除/a/a1/a13和/a/a4，第二操作指令的操作类型为合并操作和删除操作，合并操作对应的操作数据1303为/a/a1/a11和/a/a2，删除操作对应的操作数据1304为/a/a1/a13，删除操作对应的操作数据1305为/a/a4。
作为另一种可能的实施方式，若第一操作指令的操作类型包括替代操作，则获取南向报文对应网元的原始配置数据，并确定第二操作指令的操作类型为包括替代操作，第二操作指令的操作数据包括原始配置数据，替代操作用于将网元中存储的配置数据 替代为原始配置数据。
举例来说，参考图14所示，该图为根据原始配置数据1401和第一操作指令的操作数据1402，确定第二操作指令1403的示意图。在该图中，第一操作指令的操作类型包括替代操作，第一操作指令的操作数据为1402，则第二操作指令的操作类型为替代操作，第二操作指令的操作数据1403为原始配置数据1401，用于将目标配置数据恢复为原始配置数据1401。
在本申请实施例中，还可以根据原始配置数据和第一操作指令的操作数据，对替代操作引起的数据变化进行分析，对于图15的原始配置数据1501和第一操作指令1502，可以判断第一操作指令指示网元将/a/a1/a11修改为/a/a1/a11′，将/a/a2修改为/a/a2′，新增/a/a1/a13和/a/a4，因此相应的逆操作可用于将/a/a1/a11′修改为/a/a1/a11，将/a/a2′修改为/a/a2，删除/a/a1/a13和/a/a4，即替代操作的逆操作可以是合并操作和删除操作，具体的，合并操作的操作数据1503为/a/a1/a11和/a/a2，删除操作的操作数据1504为/a/a1/a13，删除操作的操作数据1505为/a/a4。
作为又一种可能的实施方式，若第一操作指令的操作类型包括删除操作，则确定第二操作指令的操作类型为包括新增操作，第二操作指令的操作数据包括新增操作的操作数据，新增操作用于在网元中存储新增操作的操作数据。在该实施方式中，第一操作指令的操作类型为删除操作，因此也可以直接根据第一操作指令来确定第二操作指令，而不必获取原始配置数据，不影响本申请实施例的实现。
举例来说，参考图16所示，该图为根据第一操作指令的操作数据1601，确定第二操作指令1602的示意图。在该图中，第一操作指令的操作类型为删除操作，第一操作指令的操作数据1601为：/a/a1/a12，则第二操作指令的操作类型为新增操作，该新增操作的操作数据1602与第一操作指令的操作数据1601相同，即为/a/a1/a12。
当然，第二操作指令的操作类型还可以是合并操作，第二操作指令的操作数据与第一操作指令的操作数据相同，例如包括/a/a1/a12，即将/a/a1/a12与目标配置数据进行合并，以便实现目标配置数据向原始配置数据的恢复。
作为又一种可能的实施方式，若第一操作指令的操作类型包括新增操作，则确定第二操作指令的操作类型为包括删除操作，第二操作指令的操作数据包括新增操作的操作数据，删除操作用于删除在网元中存储的新增操作的操作数据。在该实施方式中，第一操作指令的操作类型为删除操作，因此也可以直接根据第一操作指令来确定第二操作指令，而不必获取原始配置数据，不影响本申请实施例的实现。
举例来说，参考图17所示，该图为根据第一操作指令的操作数据1701，确定第二操作指令1702的示意图。在该图中，第一操作指令的操作类型为新增操作，第一操作指令的操作数据1701为：/a/a1/a13，则第二操作指令的操作类型为删除操作，该删除操作的操作数据1702与第一操作指令的操作数据1701相同，即为/a/a1/a13。
