Want to know layer 2 network switch? we have a huge selection of layer 2 network switch information on alibabacloud.com
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 netw
. It consists of the actual interface between the computer and the network medium, can define electrical signals, symbols, line status and clock requirements, data encoding and data transmission connector. Such as the most commonly used RS-232 specification, 10base-t Manchester code and RJ-45 belongs to the first layer. All layers higher than the physical layer c
Compared with the layer-3 switch, the layer-4 switch has a good improvement in its functions and features. Here we have explained the basic knowledge of the layer-4 switch. The amount of transmitted audio, video, data, and other i
The layer-4 switch is quite common. So I studied the comprehensive application of the layer-4 switch and shared it with you here. I hope it will be useful to you. With the popularization of broadband and the deepening of various network applications, our local
future when accessing the public network. Private networks with private addresses when accessing the Internet, use address translation (NAT) to translate the private address into a common legal address. On the Internet, such addresses are not allowed to appear. All routers in the Internet are not forwarded to a datagram where the address is a private address. The common 192.168.1.2-192.168.1.99 is to manually configure the IP segment, from 192.168.1.

These statistics are particularly effective for examining the load of each application on the server, for example, you can view the system resources occupied by a service application. Conclusion: The layer-4 exchange technol

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

Experiment on single-arm routing using a layer-3 Switch In the real environment, sometimes the gateway is not necessarily enabled on the router, sometimes the single-arm routing function is not necessarily connected to the interface on the router, you can use a layer-3 switch, because the vswitch itself has a variety o
DES-3326 switch also provides the traffic control function, supports VLAN division, and provides redundant power interface. Comments: The Performance of the switch in the tens of thousands of layer-3 switches in the general performance, although this switch provides 24 10/100 Mbps adaptive RJ-45 port, but the support

is: it is a function, so it is not so much a hardware network device as a software network management system, in other words, it is a kind of network management and exchange equipment that focuses on software technology and supplemented by hardware technology. It decides that the transmission is not only based on the Layer
Intranet. It combines the advantages of layer-2 switches and layer-3 routers into a flexible solution to provide line rate performance at all levels. This integrated structure also introduces policy management attributes, which not only associate Layer 2 with
Three-tier switch has become one of the mainstream switch types in the market. Here we mainly introduce the advantages of using three-tier switch. This article will tell you that the three-tier switch has a high technical level, not only does it look beautiful, but it also looks beautiful! So what is the role of
With the development of China's routing industry and the wide application of L3 router switches, I have studied the benefits of choosing a l3 router switch. I will share with you here, I hope it will be useful to you. In addition to excellent performance, layer-3 route switches also have some features that traditional layer-2
