针对相关技术中存在的上述问题，下面结合具体的可选实施例进行说明，在下述可选实施例中结合了上述可选实施例及其可选实施方式。
为实现上述发明目的，本发明可选实施例采用以下技术方案：
本发明可选实施例中的隧道的调整装置包括以下3个模块：拓扑变迁参数输入模块、隧道影响分析和重计算模块、隧道自动配置下发模块。
本发明可选实施例中隧道的调整方法，其步骤包括：
1、网络维护操作员指定变迁前的网络拓扑和变迁后的网络拓扑。
2、系统获取变迁拓扑后，进行隧道的影响分析和重计算，给出相应的操作方案后入库。
3、调用隧道自动配置模块，按照引擎的调度，从协议池捞取对应的协议，改配隧道，最后下发创建的设备。
下面将结合附图对本发明可选实施例自动单机分布式部署方法进行说明。
图6是相关技术中网络变迁下隧道自适应调整方法示意图。如图6中的步骤S602至步骤S606所示，现状是从人工检查网络变迁需要变动的拓扑，人工分析拓扑上承载的隧道，分析隧道的变迁后可用的路由后改配隧道。最后逐一修改隧道经过的每一个设备的过程。图7是根据本发明实施例的隧道的调整示意图，如图7的步骤S702至步骤S706所示，用户输入变迁前后的网络拓扑后，系统自动分析重计算，再通过批量自动配置到每一个设备的过程。
图8是根据本发明实施例的隧道的调整框架图，如图8所示，该框架图中包括3个功能模块，拓扑变迁参数输入模块82，隧道解析分析和重计算模块84，隧道自动配置下发模块86。
网络变迁下隧道自适应调整系统启动后，用户输入隧道迁移的场景，比如，扩环加链、接入环拆分或者汇聚环NNI端口网元间变迁。用户输入变迁前隧道和变迁后隧道。系统调用隧道影响分析和重计算的模块算法，系统分析变迁前隧道的配置情况，包括路由和保护等信息。然后计算变迁后的路由中可承载隧道的最短空闲路由。最后给出隧道改配需要涉及到的每个网元的隧道迁移单。用户根据实际情况，选择需要迁移的隧道进行改配。涉及的隧道改配的网元隧道迁移单数据入库。系统从协议池中，获取隧道改配需要的协议，包括OAM，QOS，TNP等下发设备。数据下给设备失败，返回数据库入库，提示用户下发失败，数据下发给设备成功后，结束隧道迁移流程。至此，网络变迁下隧道自适应调整系统和方法流程结束。
图9是根据本发明实施例的隧道的调整流程图(一)。如图9所示，该流程包括如下步骤：
步骤S902，选择隧道迁移的场景；
步骤S904，输入变迁前序列和变迁后序列；
步骤S906，系统调用隧道影响分析和重计算的模块算法，系统分析变迁前隧道的配置情况，包括路由和保护等信息，然后计算变迁后的路由中可承载隧道的最短空闲路由；
步骤S908，输出隧道改配需要涉及到的每个网元的隧道迁移单；
步骤S910，用户根据实际情况，选择需要迁移的隧道进行改配；
步骤S912，涉及的隧道改配的网元隧道迁移单数据入库；
步骤S914，从数据路获取操作方案；
步骤S916，从协议池捞取协议删除、修改、创建隧道；
步骤S918，系统从协议池中，获取隧道改配需要的协议，包括OAM，QOS，TNP等下发设备。
步骤S920，判断数据下发是否成功，如果数据下发给设备成功后，结束隧道迁移流程，如果否，返回步骤S912，提示用户下发失败。
至此，网络变迁下隧道自适应调整流程结束。
以汇聚环NNI端口网元间变迁场景为例，经过BC网元间有4条隧道。将BC设备之间的网络拓扑调整为BCD之间的网络拓扑，系统自动分析给出后隧道经过的路由和承载的拓扑为BCD，并给出可以批量迁移4条隧道。用户选择2条下发给设备。启动网络变迁下隧道自适应调整系统，用户选取隧道迁移的场景为汇聚环NNI端口网元间变迁，系统在界面展现这种隧道迁移场景的配置介绍，点击下一步，用户选择在这种场景下变迁前BC之间的网络拓扑，变迁后BCD之间的网络拓扑，点击下一步，系统自动分析用户输入的的变迁前网络拓扑上承载的经过的隧道，包括中间经过BC网络拓扑的隧道和以BC为上下点的终结隧道以及承载的 保护隧道，再重新查找变迁后网络拓扑上，可承载隧道的网络路由，并计算出最短的路径，最后输入隧道迁移单，在界面显示出了经过在BC之间的4条受影响的隧道的名称，和隧道的起始点的端口。用户根据自己的需要选择需要迁移的2条隧道。点击下一步，用户选择的这2条改配隧道和对应的隧道迁移单数据入库。系统从协议池中获取隧道迁移单中改配隧道需要的OAM和TNP协议，按照迁移单的顺序下发给BCD设备。当预计算失败，返回失败信息给数据库，并在客户端显示，隧道迁移失败。如果预计算成功，调用适配器，找到对应的BCD设备类型，再通过设备类型找到对应的适配器容器，再找到对应的设备，下发业务。下发设备后，设备返回信息给数据库，提示隧道迁移完成。
图10是根据本发明实施例的隧道调整流程图(二)，如图10所示，该流程包括如下步骤：
步骤S1002，用户选取隧道迁移场景为汇聚环NNI端口网元间变迁；
步骤S1004，用户选取变迁前序列(B和D设备间链路)和变迁后序列(B和C和D之间的链路)；
步骤S1006，系统自动给出隧道迁移单(4条可以迁移的隧道)；
步骤S1008，用户选择需要变迁的隧道(2条)；
步骤S1010，用户选择下发迁移操作；
步骤S1012，数据入数据库DB；
步骤S1014，系统给出需要对3个网元进行创建、删除、修改隧道操作；
步骤S1016，从协议池捞取OAM，QOS等配置隧道所需协议；
步骤S1018，给出对3个网元命令下发的队列；
步骤S1020，判断预计算是否成功，如果是，执行步骤S1022，如果否，执行步骤S1012；
步骤S1022，下发设备。
综上所述，通过本发明，采用在网络拓扑结构发生变化时，获取网络拓扑结构发生变化前的第一类隧道和网络拓扑结构发生变化后的第二类隧道；依据该第二类隧道相对于该第一类隧道的变化信息确定需要迁移的多个隧道；将该多个隧道的迁移信息下发至该述多个隧道所经过的各个设备，解决了相关技术中单纯依靠单条的隧道修改功能一一调整，时间和人力消耗都无法满足工程网络改造的进度要求的问题，进而达到了大幅缩短人工计算隧道路由和隧道配置的时间，提升网络维护的效率，可以提供批量改配和批量下发的自动化效果。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个 集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
