Description

[根据细则26改正30.04.2019]　一种数据处理的方法以及相关设备
本申请要求于2018年3月26日提交中国国家知识产权局、申请号为201810253225.6、发明名称为“一种数据处理的方法以及相关设备”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
本申请涉及通信领域，特别涉及一种数据处理的方法以及相关设备。
背景技术
软件定义网络(software defined network，SDN)中的控制器在管理转发器时包括多种场景，例如，其中一种场景为单头管理，即转发器仅被控制器管理，另一种场景为多头管理，即转发器可以被多个管理设备控制，该多个设备可以包括控制器或其他的管理设备。
当转发器被管理设备独立控制时，控制器和管理设备在交互中产生的数据不一致的场景可以包括多种，例如，转发器重启，但转发器上的配置没有保存、转发器和控制器之间的网络故障或是转发器自身的原因，例如，转发器系统繁忙，又或是控制器的数据库还原、异地容灾场景等，都可能导致转发器和管理设备上的数据不一致。而以上单头管理场景中导致管理设备与转发器之间数据不一致的场景都可以由管理设备或转发器为主进行修复。而多头管理场景下，转发器与管理设备的数据不一致的原因还可能是由于转发器被除该管理设备外的其他管理设备控制，而其他的管理设备下发的数据与该管理设备下发的数据冲突，导致转发器上的数据与该管理设备上的数据不一致。而转发器往往无法确定以管理设备上的数据为主还是以转发器上的数据为主，使数据同步的处理方式复杂，效率低。因此，在多头管理场景下，如何保障管理设备与转发器数据的一致性成为亟待解决的问题。
发明内容

具体实施方式
本申请提供一种数据处理的方法以及相关设备，用于在多头管理的场景下可以更高效灵活地实现管理设备与转发器的数据一致性，提高管理设备与转发器通信的可靠性。
SDN网络是一种可以由软件定义的网络架构，分离了传统网络中交换机的控制平面和数据转发平面，由集中式的管理设备统一管理网络中的转发器。该SDN网络可以包括转发器以及一个或多个用于管理转发器的管理设备。本申请具体网络架构图可以如图1所示，在本申请实施例中的网络架构中，转发器可以由多个管理设备管理，即多头管理场景，该多个管理设备可以包括至少一个控制器或其他一个或多个管理设备，控制器可以是敏捷控制器(agile controller，AC)。具体的管理方式可以是，以一个控制器为例，控制器可以通过为转发器下发数据，包括配置数据、转发数据等，然后控制器通过预置的协议格式与转发器进行数据通信，包括控制器控制转发器对数据进行转发等。在实际应用中，转发器可以由多个管理设 备控制，因此转发器上可能存在多个管理设备的数据，当一个控制器上的数据与转发器上的数据不一致时，转发器无法确定以控制器的数据为主还是以转发器上的数据为主，从而可能导致控制器与转发器的通信失败或转发器无法转发数据等。例如，如图2所示，控制器上的数据与转发器上的数据仅有一部分共有的数据相同，由于转发器可以由其他管理设备控制，其他管理设备可以修改转发器上的数据，因此导致控制器上的数据与转发器上的数据不一致，例如，转发器上的配置数据。为保障管理设备上的数据与转发器上的数据一致性，本申请实施例提供了数据处理的方法。请参阅图3，为本申请实施例提供的一种数据处理方法的一个流程示意图。

第一管理设备对转发器加锁，具体的可以是第一管理设备向转发器发送锁定指令，例如，在第一管理设备需要对转发器进行控制时，首先向转发器发送锁定指令，对转发器进行加锁，使转发器处于仅能由该第一管理设备控制的第一锁定状态，此时转发器可以不接收或无视除该第一管理设备外的其他管理设备发送的指令或数据等，也可以回复通信失败或系统繁忙等信息，还可以仅开放查询接口，以供其他管理设备进行数据查询等，具体此处不作限定。锁定指令的具体方式可以参考下述图4所示实施例中步骤401的具体描述，本申请对此不限定，可以是其他的加锁方式。当该转发器处于第一锁定状态时，只能由该第一管理设备进行控制，其他管理设备不能对该转发器进行控制。因此，当第一管理设备对转发器进行控制时，例如，第一管理设备控制转发器对从该第一管理设备发送至用户设备的转发数据进行转发时。其他管理设备无法对该转发器进行控制，以避免其他管理设备修改转发器上的通信通道的配置数据，导致数据转发失败等。在多头管理的背景下，多个管理设备中的某个管理设备，如本实施例中的第一管理设备，例如某一SDN控制器，在转发器进行锁定后，其他管理设备不能够对该转发设备进行管理，从而使该第一管理设备在对转发器进行控制时不受其他管理设备的干扰，进而提高第一管理设备与转发器进行通信的效率以及可靠性。
302、第一管理设备进行差异比较；
当第一管理设备向转发器发送锁定，使转发器处于第一锁定状态后，第一管理设备确定自身的目标数据，以及采集转发器上与该目标数据对应的对应数据，并对该目标数据与对应数据进行差异比较，得到对比结果。第一管理设备可根据该对比结果以及预设的同步方式对目标数据与该对应数据进行同步，或由用户根据该第一管理设备通过用户界面呈现给用户的该对比结果确定对目标数据与该对应数据进行同步的同步方式。
其中，第一管理设备采集转发器上的对应数据的方式可以是通过yang模型采集，或也可以是通过树结构采集等，具体的实现方式参考下面图4至图8所示的实施例的具体描述。
303、第一管理设备与转发器进行数据同步；
在第一管理设备进行差异比较，得到对比结果后，第一管理设备与转发器之间进行数据同步，其中上面提到的预设的同步方式可以包括第一管理设备根据对比结果确定以目标数据为准对对应数据更新或以对应数据为准对目标数据更新等。当然，如上所述，在另外的实施方式中也可以包括由用户根据对比结果确定同步方式，例如由用户确定以目标数据为准对对应数据更新，或以对应数据为准对目标数据更新等。
因此，本申请实施例中，在第一管理设备对转发器进行加锁后，第一管理设备与转发器之间进行数据同步，此时可以不受其他管理设备的干扰，使第一管理设备与转发器之间的数据保持一致性，提高第一管理设备与转发器之间通信的效率以及可靠性。在数据同步完成后，该第一管理设备还可以向转发器下发配置数据，以使该控制器与该转发器正常通信。
在完成第一管理设备与转发器之间的数据同步后，第一管理设备可以与转发器进行正常通信，包括第一管理设备控制转发器对发送至用户设备的数据进行转发，或转发器对用户设发送的数据进行转发等。
此外，若在第一管理设备与转发器进行数据同步后，若第一管理设备确定第一管理设备上的数据与该转发器上的数据不一致，则第一管理设备可以以该第一管理设备上的数据对转发器上的数据进行更新。具体的可以参考下述图10所示的实施例的具体描述。
304、第一管理设备对转发器解锁；
在第一管理设备无需对转发器进行控制时，例如，该第一管理设备控制转发器向用户设备发送转发数据完成时，可以对转发器进行解锁。该第一管理设备对转发器解锁的具体方式可以是，该第一管理设备向转发器发送解锁指令，转发器在接收到解锁指令后，可以解除锁定状态。其中，解锁指令的具体方式可以参考下图4中所示实施例中步骤405的具体描述，本申请对此不限定，也可以是其他的解锁方式。当转发器解除锁定后，转发器可以接收该转发器范围内任何管理设备发送的信息或指令，以使其他管理设备根据需要对转发器进行加锁进而进行锁定控制，从而可以保障其他管理设备的正常通信，且通过该加锁解锁的切换，可以是转发器灵活地在多个管理设备间正常进行通信，提高转发器与其他管理设备进行通信的可靠性。可以理解，当其他管理设备都没有对该转发器进行锁定控制的情况下，该转发器处于接收多个管理设备控制的状态。各管理设备是否需要对转发器进行锁定是根据各管理设备于转发器进行数据交互的类型确定，若管理设备仅需要对该转发器上的数据进行查询，则该关联设备无需对该转发器进行查询，若该管理设备需要对该转发器进行控制或对管理设备上的数据与该转发器上的数据进行数据同步等，例如，控制转发器进行数据转发或控制转发器进行数据修改等，则该管理设备需要对该转发器进行加锁。
305、第二管理设备向转发器发送锁定指令；
在第一管理设备向转发器发送解锁指令后，转发器处于未锁定状态，此时，第二管理设备可以向转发器发送锁定指令，转发器可根据该第二管理设备发送的锁定指令，切换到仅能由该第二管理设备控制的第二锁定状态。此时，第二管理设备可以对该转发器进行控制，且不受其他管理设备的干扰。该第二管理设备也可以对该第二管理设备上的数据与该转发器上的数据进行差异比较，并基于该差异比较结果进行数据同步，使该第二管理设备上的数据与该转发器上的数据保持一致，当该第二管理设备为除控制器外的其他管理设备时，该第二管理设备也可以不进行差异比较，第二管理设备直接与该转发器进行通信等，具体此处不作限定。
306、第二管理设备向转发器发送解锁指令；
当第二管理设备无需再对转发器进行控制时，也需要向转发器发送解锁指令，以使转发器解除第二锁定状态。
307、第一管理设备向转发器发送锁定指令。
当转发器处于未锁定状态时，第一管理设备如需继续对该转发器进行控制，则第一管理设备需要重新向该转发器发送锁定指令，对转发器加锁后，才能继续与该转发器进行通信。例如，该第一管理设备需要重新通过该转发器向用户设备发送传输数据时，需要对该转发器进行控制，此时该第一管理设备可以向该转发器发送锁定指令，以使转发器切换到仅能由该第一管理设备控制的锁定状态。
应理解，在本申请实施例中，第一管理设备在对转发器进行控制时，对该转发器进行加锁，无需对转发器进行控制时，可以解除转发器的锁定状态，其中，加锁与解锁除了可以是本申请实施例中提供的具体加锁解锁步骤外，还可以是通过其他的方式进行加锁解锁。当转发器解除仅能由该第一管理设备控制的锁定状态后，该转发器可以由该第一管理设备重新进行加锁控制，也可以由第二管理设备进行加锁控制，具体此处不作限定，因此，步骤305至步骤307可以为可选步骤。
在本申请实施例中，当第一管理设备需要对转发器进行控制时，首先需要向转发器发送锁定指令，若转发器处于未锁定状态，则转发器可以切换到第一锁定状态，之后第一管理设备可以与转发器之间进行数据同步，保障第一管理设备与转发器之间数据的一致性。当第一管理设备无需对转发器进行控制时，可以向转发器发送解锁指令，解除转发器的第一锁定状态。此时，转发器可以正常接收其他管理设备的信息，可以由其他管理设备进行加锁以及控制。当转发器被加锁时，仅能由加锁的管理设备控制，当转发器未被加锁时，可以由其他设 备加锁后控制，因此转发器可以灵活地在各个管理设备之间进行切换，使转发器的多头管理场景可以正常通信以及工作。
前述对本申请实施例提供的数据处理的方法的流程进行了说明。下面对本申请实施中数据处理的方法进行更进一步地阐述，其中，以该第一管理设备为控制器为例进行说明，请参阅图4，本申请实施例汇总数据处理的方法的另一个实施例示意图，包括：
401、控制器向转发器发送锁定指令；
在控制器对转发器进行管理控制时，首先，控制器可以使用netconf协议向转发器发送锁定指令，在一个具体实施例中，该锁定指令中包括该控制器的身份信息以及加锁指示等，该控制器的身份信息可以是用户标识，即该控制器的标识，可以用于转发器识别加锁源，该加锁指示用于指示转发器切换到第一锁定状态。当该转发器处于第一锁定状态时，该转发器与该控制器之间建立有通信通道，转发器可以仅接收通过该通信通道发送的控制信息，即转发器仅可接收该控制器发送的控制信息，而不接收其他管理设备发送的控制信息。因此当转发器处于第一锁定状态时，该转发器只能由该控制器进行控制，可以避免当控制器对转发器进行控制时，转发器上的数据被其他管理设备修改，例如被其他控制器或管理服务器等修改，从而导致该控制器与转发器的通信错误或数据转发失败等情况。
402、转发器切换锁定状态；
在转发器接收到控制器发送的锁定指令时，该锁定指令中包括用户标识以及加锁指示，转发器可以根据该用户标识识别加锁源，若转发器当前处于未被锁定的状态，则转发器可以根据该加锁指示切换到仅能由该控制器控制的第一锁定状态。当该转发器处于仅能由该控制器控制的锁定状态时，转发器仅接收该控制器发送的控制信息，如果在这期间接收到其他管理设备，例如其他控制器或管理服务器，的控制信息时，转发器可以通过该用户标识确认该其他管理设备不是加锁源，从而可以丢弃该其他管理设备发送的控制信息或响应错误；此外，在转发器接收到控制器发送的锁定指令时，若转发器当前已处于锁定状态，即该转发器已被除该控制器外的其他管理设备控制，则该控制器当前无法对该转发器进行加锁，仅能在该转发器处于未锁定状态时该控制器才能对该转发器进行加锁。
403、控制器进行差异比较；
在控制器向转发器发送锁定指令，转发器切换到第一锁定状态时，转发器只能由控制器进行控制。控制器对控制器上的目标数据与转发器上的对应数据进行差异比较，得到差异比较的对比结果，该对比结果用于控制器确定目标数据与对应数据是否匹配。在一个具体的实施方式中，该控制器进行差异比较具体的步骤可以包括：
首先，控制器确定控制器上的目标数据，以及采集转发器上与目标数据对应的对应数据。其中，转发器可以提供数据查询接口，控制器可以使用该查询接口查询该转发器上与所述目标数据对应的对应数据。例如，控制器上包括与转发器进行通信的虚拟专用网络(Virtual Private Network，vpn)接口数据，则该转发器上也包括对应的vpn接口数据。此外，该目标数据与对应数据可以是其他配置数据或通信数据等。具体地，目标数据与对应数据的粒度可以是特性，例如，该特性可以是一个接口、模块等，该接口下可以包括多个子接口，或该模块下可以包括多个子模块等。目标数据与对应数据可以以yang模型呈现，也可以基于树的结构。例如，如图5所示，在对转发器上的对应数据进行采集时，目标数据与对应数据可以是接口管理(interface management，ifm)特性数据，例如，控制器与转发器上的接口数量、接口类型等，控制器以ifm特性为路径，对转发器上的ifm特性数据进行采集，ifm特性下的子特性为子节点，完成ifm特性的树结构采集。目标数据与对应数据可以是服务质量(quality of service，qos)特性数据，例如信道数据、地址数据等，如图6所示，对应数据在转发器的数据库中可以以树结构存储，则控制器以qos特性为路径进行对应数据的采集，每一个子节点都为qos特性下的子特性，采集该qos特性下的所有子节点，以完成qos特性的树结构的采集。此外，采集的起始节点除了可以是转发器数据库中的根节点，也可以是非根节点，例如，如图7所示，其中，A特性下的B特性与C特性分别为两个特性，可以以B特性或C特性为根节点，采集A特性下所有的子节点，以采集到完整的转发器的对应数据。因此，在实际应用中，控制器可以根据树结构进行对应数据的采集，能够采集到完整的对应数据，且效率高，准确性高。
然后，对控制器对自身的目标数据与转发器上与该目标数据对应的对应数据进行差异比较，若目标数据与对应数据的结构模型为树结构，则可以对目标数据的树结构与对应数据的树结构的子节点进行逐一遍历对比，在本申请实施例中，控制器可以对每个节点都进行对比，可以避免数据遗漏，使对比结果更准确。如图8所示，控制器对目标数据与对应数据，即控制器上的数据与转发器上的数据的树结构中的节点进行逐一广度遍历，可以得到差异比较的结果，即目标数据与对应数据的差异，例如，差异比较的结果可以是，如图9所示，目标数据的特性1的子特性多于对应数据的特性1的子特性，目标数据的特性2的子特性与对应数据的特性2的子特性一致，目标数据的特性3的子特性少于对应数据的特性3的子特，目标数据中的特性4的子特性与对应数据的特性4的子特性冲突等。然后由控制器确定目标数据与对应数据的同步方式，此外，若控制器包括显示界面，则可以在该显示界面中显示该对比结果，然后由用户选择对目标数据与对应数据的同步方式。
404、控制器与转发器进行数据同步；
在控制器进行差异比较，得到差异比较的对比结果后，若控制器通过该对比结果获知目标数据与对应数据不匹配，包括控制器与转发器上对应的数据不一致，或该控制器与该转发器上的数据不对应等，则控制器可以对目标数据与对应数据进行同步，使同步后的目标数据与对应数据匹配。在数据同步完成后，控制器还可以向转发器下发配置数据，以使该控制器与该转发器正常通信。进行数据同步的具体方式可以是，若以控制器上的数据为准对转发器上的数据进行更新，则控制器可以将更新信息发送至转发器，该更新信息可以是该控制器上的数据与该转发器上的数据有差异的部分，也可以是整个该控制器上的数据，具体此处不作限定。当转发器收到该更新信息后，可以将该更新信息保存至该转发器上，也可以是转发器根据该更新信息通过预置的方式对该转发器上的数据进行更新，具体此处不作限定。若以转发器上的数据为准对控制器上的数据进行更新，则控制器可以直接从转发器提供的数据查询接口中获取差异部分数据，然后将该差异部分数据保存至控制器，也可以是控制器获取转发器上所有与该控制器上的数据对应的数据，然后保存该所有与该控制器上的数据对应的数据等，具体此处不作限定。
一个具体的实施例中，上述同步过程可以参考图10，如图10所示，若目标数据中的特性1多于对应数据中的特性1，则控制器可以以目标数据中的特性1为准对对应数据中的特性1进行更新，使更新后的对应数据中的特性1与目标数据中的特性1保持一致。若目标数据中的特性2与对应数据中的特性2一致，则控制器可以不对目标数据与对应数据中的特性2进行更新。若目标数据中的特性3少于对应数据中的特性3，则控制器可以以对应数据中的特性3为准对目标数据中的特性3进行更新，使目标数据中的特性3与对应数据中的特性3保持一致。此外，若目标数据中的特性4与对应数据中的特性4冲突，则可以对目标数据或对应数据中的特性4进行标记，对目标数据中的特性4与对应数据中的特性4暂不处理，或以目标数据中的特性4对对应数据中的特性4进行更新，或者以对应数据中的特性4对目标数据中的特性4进行更新等。通过控制器根据预设的同步方式自动确定对目标数据与对应数据的同步方式，例如，针对不同特性的同步方式可以不同，从而可以提高对目标数据与对应数据进行同步的准确性，以及控制器的工作效率。在具体实施例中，该预设的同步方式可以包括，对于有冲突的数据，可以由控制器下发替换报文，以使转发器上的对应数据与控制器上的目标数据一致；对于控制器多出的数据，可以由控制器下发创建报文，由转发器添加该控制器多出的数据；对于转发器多出的数据，可以由控制器下发删除报文，以删除转发器上多出的数据；也可以是控制器直接下发替换报文，以目标数据为准更新对应数据等。
在另外的实施方式中，还可以是，在控制器上，或其他显示设备上显示差异比较的对比结果，由用户根据该对比结果选择同步方式，然后控制器可以接收用户的输入信息，然后由 该控制器或该转发器根据用户选择的同步方式对该目标数据与该对应数据进行同步。例如，可以在控制器或其他显示设备上显示如图9所示的界面，用户可以选择以对应数据中的特性1为准对目标数据中的特性1进行更新，或以目标数据中的特性3为准对对应数据中的特性3进行更新等。通过用户选择确定对目标数据与对应数据的同步方式，可以更灵活地确定目标数据与对应数据的更新方式，更贴近与实际需求。
此外，在控制器进行差异对比以及数据同步之后，若由于其他原因，例如，转发器重启，没有保存配置数据，转发器与控制器之间的网络故障，转发器自身繁忙等原因，导致转发器上的对应数据与控制器上的目标数据不一致，则可以以控制器上的目标数据为准对转发器上的对应数据进行更新，若由于控制器的原因导致控制器上的目标数据与转发器上的对应数据不一致时，也可以是以转发器上的数据为准对控制器上的目标数据进行更新。
405、转发器强制解锁；
在控制器与转发器进行数据同步后，控制器可以正常控制转发器进行通信，例如，控制器可以控制转发器向与该转发器连接的终端设备转发数据。当控制器无需再对转发器进行控制器时，可以向转发器发送解锁指令，使转发器解除锁定状态，解除锁定状态后转发器可以由其他管理设备进行控制。也可以是转发器进行强制解锁，例如，当控制器异常，包括宕机、断电或系统繁忙的原因，长时间未对转发器发送信息或回应，则转发器可以进行强制解锁，解除转发器的第一锁定状态，然后转发器可以与第二管理设备进行通信，接收第二管理设备的锁定指令等。其中，若由控制器向转发器发送解锁指令解锁，具体的解锁步骤可以是，控制器向转发器发送解锁指令，该解锁指令可以包括该控制器的身份信息以及解锁指示，该身份信息可以是用户标识，即该控制器的标识，转发器可以根据该用户标识与加锁源的用户标识进行对比，若该用户标识与加锁源的标识一致，则该转发器可以根据该解锁指示解除该第一锁定状态，若该用户标识与加锁源的标识不一致，则转发器可以不进行锁定状态解除。在本申请实施例中，当控制器在预置时间内未向转发器发送信息，或转发器所需数据不在该控制器的管理范围内时，转发器可直接解除锁定状态，之后该转发器可以与第二管理设备进行通信，避免因控制器长时间无回应而降低转发器的通信效率。转发器直接解除锁定状态后，若控制器正常工作，则控制器可以感知转发器解除由该控制器进行控制的锁定状态，若控制器需要向转发器发送数据，则该控制器需要重新对该转发器进行加锁，重新锁定后才能继续进行数据传输。例如，若控制器长时间对转发器无回应，而此时第二管理设备在等待对转发器进行控制，则可直接解除转发器的第一锁定状态，使第二管理设备可以向转发器发送锁定指令，降低第二管理设备的等待时长，以及提高第二管理设备与转发器的通信效率。而另一种情况为，转发器所需的数据不在该控制器的管理范围内，若该转发器所需的数据在第二管 理设备的管理范围内时，可以解除转发器的第一锁定状态，由第二管理设备对转发器进行加锁，然后转发器通过该第二管理设备获取该转发器所需的数据，提高该转发器的工作效率。
在控制器向转发器发送解锁指令后，转发器解除锁定状态，或转发器强制解锁后，若控制器需要再次控制转发器，则控制器需要重新向转发器发送锁定指令，使转发器重新处于锁定状态，并进行差异对比与数据同步，之后控制器才能对转发器进行控制。
406、第二管理设备向转发器发送锁定指令；
当转发器解除第一锁定状态时，也可以由除控制器外的第二管理设备向转发器发送锁定指令，具体的实施方式可以参考上述图4所示实施例中的步骤401，以使转发器处于被第二管理设备控制的锁定状态。该第二管理设备可以是包括命令行界面(command-line interface，CLI)的终端设备，也可以是其他网络管理设备，此外，该第二管理设备也可以是一个控制器。具体地，当该第二管理设备为一个包括CLI的终端设备，可以由用户或其他网管设备在CLI中输入控制指令，然后由该包括CLI的终端设备执行该指令，当转发器处于被该包括CLI的终端设备的锁定状态时，转发器仅能由该包括CLI的终端设备控制，包括仅能由该包括CLI的终端设备对该转发器上的数据进行修改，而除该包括CLI的终端设备外的管理设备无法对该转发器上的数据进行修改，以此避免转发器在与包括CLI的终端设备进行通信时，被除该包括CLI的终端设备外的其他管理设备修改数据，进而导致该转发器与该包括CLI的终端设备通信失败或数据转发失败等情况。
407、转发器切换锁定状态；
转发器在接收到第二管理设备发送的锁定指令后，可根据该锁定指令识别出加锁源为该第二管理设备，然后根据该锁定指令中的加锁指示切换至第二锁定状态，当该转发器处于第二锁定状态时，该转发器仅接收该第二管理设备的控制信息，例如，数据同步信息，配置数据等。
应理解，当该第二管理设备为除控制器外的管理设备时，该第二管理设备在向转发器发送锁定指令，以对转发器进行加锁后，该第二管理设备可以进行数据的差异比较与数据同步，也可以直接对该转发器进行控制，具体此处不作限定。
408、第二管理设备向转发器发送解锁指令。
当第二管理设备无需对转发器进行控制时，该第二管理设备可以向转发器发送解锁指令，以解除转发器仅能由该第二管理设备控制的第二锁定状态。
应理解，除了可以由第二管理设备向转发器发送解锁指令解除转发器的锁定状态外，也可以由转发器进行强制解锁，然后由其他管理设备通过另外的通道给转发器下发锁定指令以及配置，然后由其他管理设备控制转发器。例如，当用户发现控制器由于断电被关闭，或控 制器长时间无响应等情况，此时转发器仍然处于被控制器控制的锁定状态，那么，转发器可以进行强制解锁，解除控制器的控制，然后由其他管理设备对转发器进行加锁，由其他管理设备控制转发器。
409、转发器解除锁定状态；
转发器在接收到第二管理设备发送的解锁指令后，解除第二锁定状态，即转发器此时可以接收其他管理设备发送的锁定指令。
410、控制器向转发器发送锁定指令；
当转发器解除第二锁定状态后，若控制器需要对转发器进行控制，则控制器需要重新对该转发器发送锁定指令，以使该转发器切换为仅由该控制器控制的锁定状态，之后再进行数据同步以及数据传输等。
在本申请实施例中，在控制器对转发器进行管理控制时，首先，控制器向转发器发送锁定指令，对转发器进行加锁，使转发器处于仅能由控制器控制的锁定状态，防止在控制器与转发器进行通信时其他管理设备对转发器上的数据进行篡改，避免由于其他管理设备对转发器上的对应数据的修改导致的控制器上的目标数据与转发器上的对应数据不一致的问题，之后，控制器对目标数据与对应数据进行差异比较，并对目标数据与对应数据进行数据同步，使控制器上的目标数据与转发器上的转发数据保持一致，然后控制器与转发器可以进行通信，转发器由控制器控制。当控制器无需再对转发器进行控制时，可以向转发器发送解锁指令，以解除转发器的锁定状态，此时，可以由其他管理设备锁定转发器并进行控制与通信，可以避免该其他设备在与该转发器进行通信时数据被修改。
以一个具体的实施例为例，当前网络中包括一个控制器，一个转发器，以及一个网管设备，该控制器与网管设备都可以对转发器进行控制，当控制器需要对该转发器进行控制时，为避免网管设备对转发器进行控制，首先该控制器可以向该转发器发送锁定指令，以使转发器处于仅能由该控制器控制的锁定状态，此时网管设备无法控制转发器，无法对转发器上的配置数据进行修改。该控制器与该转发器之间建立有管理通道。当该转发器处于锁定状态后，控制器对目标数据，例如自身的目标配置数据，与转发器上对应数据，例如对应配置数据，进行差异比较可以是以数据中的特性为粒度，若该目标配置数据与该对应配置数据不一致，则控制器可以对该目标配置数据与对应配置数据进行更新，控制器可以以目标配置数据对该对应配置数据进行更新，也可以是以转发器上的对应配置数据对目标配置数据进行更新，以使该目标配置数据与该对应配置数据保持一致，避免因该目标配置数据与该对应配置数据不一致导致该控制器无法控制该转发器。若在控制器控制转发器时，控制器处于断电状态，转发器很长一段时间没有收到与控制器的通信数据，则此时可以转发器自动进行强制解锁，或 由转发器响应用户操作进行强制解锁等，即解除控制器对转发器的锁定状态，当控制器重新正常工作后，可以获取到转发器的状态。然后可以由网管设备通过另外的管理通道向该转发器发送锁定指令锁定转发器，以及下发网管设备的配置数据等。若控制器一直处于正常工作的状态，则控制器在无需对转发器进行控制器时，可以向该转发器发送解锁指令，以解除对转发器的锁定。之后可以由网管设备向转发器发送锁定指令，以使转发器处于由网管设备控制的锁定状态，之后网管设备对转发器进行控制以及正常通信等。
