在地震、火灾等重大安全事件中，微波设备凭借其本身低时延、高弹性及高可靠性发挥重要作用，其部署的灵活性和建设成本低也使其成为5G技术落地的关键推动者。

本申请实施例提供了一种微波网络根节点查询方法，本实施方式的核心在于包括：识别微波网络的拓扑结构，拓扑结构至少包括微波网络的链路端口信息；收集微波网络中连接网管设备的出端口信息；根据出端口信息在微波网络的拓扑结构中筛选出微波网络的根节点， 其中，根节点的出端口信息未包含在微波网络的链路端口信息中。如此，实现了微波网络根节点自动查询，无需人工介入，根节点查询的及时性较高，所查询到的根节点的可靠性也较高。
下面对本实施方式的微波网络根节点查询方法的实现细节进行具体的说明，以下内容仅为方便理解提供的实现细节，并非实施本方案的必须。
本实施方式中的微波网络根节点查询方法的流程示意图如图1所示：
步骤S11：识别微波网络的拓扑结构，拓扑结构至少包括微波网络的链路端口信息。
具体地说，当用户需要确定某个网元所在微波网络的根节点时，可在显示界面选中该目标网元，以此作为触发微波网络根节点查询方法的触发条件。本实施例中可点选任意网元，采用网管设备与微波网元交互并计算的方式，自动识别其所在的网络拓扑。
在识别微波网络的拓扑结构过程中，依据目标网元所在链路的首/末网元信息计算出所有连通网元并对所有连通网元逐一进行此操作，并存储相关信息，存储的相关信息至少包括微波网络的链路端口信息。
在一实施方式中，拓扑结构中的信息包括网元信息，网元信息包括：网元ID，网元ID作为网管上网元的唯一标识；网元IP，网元IP用于网管与网元通信；网元显示名称，网元显示名称用于网管显示，便于人机交互；网元通断状态，网元通断状态用于网管与网元通信。
拓扑结构中的信息还包括链路信息，链路信息包括：链路ID，链路ID作为网管上链路的唯一标识；链路显示名称，链路显示名称用于网管显示，便于人机交互；链路源网元ID和链路目的网元ID，链路源网元ID和链路目的网元ID用于网管链路计算；链路端口信息，链路端口信息用于出端口计算，链路端口信息包括链路源端口信息和链路目的端口信息。链路端口信息是指微波网络中两两网元之间的所形成的链路的端口信息，因此，微波网络的链路端口信息中不包括网元直接与网管设备连接的出端口信息。
步骤S12：收集微波网络中连接网管设备的出端口信息。
具体地说，由网管设备作为控制器分析网元基本信息，识别网元版本等关键信息，通过南向接口，向网元获取能够连通网管设备的出端口信息。南向接口输入输出参数可规定如下：
Figure PCTCN2023071050-appb-000001
在一些例子中，收集微波网络中连接网管设备的出端口信息包括：向微波网络中的网元发送端口查询请求，端口查询请求包含网管设备的网关标识，所述端口查询请求以供网元根据网关标识确定连接网管设备的出端口信息；接收微波网络中的网元发送的连接网管设备的出端口信息。
具体地说，网元中存储有路由表，该路由表中存储有该网元的各个出端口信息、以及对应每个出端口信息的连接设备标识。网元在获取网管设备的请求信息后，通过网管设备提供 的网关标识，在建立并维护好的路由表中进行搜索，如若该网管设备提供的网关标识在该路由表中，则根据路由表中的对应关系确定与该网关标识对应的出端口信息，并将该出端口信息返回网管设备，完成出端口信息的收集。本实施例中连接网管设备的出端口信息中既包括网元间接与网管设备连接的出端口信息，还包括网元直接与网管设备连接的出端口信息。
步骤S13：根据出端口信息在微波网络的拓扑结构中筛选出微波网络的根节点，其中，根节点的出端口信息未包含在微波网络的链路端口信息中。
由于拓扑结构中微波网络的链路端口信息是指微波网络中两两网元之间的链路端口信息，因此，微波网络的链路端口信息中不包括网元直接与网管设备连接的出端口信息。而连接网管设备的出端口信息中既包括网元间接与网管设备连接的出端口信息，还包括网元直接与网管设备连接的出端口信息。而根据根节点的定义可知，根节点与网管设备直接连接，因此，根据出端口信息在微波网络的拓扑结构中可筛选出微波网络的根节点，根节点的出端口信息未包含在微波网络的链路端口信息中。
一些例子中，根据出端口信息在微波网络的拓扑结构中筛选出微波网络的根节点，包括：遍历微波网络的拓扑结构并获取微波网络中所述链路端口信息；将出端口信息与链路的端口信息进行比较；将未包含在链路的端口信息中的出端口信息对应的网元确定为根节点。
本实施例中在网管设备获取网络拓扑所有网元的出端口后，遍历微波网络的拓扑结构，并获取微波网络中的链路端口信息，将网元反馈的出端口信息与链路端口信息进行比对，如若出端口信息包含在链路端口信息内，则说明该出端口信息的网元不是根节点；若出端口信息未包含在链路的端口信息中，则说明该出端口信息的网元为根节点。
本申请实施例提供的微波网络根节点查询方法，能够识别网管设备中所选网元所在的网络拓扑并存储相关信息，完成网元与网管设备按指定接口信息的交互，比对端口信息与网络链路端口信息确定根节点。这样，就可以在网络管理层面上掌握目标网元所在网络拓扑的根节点集合，从而有效加强了对网络的管理。且实现了微波网络根节点自动查询，无需人工介入，根节点查询的及时性较高，所查询到的根节点的可靠性也较高。
下面结合图2，通过具体实施对本申请提供的微波网络根节点查询方法进行详细说明。
网管设备收集网元1、网元2、网元3、网元4的网元信息，并收集链路12、链路13、链路34的链路信息。
用户确定目标网元1后，依据链路首末节点信息先计算出所有连通网元并存储网元信息及链路信息，根据链路12及链路13的链路信息，可识别网元1的所有连通网元，即网元2和网元3，整个网络拓扑结构需要存储的信息为网元1、网元2、网元3以及链路12、链路13；重复上述步骤，进而识别网元4及链路34，完成整个网络拓扑的识别。
网管设备向网元1、网元2、网元3、网元4按约定接口发送出端口查询请求，按组网情况，网元依次返回出端口信息为出端口1、出端口2、出端口3、出端口4。网管设备接收网元返回消息后进行计算，所有出端口中，只有出端口1未包含在已知网络拓扑的链路中，进而确定该端口1所在网元1为根节点，遍历全网，直至找到所有根节点。
本实施例中依托网管设备，能够快速、有效地自动识别出微波网元所在的网络拓扑并找到整个网络拓扑的根节点，避免因更改根节点网元配置而导致的整个网络断链失联的情况产生，提升了微波通信网络的健壮性。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些 步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本申请的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该申请的保护范围内。

在一些例子中，交互单元12包括：发送子单元121，发送子单元121用于向微波网络中的网元发送端口查询请求，端口查询请求包含网管设备的网关标识，端口查询请求以供网元根据网关标识确定连接网管设备的出端口信息；接收子单元122，接收子单元122用于接收微波网络中的网元发送的连接网管设备的出端口信息。
