The advantage of using wireless data transmission module... Data transmission can be simply divided into two major types: wired (including the installation of optical cables, cables or leased telecommunication lines) and wireless (including the establishment of dedicated wireless data transmission system or the borrowing of CDPD, GSM, CDMA and other public network information platforms).     In...

工业路由器路由表维护及管理子模块的主要功能

文章目录 : 产品文章

  接收并处理从协议包处理模块发送来的路由信息。对于路由请求,查找路由表发送对应路由条目或者整个路由表。对于路由更新包,对接收到的全网通工业路由器条目和本地路由表条目进行比较,采用一定规则修改路由表。它主要包括两个子模块:

  决策过程:使用一个简单算法确认是否应该把接收到的路由信息增加到路由表条目中。

  积聚过程:对触发更新引入延迟发送定时,以便把延迟发送时内的各次触发更新合并成一条路由更新信息,提高更新报文的发送效率。

  路由表维护及管理子模块的主要功能是工业路由器信息库表项的查找,维护,删除,提供这些路由表操作的接口。

  路由表维护及管理模块共有三个信息库:【4g路由器

  收到的路由信息库:从请求和更新报文中获得的所有路由信息。

  本地路由信息库:对更新报文中获取的路由信息进行处理,形成的本地转发所用的信息库,即路由表。RIP模块启动时,它所知道的唯一网络是直接与之相连的网络,这些条目一般可从配置中得到。

  发送的路由信息库:对本地4G无线路由器信息库变更的路由条目进行路由积聚和其他处理而生成的路由信息库,该库直接用来向该路由器的邻居发送路由信息。
