A, the classification of routers
According to the performance grade: the back plate exchange capacity of more than 40Gbps routers called high-end routers, less than 25Gbps called low-grade routers.
By structure: Routers can be divided into modular structure and non modular structure.
The modular scene structure can flexibly configure the router to meet the increasing business requirements of the enterprise, and the modularization can only provide a
In the days when wired networks are everywhere, the "figure" of the wireless LAN is approaching us, and there is a great way to work together with wired networks. Considering that the current wireless LAN networks are all made up of wireless routers, the efficient access to the wireless LAN is closely related to the status of the wireless router. Unfortunately, after a long period of work, the Wireless Router
Why bridge the wireless router? The benefits of wireless bridging, bridging can be two different physical locations, inconvenient wiring of users to connect to the same LAN. Wireless bridging can also play a role in signal amplification. We can bridge multiple wireless routers together to achieve the signal coverage. At least one router supports the WDS feature, but the two routers don't have to be the same
In the days when wired network is ubiquitous, the "figure" of WLAN is moving closer and nearer to us, which is very much in step with the wired network. Considering the current wireless LAN is through the wireless router to network, wireless LAN can be efficient Internet and wireless router status closely related; Unfortunately, wireless routers in the long hours, often appear a variety of "strike" phenomen
inaccessible. Every 30 seconds, the distance vector routing protocol sends the entire route selection table to the adjacent site to update the route selection table of the adjacent site. In this way, it can collect a list of networks from other sites (directly connected or connected in other ways) for route selection. Distance Vector Routing uses the number of hops as the metric value to calculate the number of routers that need to pass to the destination.
For example, r I p uses the B e l m a
For wireless networks, we always focus on the routing configuration. So here we will summarize the detailed description of the wireless router configuration. Before configuring a wireless router to configure a wireless router, you must connect C to the wireless router with a network cable. the other end of the network

For everyone in the process of using the router encountered problems, small series I think it is necessary to popularize some of the router's small knowledge, I believe that as long as you carefully read, you will suddenly see the internet is no longer difficult!!
One, WAN Port no connection
Two, the WAN Port has the connection, but the connection failed.
Third, broadband normal, you can ping, but unable to open the Web page

How do I set up a wireless router? will be discussed in this section, the main of this series of courses the purpose is to popularize the basic knowledge of wireless router, introduce the basic function of no line, show more uses of wireless router. There is no inscrutable technology, no jerky nouns, no messy settings, just telling you How to set up a wireless
Router is the bridge of computer network, is the core device of connecting IP network. It can not only connect different networks, but also choose the path of data transmission, and can block illegal access. Routers are data packet forwarding devices that work in the third layer of the OSI Reference Model-the network layer, and routers implement network interconnection by forwarding packets. For beginners, routers are not easy to configure. This paper
This article describes the basic working principles of routers in TCP/IP networks, introduces several functions of IP routers, and provides Static Routing and dynamic routing protocols, as well as the concept of the internal gateway protocol and the external gateway protocol, and briefly introduces the most common RIP, OSPF, BGP and BGP-4 routing protocols, then, it describes the design objectives and types of routing algorithms, and focuses on the link state method and distance vector method. A
First, Introduction HSRP (hot Standby Router Protocol Thermal Backup Router protocol) is a proprietary protocol of Cisco. HSRP makes up a "hot backup group" of multiple routers, forming a virtual router. Only one router in this group is active (active), and it forwards the packets, and if the active
At present, China's wireless routers are developing rapidly, and there are also many problems. The following describes the problems that wireless routers often encounter during the connection process and gives you a detailed analysis. With the popularity of wireless networks, wireless routers gradually enter our lives. However, if you purchase a wireless router, in addition, you must also use the original wired wireless
The communications department allows each broadband user to use two computers to share the Internet, and the user needs to install a broadband router. So, what kind of router should be purchased more appropriate?
Today's broadband router many features for the average home user is really very practical, can improve the performance of many Web applications. The fo
At present, PE routers are widely used. They are one type of VPN routers. So I have studied the explanations and principles of PE routers and will share them with you here, I hope it will be useful to you. VPNVirtual Private Network (VPNVirtual Private Network) is a virtual Private Network based on public networks. It uses tunneling, encryption, and other technologies to provide users with a sense of direct connection to the Private LAN.

This paper introduces the method of setting up the Wired Bridge of the Tp-link router, and the router cable bridge is strictly called: two (multiple) routers in series Internet. Mainly applicable to such a network environment: There are a, B two Tp-link routers, a connect moden (cat) Internet, and then connect A and B with a network cable, to achieve the B router
