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...

工业级路由器路径属性分为哪4类?

文章目录 : 产品文章

工业路由器发送关于目标网络的BGP更新消息,更新的度量值被称为路径属性。属性可以是公认的或可选的、强制的或自由决定的、传递的或非传递的。属性也可以是部分的。并非组织的和有组合都是合法的,工业级路由器路径属性分为4类:4g路由器

1——公认强制的

2 ——公认自由决定的

3 ——可选传递的

4 ——可选非传递的

只有可选传递属性可被标记为部分的

公认属性【全网通路由器

是公认所有BGP实现都必须能够识别的属性。这早些属性被传递给BGP邻居。

公认强制属性必须出现在工业无线路由器路由描述中,公认自由决定属性可以不出现在全网通工业路由器路由描述中

可选属性

非公认属性被称为可选的,可选属性可以是传递的或非传递的

可选属性不要求所有的BGP实现都支持

对于不支持的可选传递属性,工业LTE路由器将其原封不动地传递给其他BGP工业级无线路由器,在这种情况下,属性被标记为部分的。

对于可选非传递属性,工业级LTE路由器必须将其删除,而不将其传递给其他BGP工业4g路由器

BGP定义属性

公认强制属性

公认自由决定

可选传递属性

可选非传递属性

BGP每条更新消息都有一个长度可变的路径属性序列<属性类型,属性长度,属性值>,如果第1比特是0,则属于是公认属性,如果工业级4G路由器是1,则该属性是任选属性,如果第2比特是0,则该属性是不可传递的,如果它是1,则属性是可传递的,公认属性总是可传递的,属性标志域中的第3个比特指示任选可传递属性中的工业全网通路由器信息是部分的(值为1)还是完整的(值为0),第4个比特确定该属性长度是1字还是2字节,标志域其他4个比特总为0.全网通工业级路由器属性类型代码字节含有属性代码。全网通4g路由器
