Description

一种三四地址路由器及其下挂设备管理方法及装置 【技术领域】
本发明涉及宽带终端设备组网技术领域,特别是涉及一种三四地址路由器及其下挂设备管理方法及装置。
【背景技术】
传统场景主网关/主路由直接下挂手机、电脑、机顶盒等设备,这类设备在获取IP地址时使用物理地址,无线模块、协议模块、驱动模块抓取的信息交互均以物理地址唯一标识一个设备,管理模块可统一管理。
随着组网需求的出现,路由器作为网络节点,利用无线分布式系统(Wireless Distribution System,简写:WDS)技术,路由器之间可以舍弃传统的有线网络进行互联,与主网关构成了完整的组网场景,主网关需管理包括路由器及其下挂设备在内的所有设备。对于WDS的实现方式,协议中没有明确的规定,但在无线数据帧头中,预留了地址位置。因此,所有的无线数据帧中都有四个地址域,仅使用前三个域,称为三地址,使用四个域称为四地址,当前本行业内均使用三地址或四地址作为无线链路数据帧封装方式。无线数据传输时必要的三个数据为DA(Destination Address,目标地址),SA(Source Address,源地址),BSSID(Basic Service Set Identifier,基本服务集标识符),因三地址只使用前三个域存储信息,造成无法存物理地址,而采用四地址无线链路数据帧封装方式则可同时存储DA、SA、RA(Receiver Address,接收端地址)和TA(Transmission Address,发送端地址)。
假设有组网环境如下:主网关-子路由器-下挂设备串行连接,三/四地址在通信时DA均存储的目标地址。
对于三地址路由器(即子路由器):下挂设备发出的报文原本在SA中存储下挂设备的物理地址,BSSID存储三地址路由器无线地址,但报文经过三地址路由器后,SA被更改为存储三地址路由器的无线地址,BSSID存储主网关的无线地址,造成了下挂设备物理地址的丢失。主网关接收到的MAC消息,携带为子路由器的无线地址以及子路由器接入端口,地址解析协议消息交互报文携带子路由器无线地址以及子路由器或其下挂设备获取到的IP地址,配置协议消息不受组网模式影响,交互报文携带路由器或其下挂设备的物理地址以及路由器或其下挂设备获取到的IP地址。
对于四地址路由器(即子路由器);下挂设备发出的报文在SA中存储下挂设备的物理地址,BSSID存储四地址路由器无线地址,报文经过四地址路由器后,SA保持不变,RA存储四地址路由器的无线地址,TA存储主网关的无线地址,下挂设备的物理地址没有丢失。主网关接收到的MAC消息,携带为子路由器的无线地址以及子路由器接入端口,地址解析协议消息交互报文携带子路由器或子路由器下挂设备的物理地址以及子路由器或其下挂设备获取到的IP地址, 配置协议消息不受组网模式影响,交互报文携带路由器或其下挂设备的物理地址以及路由器或其下挂设备获取到的IP地址。
鉴于此,克服该现有技术所存在的缺陷是本技术领域亟待解决的问题。
【发明内容】
本发明要解决的技术问题是:
三四地址路由器及其下挂设备管理,仅通过MAC地址(其中MAC地址包括物理地址和无线地址)作为唯一标识,会由于MAC消息(携带无线无线地址)、地址解析协议消息(三地址路由器携带无线地址,四地址路由器携带物理地址)、配置协议消息(携带物理地址)中携带的MAC地址不一致无法标识同一子路由器及其下挂设备。现有技术中,若要实现子路由器及其下挂设备的管理,则需新增私有协议用于主网关与子路由器及其下挂设备之间通信,使用场景受限,无法实现不同厂家组网路由器及其下挂设备管理。

此外,下面所描述的本发明各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
实施例1:
本发明实施例1提供了一种三四地址路由器及其下挂设备管理系统,该包括主网关、子路由器和子路由器的下挂设备,其中,如图1所示,主网关包括管理模块、事件告警模块、无线模块、协议模块和驱动模块。
无线模块:在子路由器(不包含子路由器的下挂设备,因为子路由器的下挂设备的实际接入点为子路由器,而不是主网关,因此主网关无法收到子路由器下挂设备接入子路由器时的MAC消息)接入主网关时,主网关的无线模块可获取到子路由器的MAC地址(此处的MAC地址为无线地址)以及子路由器接入主网关的接入端口,并将子路由器的MAC地址和子路由器接入主网关的接入端口上报给事件告警模块,事件告警模块统一打包信息并以MAC消息的形式上报给管理模块,即MAC消息中包含子路由器的无线地址和子路由器接入主网关的接入端口。
协议模块:在子路由器或者子路由器的下挂设备接入系统后进行动态IP地址获取时,该协议模块可获取到子路由器或者子路由器的下挂设备的MAC地址 (此处的MAC地址为物理地址)和IP地址,并将子路由器或者子路由器的下挂设备的MAC地址和IP地址上报给事件告警模块,事件告警模块统一打包信息并以配置协议消息的形式上报给管理模块,即配置协议消息中包含子路由器或者子路由器的下挂设备的物理地址和IP地址。
驱动模块:在子路由器或者子路由器的下挂设备接入后产生数据交互时,对于三地址路由器而言,该驱动模块可获取到子路由器或者子路由器的下挂设备的MAC地址(此处的MAC地址为无线地址)和IP地址,其中子路由器或者子路由器的下挂设备的无线地址相同(子路由器本身有两个地址,一个为物理地址,一个为无线地址,这两个地址均为MAC地址,子路由器本身与主网关进行交互时,使用无线地址,子路由器的下挂设备发送的与主网关的交互报文通过子路由器之后,子路由器的下挂设备的物理地址被子路由器统一转化为子路由器的无线地址,因此子路由器或者子路由器的下挂设备与主网关信息交互时均使用子路由器的无线地址,本实施例所说的子路由器的下挂设备的无线地址均为子路由器的无线地址),该驱动模块将子路由器或者子路由器的下挂设备的无线地址和IP地址上报给事件告警模块,事件告警模块统一打包信息并以地址解析协议消息的形式上报给管理模块,即对于三地址路由器而言,地址解析协议消息中包含子路由器或者子路由器的下挂设备的无线地址和IP地址,同时子路由器接入系统时,驱动模块会生成包含子路由器的无线地址和子路由器接入主网关的接入端口的网桥地址表(对三地址路由器而言,如背景技术中举例描述,因主网关接收到的报文中仅包含子路由的无线地址,不包含下挂设备的物理地址,故驱动模块无法获取到下挂设备的物理地址生成网桥地址表)。
对于四地址路由器而言,该驱动模块可获取到子路由器或者子路由器的下挂设备的MAC地址(此处的MAC地址为物理地址)和IP地址,事件告警模块统一打包信息并以地址解析协议消息的形式上报给管理模块,即对于四地址路由器而言,地址解析协议消息中包含子路由器或者子路由器的下挂设备的物理地址和IP地址,同时子路由器或者子路由器的下挂设备接入系统时,驱动模块便会生成包含子路由器或者子路由器的下挂设备的物理地址和子路由器接入主网关的接入端口的网桥地址表(对四地址路由器而言,如背景技术中举例描述,因主网关接收到的报文中包含子路由的无线地址,且包含下挂设备的物理地址,故驱动模块可以获取到下挂设备的物理地址生成网桥地址表)。
事件告警模块:负责统一打包信息并封装对应消息格式,转发对应消息给管理模块。
管理模块:负责汇总子路由器和子路由器的下挂设备的消息,经过信息匹配,标识并记录子路由器或子路由器的下挂设备信息,对于子路由器或者子路由器的下挂设备的唯一标识,只需要获取到子路由器或者子路由器的下挂设备的物理地址、IP地址和接入端口构成的唯一标识信息后便可对设备进行唯一标 识。
本实施例提供了一种三四地址路由器及其下挂设备管理方法,包括配置协议消息、网络地址表、MAC表和网桥地址表中的多项,其中,所述配置协议消息包括MAC地址和IP地址;
使用配置协议消息的MAC地址在网桥地址表中匹配相同的MAC地址,若根据配置协议消息的MAC地址在网桥地址表未匹配到相同的MAC地址,说明发送该配置协议消息的设备为三地址路由器或者三地址路由器的下挂设备,若根据所述配置协议消息的MAC地址在网桥地址表中匹配到的相同的MAC地址,说明发送该配置协议消息的设备为四地址路由器或者四地址路由器的下挂设备,此时获取所述匹配到的网桥地址表中的MAC地址对应的行记录中的接入端口,由于配置协议消息的MAC地址为物理地址,因此可根据配置协议消息的MAC地址、配置协议消息的IP地址和网桥地址表中匹配到的接入端口对设备进行标识,本实施例提供一种实际场景中可实现的方式,具体包括:
假设管理模块获取配置协议消息中包含的MAC地址和IP地址分别为54:f2:94:1b:93:22和192.168.1.11,其中,配置协议消息中包含的MAC地址为物理地址,根据配置协议消息中的MAC地址54:f2:94:1b:93:22从网桥地址表中匹配相同的MAC地址,假设网桥地址表中含有“54:f2:94:1b:93:22,PORT1”这一条行记录,则可在网桥地址表中匹配到与54:f2:94:1b:93:22相同的MAC地址,匹配到之后取出“54:f2:94:1b:93:22,PORT1”这一条行记录中的PORT1(即接入端口),由于配置协议消息包含的MAC地址为物理地址,因此可将配置协议消息的MAC地址54:f2:94:1b:93:22、配置协议消息的IP地址192.168.1.11和在网桥地址表中匹配到的接入端口PORT1作为设备标识信息,对设备进行标识。若根据所述配置协议消息在网桥地址表中未匹配到相同的MAC地址,则表示该配置协议消息是由三地址路由器或者三地址路由器的下挂设备发出的。
如图2和图3所示,所述网络地址表由配置协议消息和地址解析协议消息生成,配置协议消息中包含MAC地址和IP地址,其中所述配置协议消息中包含的MAC地址为物理地址,地址解析协议消息中包含:MAC地址和IP地址,其中,对于三地址路由器或者三地址路由器的下挂设备而言,地址解析协议消息中的MAC地址为无线地址,对于四地址路由器或者四地址路由器的下挂设备而言,地址解析协议消息中的MAC地址为物理地址,因此,对于三地址路由器或者三地址路由器的下挂设备而言,由配置协议消息和地址解析协议消息生成的网络地址表中包含IP地址和两个MAC地址(物理地址和无线地址)。对于四地址路由器或者四地址路由器的下挂设备而言,网络地址表中仅包含IP地址和一个MAC地址(物理地址)。
MAC表由MAC消息生成,由于MAC消息包含子路由器的MAC地址(无线地址)和接入端口,因此MAC表中也包含子路由器的MAC地址(无线地址) 和接入端口。
当三地址路由器(即子路由器)接入主网关或者主路由时,本实施例以接入主网关为例进行说明,生成包含子路由器的MAC地址(无线地址)和子路由器接入端口的网桥地址表,当四地址路由器(即子路由器)或者四地址路由器的下挂设备接入组网时,生成包含子路由器或者子路由器的下挂设备的MAC地址(物理地址)和子路由器接入端口的网桥地址表,本实施例涉及的接入端口均为子路由器与主网关接入时的接入端口,本实施例涉及的物理地址均为子路由器或者子路由器的下挂设备的物理地址。
在管理模块接收到路由器或路由器的下挂设备的消息时,首先判断接收到的消息类型,消息类型总体分为三种:配置协议消息、地址解析协议消息和MAC消息,因子路由器或子路由器的下挂设备获取地址及信息交互存在一定时间延迟,管理模块接收到三个消息没有固定的先后顺序,管理模块每接收到任意一个消息时,发起一轮信息匹配,本实施例涉及的IP地址均为子路由器或者子路由器的下挂设备的IP地址,涉及的三地址路由器和四地址路由器均为子路由器。根据物理地址、IP地址和接入端口中的多项对设备进行标识。
如图4所示,步骤10,获取配置协议消息,若根据所述配置协议消息在网桥地址表中未匹配到相同的MAC地址,则根据所述配置协议消息的IP地址在网络地址表中匹配不同的MAC地址;
配置协议消息发起的匹配:管理模块获取配置协议消息,该配置协议消息包含MAC地址和IP地址,其中,配置协议消息的MAC地址为物理地址,根据配置协议消息中的MAC地址匹配网桥地址表中的MAC地址(即判断在网桥地址表中是否含有与配置协议消息中的MAC地址相同的MAC地址对应的行记录),若根据所述配置协议消息在网桥地址表中匹配到相同的MAC地址(表示该配置协议消息是由四地址路由器或者四地址路由器的下挂设备发出的)则获取所述匹配到的网桥地址表中的MAC地址对应的行记录中的接入端口,以便获取物理地址、IP地址和接入端口对设备进行标识;
本实施例提供一种实际场景中可实现的方式,具体为:
假设管理模块获取配置协议消息中包含的MAC地址和IP地址分别为54:f2:94:1b:93:22和192.168.1.11,根据配置协议消息中的MAC地址54:f2:94:1b:93:22从网桥地址表中匹配相同的MAC地址,假设网桥地址表中含有“54:f2:94:1b:93:22,PORT1”这一条行记录,则可在网桥地址表中匹配到与配置协议消息的MAC地址54:f2:94:1b:93:22相同的MAC地址,匹配到之后取出“54:f2:94:1b:93:22,PORT1”这一条行记录中的PORT1(即接入端口),由于配置协议消息包含的MAC地址为物理地址,因此将配置协议消息的MAC地址54:f2:94:1b:93:22、配置协议消息的IP地址192.168.1.11和在网桥地址表中匹配到的MAC地址对应的行记录中的接入端口PORT1作为设备标识信息,对设 备进行标识。若根据所述配置协议消息在网桥地址表中未匹配到相同的MAC地址,即如根据配置协议消息中的MAC地址54:f2:94:1b:93:22无法从网桥地址表中匹配到有相同MAC地址的行记录(此时表示该配置协议消息是由三地址路由器或者三地址路由器的下挂设备发出的),则判断根据所述配置协议消息的IP地址在网络地址表中是否匹配不同的MAC地址;首先根据所述配置协议消息的IP地址192.168.1.11判断当前的网络地址表中是否含有与所述配置协议消息的IP地址192.168.1.11相同的行记录。
步骤20,若根据所述配置协议消息的IP地址在网络地址表中匹配到不同的MAC地址,则将所述配置协议消息中的MAC地址更新至在网络地址表中匹配到的不同的MAC地址对应的行记录;
具体为,根据所述配置协议消息的IP地址192.168.1.11判断当前的网络地址表中是否含有与所述配置协议消息的IP地址相同的行记录;假设网络地址表中含有“54:F2:94:1B:93:32,192.168.1.11”这一条行记录,则可在网络地址表中匹配到与配置协议消息的IP地址192.168.1.11相同的行记录,然后判断所述配置协议消息的MAC地址54:f2:94:1b:93:22与匹配到的行记录“54:F2:94:1B:93:32,192.168.1.11”中的MAC地址是否相同,由于“54:F2:94:1B:93:32,192.168.1.11”这一条行记录中的MAC地址为54:F2:94:1B:93:32,其与配置协议消息的MAC地址54:f2:94:1b:93:22不相同,此时将所述配置协议消息中的MAC地址54:f2:94:1b:93:22更新至“54:F2:94:1B:93:32,192.168.1.11”这一条行记录中,更新之后的网络地址表为54:F2:94:1B:93:32、54:f2:94:1b:93:22和192.168.1.11。
由于根据配置协议消息的IP地址192.168.1.11在网络地址表中匹配到的与配置协议消息的MAC地址54:f2:94:1b:93:22不同的MAC地址为54:F2:94:1B:93:32,因此根据MAC地址54:F2:94:1B:93:32在MAC表中匹配相同的MAC地址,即为了找到对应的接入端口。
步骤30,判断根据所述配置协议消息的IP地址在网络地址表中匹配到的不同的MAC地址在MAC表中是否匹配到相同的MAC地址;
步骤40,若根据所述配置协议消息的IP地址在网络地址表中匹配到的不同的MAC地址在MAC表中匹配到相同的MAC地址,则获取MAC表中匹配到的相同的MAC地址对应的接入端口,以便对设备进行标识。
假设当前的MAC表中含有“54:F2:94:1B:93:32,PORT1”这一条记录,则可根据所述配置协议消息的IP地址在网络地址表中匹配到的不同的MAC地址54:F2:94:1B:93:32在MAC表中匹配到相同的MAC地址对应的行记录“54:F2:94:1B:93:32,PORT1”,匹配到之后取出“54:F2:94:1B:93:32,PORT1”这一条行记录中的PORT1(即接入端口),其中根据所述配置协议消息的IP地址在网络地址表中匹配到的不同的MAC地址为无线地址,将配置协议消息的MAC地址54:f2:94:1b:93:22、配置协议消息的IP地址192.168.1.11和从MAC 表中取出的PORT1作为设备标识信息。
步骤50,若根据所述配置协议消息的IP地址在网络地址表中匹配到的不同的MAC地址在MAC表中未匹配到相同的MAC地址,则等待所述MAC表的更新。
如图5所示,若根据所述配置协议消息在网桥地址表中匹配到相同的MAC地址,具体包括:所述网桥地址表包括MAC地址和接入端口,其中所述网桥地址表中的MAC地址包括无线地址、物理地址;
步骤101,根据所述配置协议消息中的MAC地址匹配网桥地址表中的MAC地址;
管理模块获取配置协议消息,该配置协议消息包含MAC地址和IP地址,其中,配置协议消息的MAC地址为物理地址,根据配置协议消息中的MAC地址匹配网桥地址表中的MAC地址(即判断在网桥地址表中是否含有与配置协议消息中的MAC地址相同的MAC地址对应的行记录)。
步骤102,若根据所述配置协议消息的MAC地址在网桥地址表中匹配到的相同的MAC地址(表示该配置协议消息是由四地址路由器或者四地址路由器的下挂设备发出的),则获取所述匹配到的网桥地址表中的MAC地址对应的行记录中的接入端口,以便对设备进行标识。
假设管理模块获取配置协议消息中包含的MAC地址和IP地址分别为54:f2:94:1b:93:22和192.168.1.11,其中,配置协议消息的MAC地址为物理地址,根据配置协议消息中的MAC地址54:f2:94:1b:93:22从网桥地址表中匹配相同的MAC地址,假设网桥地址表中含有“54:f2:94:1b:93:22,PORT1”这一条行记录,则可在网桥地址表中匹配到与配置协议消息的MAC地址54:f2:94:1b:93:22相同的MAC地址,匹配到之后取出“54:f2:94:1b:93:22,PORT1”这一条行记录中的PORT1(即接入端口),由于配置协议消息包含的MAC地址为物理地址,因此将配置协议消息的MAC地址54:f2:94:1b:93:22、配置协议消息的IP地址192.168.1.11和在网桥地址表中匹配到的MAC地址对应的行记录中的接入端口PORT1作为设备标识信息,对设备进行标识。
如图6所示,所述则根据所述配置协议消息的IP地址在网络地址表中匹配不同的MAC地址,具体包括:
步骤201,根据所述配置协议消息的IP地址判断当前的网络地址表中是否含有与所述配置协议消息的IP地址相同的行记录;
若根据所述配置协议消息在网桥地址表中未匹配到相同的MAC地址(此时表示该配置协议消息是由三地址路由器或者三地址路由器的下挂设备发出的),则根据所述配置协议消息的IP地址在网络地址表中匹配不同的MAC地址,首先根据所述配置协议消息的IP地址判断当前的网络地址表中是否含有与所述配置协议消息的IP地址相同的行记录。假设管理模块获取配置协议消息中包含的 MAC地址和IP地址分别为54:f2:94:1b:93:22和192.168.1.11,首先根据所述配置协议消息的IP地址192.168.1.11判断当前的网络地址表中是否含有与所述配置协议消息的IP地址192.168.1.11相同的行记录。
步骤202,若判断当前的网络地址表中含有与所述配置协议消息的IP地址相同的行记录,则判断所述配置协议消息的MAC地址与所述网络地址表中与配置协议消息的IP地址相同的行记录对应的MAC地址是否相同;
若判断当前的网络地址表中未含有与所述配置协议消息的IP地址相同的行记录,将所述配置协议消息中的MAC地址和IP地址存入网络地址表中,等待地址解析协议消息发起匹配并更新网络地址表。
假设网络地址表中含有“54:F2:94:1B:93:32,192.168.1.11”这一条行记录,则可在网络地址表中匹配到与配置协议消息的IP地址192.168.1.11相同的行记录“54:F2:94:1B:93:32,192.168.1.11”,然后判断所述配置协议消息的MAC地址54:f2:94:1b:93:22与匹配到的行记录“54:F2:94:1B:93:32,192.168.1.11”中的MAC地址是否相同。
步骤204,若不相同,则根据所述配置协议消息的IP地址在网络地址表中匹配到不同的MAC地址。
由于“54:F2:94:1B:93:32,192.168.1.11”这一条行记录中的MAC地址为54:F2:94:1B:93:32,其与配置协议消息的MAC地址54:f2:94:1b:93:22不相同,说明根据所述配置协议消息的IP地址在网络地址表中匹配到不同的MAC地址。
步骤203,若判断当前的网络地址表中未含有与所述配置协议消息的IP地址相同的行记录,则将所述配置协议消息存入当前的网络地址表中。
如图7所示,还包括地址解析协议消息,其中,所述地址解析协议消息包括MAC地址和IP地址。
步骤301,获取地址解析协议消息;
地址解析协议消息发起的匹配:管理模块获取地址解析协议消息,该地址解析协议消息包含MAC地址和IP地址,其中,地址解析协议消息包含MAC地址为无线地址,假设获取的地址解析协议消息中的MAC地址和IP地址分别为54:F2:94:1B:93:32和192.168.1.11。
步骤302,根据所述地址解析协议消息的IP地址判断当前的网络地址表中是否含有与所述地址解析协议消息的IP地址相同的行记录;
根据所述地址解析协议消息的IP地址判断当前的网络地址表中是否含有与所述地址解析协议消息的IP地址相同的行记录,如根据地址解析协议消息的IP地址192.168.1.11判断当前的网络地址表中是否含有与所述地址解析协议消息的IP地址相同的行记录,若判断当前的网络地址表中未含有与所述址解析协议消息的IP地址相同的行记录,则将所述地址解析协议消息存入当前的网络地址表中。假设网络地址表中含有“54:f2:94:1b:93:22,192.168.1.11”这一条行记录, 则可在网络地址表中匹配到与地址解析协议消息的IP地址192.168.1.11相同的行记录“54:f2:94:1b:93:22,192.168.1.11”。
步骤303,若判断当前的网络地址表中含有与所述地址解析协议消息的IP地址相同的行记录,则判断所述地址解析协议消息的MAC地址与所述网络地址表中与地址解析协议消息的IP地址相同的行记录对应的MAC地址是否相同;
具体为,根据地址解析协议消息中的IP地址192.168.1.11从网络地址表中匹配,假设网络地址表中含有“54:f2:94:1b:93:22,192.168.1.11”这一条行记录,则可在网络地址表中匹配到与地址解析协议消息中的IP地址192.168.1.11相同的行记录“54:f2:94:1b:93:22,192.168.1.11”,然后判断所述地址解析协议消息的MAC地址54:F2:94:1B:93:32与匹配到的行记录“54:f2:94:1b:93:22,192.168.1.11”中的MAC地址是否相同,即判断对应的物理地址是否已经存入网络地址表中。
步骤305,若不相同,将所述地址解析协议消息中的MAC地址更新至在网络地址表中匹配到的不同的MAC地址对应的行记录;
由于根据地址解析协议消息中的IP地址192.168.1.11从网络地址表中匹配到的相同IP地址的行记录为“54:f2:94:1b:93:22,192.168.1.11”,这一条行记录中的MAC地址为54:f2:94:1b:93:22,其与地址解析协议消息的MAC地址54:F2:94:1B:93:32不相同,说明对应的物理物理已经存入网络地址表中,行记录“54:f2:94:1b:93:22,192.168.1.11”中的MAC地址54:f2:94:1b:93:22为物理地址,将所述地址解析协议消息中的MAC地址54:F2:94:1B:93:32更新至“54:f2:94:1b:93:22,192.168.1.11”这一条行记录中,更新之后的网络地址表中便含有54:F2:94:1B:93:32、54:f2:94:1b:93:22和192.168.1.11。
步骤306,根据所述地址解析消息的MAC地址在MAC表中是否匹配到相同的MAC地址;
步骤307,若根据所述地址解析协议消息的MAC地址在MAC表中匹配到相同的MAC地址,则获取MAC表中匹配到的相同的MAC地址对应的接入端口,以便对设备进行标识。
假设当前的MAC表中含有“54:F2:94:1B:93:32,PORT1”这一条记录,则可根据地址解析协议消息的MAC地址54:F2:94:1B:93:32在MAC表中匹配到相同的MAC地址,匹配到之后取出“54:F2:94:1B:93:32,PORT1”这一条记录中的PORT1(即接入端口),将根据地址解析协议消息的IP地址匹配到的不同的MAC地址对应的行记录中的MAC地址(物理地址)54:f2:94:1b:93:22、IP地址192.168.1.11和从MAC表中取出的PORT1作为设备标识信息,步骤308,若根据所述地址解析协议消息的MAC地址在MAC表中未匹配到相同的MAC地址,则等待所述MAC表的更新。
步骤304,若判断当前的网络地址表中未含有与所述地址解析协议消息的IP 地址相同的行记录,则将所述地址解析协议消息存入当前的网络地址表中。
具体为,假设管理模块获取地址解析协议消息中包含的MAC地址和IP地址分别为54:F2:94:1B:93:32和192.168.1.11,根据地址解析协议中的IP地址192.168.1.11从网络地址表中匹配,无法匹配到与地址解析协议中的IP地址192.168.1.11相同的行记录,则将所述地址解析协议消息存入至当前的网络地址表中。
如图8所示,还包括MAC消息,其中所述MAC消息包括MAC地址和接入端口:
步骤401,获取MAC消息,将所述MAC消息更新至MAC表中;
MAC消息发起的匹配:管理模块获取MAC消息,所述MAC消息包含MAC地址和接入端口,其中MAC消息包含的MAC地址为无线地址,将MAC消息包含MAC地址和接入端口更新至MAC表中,假设获取的MAC消息中的MAC地址和接入端口分别为54:F2:94:1B:93:32和PORT1,则将MAC地址54:F2:94:1B:93:32和接入端口PORT1更新至MAC表中。
步骤402,根据所述MAC消息的MAC地址判断当前的网络地址表中是否含有与所述MAC消息的MAC地址相同的行记录。
假设获取的MAC消息中含有的MAC地址和接入端口分别为54:F2:94:1B:93:32和PORT1(MAC消息中含有的MAC地址为无线地址),当前的网络地址表中含有“54:F2:94:1B:93:32,54:f2:94:1b:93:22,192.168.1.11”这一条行记录(即发送MAC消息的设备对应的地址解析协议消息和配置协议消息均已存入至网络地址表中),则可判断当前的网络地址表中含有与所述MAC消息的MAC地址54:F2:94:1B:93:32相同的行记录。
若判断当前的网络地址表中含有与所述MAC消息的MAC地址相同的行记录,则判断当前的网络地址表中与所述MAC消息的MAC地址相同的行记录中是否含有与所述MAC消息的MAC地址不相同的MAC地址(即根据MAC消息中含有的无线地址查询对应的物理地址),若含有,则对设备进行标识。
判断当前的网络地址表中含有与所述MAC消息的MAC地址54:F2:94:1B:93:32相同的行记录之后,判断当前的网络地址表中的行记录“54:F2:94:1B:93:32,54:f2:94:1b:93:22,192.168.1.11”中是否含有与所述MAC消息的MAC地址54:F2:94:1B:93:32不同的MAC地址,可知,“54:F2:94:1B:93:32,54:f2:94:1b:93:22,192.168.1.11”还含有MAC地址54:f2:94:1b:93:22,该MAC地址54:f2:94:1b:93:22与MAC消息的MAC地址54:F2:94:1B:93:32不相同,可认定MAC地址54:f2:94:1b:93:22物理地址,然后将54:f2:94:1b:93:22、192.168.1.11和PORT1作为设备标识信息。以上所述即为本发明实施例提供的三四地址路由器及其下挂设备管理方法的完整过程。本实施例仅仅是举例说明,并不用于限定本发明。
实施例2:
本实施例还提供了一种三四地址路由器及其下挂设备管理方法的实施例,具体为:
如图15所示,假设将三地址路由器、手机1和手机2三台设备依次接入主网关构成三地址组网模式,本实施例以最常见的消息顺序为例,即管理模块依次收到MAC消息、配置协议消息和地址解析协议消息,然后根据接收到的三种消息对三台设备进行标识。
(1-1)如图9所示,将三地址路由器接入主网关:
三地址路由器接入主网关时会生成包含三地址路由器的MAC地址(此处的MAC地址为三地址路由器的无线地址)和接入主网关的接入端口的网桥地址表。
管理模块获取到MAC消息,所述MAC消息中携带MAC地址1A1B1C1D和接入端口PORT1,其中,MAC消息中携带MAC地址为无线地址,然后将所述MAC消息更新至MAC表中,本实施例假设更新至MAC表的行记录1中,根据所述MAC消息的MAC地址1A1B1C1D判断当前的网络地址表中是否含有与所述MAC消息的MAC地址1A1B1C1D相同的行记录,由于本实施例假设管理模块最先接收到MAC消息,因此当前的网络地址表中还未存入所述三地址路由器发送的地址解析协议消息,因此无法在网络地址表中查询到与所述MAC消息的MAC地址1A1B1C1D相同的行记录,此时等待三地址路由器发送的地址解析协议消息和/或配置协议消息发起匹配并更新网络地址表。
(注:本实施例中的MAC地址1A1B1C1D、1a1b1c1d等是为了阐述方便实例性的)
管理模块获取到配置协议消息,所述配置协议消息中携带MAC地址1a1b1c1d和IP地址192.168.1.1,其中,配置协议消息中携带MAC地址为物理地址,根据配置协议消息中的MAC地址1a1b1c1d匹配网桥地址表中的MAC地址(即判断在网桥地址表中是否含有与配置协议消息中的MAC地址相同的MAC地址对应的行记录),若根据所述配置协议消息的MAC地址1a1b1c1d在网桥地址表中匹配到相同的MAC地址,(表示该配置协议消息是由四地址路由器或者四地址路由器的下挂设备发出的),若根据所述配置协议消息的MAC地址1a1b1c1d在网桥地址表中未匹配到相同的MAC地址,即根据配置协议消息中的MAC地址1a1b1c1d无法从网桥地址表中匹配到有相同MAC地址的行记录(此时表示该配置协议消息是由三地址路由器或者三地址路由器的下挂设备发出的),由于本实施例假设接入的是三地址路由器,因此根据所述配置协议消息的MAC地址1a1b1c1d在网桥地址表中是无法匹配到相同的MAC地址的。此时根据所述配置协议消息的IP地址192.168.1.1判断当前的网络地址表中是否含有与所述配置协议消息的IP地址192.168.1.1相同的行记录,由于本实施例是假设管理模块先收到配置协议消息,因此管理模块还未收到三地路由器发出的 地址解析协议消息,那么根据所述配置协议消息的IP地址192.168.1.1在网络地址表中是无法找到相同的IP地址的,此时将所述配置协议消息的MAC地址1a1b1c1d和IP地址192.168.1.1存入当前的网络地址表中,等待地址解析协议消息发起匹配并更新网络地址表,本实施例假设所述配置协议消息的MAC地址1a1b1c1d和IP地址192.168.1.1已存入网络地址表的行记录1中。
管理模块获取到地址解析协议消息,所述地址解析协议消息中携带MAC地址1A1B1C1D和IP地址192.168.1.1,根据地址解析协议消息中的IP地址判断当前的网络地址表中是否含有与所述地址解析协议消息的IP地址相同的行记录;由于管理模块已经收到三地址路由器发出的配置协议消息,且已将配置协议消息的MAC地址1a1b1c1d和IP地址192.168.1.1存入网络地址表的行记录1中,因此可根据地址解析协议消息中的IP地址192.168.1.1在网络地址表中匹配到相同的IP地址,那么此时判断所述地址解析协议消息的MAC地址1A1B1C1D与所述网络地址表中与地址解析协议消息的IP地址相同的行记录对应的MAC地址是否相同,由于根据地址解析协议消息中的IP地址192.168.1.1在网络地址表中匹配到相同的IP地址的行记录为“1a1b1c1d,192.168.1.1”,可知,匹配到的行记录对应的MAC地址为1a1b1c1d,其与地址解析协议消息的MAC地址1A1B1C1D不同,由于地址解析协议消息携带的MAC地址1A1B1C1D为无线地址,那么行记录“1a1b1c1d,192.168.1.1”中的MAC地址1a1b1c1d物理地址,则将地址解析协议消息中的MAC地址1A1B1C1D更新至在网络地址表中匹配到的不同的MAC地址对应的行记录“1a1b1c1d,192.168.1.1”中,即网络地址表的行记录1中,(若根据地址解析协议消息中的IP地址192.168.1.1在网络地址表中匹配到相同的IP地址的行记录,且地址解析协议消息的MAC地址与所述网络地址表中与地址解析协议消息的IP地址相同的行记录对应的MAC地址是不相同,那么说明发出该地址解析协议消息的为三地址路由器或者三地址路由器的下挂设备发出的,而非四地址路由器或者四地址路由器的下挂设备发出的,且地址解析协议消息的MAC地址与所述网络地址表中与地址解析协议消息的IP地址相同的行记录对应的MAC地址为物理地址,即1a1b1c1d为物理地址)。将地址解析协议消息中的MAC地址1A1B1C1D更新至在网络地址表中匹配到的不同的MAC地址对应的行记录“1a1b1c1d,192.168.1.1”的行记录1之后,网络地址表的行记录1中便含有1A1B1C1D、1a1b1c1d和192.168.1.1。
最后使用地址解析协议消息的MAC地址在MAC表中匹配相同的MAC地址,若匹配到,则可获取MAC表中匹配到的相同的MAC地址对应的接入端口,以便对设备进行标识。即根据地址解析协议消息的MAC地址1A1B1C1D在MAC表中匹配相同的MAC地址,由于管理模块已经收到MAC消息,且MAC消息存入MAC表中,因此当前的MAC表中含有“1A1B1C1D,PORT1”这样一条行记录,则可地址解析协议消息的MAC地址1A1B1C1D在MAC表中匹配 相同的MAC地址对应的行记录“1A1B1C1D,PORT1”,匹配到之后取出“1A1B1C1D,PORT1”这一条行记录中的接入端口PORT1,将1A1B1C1D、1a1b1c1d,192.168.1.1和PORT1放入设备列表的行记录1中,根据1a1b1c1d、192.168.1.1和PORT1作为设备标识信息。当管理模块收到三地址路由器接入主网关时的MAC消息、配置协议消息和地址解析协议消息后:
MAC表含有行记录“1A1B1C1D,PORT1”;
网络地址表含有行记录“1A1B1C1D,1a1b1c1d,192.168.1.1”;;
网桥地址表含有行记录“1A1B1C1D,PORT1”。
设备列表中含有行记录“1A1B1C1D,1a1b1c1d,192.168.1.1,PORT1”,即设备列表的行记录1。
(1-2)如图10所示,将手机1接入三地址路由器:
三地址路由器的下挂设备接入系统时,驱动模块不会生成对应的网桥地址表,即手机1接入三地址路由器时,不会生成对应的网桥地址表。
手机1的实际接入点为三地址路由器,而不是主网关,因此主网关无法收到手机1接入三地址路由器时的MAC消息;
管理模块获取到配置协议消息,所述配置协议消息中携带MAC地址a1b1c1d1和IP地址192.168.1.11,其中,配置协议消息中携带MAC地址为物理地址,然后根据配置协议消息中的MAC地址a1b1c1d1匹配网桥地址表中的MAC地址(即判断在网桥地址表中是否含有与配置协议消息中的MAC地址相同的MAC地址对应的行记录),若根据所述配置协议消息的MAC地址a1b1c1d1在网桥地址表中匹配到相同的MAC地址,(表示该配置协议消息是由四地址路由器或者四地址路由器的下挂设备发出的),若根据所述配置协议消息的MAC地址a1b1c1d1在网桥地址表中未匹配到相同的MAC地址,即根据配置协议消息中的MAC地址a1b1c1d1无法从网桥地址表中匹配到有相同MAC地址的行记录(此时表示该配置协议消息是由三地址路由器或者三地址路由器的下挂设备发出的),由于本实施例假设的是手机1接入三地址路由器(即手机1作为三地址路由器得到下挂设备),因此根据所述配置协议消息的MAC地址a1b1c1d1在网桥地址表中是无法匹配到相同的MAC地址的。此时根据所述配置协议消息的IP地址192.168.1.11判断当前的网络地址表中是否含有与所述配置协议消息的IP地址192.168.1.11相同的行记录,由于本实施例是假设管理模块先收到配置协议消息,因此管理模块还未收到手机1发出的地址解析协议消息,那么根据所述配置协议消息的IP地址192.168.1.11在网络地址表中是无法找到相同的IP地址的,此时将所述配置协议消息的MAC地址a1b1c1d1和IP地址192.168.1.11存入当前的网络地址表的行记录2中,等待地址解析协议消息发起匹配并更新网络地址表。
管理模块获取到地址解析协议消息,所述地址解析协议消息中携带MAC地 址1A1B1C1D和IP地址192.168.1.11,根据地址解析协议消息中的IP地址判断当前的网络地址表中是否含有与所述地址解析协议消息的IP地址相同的行记录;由于管理模块已经收到手机1发出的配置协议消息,且已将配置协议消息的MAC地址a1b1c1d1和IP地址192.168.1.11存入网络地址表的行记录2中,因此可根据地址解析协议消息中的IP地址192.168.1.11在网络地址表中匹配到相同的IP地址,那么此时判断所述地址解析协议消息的MAC地址1A1B1C1D与所述网络地址表中与地址解析协议消息的IP地址相同的行记录对应的MAC地址是否相同,由于根据地址解析协议消息中的IP地址192.168.1.11在网络地址表中匹配到相同的IP地址的行记录为“a1b1c1d1,192.168.1.1”,可知,匹配到的行记录对应的MAC地址为a1b1c1d1,其与地址解析协议消息的MAC地址1A1B1C1D不同,则将地址解析协议消息中的MAC地址1A1B1C1D更新至在网络地址表中匹配到的不同的MAC地址对应的行记录“a1b1c1d1,192.168.1.1”中,即更新至网络地址表的行记录2中(若根据地址解析协议消息中的IP地址192.168.1.11在网络地址表中匹配到相同的IP地址的行记录,且地址解析协议消息的MAC地址与所述网络地址表中与地址解析协议消息的IP地址相同的行记录对应的MAC地址是不相同,那么说明发出该地址解析协议消息的为三地址路由器或者三地址路由器的下挂设备发出的,而非四地址路由器或者四地址路由器的下挂设备发出的,且地址解析协议消息的MAC地址与所述网络地址表中与地址解析协议消息的IP地址相同的行记录对应的MAC地址为物理地址,即a1b1c1d1为物理地址)。将地址解析协议消息中的MAC地址1A1B1C1D更新至在网络地址表中匹配到的不同的MAC地址对应的行记录“a1b1c1d1,192.168.1.11”之后,网络地址表中便含有1A1B1C1D、a1b1c1d1和192.168.1.11。
最后使用地址解析协议消息的MAC地址在MAC表中匹配相同的MAC地址,若匹配到,则可获取MAC表中匹配到的相同的MAC地址对应的接入端口,以便对设备进行标识。即根据地址解析协议消息的MAC地址1A1B1C1D在MAC表中匹配相同的MAC地址,由于三地址路由器接入主网关时生成了含有“1A1B1C1D,PORT1”这样一条行记录的MAC表,因此可根据地址解析协议消息的MAC地址1A1B1C1D在MAC表中匹配相同的MAC地址对应的行记录“1A1B1C1D,PORT1”,匹配到之后取出“1A1B1C1D,PORT1”这一条行记录中的接入端口PORT1,将1A1B1C1D、a1b1c1d1,192.168.1.11和PORT1放入设备列表的行记录2中,根据a1b1c1d1、192.168.1.11和PORT1作为设备标识信息。当管理模块收到手机1接入三地址路由器时的配置协议消息和地址解析协议消息后:
MAC消息中的行记录不变,依旧含有行记录“1A1B1C1D,PORT1”;
网络地址表含有行记录“1A1B1C1D,1a1b1c1d,192.168.1.1”和“1A1B1C1D,a1b1c1d1,192.168.1.11”,即分别为网络地址表的行记录1和行记录2。
设备列表中含有行记录“1A1B1C1D,1a1b1c1d,192.168.1.1,PORT1”和“1A1B1C1D,a1b1c1d1,192.168.1.11和PORT1”,即分别为设备列表的行记录1和行记录2。
(1-3)如图11所示,将手机2接入三地址路由器:
将手机2接入三地址路由器时的方法过程可参考手机1接入三地址路由器时的方法过程,当手机2接入三地址路由器后:
MAC消息中的行记录不变,依旧含有行记录“1A1B1C1D,PORT1”;
网络地址表含有行记录“1A1B1C1D,1a1b1c1d,192.168.1.1”、“1A1B1C1D,a1b1c1d1,192.168.1.11”和“1A1B1C1D,a2b2c2d2,192.168.1.12”,即分别为网络地址表中的行记录1、行记录2和行记录3。
设备列表中含有行记录“1A1B1C1D,1a1b1c1d,192.168.1.1,PORT1”、“1A1B1C1D,a1b1c1d1,192.168.1.11和PORT1”和“1A1B1C1D,a2b2c2d2,192.168.1.12,PORT1”,即分别为设备列表的行记录1、行记录2和行记录3。
如图15所示,将四地址路由器、手机3和手机4三台设备依次接入主网关构成四地址组网模式,根据接收到的消息对三台设备进行标识。
(2-1)如图12所示,将四地址路由器接入主网关:
四地址路由器或者四地址路由器的下挂设备接入主网关时,驱动模块便会生成包含四路由器或者四路由器的下挂设备的物理地址和接入端口的网桥地址表,假设四地址路由器的物理地址和接入端口分别为2a2b2c2d和PORT2,那么当四地址路由器接入主网关时,便会在网桥地址表的行记录1中生成行记录“2a2b2c2d,PORT2”。
管理模块获取到配置协议消息,所述配置协议消息中携带MAC地址2a2b2c2d和IP地址192.168.1.2,其中,配置协议消息中携带MAC地址为物理地址,然后根据配置协议消息中的MAC地址2a2b2c2d匹配网桥地址表中的MAC地址(即判断在网桥地址表中是否含有与配置协议消息中的MAC地址相同的MAC地址对应的行记录),若根据所述配置协议消息的MAC地址2a2b2c2d在网桥地址表中匹配到相同的MAC地址(表示该配置协议消息是由四地址路由器或者四地址路由器的下挂设备发出的),若根据所述配置协议消息的MAC地址2a2b2c2d在网桥地址表中未匹配到相同的MAC地址(表示该配置协议消息是由三地址路由器或者三地址路由器的下挂设备发出的),由于本实施例假设接入的是四地址路由器,因此当四地址路由器接入主网关时,便会在网桥地址表中生成行记录“2a2b2c2d,PORT2”,则根据所述配置协议消息的MAC地址2a2b2c2d在网桥地址表中可匹配到相同的MAC地址对应的行记录“2a2b2c2d,PORT2”(即在网桥地址表的行记录1中匹配到),获取所述匹配到的网桥地址表中的MAC地址对应的行记录中的接入端口PORT2,将2a2b2c2d、192.168.1.2和PORT2放入设备列表的行记录1中,根据2a2b2c2d、192.168.1.2和PORT2 作为设备的标识信息。
当四地址路由器接入主网关后:网桥地址表中含有行记录“2a2b2c2d,PORT2”,对应网桥地址表中的行记录1;
设备列表中含行记录“2a2b2c2d,192.168.1.2,PORT2”,对应设备列表的行记录1。
(2-2)如图13所示,将手机3接入四地址路由器:
手机3接入系统时,驱动模块便会生成包含手机3的物理地址和接入端口的网桥地址表,假设手机3物理地址和接入端口分别为a3b3c3d3和PORT2,那么当手机3接入主网关时,便会在网桥地址表的行记录2中生成行记录“a3b3c3d3,PORT2”
手机3的实际接入点为四地址路由器,而不是主网关,因此主网关无法收到手机3接入四地址路由器时的MAC消息;
管理模块获取到配置协议消息,所述配置协议消息中携带MAC地址a3b3c3d3和IP地址192.168.1.21,其中,配置协议消息中携带MAC地址为物理地址,然后根据配置协议消息中的MAC地址a3b3c3d3匹配网桥地址表中的MAC地址(即判断在网桥地址表中是否含有与配置协议消息中的MAC地址相同的MAC地址对应的行记录),若根据所述配置协议消息的MAC地址a3b3c3d3在网桥地址表中匹配到相同的MAC地址(表示该配置协议消息是由四地址路由器或者四地址路由器的下挂设备发出的),若根据所述配置协议消息的MAC地址a3b3c3d3在网桥地址表中未匹配到相同的MAC地址(表示该配置协议消息是由三地址路由器或者三地址路由器的下挂设备发出的),由于本实施例假设手机3接入的是四地址路由器,因此当手机3接入四地址路由器时,便会在网桥地址表中生成行记录“a3b3c3d3,PORT2”,则根据所述配置协议消息的MAC地址a3b3c3d3在网桥地址表的行记录2匹配到相同的MAC地址对应的行记录“a3b3c3d3,PORT2”,获取所述匹配到的网桥地址表中的MAC地址对应的行记录中的接入端口PORT2,将a3b3c3d3、192.168.1.21和PORT2放入设备列表,根据2a2b2c2d、192.168.1.2和PORT2作为设备的标识信息。
当手机3接入四地址路由器后:网桥地址表中含有“2a2b2c2d,PORT2”和“a3b3c3d3,PORT2”,分别对应网桥地址表中的行记录1和行记录2;
设备列表中含行记录“2a2b2c2d,192.168.1.2,PORT2”和“a3b3c3d3,192.168.1.21,PORT2”,分别对应设备列表的行记录1和行记录2。
(2-3)如图14所示,将手机4接入四地址路由器:
将手机4接入四地址路由器时的方法过程可参考手机3接入四地址路由器时的方法过程,当手机4接入四地址路由器后:网桥地址表中含有“2a2b2c2d,PORT2”、“a3b3c3d3,PORT2”和“a4b4c4d4,PORT2”,分别对应网桥地址表中的行记录1、行记录2和行记录3;
设备列表中含行记录“2a2b2c2d,192.168.1.2,PORT2”和“a3b3c3d3,192.168.1.21,PORT2”和“a4b4c4d4,192.168.1.22,PORT2”,分别对应设备列表的表1、行记录2和行记录3。
根据设备列表可对设备进行标识。
