Details: Home Network: advanced functions of home routers. From the following article, we can see details about the specific running environment and its size. If you are interested, try it. After successfully logging on to the vro Management page, there are several menus on the left-side menu bar: running status, setting wizard, network parameters, DHCP server, forwarding rules, security settings, routing functions, and system tools. You can set a pro
flowing into the protected network. A security router is usually a network security device that integrates the conventional routing and network security functions. It is also a router, mainly responsible for Routing Switching tasks in the network, but more security features are available, including built-in firewall modules. In general, high-performance security routers have the following main functions:
1) Network Interconnection
The router is a net
The technologies and applications of Multi-Wan Port Routers are insufficient for NAT as network application requirements increase. In particular, users have urgent requirements on network security and other functions to ensure the safe and smooth operation of the network. The design of broadband routers is increasingly complicated, including FIREWALL, DMZ, and virtual servers, broadband
wireless routers are the network of this mode.There is an essential difference between a wireless relay router and a common network of home wireless routers. Ordinary wireless routers generally walk on the ADSL PPPoE, which is the wired network. The downside is to share the Internet of wired networks with other devices through wireless hotspots. Wireless relay i

Routing principlewhen one host in an IP subnet sends an IP packet to another host on the same IP subnet, it will send the IP packet directly to the network, and the other party can receive it.
Security routers are widely used in enterprises. It does not matter if many people do not know how small and medium-sized enterprises buy security routers. After reading this article, you will certainly have a lot of GAINS. I hope this article will teach you more. A security router is usually a network security device that integrates the conventional routing and network security functions. It is also a secu
As the most common broadband access service, ADSL is widely used. For home users, the ADSL access method is the best choice. It is highly cost-effective in terms of bandwidth and price. However, for small and medium-sized enterprises that have Internet cafes, due to the large number of internal computers, the use of ADSL access seems to be somewhat slow, so such as DDN, optical fiber, ATM and other leased line access are popular in these places. However, many small and medium-sized enterprises a
At present, Cisco routers have a very high market demand. Here we mainly introduce the use of OSPF to solve the defects of the RIP route information protocol, including the OSPF Authentication Method. OSPF is also an open version of The Link Status Protocol.
In practice, OSPF is often used in some large and hybrid networks. In the previous article, I talked about the defects of the RIP Protocol. The reason why network experts develop the OSPF protocol
Currently, Internet-based applications of Internet cafe users have expanded from simple web browsing to more extensive fields such as QQ chat, VOD on demand, online games, education and training, and IP phones, the increasing number of these applications puts forward higher and higher requirements on the speed and stability of the network. Therefore, the performance requirements for routers in Internet cafes are also increasing accordingly: first, mor
More and more Wan solutions are now using Ethernet overSDH. On the surface, L3 switches and traditional routers can meet the needs of Wan interconnection. Therefore, many partners and customers have this question, what is the difference between the two in the wide area network connection? The following are some of my opinions for your reference.What is the difference between using a Cisco L3 switch and using a router as a WAN connection?First, the net
Wireless routers are unable to access the reason and the solution, the use of wireless routers more and more people, there will be more and more problems.
Along with the development of network technology, the use of wireless network is more and more common, the problem that wireless router can't access the Internet is more and more often encountered. Considering the current wireless LAN is through the wire
With the wide application of enterprise routers, the technology is also more advanced. Here we mainly introduce you to several highly cost-effective enterprise routers. This year is the Year of the Ox. As the saying goes, in the Year of the Ox, everyone hopes that the financial crisis will quickly pass, the stock market will recover as soon as possible, and their families will be healthy. What cool, cool, b
A few days ago, security researchers discovered a botnet worm called psyb0t, which can attack DSL modems and routers. This worm can search for and exploit specific devices with open ports. The attacked device also has a weak password. Once a worm enters a vro, it can do whatever it wants, block the port, leak sensitive information, and attack other networks.
In this article, I will analyze the router types that are vulnerable to this specific worm att

Multi-line bundling technology not only helps users greatly increase bandwidth and network speed, but also enhances system stability and facilitates network operation and maintenance. Currently, most VPN Router systems use a line at the headquarters to handle data volumes from several or even dozens of branches and mobile users. Especially in asymmetric lines similar to ADSL, the uplink bandwidth is originally narrow, resulting in overwhelmed data volume at th
Users who use wireless routers have encountered frequent disconnection problems. Here we mainly explain the solutions and causes of this problem. In recent Internet forums, many netizens have reported that home routers may experience a 24-hour disconnection. In fact, this may be a means for operators to prevent account theft, users do not have to worry too much. However, in addition to the quality problems
Speaking of the performance of the vro, I would like to give you a brief introduction to what is a vro and what a vro is used!
A router is a network device that connects multiple networks or CIDR blocks. It can translate data between different networks or CIDR blocks ", so that they can "read" each other's data to form a larger network.
Vro has two typical functions: Data tunnel and control. The data channel functions include forwarding decision, backplane forwarding, and output link scheduling,

Holding this view will certainly question the availability of the router. But in fact, whether in reality,
rate is not equal, then the queue will eventually disappear, and if it lasts less than the queue input rate, the queue will grow longer, which is common sense, but these are the basis for in-depth analysis.3. Conclusion we can see from the analysis, the increase in service resources a little bit, do not need to increase too much, we have to achieve the effect is, the deviation of an angle, so that the service output curve and queue input curve final intersection can be:Reality: The analysis and

One is to update the route information, publish some or all of the route information, and the router learns route information from each other to master the topology of the whole network, this type of routing protocol is called the distance vector routing protocol. The other is that the router broadcasts its own link status informatio
