本公开基于2022年04月02日提交的发明名称为“数据报文转发方法、装置、存储介质及电子装置”的中国专利申请CN202210346858.8，并且要求该专利申请的优先权，通过引用将其所公开的内容全部并入本公开。
本公开实施例涉及通信领域，具体而言，涉及一种数据报文转发方法、装置、存储介质及电子装置。
由于Wi-Fi覆盖、网线质量、接口速率等诸多限制，用户选择的高宽带套餐，未能充分转化为在家庭随时随地的千兆极致体验。不少用户有意识地通过增加Wi-Fi热点数量改善房间的网络体验，常见的方案有增加大发射功率的接入点(Access Point，简称为AP)、Wi-Fi无线中继、电力猫、使用网线把多台AP连接起来等。这些方案能解决一些需求，但并非最优方案，在可靠、运维方面依然存在问题。
在这种情况下，光纤到户(Fiber to the Room，简称为FTTR)技术方案应运而生。相比于传统的网线组网技术，FTTR全光网络解决方案优势显著。其可以直接将光纤延伸至每个房间，是当前业界唯一可以实现全屋千兆以上覆盖能力的新技术。
FTTR全光网络一般由局端光线路终端(optical line terminal，简称为OLT)、FTTR光网关以及边缘光网络单元(Optical Network Unit)，简称为ONU)组成。FTTR光网关一般包含若干个2.5G以太口、1G以太口，同时再用一个扩展的物理口配合部分OLT的功能对接下面的若干个边缘ONU。当前的普通光网关只能处理物理以太口的数据报文交换，FTTR光网关和普通光网关相比引入了边缘ONU，那么如何有效处理普通以太口和边缘ONU之间、多个边缘ONU之间的数据交换就成了FTTR光网关急需解决的问题。
针对相关技术中FTTR光网关如何处理普通以太口和边缘ONU之间、多个边缘ONU之间的数据的问题，尚未提出解决方案。

在本实施例中提供了一种运行于上述移动终端或网络架构的数据报文转发方法，图2是根据本公开实施例的数据报文转发方法的流程图，如图2所示，该方法的执行主体是光网关，该流程包括如下步骤：
步骤S202，通过与第一边缘ONU的业务Gemport一一对应的Gemport端口接收所述第一边缘ONU发送的数据报文；
步骤S204，根据所述数据报文的目的MAC地址从MAC地址表中查找目的转发端口，其中，所述MAC地址表中存储有源MAC地址与Gemport端口的对应关系；
步骤S206，在查找到所述目的转发端口的情况下，通过所述目的转发端口将所述数据报文发送给第二边缘ONU。
通过上述步骤S202至S208，可以解决相关技术中FTTR光网关如何处理普通以太口和边缘ONU之间、多个边缘ONU之间的数据的问题，实现了和边缘ONU之间、多个边缘ONU之间的数据交换。
本公开实施例中，上述步骤S204具体可以包括：在对所述数据报文进行硬件处理的情况下，根据所述数据报文的目的MAC地址从硬件MAC地址表中查找目的转发端口，其中，所述硬件MAC地址表中存储有源MAC地址与pGemport端口的对应关系；在对所述数据报文进行软件处理的情况下，根据所述数据报文的目的MAC地址从软件MAC地址表中查找目的转发端口，其中，所述软件MAC地址表中存储有源MAC地址与vGemport端口的对应关系。
在一实施例中，在未查找到所述目的转发端口的情况下，在所有LAN口和Gemport端口对所述数据报文进行洪范，具体的，在对所述数据报文进行硬件处理的情况下，将所述数据报文发送到所有LAN口和Gemport端口，即在所有LAN口和pGemport端口对所述数据报文进行洪范；在对所述数据报文进行软件处理的情况下，在所有LAN口和vGemport端口对所述数据报文进行洪范。
在另一实施例中，在上述步骤S202之后，提取所述数据报文的源MAC地址；判断所述MAC地址表中是否存在所述源MAC地址；在所述MAC地址表中不存在所述源MAC地址的情况下，将所述源MAC地址与所述Gemport端口的对应关系存储到所述MAC地址表中。在所述MAC地址表中存在所述源MAC地址的情况下，更新所述源MAC地址所在条目的状态信息。
在另一实施例中，以预设时间周期根据所述MAC地址表中所述状态信息对所述源MAC地址所在条目进行老化处理。
在另一实施例中，在上述步骤S202之前，所述方法还包括：上电之后，创建软件口与硬件口；使能所述软件口与所述硬件口的接收报文功能以及MAC地址学习和转发功能，以完成系统初始化，使能之后，硬件口和软件口具备MAC地址学习功能以及转发功能。
图3是根据本公开实施例的XGPON下挂ONU系统的示意图，如图3所示，XGPON ONU下挂GPON ONU。边缘ONU一般使用GPON ONU，在GPON系统中会有0-4095共4096个Gemport作为业务通道，在FTTR光网关上创建4096个Gemport端口，并和边缘ONU的业务Gemport一一对应。这样FTTR光网关收到来自边缘ONU特定Gemport的数据报文时，会把报文的源MAC和Gemport端口学习到MAC地址表中用作后续的MAC地址查找和转发。对于需要转发到某个Gemport端口的数据报文，也会根据Gemport端口号做GEM帧封装并发送到边缘ONU。本公开实施例中光网关数据交换主要包括系统初始化、硬件数据交换、软件数据交换以及MAC地址表的老化。
系统初始化，具体包括：光网关上电后，首先硬件创建4096个物理端口，命名为pGemportO-pGemport4095。接着软件创建4096个软件口，命名为vGemportO-vGemport4095。在软件口和硬件口均创建完成后，再使能硬件口和软件口的接收报文功能以及MAC地址学习和转发功能。在系统初始化完成前，硬件口和软件口均不能接收报文，也不能学习MAC地址和转发报文。图4是根据本公开实施例的系统初始化的流程图，如图4所示，具体可以包括：
S401，光网关上电；
S402，硬件创建pGemportO-pGemport4095共4096个硬件口；
S403，软件创建vGemportO-vGemport4095共4096个软件口；
上述步骤S402与S403没有固定的先后顺序，可以先执行步骤S402，也可以先执行步骤S403。
S404，使能硬件口和软件口的MAC地址学习功能以及转发功能。
硬件数据交换的转发，光网关硬件收到来自边缘ONU的数据流时，会把数据流的源MAC地址以及与其对应GEMPORT学习到硬件地址表里面，形成一个源MAC+pGemport物理端口的地址条目。针对来自光网关LAN口以及PON口的数据流也会把数据流的源MAC以及对应的端口学习到硬件地址表中。这样就能在光网关上实现基于MAC地址的硬件报文交换，对于需要转发到某个pGemport端口的报文，需要打上对应的Gemport值，并做GEM帧封装后发往对应的边缘ONU。图5是根据本公开实施例的FTTR场景下硬件数据交换的流程图，如图5所示，硬件数据交换包括：
S501，光网关收到来自边缘ONU的数据报文；
S502，提取数据报文的源MAC，判断硬件地址表中是否已经有了本MAC地址；
S503，如果硬件地址表中没有本MAC地址，把本MAC地址和收到该数据报文的pGemport口学习到硬件MAC地址表中；
S504，更新MAC地址表的状态标记，如果硬件地址表中已经存在本MAC地址条目，那么把该条目的状态信息更新以表明本条目在用，在地址老化过程中会参考该状态信息；
S505，判断报文是否需要送到CPU进行软件处理；
S506，如果不需要送CPU软件处理，那么直接查找硬件MAC地址表以查找目的转发端口；
S507，报文需要送CPU进行软件处理；
S508，在硬件MAC地址表中没有找到转发目的端口，在所有LAN口和pGemport口进行洪
范：
S509，在硬件MAC地址表中找到目的端口后，把报文转发到该目的端口(可能为LAN口或pGemport口)。
软件数据交换的转发，除了硬件直接转发的数据报文之外，还有一部分报文需要由光网关的软件进行处理。相应的，来自边缘ONU的数据报文在经过pGemport送到光网关软件处理时，会进入到对应的vGemport，然后光网关的软件会学习报文的源MAC和vGemport到软件地址表。针对来自光网关LAN口以及PON口的数据流也会把数据流的源MAC以及对应的端口学习到软件地址表中。这样就能实现基于MAC地址的软件报文交换，对于需要转发到某个vGemport的数据报文，先发送到对应的pGemport，再做GEM帧封装并发往对应的边缘ONU。图6是根据本公开实施例的FTTR场景下软件数据交换的流程图，如图6所示，软件数据交换包括：
S601，光网关收到来自边缘ONU的数据报文；
S602，提取数据报文的源MAC，判断软件地址表中是否已经有了本MAC地址；
S603，软件地址表中没有本MAC地址，把MAC地址和收到该报文的vGemport口学习到软件MAC地址表中；
S604，更新MAC地址表的状态标记，软件地址表中已经存在本MAC地址条目，那么把该条目的状态信息更新以表明本条目在用，在地址老化过程中会参考该状态信息；
S605，查找软件MAC地址表以获取目的转发端口；
S606，在软件MAC地址表中没有找到转发目的端口，在所有LAN口和vGemport口进行洪范；
S607，在软件MAC地址表中找到目的端口后，把报文转发到该目的端口(可能为LAN口或vGemport口)。
硬件地址表和软件地址表的老化，光网关硬件以及软件上学习到的MAC地址，需要支持老化机制。在一定时间内(比如5分钟，值可配)，如果没有该MAC地址的报文传输，那么对应的MAC地址需要自行老化。
本公开实施例沿用原有的MAC地址交换模型，不需要修改光网关交换模型。并且不需要修改报文的内容，实现简单，不占用额外带宽，可以提升带宽利用率，并且如果后续边缘ONU采用EPON、XGPON、XGSPON或50G PON等ONU时也便于根据其业务Gemport的范围进行扩展。
