I believe many people know that layer-4 switches are commonly called Application switches in the industry. Here we will mainly introduce layer-4 switch technologies and functions. With the popularization of broadband and the deepening of various network applications, our local network is undertaking heavy business traffic. The amount of transmitted audio, video, data, and other information in the network system is full of bandwidth. We have to provide
With the advent of the Internet era, security issues have become an urgent issue. The existence of viruses, hackers, and various vulnerabilities makes security tasks extremely difficult in the Internet era.
Vswitches play an important role in the enterprise network, usually the core of the entire network. In the network era where hackers are intruding into the cloud and the virus is raging, the core switch also takes responsibility for network securit
Currently, the mainstream Gigabit backbone switches have high forwarding capabilities and smaller sizes. They are suitable for common users. Among the six Ethernet switches we have tested, EDIMAX ES-5800R and LeaPComm6004 switch is not manageable switch, Accton es00008 and creative company Thinker3800 switch are network tube type

The Windows Server 2012/r2 Hyper-V Virtual Switch (vSwitch) introduces a number of user-requested features to enable tenant isolation, communication shaping, preventing malicious virtual machines, and more easily troubleshooting problems. This guide focuses on improvements in open scalability and manageability of non-Microsoft extensions. You can write non-Microsoft extensions to emulate the full functionality of hardware-based switches and to support
Three-layer switch compared to routers in a large LAN, this function is perfect, to master the three-layer switch is very helpful, but now some manufacturers of switches can also directly connect the Internet to provide router capabilities.
Comparison of three-layer switch and router
In order to meet the challenge of deepening the network application, the netwo
Introduction: Android Custom view for beginners and even work for a few years of programmers are very afraid, but also is the Android advanced learning, peacetime projects often have some harsh requirements, we can find a variety of GitHub on the effect, can use, You can't use your own time to change it. However, with the work experience and the nature of the work, it is increasingly felt that customizing the view is the time to take some effort to study.
One, after these two days of efforts, I
Switch does not need to go through the initial configuration, direct access to the network can work properly, this is the development trend of the switch now. But this is a relatively unprofessional approach. Because if the relevant initialization configuration is not done, it is very unfavorable for the subsequent error and maintenance. If the name of the switch

Intrusion detection systems (intrusion detection system, IDS) are the hot security products in the past two years, which play a role in the network security system can detect intrusion behavior and alarm. The intrusion behavior described here covers a wide range of activities, including not only hacker attacks, but also various network anomalies, such as the leakage of internal network confidential information and the illegal use of network resources, and so on.
In orde
, also greatly stimulated the vast number of manufacturers in the network critical equipment, so that in a very short period of time from the traditional second-tier switches, to technologically advanced third-tier switches, and then to the recent launch of the fourth layer, or even the seventh layer of the product of the gratifying situation.
Layer Fourth switch is different when the third layer switch is
First, the switch types are divided into low-end (SOHO-level) and high-end (enterprise-level ). An important difference between the two is the low-end switch. Each physical port is a logical port, while the high-end switch binds multiple physical ports into one logical port for configuration. In a cisco Network, the switch
The gigabit router switch technology must meet several requirements without blocking. The gigabit router switch technology provides a detailed description of the requirements for non-blocking. This is a common problem. But how can we learn the Gigabit route switch technology more precisely to facilitate our work?
Standard for selection of Route switches and five
With the increasing popularity of wireless networks, more and more institutions and enterprises are beginning to implement wireless LAN. Up to now, wireless LAN is generally composed of clients connected to the access point, and the Access Point must provide security, management, and other intelligence required to control the wireless part of the network. The problem is that managing multiple access points is an insurmountable situation for networks that may involve hundreds or thousands of acce
The use of wireless switches brings more convenience to enterprises. Its performance makes enterprise network management easier and more systematic. Let me study the three advantages of wireless switches. I hope this article will help you understand the features of the wireless switch.
The problem is that managing multiple access points is an insurmountable situation for networks that may involve hundreds or thousands of access points. In this case, a
What kind of open computing switch can you buy?
Whether you love it or hate it, the Open Computing Project (OCP) has made waves in the hardware world of the data center. When Facebook decided to develop and produce its own high-performance data center switch, it reminded network giants Cisco and Hewlett-Packard to let them know that the present is a changing era.
Two years ago, Facebook announced the devel
Quickly set the loading process of the quick switch on the panel, including the process of loading and clicking events such as icons, and the main process of creating a shortcut switch (to add a lock screen switch for example). The Android version discussed in this article is 5.1.

Switch Summary:The similarities between the switch and the bridge are as follows:1. Bridges and switches are linked to LAN segments.2. Bridges and switches use the MAC Address table to identify the network segment to which the data frame is destined.3. Bridges and switches help reduce network traffic.Switch-to-bridge is a great advantage to eliminate network congestion:1. Dedicated inter-device communicatio

Beginner: I learned about the basic features of a layer-3 Switch. Some time ago, my colleagues asked me questions about the basic features of the layer-3 Switch. At that time, I did not give a positive answer, I was also the first to have a problem with the basic features of a layer-3 Switch. In the following days, I checked the relevant information and was satis
