具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。
网管服务器与网元之间进行交互的测试是网管测试中的重要组成部分。在一些情况下，模拟网元工具在模拟大量网元时，需要相同数量的网络协议(Internet Protocol，IP)地址。对于一个模拟工具而言，很难在公共网络中获取到这么多真实的IP地址，极大影响了网管服务器对于通信业务的压力测试。
对此，在本公开的实施例中，通过对网管侧和网元模拟侧进行改进，在网管侧引入网管代理单元，在网元模拟侧引入网元代理单元，网管代理单元和网元代理单元可以基于传输控制协议/网络协议(Transmission Control Protocol/Internet Protocol，TCP/IP)建立链路，并在该链路上实现网管侧和网元模拟侧的通信，使得可以使用任意IP地址和端口来模拟大量虚拟网元，而不再需要真实的IP地址和端口来标识虚拟网元。
图1为根据本公开实施例的网管侧的装置结构图，如图1所示，本公开提出的网管侧包括网管代理单元和其他单元，其中，网管代理单元用于通过与网元代理单元已建立的链路向所述网元代理单元发送测试消息，并通过所述链路接收网元代理单元返回的测试响应。在本公开的实施例中，其他单元包括如南向接口、配置管理单元南向接口支持多种形式的接口协议，提供对网元的管理功能；配置管理单元负责监控和管理网元的配置情况。
图2为根据本公开实施例的网元模拟侧的装置结构图，如图2所示，本公开提出的网元模拟侧包括网元代理单元和网元模拟应用单元。网元代理单元用于通过与网管代理单元已建立的链路接收网管代 理单元发送的测试消息，并触发网元模拟应用单元响应该测试消息，通过所述链路向网管代理单元发送测试响应。需要说明的是，在本公开的实施例中，在对网管服务器进行测试之前，网络管理员需要在网管侧服务器的输入界面针对环境变量这一网管参数输入网元代理单元的身份信息，以触发网管代理单元和网元代理单元建立基于TCP/IP的链路。链路建立之后，对网管服务器进行测试时，也需要网络管理员在网管侧服务器的输入界面针对环境变量这一网管参数输入虚拟网元的身份信息，以触发网管代理单元根据当前需要触发测试。所述网元代理单元的身份信息具体可以是网元代理单元的IP地址和端口，虚拟网元的身份信息具体可以是虚拟网元的IP地址和端口。
通过网管代理单元和网元代理单元已建立的链路，网管侧的环境变量中输入了虚拟网元的身份信息后，具体地，图3为根据本公开实施例的网管侧与网元模拟侧进行交互的示意图，如图3所示，网管代理单元会发送测试消息给网元代理单元，即图3中所示的A过程；网元代理单元在收到测试消息后，触发网元模拟应用单元响应测试消息，即图3中所示的B过程；当网元模拟应用单元响应测试消息后，会将测试响应发送给网元代理单元，即图3中所示的C过程；最后，网元代理单元将测试响应转发给网管代理单元，即图3中所示的D过程。同时，网元模拟应用单元在监测到虚拟网元的配置数据发生变化时，也会主动上报数据配置变更报文给网元代理单元，并通过网元代理单元将配置数据变更报文转发给网管代理单元，即图3中所示的C过程和D过程。
以上网管侧和网元模拟侧在已建立的链路上进行交互的过程中，网元代理单元可接收网管代理单元发送的对多个不同虚拟网元的测试消息，并在网元模拟应用单元中实现不同虚拟网元的测试应用，而该多个虚拟网元和网管代理单元的交互均是在已经建立好的链路上执行的，网管代理单元并不需要和每个虚拟网元都建立基于TCP/IP的链路。因此，在本公开的实施例中，虚拟网元的身份信息只是用来对应一个虚拟网元，从而对该虚拟网元予以标识，各虚拟网元与网管 代理单元之间的交互均可以通过已建立好的链路进行，虚拟网元的身份信息可以任意配置。
基于以上，本公开实施例的基本思想是：在网管代理单元和网元代理单元已建立好链路后，基于该链路来实现网管侧和网元模拟侧的交互，以此来实现大量虚拟网元与网管侧的交互。
在本申请实施例中，网管侧对虚拟网元的管理涉及网管代理单元、网元代理单元、网元模拟应用单元，还可涉及到网管侧的南向接口、网管配置单元。
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。
本公开实施例提供一种网元管理方法，应用于网管代理单元中，图4为根据本公开实施例的一种网元管理方法的流程示意图，如图4所示，在本公开的实施例中，应用于网管代理单元的网元管理方法可以包括以下步骤：步骤S401-S402。
在步骤S401，接收到输入的虚拟网元的身份信息，通过与网元代理单元已建立的链路向网元代理单元发送测试消息，测试消息中携带有虚拟网元的身份信息。
在本公开的实施例中，当网络管理员在网管侧服务器的输入界面针对环境变量这一网管参数输入虚拟网元的身份信息时，会触发网管代理单元通过与网元代理单元已建立的链路向网元代理单元发送测试消息，测试消息中携带有虚拟网元的身份信息。
需要说明的是，在本公开的实施例中，网管代理单元向网元代理单元发送测试消息是建立在网管代理单元和网元代理单元已建立好的链路基础上实现的，虚拟网元的身份信息只是用来标识虚拟网元，并不用于真实的链路建立。在网络管理员需要对网管服务器的压力进行测试时，需要事先在网管侧配置虚拟网元的身份信息，以此标识网元模拟侧的虚拟网元，即承载于网元模拟应用单元的虚拟网元。
在本公开的实施例中，网管代理单元和网元代理单元之间的链路只需建立一次即可。具体地，当接收到输入的网元代理单元的身份信息，网管代理单元向网元代理单元的身份信息标识的网元代理单元 发送建链请求，网管代理单元与网元代理单元进行三次握手完成链路建立过程，即网管代理单元和网元代理单元可基于TCP/IP建立链路。当网管代理单元在一定时间内没有收到网元代理单元发送的心跳报文后，说明网元代理单元和网管代理单元之间的链路已经断开，此时，需要重新执行链路建立过程。
在确保链路建立好的基础上，网管代理单元就可和网元模拟侧基于现有协议来交互测试消息了。现有协议可以是网络配置协议(Network Configuration Protocol，NETCONF)或简单网络管理协议(Simple Network Management Protocol，SNMP)，在本公开的实施例中，以NETCONF为例进行说明，NETCONF中包括能力协商消息和配置数据查询消息。
示例性的，网管代理单元需要进行能力协商的测试时，网管代理单元需要和虚拟网元建立会话，通过会话的建立来交互双方的能力，此时，测试消息为能力协商消息，网管代理单元和网元模拟侧进行能力协商之后，即完成了网管侧和虚拟网元之间会话的建立。当网管代理单元需要对查询配置数据进行测试时，此时，测试消息为配置数据查询消息，网管代理单元在收到数据配置响应后，会将数据配置响应转发给网管侧的网管配置单元，以便网管配置单元对数据配置进行后续操作，如对配置数据进行修改、删除等操作。
在步骤S402，通过链路接收网元代理单元转发的网元模拟应用单元响应测试消息的测试响应，网元模拟应用单元用于承载虚拟网元的身份信息标识的虚拟网元。
在本公开的实施例中，网管代理单元基于和网元代理单元已建立好的链路接收网元代理单元转发的网元模拟应用单元响应测试消息的测试响应。
需要说明的是，在本公开的实施例中，网元模拟应用单元用于承载虚拟网元的身份信息标识的虚拟网元，网管代理单元对虚拟网元的控制，是通过发送相应的测试消息来实现的，而发送的测试消息，均通过网元模拟应用单元来实现反馈。
当网管代理单元需要进行能力协商的测试时，会发送能力协商 消息给网元代理单元，网管代理单元在发送能力协商消息后，会接收到网元模拟侧的反馈，具体地：网管代理单元通过链路接收网元代理单元转发的网元模拟应用单元响应能力协商消息的能力协商响应，能力协商响应携带有虚拟网元的能力信息，虚拟网元的能力信息为网元模拟应用单元收到能力协商消息后通过能力协商所确定的。
当网管代理单元需要对查询配置数据进行测试时，会发送配置数据查询消息给网元代理单元，网管代理单元在发送配置数据查询消息后，会接收到网元模拟侧的反馈，具体地：网管代理单元通过链路接收网元代理单元转发的网元模拟应用单元响应所述配置数据查询消息的数据配置响应，数据配置响应携带有虚拟网元的配置数据，配置数据为网元模拟应用单元收到配置数据查询消息后查询得到的。
在本公开的实施例中，当网络管理员设置好虚拟网元的配置数据之后，可能还会重新设置虚拟网元的配置数据。当网络管理员重新设置了原有配置数据后，网元模拟应用单元会监测到虚拟网元的配置数据发生变更，此时，网元模拟应用单元会主动上报携带有更改后的、对应于虚拟网元的配置数据的数据配置变更报文给网元代理单元，网管代理单元会同步接收到网元代理单元转发的数据配置变更报文，并将该报文转发给网管配置单元，以便网管配置单元对存储的配置数据做调整。
可以理解的是，在本公开的实施例中，当网管侧配置虚拟网元的身份信息时，会触发网管代理单元能根据与网元代理单元已建立的链路和虚拟网元进行交互，通过建立的链路传输测试消息，而不需要与每个虚拟网元分别去建立链路，从而实现了基于一个真实的身份信息、即网元代理单元的身份信息来与网元模拟侧进行信息交互，虚拟网元的身份信息可在网管侧随意配置。
本公开实施例提供一种网元管理方法，应用于网元代理单元中，图5为根据本公开实施例的一种网元管理方法的另一流程示意图，如图5所示，在本公开的实施例中，应用于网元代理单元的网元管理方法可以包括以下步骤：步骤S501-S504。
在步骤S501，通过与网管代理单元已建立的链路接收网管代理 单元发送的测试消息，测试消息中携带有虚拟网元的身份信息。
在本公开的实施例中，网元代理单元与网管代理单元基于已建立的链路接收网管代理单元发送的测试消息，测试消息中携带有虚拟网元的身份信息。
需要说明的是，在本公开的实施例中，网元代理单元接收网管代理单元发送的测试消息是建立在网管代理单元和网元代理单元已建立好的链路基础上实现的，虚拟网元的身份信息只是用来标识虚拟网元，并不用于真实的链路建立。在网络管理员需要对网管服务器的压力进行测试时，需要事先在网管侧配置虚拟网元的身份信息。
在本公开的实施例中，网管代理单元和网元代理单元之间的链路只需建立一次即可。具体地，网元代理单元接收网管代理单元发送的建链请求后，网元代理单元与网管代理单元进行三次握手完成网络链路建立过程，即网元代理单元和网管代理单元基于TCP/IP建立链路。当网元代理单元在一定时间内没有收到网管代理单元发送的心跳报文后，说明网管代理单元和网元代理单元之间的链路已经断开，此时，需要重新执行链路建立过程。
在步骤S502，触发网元模拟应用单元响应测试消息。
在本公开的实施例中，在链路建立好后，网元代理单元在收到网管代理单元发送的测试消息后就可触发网元模拟应用单元响应测试消息了。
具体地，网元代理单元解析测试消息，获取虚拟网元的身份信息，并将虚拟网元的身份信息映射成唯一标识，该唯一标识用于在网元模拟应用单元中标识虚拟网元，当映射完成后，网元代理单元将唯一标识和测试消息中的测试内容发送给网元模拟应用单元，由网元模拟应用单元来响应测试内容。
在确保链路建立好的基础上，网元模拟侧就可和网管代理单元基于现有协议来交互测试消息了。现有协议，可以是NETCONF或SNMP。在本公开的实施例中，以NETCONF为例进行说明，NETCONF中包括能力协商消息和配置数据查询消息。
当网管代理单元需要进行能力协商的测试时，网元代理单元会 接收网管代理单元发送的能力协商消息；当网管代理单元需要对查询配置数据进行测试时，网元代理单元会接收网管代理单元发送的配置数据查询消息。具体地：当网元模拟侧的网元代理单元接收到测试消息后，会解析出测试消息中的用于标识虚拟网元的身份信息，并将虚拟网元的身份信息映射成在网元模拟应用单元中标识虚拟网元的唯一标识，随后网元代理单元将唯一标识和测试内容发送给网元模拟应用单元。
在步骤S503，接收网元模拟应用单元响应测试消息的测试响应，测试响应为承载虚拟网元的身份信息标识的虚拟网元的网元模拟应用单元发出的。
在本公开的实施例中，网元代理单元在将唯一标识和测试内容发送给网元模拟应用单元后，会收到网元模拟应用单元响应测试消息的测试响应。需要说明的是，在本公开的实施例中，网元模拟应用单元用于承载虚拟网元的身份信息标识的虚拟网元，即虚拟网元的功能依托网元模拟应用单元来模拟实现。
具体地，当测试内容表征为进行能力协商的测试时，网元代理单元接收网元模拟应用单元响应能力协商消息的能力协商响应，能力协商响应携带有虚拟网元的能力信息，虚拟网元的能力信息为网元模拟应用单元收到能力协商消息后通过能力协商所确定的。
当测试内容表征为进行配置数据查询的测试时，网元代理单元接收网元模拟应用单元响应配置数据查询消息的数据配置响应，数据配置响应携带有虚拟网元的配置数据，配置数据为网元模拟应用单元收到配置数据查询消息后查询得到的。
在步骤S504，通过链路转发测试响应给网管代理单元。
在本公开的实施例中，网元代理单元收到网元模拟应用单元的测试响应后，会通过链路转发测试响应给网管代理单元。
示例性的，当测试消息为能力协商消息时，网管代理单元和网元模拟侧进行能力协商之后，即完成了网管代理单元和虚拟网元的会话建立；当测试消息为配置数据查询消息时，网元代理单元在收到网元模拟应用单元反馈的数据配置响应后，会通过网管代理单元和网元 代理单元之间的链路将数据配置响应转发给网管代理单元，随后网管代理单元再将数据配置响应转发给网管侧的网管配置单元，以便网管配置单元对数据配置进行后续操作，如修改、删除等操作。
在本公开的实施例中，当网络管理员设置好虚拟网元的配置数据之后，可能还会重新设置虚拟网元的配置数据。当网络管理员重新设置了原有配置数据后，网元模拟应用单元会监测到虚拟网元的配置数据发生变更，此时，网元代理单元会接收网元模拟应用单元主动上报的数据配置变更报文，数据配置变更报文携带有更改后的、对应于虚拟网元的配置数据，其设置为网管配置单元根据配置数据调整存储的配置数据。
可以理解的是，在本公开的实施例中，网元代理单元用于和网管代理单元建立链路，并在已建立的链路上来进行网管代理单元和虚拟网元的测试消息交互，而不需要每个虚拟网元分别与网管代理单元去建立链路，从而实现了基于一个真实的身份信息，即网元代理单元的身份信息来与网管侧进行测试消息交互，虚拟网元的身份信息可随意配置。
本公开实施例提供了一种网元管理方法，应用于网管代理单元、网元代理单元中。当网管代理单元和网元代理单元间的链路建立好之后，网管代理单元通过与网元代理单元已建立的链路向网元代理单元发送测试消息，所述测试消息中携带有虚拟网元的身份信息；网元代理单元基于收到的测试消息，触发网元模拟应用单元响应测试消息；随后，网元代理单元接收网元模拟应用单元的测试响应，并将测试响应基于链路转发给网管侧的网管代理单元。
图6为根据本公开实施例的一种网元管理方法的交互流程图，如图6所示，在本公开的实施例中，网管代理单元、网元代理单元的交互过程可以包括以下步骤：步骤S601-S604。
在步骤S601，网管代理单元通过与网元代理单元已建立的链路向网元代理单元发送测试消息。
在本公开的实施例中，当网络管理员在网管侧服务器的输入界面针对环境变量这一网管参数输入了虚拟网元的身份信息时，在链路 建立好的基础上，网管代理单元就可通过该链路给网元代理单元发送测试消息了。需要说明的是，该测试消息中携带有虚拟网元的身份信息。
在步骤S602，网元代理单元通过与网管代理单元已建立的链路接收到网管代理单元发送的测试消息，触发网元模拟应用单元响应测试消息。
具体地，网元代理单元解析接收到的测试消息，获取虚拟网元的身份信息，并将虚拟网元的身份信息映射成唯一标识，该唯一标识用于在网元模拟应用单元中标识虚拟网元，当映射完成后，网元代理单元将唯一标识和测试消息中的测试内容发送给网元模拟应用单元，由网元模拟应用单元来响应测试内容。
在步骤S603，网元代理单元接收网元模拟应用单元响应测试消息的测试响应。
在本公开的实施例中，网元代理单元在发送测试内容和唯一标识给网元模拟应用单元后，会接收网元模拟应用单元反馈测试消息的测试响应。
在步骤S604，网元代理单元通过与网管代理单元已建立的链路将测试响应转发给网管侧的网管代理单元。
在本公开的实施例中，网元代理单元在接收到网元模拟应用单元的测试响应后，会通过已和网管代理单元建立的链路上将测试响应转发给网管代理单元，以此实现对网管服务器的测试。
图7为根据本公开实施例的一种网元管理方法的另一交互流程图，如图7所示，示例性的，在本公开的实施例中，网络管理员通过在网管侧服务器的输入界面针对环境变量这一网管参数输入网元代理单元的身份信息，触发网管代理单元和网元代理单元建立基于TCP/IP的链路。链路建立之后，网络管理员针对环境变量这一网管参数输入虚拟网元的身份信息，触发网管代理单元来根据当前需要触发测试。以NETCONF的能力协商消息为例进行说明，网管侧是网络配置的客户端Netconf Client，网元模拟侧是网络配置的服务端Netconf Server。网管代理单元、网元代理单元以及网元模拟应用单 元建立连接的交互过程可以包括如下步骤：步骤S701-S706。
在步骤S701，网管代理单元通过与网元代理单元已建立好的链路发送含有虚拟网元的身份信息的能力协商消息给网元代理单元。
示例性的，在本公开的实施例中，Netconf Client是基于opendaylight的Netconf项目实现的，在其中增加了一种代理方式，即网管代理单元，可将所有Netconf Client中原来由南向接口发出的测试消息，都通过网管代理单元来发送，且网管代理单元将测试消息发送到网元代理单元。
具体地，在本公开的实施例中，网元代理单元是一个基于Netty的Socket代理服务器。若网管侧的环境变量中配置有网元代理单元的身份信息，如Socket代理的IP地址和端口，当网管侧的环境变量中配置了虚拟网元的身份信息后，则原来由南向接口发出的能力协商消息，会通过网管代理单元发送给Socket代理所在的IP地址和端口，并在能力协商消息中附带虚拟网元的身份信息，如虚拟网元的IP地址和端口；若没有配置Socket代理的IP地址和端口，则会由南向接口直接向真实网元发送能力协商消息。
在步骤S702，网元代理单元接收到能力协商消息后，解析能力协商消息，获取虚拟网元的身份标识信信息，并将虚拟网元的身份信息映射成唯一标识。
示例性的，在本公开的实施例中，网元代理单元在收到能力协商消息后，会解析能力协商消息来获取虚拟网元的IP地址和端口，并将虚拟网元的IP地址和端口映射成唯一标识，该唯一标识用来在网元模拟应用单元中标识虚拟网元。
在步骤S703，网元代理单元将能力协商消息中的能力协商内容和唯一标识给网元模拟应用单元。
需要说明的是，在NETCONF中，能力协商的过程是通过交换hello消息来实现的。
在步骤S704，网元模拟应用单元根据NETCONF构造能力协商内容的能力协商响应。
在本公开的实施例中，网元模拟应用单元在收到网元代理单元 发送的能力协商内容和唯一标识后，会响应能力协商内容。具体地，网元模拟应用单元会构造一个包含唯一标识所表征的虚拟网元的能力集列表<hello>元素。
在步骤S705，网元模拟应用单元将能力协商响应发送给网元代理单元。
具体地，网元模拟应用单元将能力集列表<hello>元素发送给网元代理单元。
在步骤S706，网元代理单元将能力协商响应通过事先建立的链路转发给网管代理单元。
具体地，网元代理单元将能力集列表<hello>元素通过已建立的链路转发给网代理单元。
示例性的，在本公开的实施例中，会由网元代理单元，即Socket代理服务器和网管代理单元基于已建立的链路来交互NETCONF规定的能力协商消息，并转发能力协商响应给网管代理单元来通知虚拟网元的能力。
在本公开的实施例中，通过上述S701-S706，基于网管代理单元和网元代理单元已建立的链路，来完成网管代理单元和虚拟网元的能力协商。网管代理单元和不同虚拟网元本质上并不需要建立相应数量的链路，网管代理单元无论和多少虚拟网元通信，只需要在网管代理单元和网元代理单元的链路上通信即可。示例性的，如网管代理单元和网元模拟侧的网元代理单元及网元模拟应用单元基于链路建立相应数量的线程，来实现大量虚拟网元的模拟，其中的一个线程，就代表了一个虚拟网元。在网元模拟侧，虚拟网元的身份信息只是用来标识虚拟网元，并不用于真实的链路建立，因此，虚拟网元的身份信息可以随意配置。
图8为根据本公开实施例的一种虚拟网元创建的示意图，如图8所示，在网络管理员在网管侧服务器的输入界面针对环境变量这一网管参数输入网元代理单元的身份信息后，网管侧和网元模拟侧就可通过网管代理单元和网元代理单元来建立链路了，在链路建立的基础上，在需要对网管服务器进行测试时，通过网络管理员在环境变量中输入 虚拟网元的身份信息，网管代理单元和网元代理单元即可通过网元代理单元的身份信息，如NETCONF规定的830端口来构造网元1至网元N，以此来模拟大量网元，并基于网元模拟应用单元来实现对虚拟网元的测试模拟。网元1至网元N和网管侧的交互，均是在同一个链路上执行，网元1至网元N的身份信息，只是用来对应一个虚拟网元，从而对该虚拟网元予以标识。
图9为根据本公开实施例的一种网元管理方法的另一交互流程图，与图7的实施例中相同的原理，如图9所示，示例性的，在本公开的实施例中，以NETCONF中的配置数据查询消息为例进行说明，网管配置单元、网管代理单元、网元代理单元以及网元模拟应用单元建立连接的交互过程可以包括如下步骤：步骤S901-S908。
在步骤S901，网管代理单元通过与网元代理单元已建立好的链路发送携带有虚拟网元身份信息的配置数据查询消息给网元代理单元。
在本公开的实施例中，网元代理单元是一个基于Netty的Socket代理服务器。若网管侧的环境变量中配置有网元代理单元的身份信息，如Socket代理的IP地址和端口，当网管侧的环境变量中配置了虚拟网元的身份信息后，则原来由南向接口发出的配置数据查询消息，会通过网管代理单元发送给Socket代理所在的IP地址和端口，并在配置数据查询消息中附带虚拟网元的身份信息，如虚拟网元的IP地址和端口；若没有配置Socket代理的IP地址和端口，则会由南向接口直接向真实网元发送配置数据查询消息。
示例性的，在NETCONF中，配置数据查询消息是通过网管代理单元发送get-config消息给网元代理单元的。
在步骤S902，网元代理单元接收到配置数据查询消息后，解析配置数据查询消息，获取虚拟网元的身份信息，并将虚拟网元的身份信息映射成唯一标识。
示例性的，在本公开的实施例中，网元代理单元在收到配置数据查询消息后，会解析配置数据查询消息来获取虚拟网元的IP地址和端口，并将虚拟网元的IP地址和端口映射成唯一标识，该唯一标 识用来在网元模拟应用单元中标识虚拟网元。
在步骤S903，网元代理单元将配置数据查询消息中的配置数据查询内容和唯一标识给网元模拟应用单元。
在步骤S904，网元模拟应用单元根据NETCONF构造配置数据查询内容的数据配置响应。
在本公开的实施例中，网元模拟应用单元在收到网元代理单元发送的配置数据查询内容和唯一标识后，会查询虚拟网元的身份信息所标识的虚拟网元的数据配置。
在步骤S905，网元模拟应用单元将数据配置响应发送给网元代理单元。
在本公开的实施例中，网元模拟应用单元将虚拟网元的身份信息所标识的虚拟网元的数据配置发送给网元代理单元。
在步骤S906，网元代理单元将数据配置响应通过已建立好的链路转发给网管代理单元。
在本公开的实施例中，网元代理单元将虚拟网元的身份信息所标识的虚拟网元的数据配置通过已建立好的链路转发给网管代理单元。
在步骤S907，网管代理单元将数据配置响应转发给网管中的网管配置单元。
在步骤S908，网管配置单元处理数据配置响应。
示例性地，如网管配置单元对虚拟网元的配置数据进行修改。
在图9所示的网管代理单元和网元代理单元之间处理配置数据查询消息的基础上，图10为根据本公开实施例的一种网元模拟应用单元主动上报数据配置变更报文的交互流程图，如图10所示，示例性的，在本公开的实施例中，网管侧和网元模拟侧的交互过程还可以包括以下步骤：步骤S1001-S1005。
在步骤S1001，网元模拟应用单元构造数据配置变更报文。
具体地，在本公开的实施例中，当网络管理员设置好虚拟网元的配置数据之后，可能还会重新设置虚拟网元的配置数据。当网络管理员重新设置了原有配置数据后，网元模拟应用单元会监测到虚拟网 元的配置数据发生变更，此时，网元模拟应用单元会构造数据配置变更报文。
