Some time ago, I made vro networking. Because of the use of the openwrt operating system, it was easy to do so, but many detailed principles were ignored. So let's talk about the differences between WAN ports and LAN ports and how they work.
First, Baidu:
Anyone familiar with the network knows that Wan is written in the first letter of the English wide area network, that is,
This is a dual-WAN port router evaluation. I have made a detailed introduction to what you are concerned about, from the appearance design of the interface to various internal performance indicators, they all make us feel bright. In our report, we can also learn its settings.

With the popularity of BYOD, mobile networks make WAN more complex. This article introduces the functions and management methods of mobile networks on the edge of WAN.
In the past, WAN boundary definition was very simple in loose traditional enterprises. Now, an uncertain location of a mobile device makes the WAN bound
Chapter 4 Basic Principles of WanWan and OSI reference model Wan mainly correspond to the physical layer and data link layer of the OSI reference model, that is, the network access layer of the TCP/IP model. The WAN physical layer specifies the physical and electrical properties, mechanical properties, and connection standards of devices, lines, and interfaces that provide services to the
With the rapid development of global routing technology, dual-WAN port broadband routers are also widely used in enterprises. The following describes how to buy dual-WAN port broadband routers, when purchasing a dual-WAN port Broadband Router, you also need to consider whether its internal processing mechanism supports the identity binding technology. This is mai
In Linux, there is an out of memory killer feature, which will jump out when the system memory is used up and selectively kill some processes to release some memory. I believe that the majority of migrant workers who are engaged in programming on the Linux server have more or less met each other ). A typical scenario is that one day the machine suddenly fails to be pinged, but ssh cannot be connected. The reason is that the sshd process was killed by

How the ICMP ping test works
Ping is a dedicated IP network tool that Ping sends an ICMP echo request message to the destination and reports whether it receives the expected ICMP echo response. Each operating system has the Ping tool installed, and any common enterprise platform, like Windows or Mac OS X, can find it.
You can run the Ping delay test on any network device. The target host can be any other device, such as a computer, a router, or any device with an IP address on the network. In

At present, the router industry is developing at a high speed. At this stage, the routing technology is very mature. Next we will mainly explain how to use dual-WAN Port Routers to achieve communication between China Netcom and China Telecom. Currently, China's ISP service providers mainly include China Telecom and China Netcom. The bandwidth between China Telecom and China Netcom is low, leading to many problems. This problem has an impact on the Inf
to ensure the proper protocol is used, the router must be configured with the appropriate layer 2nd encapsulation.The choice of the protocol needs to be determined based on the WAN technology and communication equipment used. The router encapsulates the packet in two-layer frame format and then transmits it to the WAN link. Although there are several different WAN
