About the knowledge of wireless routers Some technical analysis of routers

When it comes to wireless routers, I think friends who have more than two computers at home should know that it is a very useful thing. It meets the unlimited Internet needs of our mobile phones, notebooks, tablets and other devices. However, many people are not very familiar with wireless routers while demanding. It doesn't matter if you don't understand, let's study this article together. Wireless network router knowledge: Friends who use wireless Internet access must be familiar with routers. With a router, we can play CS, dota, etc. in a dormitory. So what is the router? What role does he have? What are the related technologies of routers? Today, Xiaobian is like a simple introduction to everyone. Routers are one of the most important devices on the Internet. It is the tens of thousands of routers all over the world that form the "bridge" of the Internet, a huge information network that runs around us day and night. The core communication mechanism of the Internet is a data transmission model called "store and forward". Under this communication mechanism, all data flowing on the network is transmitted, transmitted and received in the form of a packet. In addition, we briefly introduce some router technologies: STUN technology: serial tunnel (serialtunnel) technology. The technology is to send the SNA software package from the serial port of FEP (3745/6) to the router, package it into IP data packet through the router, and then transmit it in the network formed by the router, to the target router, and then through the router. The SDLC packet that the packet is restored to SNA is sent to the SDLC interface device. CIP technology: CIP is the Channel Interface Processor (ChannelInterfaceProcessor). It is built into a card device that can be easily installed in the CISCO7000 series of routers. CIP provides multi-protocol Internet access for IBM large machines by directly connecting to the channel of IBM. Provides TCP/IP, SNA, and APPN traffic for large machines, thus eliminating the need for intermediate devices such as the 3172 Interconnect Controller and IBM 3745/6FEP. DLSW Technology: is an international standard technology that can be used to pass SNA packages via IP. After the mode is packaged, it is transmitted by the IP network to any router node on the IP network, and then transmitted to the SDLC interface device via the serial port of the router or transmitted to the LLC2 link layer protocol via the Ethernet interface (or TOKENRING) interface device to transmit the SNA data. SNA node of the packet (such as RS6000). An E1 interface of MIP: 30 sub-channels of 64Kbps can be provided, and the channels can also be combined into larger sub-channels of N×64K, which is enough to meet the connection with the local market for a long time. Bandwidth requirements.
