Description

修正地址获取来源的方法、装置及网关设备 技术领域
本公开涉及通信领域，具体而言，涉及一种修正地址获取来源的方法、装置及网关设备。
背景技术
网络运营商部署到用户家庭的网关设备，会配置多个局域网(Local Area Network，简称LAN)侧端口挂载不同的设备。而家庭网关在出厂配置时，有的端口只能走二层转发数据流，有的只能走路由转发数据流。
对于只能走二层转发的端口，该端口挂载的设备只能通过internet获取地址才能正常转发数据；如果家庭网关给该设备分配了家庭网关地址，则就无法正常收发数据。
对于只能走路由转发的端口，该端口挂载的设备只能从家庭网关获取地址才能正常转发数据；如果设备从internet获取了地址，则可能就无法正常收发数据。
对于某个LAN口下挂的设备，是从家庭网关获取地址，还是从internet获取地址，是可以通过媒介(tr069,web,omci)配置的。通过tr069和web下发给网关的配置，是可以在设备中保存的；而对于光网络单元管理控制接口(ONU Management and Control Interface，简称omci)下发的配置，是不在设备中保存的，在设备重启后需要重新下发配置。
对于omci而言，在网关完成重启后才能下发配置，如果某一LAN口只能走二层数据流，那么就出现这种情况：在omci下发命令前，下挂设备已经从家庭网关获取到了地址，就不再从internet获取地址了，导致下挂设备一致使用的是网关地址，不能上网。
针对相关技术中由于无法在对各个端口下挂设备在分配错来源地址，造成设备无法正常收发数据的问题，目前尚未提出有效的解决方案。
发明内容

实施例1
本申请实施例1所提供的方法实施例可以在网关设备、计算机终端或者类似的运算装 置中执行。以运行在网关设备上为例，图1是本公开实施例的一种修正地址获取来源的方法的网关设备的硬件结构框图。如图1所示，网关设备10可以包括一个或多个(图中仅示出一个)处理器102(处理器102可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)、用于存储数据的存储器104、以及用于通信功能的传输装置106。本领域普通技术人员可以理解，图1所示的结构仅为示意，其并不对上述电子装置的结构造成限定。例如，网关设备10还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。
存储器104可用于存储应用软件的软件程序以及模块，如本公开实施例中的修正地址获取来源的方法对应的程序指令/模块，处理器102通过运行存储在存储器104内的软件程序以及模块，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器104可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些示例中，存储器104可进一步包括相对于处理器102远程设置的存储器，这些远程存储器可以通过网络连接至网关设备10。上述网络的示例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置106用于经由一个网络接收或者发送数据。上述的网络示例可包括网关设备10的通信供应商提供的无线网络。在一个示例中，传输装置106包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个示例中，传输装置106可以为射频(Radio Frequency，RF)模块，其用于通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述网关设备的方法，图2是根据本公开实施例的修正地址获取来源的方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，在网关设备重启的情况下，判断外接设备获取的地址是否由目标站点分配；
步骤S204，在判断结果为否的情况下，依据预设过滤规则丢弃非目标站点发送的报文；
步骤S206，获取目标站点分配的地址。
由上可知，结合步骤S202至步骤S206中，本申请实施例提供的修正地址获取来源的方法可以适用于部署有网关设备的通信网络，其中，在本申请实施例中该网关设备可以为家庭网关设备(Home Gateway，简称HG)，这里本申请实施例中的外接设备可以为任一移动终端，其中，该移动终端可以为：智能手机、笔记本电脑、个人电脑(Personal Computer，简称PC)、掌上商务、平板电脑或智能穿戴设备。
示例性的，网关设备以HG为例，外接设备以PC为例进行说明，在HG重启的情况下，判断PC获取的地址是否由目标站点分配，即，由于在omci下发的配置过程中，只能在网关(这里可以为HG)完成重启后才能下发配置，如果某一LAN口只能走二层数据流，那么就出现这种情况：在omci下发命令前，外接设备(这里可以为PC)已经从 HG获取到了动态主机配置协议(Dynamic Host Configuration Protocol，简称DHCP)地址，就不在从internet获取地址了，因此需要判断当前PC获取的地址是否为Internet分配的地址(即，本申请实施例中判断外接设备获取的地址是否由目标站点分配)；在判断结果为否的情况下，说明当前PC获取的地址不是Internet分配的地址，因此需要依据预设过滤规则丢弃非Internet往来的报文，即，对于需要发送给家庭网关地址续租报文全部丢弃，对于需要转发给internet的地址请求报文，全部放行。这样下挂设备续租地址将会不成功，导致重新获取地址，此时获取的地址便是internet分配的地址，能正常上网。基于上述，解决了只能走二层数据流的LAN口下挂设备，在先获取到网关分配地址的情况下，修正下挂设备的地址来源为internet，保证下挂设备正常上网。
本申请实施例提供的修正地址获取来源的方法中，由于在网关设备重启的情况下，判断外接设备获取的地址是否由目标站点分配；在判断结果为否的情况下，依据预设过滤规则丢弃非目标站点发送的报文；获取目标站点分配的地址，因此，可以解决相关技术中由于无法在对各个端口下挂设备在分配错来源地址，造成设备无法正常收发数据问题，达到设备通过获取正确的来源地址，收发数据的效果。
可选地，步骤S202中判断外接设备获取的地址是否由目标站点分配包括：
Step1，监听当前端口配置类型；
Step2，在配置类型为光网络单元管理控制接口omci的情况下，获取omci的控制类型；
Step3，在判断omci的控制类型为控制外接设备由目标站点获取地址的情况下，判断外接设备获取的地址是否由目标站点分配。
这里Step3中，在实现本申请实施例提供的修正地址获取来源的方法中，可以先判断omci的控制类型是否为控制外接设备由目标站点获取地址，进一步的判断该外接设备获取的地址是否由目标站点分配。
进一步地，可选的，步骤S204中依据预设过滤规则丢弃非目标站点发送的报文包括：
Step1，在控制类型为控制外接设备由目标站点获取地址的情况下，丢弃非目标站点发送的报文。
可选的，在步骤S202中判断外接设备获取的地址是否由目标站点分配之前，本申请实施例提供的修正地址获取来源的方法还包括：
步骤S200中，将网关设备分配地址的第一租期修改为第二租期，其中，第二租期小于第一租期，且第二租期，用于确保外接设备在预设时间内续租地址租期。
进一步的，可选的，本申请实施例提供的修正地址获取来源的方法还包括：
步骤S201，配置定时器；
步骤S203，在定时器计时完成后，将网关设备分配地址的租期由第二租期恢复至第一租期。
可选的，定时器计时包括：倒数计时或累计计时。
综上，结合步骤S202至步骤S206，本申请实施例提供的修正地址获取来源的方法示例如下。
图3是根据本公开实施例的修正地址获取来源的方法中系统架构的结构示意图，如图3所示，在实现本申请实施例提供的修正地址获取来源的方法中可以包括：下挂在网关设备31下的下挂设备32，以及与网关设备31连接的Internet服务器33，其中，如图3所示，本申请实施例提供的下挂设备32可以为PC，网关设备31可以为家庭网关设备HG，基于图3，在由HG和PC组成的网络中得到一个局域网LAN，HG与Internet服务器连接使得连接于该HG的PC可以通过该HG接入Internet服务器。
图4是根据本公开实施例的一种修正地址获取来源的方法的流程图，如图4所示，本申请实施例提供的HG以携带有Linux内核为例进行说明，基于图4，HG接收下挂于该HG的设备地址请求报文(S401)，判断该下挂设备地址请求报文的目标站点，在该目标站点为HG的情况下，即，判断该下挂设备地址请求报文是否发送至HG(S401)，若是，则将该下挂设备地址请求报文发送至HG(S403)，若否，则丢弃(S406)；在该目标站点为Internet服务器的情况下，即，判断该下挂设备地址请求报文是否发送至Internet服务器(S404)，若是，则将该下挂设备地址请求报文经由HG发送至Internet服务器(S405)，若否，则丢弃(S406)。
图5是根据本公开实施例的另一种修正地址获取来源的方法的流程图，如图5所示，基于图4，在图5中，本申请实施例提供的修正地址获取来源的方法通过修改分配地址的租期(S502)，缩短每个地址的租期，并在HG重启(S501)后开启预先配置的定时器(S503)，同时，检测下挂于该HG的下挂设备从网关获取的地址(S504)，判断是否为omci下发的配置(S505)，若是，则已经预设过滤规则，过滤非Internet服务器的报文(S506)，并丢弃该报文，以使得下挂设备续租地址失败(S507)，进而下挂设备将重新获取由Internet服务器分配的地址(S508)，从而下挂设备正常上网(S509)；若下挂于该HG的下挂设备从网关获取的地址并非omci下发的配置，则判断下挂设备是否需要续租地址的租期(S510)，若是，从网关获取地址(S504)。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例所述的方法。
