The solution for handling 300 or less Ge Fiber switches in Internet cafes is analyzed. The solution for Internet cafes with 150 computers is different from that for Internet cafes with 200 computers. The solution for medium-scale Internet cafes is provided below. Internet cafe owners can check their seats and find their own methods. About 150 Internet cafes The network center uses the RHS4616GMS fully-managed Gigabit Optical Fiber switch. It provides 8 Gigabit

local data reads and writes, P2P, or even Intranet DoS .... Is it still unable to explain the bottleneck affecting the performance of Internet cafes? About 150 Optical Fiber Switches 1. The network center uses the RHS4616GMS full-gigabit managed optical fiber switch. It provides 8 Gigabit SFP Optical Fiber ports, 8 independent 10/100/1000Base-T ports, and 48 Gbps backboard bandwidth, it can fully meet the network performance requirements of the entir

With 500 computers, the Gigabit Optical Fiber switch solution is required. Internet cafes need to support port mirroring, port aggregation, QOS, and other functions of the Gigabit Optical Fiber switch, to meet different network application requirements. Internet cafes with a large number of computers should also have other solutions. 300-about 500 Internet cafes The network center uses two RHS4624GMS fully Gigabit managed Ge Optical Fiber switches for 10 Gigabit cascade. It can provide 32 Gigabi

managed Internet cafe optical fiber switch. It provides 8 Gigabit SFP Optical Fiber ports, 8 independent 10/100/1000Base-T ports, and 48 Gbps backboard bandwidth, it can fully meet the network performance requirements of the entire Internet cafe. It also supports ARP security, port VLAN, and 802.1 QVLAN, Port Mirroring, port aggregation, QOS, and other functions to meet different network application requirements. 2. Eight

Optical fiber is generally made from Z (SiO2) after special pulling process. It no longer uses electronic signals to transmit data, but uses optical pulse to transmit signals, it features high bandwidth, large transmission capacity, low signal loss, and long transmission distance. Therefore, the emergence of the Internet cafe Optical Fiber solution will undoubtedly bring a spring breeze to the entire Internet cafe. The development of the Internet cafe industry has gone through countless leaps an

configuration and wiring approach look the same. The color coding of the TPU2 line helps to compare these photos. Three Google TPU2 cabinets Google shows the top view of the TPU2 circuit board and the proximity of the front panel interface of the circuit board. All 4 quadrants of the TPU2 circuit board share the same power distribution system. We believe that the 4 TPU2 circuit board quadrants also share the same network connection through a simple network switch. It seems that each circuit boa
