about 350mV can meet the requirements of near-distance transmission. Assuming that the load resistance is 100 kohm, when using LVDS transmission data, if the twisted pair length is 10m, the transmission rate can reach 400Mbps, when the cable length increases to 20m, the rate will be 100Mbps, and when the cable length is 100m, the rate can only reach 10Mbps around4.

network equipment, which requires everyone in the selection of switches, can not go to the one-sided pursuit of high-speed, but should pay attention to keep pace with other equipment matching. Due to the current mainstream LAN devices, the speed of their data transmission is generally in the 10Mbps, 100Mbps of these two levels, and such level of network technology has been very mature, so the speed of home switches as long as the two levels can be re

and mature, mainly including the structure of the campus wiring and Ethernet design and implementation. The following points should be paid attention to in the whole scheme design of physical network: Because this scheme uses the local area network Ethernet technology, the network wiring structure and the cable selection design should be formulated according to the Ethernet design requirements. The choice of Ethernet technology. can use Gigabit Gbps Ethernet, 100Mbps Ethernet,

computer is cloned to the WAN port of the router, as shown below. Solution to the general routing broadband dialing prompt "Server unresponsive" approach four, line suitability problem Possible reasons: Household network cable due to aging, poor quality or too long line, resulting in line attenuation too large. Workaround: Try to adjust the rate mode of the router WAN port. Login Router Management interface, click Advanced Settings >> network parameters >>wan port settings, Wan r

characteristics. The most commonly used in the network is the three types of lines and five types of lines, at present there are more than six types of lines. The third kind of twisted pair is commonly used as 10Mbps Ethernet data and voice transmission in LAN, which accords with the standard of IEEE802.3 10base-t. The fifth type twisted-pair line currently occupies the largest LAN market, the highest rate can reach 100Mbps, conforms to IEEE802.3 100

Setup method: Login Router management interface, click Network parameters >> Wan Port rate mode, choose 10Mbps half-duplex or 10Mbps full-duplex mode in the mode setting, click Save, as shown in the following image: Note: Some routers or some software versions do not support adjusting the WAN port rate mode, and you can try to

Replace the browser (using Firefox/firefox, Google/chrome, or other browsers) to try again, if still not online, try to change the computer to do a comparative test. Household network cable due to aging, poor quality or too long line, resulting in line attenuation is too large, resulting in a WAN port parameters, but not the Internet.

how much. First of all, our Web server uses Gigabit NIC (Gigabit NIC is the main server configuration, most server motherboards are integrated dual gigabit NIC, respectively for the external network card and intranet card), that is, the speed of 1000mbit/s, Then the 100MB file out of the network card when the delivery time: 800mb/1000mbps = 0.8s. Next, assuming that the Web server is directly connected to the Exchange node A in its cabinet, switch Node A has a 10MB exclusive bandwidth limit on

application of fiber to desktop. Expensive, installation and maintenance costs of high reasons, can not be widely promoted. At the same time, with the rapid development of the computer network of the office environment, the application of high number rate to the desktop is more and more common, and the LAN speed is shifted from 10Mbps to 100Mbps, and will soon develop to 1000Mbps. The wiring system that transmits data for the computer network, in th

Test with a wire detector, found that the transmission speed of this network can only be 10Mbps, there are serious quality problems, re-production of information points and replace the network cable after the problem is completely resolved. So for network cable These

Used to use routers and hubs in the network, and now many networks use switches, how to face the challenges of routing networks and switching technology?At present, the switch in the network market occupies a dominant position, the reason is: the first is the cost-efficient switch, followed by flexible structure, can be applied to the future changes in the flexible configuration.The figures best illustrate the problem. In a switch with a 100Mbps uplink, the cost of each
