In this article, the editor introduces "how to choose a suitable switch" in detail. The content is detailed, the steps are clear, and the details are handled properly. I hope this article "how to choose a suitable switch" can help you solve your doubts. Let's follow the editor's ideas to learn new knowledge.

Enterprise switch

Enterprise switch belongs to a kind of high-end switch, which generally adopts modular structure, and can be used as the backbone of enterprise network to build high-speed local area network, so it is usually used at the top layer of enterprise network.

Enterprise-class switches can provide customization, priority queuing services and network security control, and can quickly adapt to the needs of data growth and change, so as to meet the needs of users. For networks with more requirements, enterprise-class switches can not only transmit massive data and control information, but also have the characteristics of hardware redundancy and software scalability to ensure the reliable operation of the network.

From its location, this kind of switch can clearly see that its own requirements are extraordinary, at least in terms of bandwidth, transmission rate and backplane capacity, which is much higher than that of ordinary switchs. therefore, enterprise-class switches are generally more than gigabit Ethernet switches. The ports used in enterprise-class switches are generally optical fiber interfaces, which is mainly to ensure the high transmission rate of the switch.

So what kind of switch can be called an enterprise switch? In fact, there is not a clear standard, but it is generally believed that if it is the backbone switch of an enterprise, the switch that can support more than 500 information points for large-scale enterprise applications is an enterprise switch.

The enterprise switch can also be connected to a large chassis. This chassis product usually supports many different types of components, such as Fast Ethernet and Ethernet repeaters, FDDI concentrators, token Ring MAU and routers. Enterprise switches are very useful in building enterprise-level networks, especially for those that need to support some network technologies and previous systems. Chassis-based devices usually have very strong management characteristics, so they are very suitable for the environment of enterprise networks.

Campus network switch

The application of campus network switch is relatively less, mainly used in larger networks, and generally used as the backbone switch of the network. This kind of switch has the ability of fast data exchange and full duplex, can provide intelligent features such as fault tolerance, and supports many functions such as expansion options and virtual local area network (VLAN) in layer 3 switching.

This kind of switch is usually used in the decentralized campus network, but it does not have to be used in the campus network, but only means that it is mainly used in the larger network with scattered physical distance. Because the campus network is scattered and the transmission distance is long, in the backbone network segment, this kind of switch usually uses optical fiber or coaxial cable as the transmission medium. Of course, the switch also needs to provide SC optical fiber port and BNC or AUI coaxial cable interface.

Departmental switch

Departmental switches are switches for departmental networks. This kind of switch can be fixed configuration or modular configuration, generally with optical fiber interface in addition to the commonly used RJ-45 twisted pair interface. The departmental switch generally has outstanding intelligent characteristics, supports port-based VLAN (virtual local area network), can realize port management, can adopt full-duplex or half-duplex transmission mode arbitrarily, can control flow, has the function of network management, and can configure, monitor and test the switch through the serial port of PC or through the network.

If it is a backbone switch, it is generally considered that a switch that supports a medium-sized enterprise with less than 300 information points is a departmental switch.

Workgroup switch

Workgroup switch is an ideal alternative to traditional hubs, which is generally fixed configuration and equipped with a certain number of 10Base-T or 100Base-TX Ethernet ports. The switch makes a relatively simple decision to forward information according to the MAC address in each packet, which generally does not take into account the deeper other information hidden in the packet. Different from the hub, the forwarding delay of the switch is very small, and the operation is close to the performance of a single local area network, which far exceeds the forwarding performance between ordinary bridged internetworks.

The workgroup switch generally does not have the function of network management, and if it is a backbone switch, it is generally considered that the switch that supports less than 100 information points is a working group-level switch.

Desktop switch

Desktop switch, which is the most common low-end switch, is different from other switches in that it supports few MAC addresses per port and usually has fewer ports (less than 12 ports, but not absolutely). It only has the most basic switch characteristics, and of course the price is the cheapest.

Although this kind of switch is the lowest in the whole switch, it still has the general advantages of the switch compared with the hub, and there are many application environments that only need these basic performance, so it is still widely used. It is mainly used in office desktops of small or medium-sized enterprises. In terms of transmission speed, most desktop switches provide multiple ports with 10/100Mbps adaptive ability.
