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
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
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
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 the WinRoute Pro software router launched by tiny software and the Internet gateway software router launched by vicomsoft. Compared with a software-based Router, some people think that Cisco products are purely hardware-based routers
Over the years, the traditional router processing speed has been a lot of growth, but still not enough to keep up with the pace of strong applications. For example, they can now forward nearly 1 million packets per second. But considering a Gigabit Ethernet interface that can send 1,488,000 packets (PPS) per second and receive packets at 1,488,000pps speed, 2000 Gigabit Ethernet ports can easily overload the system. In contrast, multilayer switches/routers
SAN multi-protocol routers solve SAN access problems. a san Based on Fiber Channel can transmit data at a high speed of 200 Mb/s. An important difference between an optical fiber channel and other network protocols is its data transfer bandwidth utilization. In an Optical Fiber Channel architecture, the bandwidth utilization can easily reach more than 99%. This is incomparable to other existing network protocols. Fiber Channel can extend the SAN conne
When information needs to be transferred between two networks, the interconnection device of common routers is responsible for the transmission of data. The main work of the router is: The decision of the path and the forwarding of the packet (from the router an interface input, and then select the appropriate interface output); Maintenance path by the table.The way the router works is very concise, extracting the destination address from the receivin
Routers and switchesComputer networks are often connected by a number of different types of network interconnection. If several computer networks are physically connected and not able to communicate between them, then this "interconnection" is of little practical significance. So often when it comes to "interconnection", it has been hinted that these interconnected computers can communicate, that is to say, functionally and logically, these computer n
1, the question: CISCO3600 series routers currently support WAN interface card wic-2t and wic-2a/s? Answer: The CISCO3600 series routers support both the WIC-2T and wic-2a/s Wan interface cards in 12.007XK and above versions. However, it should be noted that only Fast Ethernet hybrid network modules can support these two kinds of WAN interface cards. The network modules that support both interface cards ar
Bridge (brouter) has the function of Network bridge and router. 5. In the network layer above the relay system, that is, gateways (Gateway). When a relay system is a forwarder, it is generally not called a network interconnect, because it is simply a network extension, and this is still a network. High-level gateways are less used because they are more complex. Therefore, the general discussion of network interconnection refers to the use of switches and
This article describes in detail how to configure multiple vrouters in the company and how to perform these operations in various situations? The following article provides detailed answers. With the development of China's routing industry, the application of multiple routers is also more extensive. Here we mainly analyze the specific configuration methods of multiple routers. Under what circumstances will
Understanding the features and architecture of Cisco routers the basic knowledge of Cisco routers is still important for a network engineer, which is the foundation of Cisco technology. This document describes the features and architecture of a Cisco Router Based on a Cisco router. Before learning about the various troubleshooting and diagnostic tools available for Cisco
discovery protocol allows routers to be discovered through IP hosts, but it is not widely used. This means that most hosts cannot quickly know whether the connection between the vro and the connected lan has failed, and it takes a long time for the IP host to detect the connection failure and exchange the replacement vro. Therefore, it is important for any device to improve the network efficiency. Using vro cluster technology can effectively solve so
called routing. This is also the origin of the router name (router, forwarder ). Bridge:1. A bridge, also known as a bridge, is a storage and forwarding device that connects two local networks. It can be used to connect a network system with the same or similar architecture. 2. Functions of the bridge: 1) the bridge only packs a small amount of received information frames without any modification.2) The bridge can use another protocol to forward information.3) The bridge has enough buffer space
Recently saw a lot of people asking about the switch, hub, router is what, function, what is the difference, the author on these questions to do some simple answers. First of all said Hub, that is, hubs. Its role can be simply understood to connect some machines to form a local area network. A switch (also known as a switched hub) works roughly the same as a hub. But there is a difference in performance: the way the hub uses shared bandwidth works, and the switch is the exclusive bandwidth. In
There are two routers in the home want to connect to use, or use someone else's network, want to pick up a router to use WiFi internet access, using a router cascade can connect two routers, convenient use of WiFi router. There are two ways to connect a two router: The first way: the route mode Cascade, the second level router and the superior router all have the routing function, two
With the development of the routing industry, its application is more extensive. Here we mainly analyze the knowledge about the backup router. Network Transmission of some key business data of some enterprises or organizations requires high reliability of network equipment and convenient maintenance. There are multiple backup technologies for Cisco routers. Here we will introduce the router's own backup technology and line backup technology. Generally
policy is called routing. This is also the origin of the router name (router, forwarder ). Bridge:1.

"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 friends who are not familiar with the product and technology will basically have similar questions-"Why is this router so expensive with the same functions, another one is so cheap. "Why is Cisco's vro so expensive? And TP-LINK is so cheap ?" "The two
