Industrial-grade 4G router TCP/IP network architecture 1. Layering of TCP/IP network system   TCP/IP (TransmissionControlProtocol/InternetProtocol), transmission control protocol/Internet protocol. It was developed by the defense advanced research projects agency in the 1970s, and was later integrated into UNIX and popularized. It emerged in the 1980s as the Internet's...

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4G路由器区分标准:根据区域号来区分

文章目录 : 产品文章

  工业4G路由器区分标准:根据区域号来区分。0为骨干区域,其余的为标准区域。

  所有的工业4G路由器标准区域必须和骨干区域直接相连。所以设计OSPF的时候。每个区域必须有一个工业LTE路由器和骨干区域连接,这个路由就叫ABR(areaborder)区域边界工业路由器,这个台工业3G路由器属于不同的区域,其中有一个与是骨干区域

  OSPF分区域管理有什么好处:

  1、节约资源。指的是具体的设备。工业全网通路由器占用机器内存,计算算法的时候要占用CPU,发送更新时候要占用带宽

  2、加快收敛,因为如果一个区域内工业级3G路由器过多,更新的速率太慢
