How to build a high-speed, stable, high-quality internet cafe?

Internet cafes are a special environment for network applications. They have various application types and have high requirements on network bandwidth, transmission quality, and network performance. As we can see, Internet users who come to Internet cafes have different needs and applications, nodes in Internet cafes often need to browse, chat, download, VOD, online games, and other operations at the same time and without interruption. The data traffic, especially the outbound traffic, is huge. These characteristics in Internet cafe applications determine the two commonalities of Internet cafe application requirements:

1. To meet customers' needs to transmit voice, video, and data on a broadband network at the same time, we must also fully consider the support for various new business data processing to ensure high-speed and smooth access to the Internet, big data traffic does not drop or stop. All of these are the requirements for system speed.

2. At the same time, the requirements for a wide range of special functions, both hot and cold applications, as well as high stability and reliability also determine to ensure uninterrupted and stable operation of the system for a long time, this is a severe requirement on system stability.

Therefore, how to build a high-quality network environment and set up a high-speed and stable Internet cafe application system to meet Internet Users' Requirements for Internet cafes has become the basis for the establishment of modern high-quality internet cafes.

Currently, high-speed Internet cafe solutions are generally designed based on a gigabit network structure. The core of this solution is an intelligent network switching system. In traditional internet cafe solutions, network devices only act as network interconnection and do not have smart functions such as Qos Control and multicast. However, the high scalability of the new core exchange system can meet the increasing network bandwidth needs of Internet users, it can also match various network services and real-time bandwidth in Internet cafes. In addition, while providing high-speed switching capabilities, the intelligent switching system can also properly and orderly control core host services and ensure the reliability provided by its hardware, it can lay a solid foundation for the stable operation of Internet cafes.

The intelligent network switching system is generally composed of several layer-3 speed switches using Gigabit 10-Gigabit Optical Fiber Technology and several level-2 Switches Based on Optical Fiber or copper cables. The layer-3 Switch provides high-speed Layer-3 switching capability, it provides powerful virtual stack functions to easily complete local high-speed data exchange in Internet cafes. It also supports IGMP and other multicast protocols to meet the requirements for concurrent processing of large-volume multimedia data such as videos. The 802.3ad protocol is used internally to implement link aggregation, so as to provide a fast switchover function to solve the network bottleneck caused by cascade between switches. The Rechargeable redundant power supply group of a layer-3 switch ensures uninterrupted network operation for a long time, the hardware-based wire speed forwarding capability enables the task of data packet routing to be executed by the dedicated ASIC on the switch, while greatly improving the performance, it has also become a powerful guarantee for the stability of network channels between Internet cafe nodes and shared servers.

The second-level switch device selects a universal switch group to provide a certain Gigabit Optical Fiber port and a high-density 10-Gigabit port. In the network access layer, the device can be connected to the above Gigabit backbone network and the nodes in the Internet cafe. The second-level switch device also provides bandwidth-sensitive functions such as VLAN and priority queue. In the Web-based interface configuration, any common Administrator, when the physical location of an area in the internet cafe changes, you only need to set the second-level switch, the network can be reorganized, and all customers in each region can use the network smoothly and stably.

From the above description, it is not difficult to find that the intelligent network switching system ensures a high-speed and stable full gigabit network: it uses a full Gigabit link to build a network, which can meet the needs of the current Internet cafe big data transmission, at the same time, the core switch provides hardware-level line rate forwarding. The task of data packet routing is completed by hardware, which not only produces an advantage over the traditional solution in terms of speed, but also makes the entire network more stable. At the same time, the intelligent network switching system is a core system with rich features: the core switch and the secondary network access device are integrated with multiple functions, enabling the intelligent network switching system to support access control and storm control, port Mirroring, power supply hot standby, and other key applications have become a powerful guarantee for stable and secure networks and uninterrupted operation for a long time. Therefore, the intelligent network switching system has become a powerful guarantee for the high performance and stability of Internet cafe applications, and has become the first step to establish high-quality internet cafes.
