without competing with other devices. When node A sends data to node D, node B can send data to node C at the same time, and the two transports all have their own virtual connection with all the bandwidth of the network. If this is a 10Mbps Ethernet switch, then the total flow of the switch is equal to 2x10mbps=20mbps, and the total flow of a hub will not exceed 10Mbps when using the

10Mbps, 100Mbps, 1Gbps to 10Gbps, and the Ethernet technology standard for 100Gbpsis under study. It can cover the core layer of the broadband Metropolitan Network, the aggregation layer to the access layer of the various requirements, so Ethernet technology in the broadband metropolitan area Network to provideThe potential benefits of multiple end-to-end scenarios.3) If a broadband metropolitan area network can use the same technology at all levels,

crosstalk between data transmission lines. As a result of the above reasons, as long as the actual circuit using low-voltage differential signal (Voltage differential Signal, LVDS), the amplitude of 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 whe

Through the filtering and forwarding of the switch, it can effectively isolate the broadcast storm, reduce the occurrence of the mistake packet and the error packet, avoid the sharing conflict.The switch can transm

higher the speed of the switch, the faster the data transmission of the home network is? In fact, the home network data transmission speed, in addition to the switch-related, but also related to other 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

Ethernet network technology, its basic network design and technology implementation is relatively simple 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 requirem

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 curren

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, a

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

representation.　　BYTE: "Byte", a byte is 8 bits. 3, Mbps (million bits per second Mbit/s) represents 1,000,000 bits per second. This abbreviation is used to describe the data transfer speed.　　For example: 4mbps= transmits 4M bits per second.　　The unit of data transfer rate, the letter B (bit) is the bit and the letter B (Byte) is a byte. 4. Throughput vs. Bandwidth: Throughput and bandwidth are easy to mix, and the units are Mbps. First let's look at the two corresponding English, throughput: t

units are Mbps. Let's look at the corresponding English, throughput: throughput; Bandwidth: Max net bitrate. When discussing the bandwidth of a communication link, it usually refers to the number of bits per second that can be transmitted on the link, depending on the link clock rate and the channel encoding in the computer network, also known as the line speed. It can be said that the bandwidth of Ethernet is 10Mbps. However, you need to differentia

frame when the frame transmitted by host a transmits to the first moment of B. Thus, when A's frame reaches B, b detects a conflict and sends a conflict signal. If A's frame has already been sent before the conflict signal in B is transmitted to a, then a will not detect the conflict and mistakenly think it has been sent successfully. Because the signal propagation is time-delay, it also takes a while to detect the conflict. This is also why there must be a minimum frame length limit.by standar
