-3 bandwidth efficiency of 4 bits per hertz, so the frequency width is 125MHz. This is well limited to the next and Psnext ranges of category six cabling, so crosstalk cancellation is unnecessary. The current level of semiconductor technology does not use the back-ripple crosstalk cancellation device will reduce at least 50% of the overall complexity of the 1000BASE-TX design (compared with the current 1000base-t design). The grid coding technology may also need to be improved to ensure complian

Two stack methods can be used: the chrysanthemum Link Method (providing 1g bandwidth) or the point-to-point method (providing 2G bandwidth ).C. Both methods can be used for backup.D. The Chrysanthemum Link Method supports stacking of up to 9 switches, and the point-to-point method supports up to 8 switches.2. is redundant backup supported when the Catalyst 3550 XL series switches are stac

To reduce the time to market, the MLT-3 encoding method used by 100Base-TX will be selected, and the bandwidth efficiency of the MLT-3 is 4 bits per Hz, so the bandwidth is 125 MHz. This well limits the cat6 cabling to the NEXT and PSNEXT ranges, so crosstalk cancellation is unnecessary.

From the perspective of current semiconductor technology, the absence of ECHO and Crosstalk cancellation devices will reduce at least 50% of the overall complexity of the 1000Base-TX design (compared with the current 1000Base-T design ). By extension, if the data ratio increases from 600 Mbps to Mbps per pair, this design can be used in a

recently, the bandwidth concept and calculation of PCIe are somewhat blurred, and most of the online search data is a mold, This is calculated by the following formula:Parallel bus bandwidth (MB/s) = parallel bus clock frequency (MHz) * Parallel bus bit width (BIT/8 = B) * Transmission of several sets of data per clock (cycle)In particular, after the calculation is not very easy to understand, and then after consulting the information, the following understanding of "personal humble opinion, Wel

Cable TV Network (Cable Modem) The cable television network is suitable for the whole country, many places provide the cable modem access Internet way, the rate can reach more than Mbps. However, the cable modem is a total-Heng bandwidth, and in a certain period of time (busy) there will be a decline in rate phenomenon. 5. Optical fiber access (FDDI) The high-speed metropolitan area network built with

, and intelligent hubs. The passive hub is only responsible for connecting multiple segments of media without any signal processing. Each media segment can be expanded to only half of the maximum valid distance. An active hub is similar to a passive hub, but it has the ability to regenerate and enlarge transmission signals to expand the length of the media. In addition to the functions of the active hub, the smart hub can also integrate some functions of the network into the hub, such as network

In fact, Cisco does not take a special advantage in the low-end switch market, because 3Com, Dlink and other companies have better performance and price ratios. The 1900 vswitch is a typical low-end product for desktop computer access at the end of the network. It provides 12 or 24 10 M ports and 2 100 M ports.

The cost difference between single-mode fiber and multi-mode fiber is very high, but as the connector price drops and the termination method is simplified, single-mode fiber will become a more attractive option. Generally, the rated rate of multimode optical fiber is 500 Mbps per kilometer, and the rate of horizontal wiring is 5 Gbps per 100 meters. Mu

When using the bandwidth of the vswitch backboard, problems such as the bandwidth of the vswitch backboard frequently occur, as well as the bandwidth of the vswitch with line speed and related knowledge, here we will introduce the solutions to many problems related to the vswitch backboard bandwidth. We all know that the unit of the total data exchange capability of the vswitch's backboard bandwidth is

The UGS-7324RS has 15 Gbps non-blocking back-board bandwidth, in the layer-2 switch, the packet forwarding rate reaches the line speed value of Fast Ethernet; As a layer-3 switch, the packet forwarding rate reaches 6.6 Mpps, it provides a high-performance platform for

interface speed of a Gigabit Switch Router can reach 622 Mbps, Gbps or even 10 Gbps. This speed has long left the ATM switch behind, but the gigabit core router is generally used as the backbone of the enterprise network, in addition, the price is much higher than the average household router. Therefore, the general 10/100 M
