At present, China's route switch equipment is developing very rapidly, and it is also more important in the development of the network, it also promotes the upgrade of routing technology. Traditional route switches are mainly used for Fast Packet forwarding, with emphasis on forwarding performance. With the wide interconnection of LAN and the openness of TCP/IP protocol, network security becomes a prominent

1. with the development of communication technology, the application of digital networks is gradually popularized, and IP Address resources are becoming increasingly scarce. Due to the traditional management of devices, the network management of each network device occupies a public ip address, which not only occupies a large amount of ip resources, but also requ

Layers of network equipment: network devices have repeaters, bridges, routers, gateways, and so on. Repeater (Repeater) repeater is the simplest device for LAN interconnection, which works at the physical layer of the OSI architecture, receives and recognizes network signals, and then regenerates the signals and sends

Abstract: virtual machines can generate several virtual network device types, such as e1000, rtl8139, and virtio, which are purely virtualized. What is the efficiency of Virtual Machine Communication when different network devices are loaded? This document records the test process and results. Introduction KVM virtual machines can generate several virtual

Do Zabbix monitoring test has been carried out for some time, the more testing found Zabbix strong, today began to increase the network equipment monitoring test, test results and cacti contrast, there is a great upgrade ready to abandon the former.Because network devices have no way to install proxy clients, the monitoring network uses the SNMP protocol1.

router devices bundled together. It can provide dual-SSID parameter settings, wireless Internet users can configure each AP function separately. Using this device, wireless Internet users can easily build two simple and economical Wireless LAN networks. Obviously, to build A wireless dual-network that meets both the Internet access requirements of Department A and the Internet access requirements of depart

The exclusive pseudonym is also large, the general name of the game.1, first: according to their own needs in the work, for the convenience of opening the network adapter, enter the command line to open the network connection: Ncpa.cpl. Main purpose to view the current network connection, modify the network IP address

, shape and hub is no different, is a communication system in the automatic completion of information exchange function of the device, the use and hub is also connected to the network, but it has a more powerful than the hub function. Switches are also called switched hubs, by regenerating the information and forwarding it internally to the specified port, it has an automatic addressing capability and a sw

overall power consumption of the device. An iOS device connected to a Wi-Fi network uses that connection for all data requests in the background, such as periodic mail checks or push notifications. Because the radio will be used, the use of Bluetooth radios will actually increase power consumption.All communications made through the game kit session are unencryp

assume that the traffic remains in the peak state. If this is not the case, when the processing task increases, your speech signal quality will decrease as your plan is not prepared. Another important thing is to check the cache space and discarded packets of your electronic devices. A vswitch can discard data packets. When the cache is too full, the switch will discard some data packets and request the sender to resend them. This function is not ideal for voice communication. Although you can

I. BACKGROUNDA virtual machine (VM1) was created with VMware, and another virtual machine (VM2) was created by copying it. Set the network card on the second virtual machine as a fixed IP, when using service network restart to restart the network error, eth0 can not find.Second, the reasonBecause the physical address of any two NICs cannot be the same, the physic

KVM in I/O virtualization, the traditional way is to use QEMU pure software to simulate I/O devices, including frequently used network card devices. This time we focus on QEMU's full virtualization solution for network device virtualization. This topic is fully described in terms of three components, including: 1. The establishment of front-end
