Advantages of Using Core Switches and How to Select

The core switch is not a type of switch, but the switch placed on the core layer (called the network backbone) is called the core switch. The main function of the core switch is to complete the data exchange. Since it is in the core layer, the first goal is to process data fast enough.

Core switches should all adopt modular structure, have a considerable number of slots, and have strong network expansion capability. The modular structure has stronger performance, greater flexibility and scalability. It can select different numbers, different rates and different interface types of modules according to the actual or future needs to adapt to the ever-changing network requirements.

We rarely need to use core switches in the home. Generally, we need to use this kind of equipment after a certain number of computers have reached. It has a certain network expansion ability and can connect multiple computers to work. What are the advantages of using core switches?

1. High capacity

Although ordinary switches can meet the requirements of interconnection, there is still a gap in the identification and control of services, which can not ensure the continuity of services. The core Industrial Switches have high capacity, which can meet the needs of data centers, and can work normally in the case of large volume of services.

2. Large cache

The ordinary switch uses the out-port cache mode. With the development of technology, the core switch switches to the distributed cache architecture, which can improve the memory of the device. Compared with the ordinary switch, the device cache capacity is relatively large. In the case of burst traffic, the large cache can also ensure that the network forwards zero packet loss.

3. Virtualization

The core switch can virtualize real data and convert it into resources that can be managed online. The virtualization of equipment mainly includes multi-virtual-one, one-virtual-multi technology, multi-virtual-multi technology and other technologies. Through this technology, multiple network devices can be managed uniformly, and businesses on one device can also be operated independently, achieving the effect of reducing costs and improving utilization.

The above are the advantages of using the core industrial switch. In case of network failure, the equipment can ensure the reliability and integrity of data transmission through two-way data flow, and can achieve network self-healing. The core switch has strong scalability, supports multiple interfaces, and realizes bus network. In addition, it has an automatic alarm function inside, and can notify relevant personnel for maintenance in time after failure, It is convenient for us to manage and maintain remotely. After understanding the advantages of core switches, how should we choose?

1. Select a better core switch according to the switch structure

If you want to choose a better core industrial switch, you should pay attention to the switching structure: one is to adopt a centralized switching system, such as placing a control engine module with very strong performance and function in the center, and setting a simple interface card on the interface module. All data is transferred to the center card through the backplane for processing, and then sent back by the backplane after processing. The advantage of this design idea is that it can help users reduce the network cost from the ports of each module; The disadvantage is that in the case of low port efficiency of network data, all data exchange depends on the data processing board capacity of the core board. With the increase of the number of boards, the performance of the entire switch shows a downward trend, that is, the number of ports in the chassis is inversely proportional to the performance.

2. Select a better core switch according to compatibility

When we look at the core industrial switch, we have to pay attention to the compatibility: the industrial Ethernet switch and other components of industrial Ethernet should be able to use the standard TCP/IP protocol for communication. In any case, there should be no incompatibility between industrial Ethernet switches and commercial Ethernet devices. Corresponding to different industrial fieldbus solutions, industrial Ethernet equipment should have corresponding capabilities and compatibility.

At present, there are many businesses specialized in selling core industrial switches in the market. Consumers only need to consider the above factors and combine their actual needs to make purchase. It is recommended that consumers go to the stores of reliable core industrial switch manufacturers to purchase.
