There are still many things worth learning about in operation-level routers. Here we mainly introduce the features and products of operation-level routers. IP networks are hierarchical and can be roughly divided into core backbone) layer and edge layer, and corresponding operation-level routers can also be divided into core backbone)

Throughout the Internet research field, router technology has always been at the core position, and its development history and direction have become a microcosm of Internet research. In the Internet, routers, as the main node devices, are the key devices for connecting networks and the hubs of interconnected networks. The Hub function is to establish connections between different networks. The vro system forms the main context of the TCP/IP-based Int

Speaking of the performance of routers, may I first give you a brief introduction of what is a router, what routers are used to do! A router is a network device that connects multiple networks or segments to "translate" data information between different networks or segments so that they can "read" each other's data to form a larger network. Routers have two ty

Edge router positioning is the user from the LAN to the WAN, in the LAN and WAN technology is still very different today, the edge routers shoulder a variety of tasks, simply to meet the needs of users of a variety of business, from simple network to complex multimedia business and VPN business. This requires the edge of the router in hardware and software must have a perfect implementation. The equipment providers have therefore launched a fierce com

present, wireless routers in the indoor launch power generally does not exceed 20dBm. The higher the transmitting power of the wireless router, the higher the signal strength, but more than the specified range will cause large electromagnetic radiation and interference. antenna gain: the greater the gain, the stronger the signal strength, at present, most of our routers antenna gain 3dBi.

Firewall has become a key component in the construction of enterprise network. But there are a lot of users, that the network has a router, you can achieve some simple packet filtering function, so why use a firewall? The following is a comparison of the security aspects of the Neteye firewall and the most representative Cisco routers in the industry to explain why there are routers in the user network and

This article describes in detail how low-end and high-end routers think about network security, as well as the basic principles of routers. I believe this article will help you. Low-end routers and high-end routers are similar in usage. Why is the price so far different ?" In fact, this question is very good, and many

Backbone routers have a lot to learn from the place, here we mainly introduce the backbone of the router function and performance. It is estimated that the backbone routers will account for 15 billion USD, the LAN Converter will account for 10 billion USD, and the traffic management exchanger will grow to 4 billion dollars. If the survey report is accurate enough, then it means that the backbone

Routers, generally dlink or tplink, are users themselves in their own home network, a number of computers share an external network cable line tool. switch, mainly only to increase the number of ports, the general router only provides 4 intranet ports, so that there are

One of the functions of a router is to connect to different networks, and the other is to select the route of information transmission. Choose smooth shortcut, can greatly improve communication speed, reduce network system communication load, save network system resources, improve network system unblocked rate, so that the network system to play a greater benefit. From the point of view of filtering network traffic, the function of router is very similar to that of switch and Network Bridge. Ho

For many Internet cafe administrators, it is very important to correctly buy broadband routers for Internet cafes. With the rich Internet resources, many friends want to obtain resources through the network and even perform various entertainment through the network, the Internet cafe industry has become more prosperous. Internet cafes are a multi-person and complex environment. The speed and stability of Internet access are critical. Therefore, many I

The modular router plays an important role in the development of the network. Today, I will explain the main advantages of the modular router. With the development of network technology and the expansion of network services, IP technology and broadband services have higher requirements on routers in terms of reliability, interface density, flexibility configuration, data packet forwarding speed, and multi-service. In today's networks, modular

Preface In the current enterprise network, most of the wired networks are affected by factors such as investment cost and transmission speed. Vro is an important bridge connecting local networks to external networks. It is an indispensable component in the network system and a cutting-edge entry in network security. It is very important to improve its performance. More and more functions of current vro devices are implemented in hardware mode. The improvement of CMOS integration technology enabl

In recent years, the development of the Internet has been very rapid and applications have become increasingly commercialized, making it difficult to predict the development of the number of online users. In addition, more and more users need high-speed access. According to relevant information, the slow speed of Internet access is the primary cause of complaints from many netizens. Therefore, it is increasingly important to improve network bandwidth, network service quality, and network managem

Routers play an important role in the internet cafe network environment, but also often encounter many problems. Here we mainly analyze how the Internet cafe routers solve frequent disconnection problems. 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 ph

Because of carrying a variety of services on IP network, it is very important for the operators to provide reliable business for the users, and to provide a stable and reliable operation network can make the network operators improve their competitiveness greatly. The reliability of the backbone routers in IP network plays an important role in particular. According to www.lightreading.com statistics, the backbone of the network in the core router fail

In the long run, bandwidth itself is always inadequate. The smart "devices" behind the network infrastructure--switches and routers--must assume the difficult task of being intelligent to keep pace with bandwidth requirements. Applications like video and digital x-rays always require a larger, smarter "pipeline", while VoIP applications require low latency and consistent delivery rates. In the middle of the 90, with the decline of traditional switches

Vro is the core device in the network. The hardware router is familiar to everyone, and the most typical is the Cisco Series router. Software routers are emerging products, such as Tiny Software's WinRoute Pro Software router and Vicomsoft's Internet Gateway Software router. Compared with software-based routers, some people think that Cisco products are purely hardware-based

With the development of the routing industry, the routing technology is constantly updated and the demand is increasing. Here we mainly introduce the development status of the Broadband Router, including the technical characteristics of the WAN port. The more mud, the more powerful the Buddha is, the more powerful the foundation is, so there is a saying: the emergence of multi-Wan broadband routers. The total bandwidth that users can obtain increases,

In today's world, the network is getting higher and higher, and communication methods between people and devices are changing with each passing day. Some of these communication types are well known, such as IP voice VoIP, digital images, multicast, on-demand video, peer-to-peer file sharing, and remote video conferencing. However, all these applications share a common feature, that is, the demand for network bandwidth can be described by the word "greedy. In the long run, the bandwidth itself is
