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...

The structure of 4G DTU The main function of DTU is to transmit data from remote devices back to the background center via wired/wireless. Different data transmission modes of DTU include all-network-connected DTU, GPRS DTU, WIFI DTU, CAN DTU and 4G DTU. Today, we will have a look at the structure and work flow of DTU.   To complete...

工业路由器UPDATE消息可以在BGP对等体间传输路由信息

文章目录 : 产品文章

  无线路由器:UPDATE消息可以在BGP对等体间传输路由信息。UPDATE中的信息可以用作构造不同自治系统的关系图。UPDATE消息可以用作向对等体通告单个有效工业FDD-LTE路由器,或者使多个撤销路由停止服务。UPDATE消息总是携带固定长度的BGP头。

  不可用路由长度:两字节无符号整数,指示撤销路由域的字节数长度。该值为零表示无撤销路由,此时不出现撤销路由字段。

  撤销路由:包含IP地址前缀列表的可变长字段,这些地址前缀表示全网工业级路由器将被撤销。这些地址前缀被表示成《长度,前缀》二元组。

  总路径属性长度:2字节无符号整数,代表路径属性列表字节数。

  路径属性:可变长的路径属性列表。每个路径属性被表示成一个三元组《属性类型,属性长度,属性值》。属性类型是一个2字节字段,包含属性标志字节和属性类型编码。

  网络层可达信息:可变长字段,包含IP地址前缀列表。网络层可达信息的长度没有显式定义,可以通过计算得到。工业LTE路由器每一个可达信息是一个长度与前缀的二元组。
