The access switch is the most common switch. It directly contacts the external network and is most widely used, especially in general offices, small computer rooms, and business departments with more centralized business acceptance, multimedia production centers, and website management centers.
The main part of the network is called the core layer. The main purpose of the core layer is to provide optimized and reliable backbone transmission structure through high-speed forwarding communication. Therefore, the core layer switches should have higher reliability, performance and throughput.
Data center switches meet the needs of data center rack-level access switches, with small pluggable LC fiber uplinks, Link Aggregation Control Protocol, virtual LAN tags, storm control, and bandwidth control.
Industrial Ethernet switch, is the Ethernet switch used in the field of industrial control, due to the adoption of network standards, its openness, wide application, low price, and the use of transparent and unified TCP / IP protocol, Ethernet has become the main communication standard in the field of industrial control. Industrial switches have carrier-class performance characteristics and can withstand harsh working environments.
The convergence switch is the convergence point of multiple access layer switches. It must be able to handle all traffic from the access layer devices and provide the uplink to the core layer. Therefore, the convergence switch needs to be compared with the access layer switch with higher performance, fewer interfaces and higher exchange rate.
SMB switch is the small business switch, it is always used in small and medium-sized companies. This switch is relative to some large, high-end switches. SMB switches support common Layer 2 protocols, but the performance and number of interfaces are weak.
If you still don't know which switch to choose, the switch will be divided into two frequently used scenarios - enterprise use and home use.
Today's businesses demand and rely more on their network to carry out mission-critical business activities. Switches you choose must meet this growing need by providing fundamental network features such as VLANs, QoS, and IGMP Snooping that will help optimize the performance of business networks. Also, there are switches specially designed for small businesses (SMB) and branch offices. They are simple, flexible and secure switches ideal for out-of-the-wiring-closet and critical Internet of Things (IoT) deployments.
A network switch (also called an Ethernet switch) is a high-speed device that receives incoming data packets and redirects them to their destination on a local area network (LAN). In other words, a switch is the “brain” of a network. It connects all your smart devices and enables them to talk to each other no matter where they are located in your home. The switch also connects to a router and modem to access the internet. In comparison, the wireless counterpoint to an Ethernet switch is Wi-Fi.
