步骤102，获取在SDN控制器中存储的网络设备的告警信息，记为第二告警信息。
在一实施中，SDN控制器中所存储的网络设备的告警信息存储在告警管理模块中，告警管理模块中的告警信息是网络设备主动上报给设备管理模块，设备管理模块再上报给设备告警监控模块，设备告警监控模块再上报给告警管理模块的。
在一实施中，无论信息恢复组件内嵌于SDN控制器中还是外置于第三方组件，信息恢复组件在触发信息恢复之后，都会向SDN控制器内部的告警管理模块发送指令，该指令中携带有网络设备标识，告警管理模块根据网络设备标识返回相对应的网络设备的告警信息，并记为第二告警信息。
步骤103，将第一告警信息与第二告警信息进行匹配，获取匹配结果。
在一实施中，告警信息中包括告警网络设备、告警源模块、告警产生时间、告警原因等信息。
在一实施中，可以将第一告警信息和第二告警信息输入到预先训练好的匹配模型中进行匹配，也可以直接采用信息匹配算法对第一告警信息和第二告警信息进行匹配；若第一告警信息和第二告警信息完全一致，则相对应的匹配结果为第一告警信息和第二告警信息匹配；若第一告警信息和第二告警信息存在不一致的情况，则相对应的匹配结果为第一告警信息和第二告警信息不完全匹配，此时的匹配结果中还包含有没有匹配上的告警信息。
在一实施中，以SDN控制器中存储的第二告警信息包括告警信息A、告警信息B和告警信息C；网络设备中存储的第一告警信息同样也包含告警信息A、告警信息B和告警信息C为例，说明第一告警信息和第二告警信息不完全匹配的原因有以下两种情况：
(1)、网络设备在某刻产生清除告警信息和故障告警信息(如清除告警信息A和故障告警信息D)，此时应当上传至SDN控制器的告警管理模块中，由SDN控制器的告警管理模块对第二告警信息自动进行恢复；但由于SDN控制器内部异常(如设备管理模块和设备告警监控模块的通信中断)，导致网络设备在某刻产生清除告警信息A和新增告警信息D并没有上传给告警管理模块；此时的网络设备并不知晓SDN控制器的告警管理模块未接收到其上传的清除告警信息A和新增告警信息D，且SDN控制器的告警管理模块也并不知晓网络设备上传了清除告警信息A和新增告警信息D；就会导致SDN控制器的告警管理模块存储的网络设备的告警信息(告警信息A、告警信息B和告警信息C)会与网络设备的告警信息(告警信息B、告警信息C和告警信息D)不一致。
(2)、当网络设备发生异常掉线后，无法与SDN控制器进行通信，也就是说网络设备在异常期间产生的清除告警信息A和新增告警信息D无法发送给SDN控制器的设备管理模块； 而网络设备在恢复正常重新上线后，此时只能够将重新上线之后网络设备产生的清除告警信息和故障告警信息(如故障告警信息E)发送给SDN控制器，SDN控制器就无法知晓网络设备在异常时间中所产生的清除告警信息和故障告警信息，就会导致SDN控制器的告警管理模块存储的网络设备的告警信息(告警信息A、告警信息B、告警信息C和告警信息E)会与网络设备的告警信息(告警信息B、告警信息C、告警信息D和告警信息E)不一致。
步骤104，当匹配结果为第一告警信息和第二告警信息不完全匹配时，根据匹配结果对第二告警信息进行恢复。
在一实施中，当匹配结果表明第一告警信息和第二告警信息不完全匹配时，从匹配结果中获取新增告警信息和清除告警信息；新增告警信息是指第一告警信息中包含但第二告警信息中不包含的告警信息，也就是第一告警信息中与第二告警信息匹配失败的告警信息；清除告警信息是指第一告警信息中不包含但第二告警信息中包含的告警信息，也就是第二告警信息中与第一告警信息匹配失败的告警信息。
在一实施中，对第二告警信息进行恢复，就是将匹配结果中的新增告警信息增加至第二告警信息中，将第二告警信息中与清除告警信息对应的告警信息进行删除。
在一实施中，当匹配结果表明第一告警信息和第二告警信息完全匹配时，说明SDN控制器中告警管理模块存储的网络设备的告警信息和网络设备处存储的网络设备的告警信息完全一致，不需要对SDN控制器中告警管理模块存储的网络设备的告警信息进行恢复处理。
本公开实施例，在信息恢复的过程中，获取与SDN控制器通信的网络设备内存储的网络设备的告警信息，记为第一告警信息；获取在SDN控制器中存储的网络设备的告警信息，记为第二告警信息；将第一告警信息与第二告警信息进行匹配，获取匹配结果；当匹配结果为第一告警信息和第二告警信息不完全匹配时，根据匹配结果对第二告警信息进行恢复。通过SDN控制器或网络设备在异常恢复之后，将网络设备内存储的告警信息和SDN控制器内存储的网络设备的告警信息进行匹配，并根据匹配结果对SDN控制器中存储的网络设备的告警信息进行恢复，从而实现SDN控制器侧的告警信息和网络设备侧的告警信息自动保持一致；解决了现有技术中由于SDN控制器或网络设备异常，网络设备侧产生的故障告警信息或清除告警消息无法及时地上报给SDN控制器，从而导致的SDN控制器侧的告警信息和网络设备侧的告警信息不一致的问题。
本公开的一个实施方式涉及一种信息恢复方法，应用在一个信息恢复组件中，该信息恢复组件可以内嵌于SDN控制器内部；也可以外置于第三方组件中，独立于SDN控制器和网络设备存在，如图2所示，包括：
步骤201，向用户发送与所述SDN控制器通信的各网络设备的网络设备标识，并接收用户发送的指定网络设备标识。
在一实施中，当用户需要确认SDN控制器侧的网络设备的告警信息和网络设备侧的网络设备的告警信息是否一致时，可以手动触发信息恢复组件的启动机制，信息恢复组件在被用户触发之后，会在人机交互界面上显示与SDN控制器进行通信的所有网络设备的网络设备标识，对于每一个网络设备标识还可以显示由该网络标识对应的告警源模块标识；并接收用户返回的指定网络设备标识，同时，所接收的指定网络设备标识中还可以包含指定告警源模块标识。
步骤202，从与指定网络设备标识对应的网络设备中获取网络设备的告警信息，记为第 一告警信息。
在一实施中，信息恢复组件在接收到用户返回的指定网络设备标识之后，会将根据该指定网络设备标识生成一个信息获取指令发送给SDN控制器的设备告警监控模块，由设备告警监控模块将信息获取指令发送给设备管理模块，设备管理模块接收到信息获取指令之后，根据信息获取指令中携带的指定网络设备标识主动从与指定网络设备标识对应的网络设备中获取网络设备的告警信息，并返回给设备告警监控模块，由设备告警监控模块发送给信息恢复组件，信息恢复组件将其记为第一告警信息。
步骤203，获取在SDN控制器中存储的网络设备的告警信息，记为第二告警信息。
在一实施中，本步骤与本公开实施例的步骤102大致相同，此处不一一赘述。
步骤204，将第一告警信息与第二告警信息进行匹配，获取匹配结果。
在一实施中本步骤与本公开实施例的步骤103大致相同，此处不一一赘述，
步骤205，当匹配结果为第一告警信息和第二告警信息不完全匹配时，根据匹配结果对第二告警信息进行恢复。

本公开的实施方式，在其他实施方式的基础之上还可以由运维人员随时进行手动对账操作，比对出SDN控制器侧和网络设备侧不一致的告警信息，并进行自动化恢复。解决了因为SDN控制器内部上报的告警消息丢失，从而导致的SDN控制器侧的网络设备的告警信息和网络设备侧的网络设备的告警信息不一致的问题。同时，告警对账组件的手动对账功能可以指定对账的设备、告警源模块，也可以不指定任何信息进行全量对账，大大增强了本公开的灵活性。
本公开的一个实施方式涉及一种信息恢复方法，应用在一个信息恢复组件中，该信息恢复组件可以内嵌于SDN控制器内部；也可以外置于第三方组件中，独立于SDN控制器和网络设备存在，如图3所示，包括：
步骤301，接收与SDN控制器通信的网络设备的设备上线消息，其中，设备上线消息中携带有网络设备标识。
在一实施中，网络设备发生异常掉线，当网络设备恢复正常后，会主动与SDN控制器建立链接，SDN控制器的设备管理模块在监测到与网络设备成功建立链接时，设备管理模块便认为监听到网络设备的上线消息(在设备管理模块将网络设备的状态由离线更改为在线)，此时，设备管理模块生成网络设备的设备上线消息，并发送给信息恢复组件，信息恢复组件在被设备上线消息触发之后，会启动信息恢复流程，进行SDN控制器侧的网络设备的告警信息和网络设备侧的网络设备的告警信息是否一致的确认。
在一实施中，当网络设备与SDN控制器通过南向协议建立通信链路后，SDN控制器和网络设备会同时在该条通信链路上发送保活指令，保证该通信链路一直处于存活状态。如果控制器在保活周期内未接收到网络设备的保活指令，便认为网络设备已下线(在设备管理模块将网络设备的状态由在线更改为离线)。
步骤302，从与网络设备标识对应的网络设备中获取网络设备的告警信息，记为第一告警信息。
在一实施中，信息恢复组件在被设备上线消息触发之后，会将根据该网络设备标识生成一个信息获取指令发送给SDN控制器的设备告警监控模块，由设备告警监控模块将信息获取 指令发送给设备管理模块，设备管理模块接收到信息获取指令之后，根据信息获取指令中携带的网络设备标识主动从与网络设备标识对应的网络设备中获取网络设备的告警信息，并返回给设备告警监控模块，由设备告警监控模块将网络设备的告警信息发送给信息恢复组件，信息恢复组件将其记为第一告警信息。
步骤303，获取在SDN控制器中存储的网络设备的告警信息，记为第二告警信息。
在一实施中，本步骤与本公开实施例的步骤102大致相同，此处不一一赘述。
步骤304，将第一告警信息与第二告警信息进行匹配，获取匹配结果。
在一实施中本步骤与本公开实施例的步骤103大致相同，此处不一一赘述，
步骤305，当匹配结果为第一告警信息和第二告警信息不完全匹配时，根据匹配结果对第二告警信息进行恢复。
