Gigabit Ethernet is a technology built on the basis of Ethernet standards. Gigabit Ethernet and heavily used Ethernet are fully compatible with Fast Ethernet and take advantage of all the technical specifications set out in the original Ethernet standard, including the CSMA/CD protocol, Ethernet frame, Full-duplex, flow control, and the management objects defined in the IEEE 802.3 standard. As an integral p

As a key school in Jiangxi Province, Cangnan Middle School was listed as a pilot school in the province by the Ministry of Education of Jiangxi Province, and planned to promote the network application of the school gradually to the whole province. The new campus, an area of more than 20,000 square meters. Cangnan Middle School Initial Network application basic requirements are able to meet the campus

Analyzes the security firewall built in the gigabit network switch, and implements the Gigabit line rate switching by using the proxy plug-in of the gigabit network switch application service. The built-in security firewall will also be a highlight of

When QEMU is started, the tap virtual network card and qemutap virtual network card are inserted. 1. Use the brctl command to create a virtual bridge br0 Brctl addbr br0 Ifconfig br0 up // the preceding two commands are executed separately, leading to network disconnection. 2. Bind the virtual bridge br0 to the p

TUN/TAP Virtual Network device provides the ability to send and receive network packets for user-space programs. He can be either a point-to-point device (TUN) or an Ethernet device (TAP). In fact, not only does Linux support TUN/TAP virtual

There are many areas worth learning about routing switches. Here we mainly introduce the practical application of gigabit routing switches in the domain network. Gigabit routing switches are mainly used in small and medium enterprises, but because they are expensive, therefore, you must make a comprehensive selection. For the reliability of a

Http://www.cnblogs.com/heidsoft/p/3525646.html?utm_source=tuicoolutm_medium=referral The Tun/tap driver realizes the function of the virtual NIC, Tun means the virtual point-to-point device, tap means the virtual Ethernet device, the two devices implement different encapsulation for the network package. With Tun/tap Dr

GE Ethernet switches are one of the most widely used switches in enterprises. Here we mainly analyze how GE Ethernet switches and ATM affect network performance. The selection of the main networking technology directly affects the network system performance and future expansion and upgrade. The selection should be fully demonstrated and carefully conducted. In the previous years of

Basic tutorial on using TUN/TAP virtual network card in CentOS In computer networks, TUN and TAP are virtual network devices in the operating system kernel. Different from devices implemented by hardware network boards, all these virtual

In the computer network, Tun and tap are virtual network devices in the operating system kernel. Different from the common hardware network card implementation of the device, these virtual network devices are all software implementation, and running on the operating system o

There are many points worth learning about the gigabit network management switch. Here we mainly introduce the basic principles of the gigabit network management switch. NETEGAR's Fast Ethernet and 1-gigabit Network Management Swi

It should be said that gigabit network switches have become the first choice for medium and large enterprises. A high-performance switch not only improves the speed of devices, but also adds a lot of functions. The new intelligence of GE switches makes Ge switches an indispensable choice. The following describes the structure of a gigabit

Gigabit Network is a fast Ethernet, its data transmission rate of 1Gbps, still using CSMA/CD access control mechanism and with the existing Ethernet compatibility, with the support of cabling system, can make the original Fast Ethernet smooth upgrade and can fully protect the user's original investment. At present, gigabit ne
