One problem with the status quo
After years of change and development, Internet network has undergone enormous changes: networking equipment into a switch from the HUB, access way from the cat into a fiber-optic Internet access, speed from Shizhao to Fast, to the Gigabit ... ... every time change, because the process of rapid development of Internet cafes industry emerging new needs, leading to the original plan caused not qualified. D-link in each change, both for the performance of Internet cafes has brought new technology and new programs. Recently, to Internet cafes disk technology for emerging network applications on behalf of the network transmission speed due to a bottleneck problem, D-Link once again to a forward-looking vision, make optical networking solutions.
Second, fiber bars is the trend
The so-called diskless Internet cafes, is to use the underlying technology on the server through the network simulation into a hard disk image file, and from its start, while the client without having to install the hard disk, the benefits of doing so is cost savings, ease of maintenance. But diskless Internet cafes because the moment the client started to transfer vast amounts of data, causing a lot of pressure on the network distributors, so disk speed network technology and the stability have put forward higher requirements.
Technically, the gigabit network to satisfy the needs of diskless, and now almost all Internet cafes have been upgraded to gigabit, why is there still a bottleneck network transmission phenomenon? After research, found that most of the existing Internet cafes are all twisted pair networks as the main transmission medium, and the following common problems:
1. Cafes poor construction technology wiring, cable laying at random, there is no concept of structured cabling;
2. Copper cabling products on the market of varying quality, most Internet cafes to choose as the basis for cheap, but cheaper product counterfeiting is serious, leading to a substantial decline in transmission performance;
3. The characteristics of the copper transmission media do not know enough, do not do a very good anti-interference measures, strong electrical interference seriously.
It is for these reasons, resulting in greatly reduced speed Gigabit network.
D-Link network equipment solutions not only have experience, but also a professional manufacturer of connectivity products, this set of experience in many fields in one's overall quality, so they are keen to realize - fiber optic solutions, there is no the best partner site cafes.
From a technical point of view, optical fiber transmission bandwidth than copper hundreds of times larger, and the ability of optical interference, transmission distance is long; from a cost point of view, the current price of one meter fiber than a meter long noodles still cheaper and since 2000, copper prices have gone up 100 times. It is increasingly obvious optical advantage, it is considered a new generation of information transmission medium of choice, several countries have already achieved the fiber to the home, our country in the next three years, fiber-optic broadband network construction investment will be more than 150 billion yuan , add to more than 50 million broadband users. In this trend, the fiber network solutions is already the preferred Internet cafes.
3, D-link fiber optic solutions help Beijing Internet cafe Internet cafe and Friends
(A) solution
Friends of Beijing has a number of Internet cafes is a senior Internet cafe Internet cafe operators of Internet cafes offering diskless, with 260 PC, export bandwidth fiber-optic telecommunications links 30M. As the relatively large number of Internet cafes PC has selected the diskless network, the network transmission speed is high, so D-link the user is using Internet cafes backbone fiber network. Because the transmission bottleneck disk access switch to the core switches in the backbone and the server to switch the lines, it is proposed that these places use fiber, while the access switch to the desktop using copper.

Friends of Beijing Internet cafe network equipment list:
Device Type | Equipment Type |
All Gigabit Router Internet cafes | DI-4700 |
Gigabit core optical switches | DGS-3100-24TG |
Gigabit Access Switches | DIS-2024TG |
Optical Module | Optical Module |
Fiber Optic Cable | Fiber Optic Cable |
(B) D-Link fiber-optic Internet cafes program features:
The program's biggest advantages is the main way to access the entire fiber topology. This topology cafes and diskless systems give way to a more stable and efficient network environment.
DI-4700 is a full Gigabit of Internet cafes dedicated router, in this Internet cafe which served as an important gateway role, but also on the PC, Internet cafes were all high-level flow control and connection limits, and optimize the network game speed. Not only that, it's network of Internet cafes to monitor the police, effective defense ARP attack and many other common viruses. While in the defense do the problems quickly locate! Internet cafes can be said to forestall chaos and dignity!
DGS-3100-24TG is a high performance full-Gigabit fiber-optic network switches. It is equipped with 16 optical SFP ports and 8 Gigabit copper port. This will not only meet the fiber-optic backbone access also allows non-optical Gigabit NIC server connection while doing link aggregation to ensure server stability. In terms of security it supports triple binding, and the port engine speed limit and safety protection and other advanced technologies. Internet cafes in meeting the core access, and port mirroring while further ensuring the safety bars in the local area network, can be said to be comprehensive!
DIS-2024TG is a special access switches, Gigabit Internet cafes. It has 24 Gigabit ports and two fiber optic power ports, while satisfying the client's Gigabit backbone optical fiber access needs and requirements of the cascade. 48G high-back and 36Mpps ensure high forwarding rate high forward speed of the network load. As a gigabit-class access switch can be described as its capability!

Friends of Internet cafes Photos
Friends of Internet cafes have opened in Beijing, the network is stable, fast-paced, already has a number of fixed users. The D-Link in the proposed fiber-optic Internet cafes, the pace of progress did not stop for more extensive application of Internet cafes on the transmission speed increasing demands, D-Link Gigabit network technologies have been introduced in the feasibility analysis of Internet cafes I believe that in the near future, D-Link Internet cafe industry will bring it higher, faster, stronger solution!
