Generic Internet cafe optical fiber switch solution perfect Manual

The LAN optical fiber switch solution can greatly improve the overall network performance of Internet cafes, especially in non-disk Internet cafes. The development of the Internet cafe industry has gone through countless leaps and bounds, no matter in the initial kitten age or in the present era of optical fiber access, each successful "transformation" has no influence on the impetus brought about by the emergence of new technologies and solutions. The emergence of fiber optic solutions for Internet cafes will undoubtedly bring a spring breeze to the entire Internet cafe industry. Compared with the current network exchange solution that uses twisted pair wires as the backbone transmission medium, the optical fiber switch solution will undoubtedly leave it behind.

I believe that with the help of the fiber switch solution, the entire Internet cafe industry can grow more stable, efficient, and fast! Optical fiber is generally made from SiO2 Z SiO2) by special pulling process. It no longer uses electronic signals to transmit data, but uses optical pulse to transmit signals. It is such a special material that gives it incomparable advantages over cables:

High bandwidth and high transmission capacity: because the carrier is light in the optical fiber transmission system and the optical frequency is high, the bandwidth and transmission capacity are high.

Strong anti-electromagnetic interference: Because the optical fiber transmits a beam, it is highly resistant to electromagnetic interference. Even if exposed to V or even v strong electromagnetic interference, it will not be affected.

Low signal loss: at present, the transmission signal loss of optical fiber is 0.2dB/km, which is close to the theoretical limit of optical fiber transmission.

Long Transmission Distance: optical fiber transmission distance can easily reach more than 550 meters, and copper cables have distance requirements. We all know that cables fully comply with cat5 or cat6 standards, with 150 M theoretical transmission of 100 M and M theoretical transmission of M.

We only need to solve the transmission medium from the server to the switch, as well as from the master switch to the access switch. The network speed and smoothness can be improved! Many people are still discussing how to set the cache, how to configure the server, the best brand of software XX, but ignore the most important thing that affects performance, that is, your Lan! Internet cafes, especially diskless Internet cafes, and LAN optical fiber switch solutions are very necessary. The following reasons are the best way to persuade everyone!

With the increase in disk performance, the bottleneck of the current server performance does not come from the disk array. Needless to say, SAS, ES, SSD will also become mainstream in the future, and the memory price is cabbage price. The CPU gradually changes from 4-core to 8-core... What do you think is the server bottleneck? With the improvement of diskless or diskless technology, software systems gradually rely on caching instead of array performance. The bottleneck is not the configuration of other parts of the server, but the local network. It is not just the Internet. With the increase of client configuration, the customer's wide application, as well as a large number of 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 entire Internet cafe. It also supports ARP security, port VLAN, and 802.1Q VLAN. It supports port mirroring, port aggregation, QOS, and other functions to meet different network application requirements.

2. Eight SFP fiber ports of the central switch can support two diskless servers and six access switches. They can be used for networks of about 120 to 150 units. Eight independent electrical ports can be connected to routers, toll collectors, and other servers.

3. The access layer switch uses the RHS4226GS all-gigabit smart monitoring switch, which provides 24 10/100/1000Base-T ports and 2 Gigabit SFP multiplexing ports with 48 Gbps board bandwidth, it can fully meet the network performance requirements of the entire Internet cafe.

4. RHS4226GS supports port/IP/MAC one-click binding. In the PC access layer port, it defends against all kinds of ARP viruses, effectively alleviating the ARP processing pressure on the switch and Gateway Router.

5. RHS4226GS also supports the port aggregation function. The port aggregation function is used on the main route or server with high traffic, which can increase the network bandwidth to ensure the smooth flow of all types of data. In addition, dual-line is equivalent to dual-line insurance, which greatly reduces the chance of failure when a single-line road appears.

6. The RHS4000 series switches fully support the integrated management system. For more information about the functions, see references.
