With the further construction of China's information network, the further improvement of network quality, high-speed, high-performance Ethernet switch will become the mainstream of network product development. switch is an essential equipment for the network of large and medium sized enterprises, it plays a very important role in network construction, it can increase network capacity and improve network s

This digest is from http://www.pconline.com.cn/pcjob/ittest/network/0312/258919.htmlOther literature http://www.jztop.com/s/jiaohjjs/ Comparison of three-layer switch and router In order to meet the challenge of deepening the network application, the network has been developing rapidly in both scale and speed, the speed of LAN has been improved from the initial 10mbit/s to the 100mbit/s, and the Gigabit Ethernet technology has been widely used at pres

With the development of the times and the development of science and technology, the layer-4 switch technology is also widely used for everyone. It can take corresponding actions based on the observed information, implement the key functions of bandwidth allocation, fault diagnosis, and access control over TCP/IP application data streams. With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and

In order to improve the LAN operation and maintenance efficiency, we need to accumulate various switch troubleshooting experience at ordinary times so that the switch can be quickly rectified in case of a fault, this article has contributed several vswitch troubleshooting skills to my friends. I hope these content will help you! 1. Solve the trouble of resetting VLAN When managing and maintaining a LAN, if

Reasonable configuration solves the problem of Switch network loop, in the way of judging switch network loop, this paper makes a preliminary analysis of switch network loop problem from log information and enabled state, then rationally configures the switch and finally solves the

After the switch system is restarted successfully and the VRP platform software has been updated, it is necessary to carefully and carefully maintain the updated software, next, let's give some comments and opinions on the switch system. As a core network terminal in a LAN, maintaining the switch system becomes very important. In order to make the LAN work more s

Tab tab switch effect JavaScript Summary It is very common to switch tabs on current web pages. HoweverTab SwitchBut there are a lot of things to be aware of, how to use the least code, the most flexible implementation. JavaScript code implemented by 37 tabs is collected here. Non-Original Source Network: original address: http://paranimage.com/37/ 1) EasyTabs 1.2 With autochange-you can set the tab menu in

Cocos2d-x trip _ 39] simulate a switch in LUA This is actually not difficult, but a friend told me that he encountered the question "Please use lua to simulate Switch" during the interview ...... I think of sharing my previous articles ...... The code is simple: _ G. switch = _ G. switch or {} _ G.

Slow network speed is a common type of switch failure. We need to carefully analyze the error records of the faulty switch so that we can fundamentally solve the problem and avoid repeated errors later. When the network scale is relatively large, the "load" of switches that shoulder network data forwarding, content filtering, and management control tasks will be very heavy. In addition, like a person's heal

As a network operations engineer, if the management of the routing, switching equipment more, then you will also encounter the same problem with me: The device configuration is often adjusted, especially the access layer switch, in case you forget to save the configuration, and the next day a switch power-down restart, you have forgotten the previous configuration, Causes the network restore configuration t

Hub, switch, router, working principle 1. A switch is also called a switch hub. It regenerates information and forwards it to a specified port after internal processing. It has the ability to automatically address and exchange information, the switch sends each information packet independently from the source port to t

Switch Equipment is still quite common, So I studied the status error of Switch Equipment and shared it with you here. I hope it will be useful to you. Without any clue, I had to go to the Central Data Center of the organization, open the cabinet, and want to see if any switch in the LAN is not running properly. The status of the signal lights in the control pane

The layer-4 switch actually adds the ability to identify the layer-4 protocol port in the layer-3 Switch, meeting more user needs and improving the performance. In recent years, with the popularization of G, 1g, or even 10g LAN. The wide application of Broadband LAN and even Bandwidth WAN drives the continuous development of switch technology. In enterprise appli

Layer-4 switches are quite common. So I studied the layer-4 switch technology and application. Here I will share it with you and hope it will be useful to you. With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used. Whether it is Intranet, exclusive, or residential intelligent networks, it is increasingly expanding to massive amounts of informa

With the development of China's exchange industry and the promotion of updates and upgrades of the soft switch technology, we mainly analyze the development relationship between the soft switch technology and the Next Generation Network. Over the past few years, with the rapid popularization and maturity of domestic IP phone technology and successful market operation practices, people have been paying more

Of the six Ethernet switches we tested, the Edimax es-5800r and LeaPComm6004 switches are not managed switches, Accton ES4508, and the Thinker3800 switches of the creators are all network-management switches, 3Com 4900 is to support the three-layer and four-layer switch, Shenzhou digital D-link DGS3308TG is a three-tier switch. Performance is the brunt The 6 products include all copper ports, all fiber po

A layer-4 switch is a vswitch product developed through the layer-4 switch technology. A layer-4 switch is not so much a network device as a network management system. In recent years, with the popularization of Mbit/s, Gbit/s, and even Mbit/s, the wide application of Broadband LAN and even Bandwidth WAN has driven the continuous development of

With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used. Whether it is Intranet, exclusive, or residential intelligent networks, it is increasingly expanding to massive amounts of information, it is forcing people to transmit audio, video, data and other information in the network system more and more demanding. With the rapid development of Internet, the use of e-commerce, e-government, e
