How important is the switching chip of an Ethernet switch?

What is an industrial Ethernet switch? Ethernet switch is a common network device, and industrial Ethernet switch is an Ethernet switch with industrial-grade characteristics. It plays a vital role in rail transit, intelligent manufacturing, smart mines, and industrial automation control systems. effect. With the continuous improvement of industrial automation, the requirements for industrial Ethernet switches are becoming higher and higher. This article will introduce in detail the principles, advantages, characteristics, applications and future development trends of industrial Ethernet switches.

The switching module, control module, and interface module constitute the switch hardware module structure. The switching module plays a decisive factor in data storage and forwarding switching. As one of the core chips of the switch, the switching chip determines the performance of the switch and is the most critical chip in network switch products. What speed interface does the switch support? How many interfaces does it support? How much performance and what functions are supported are basically determined by the switching chip.

The main function of the switch is to provide high-performance and low-latency switching within the subnet, and the high-performance switching function is mainly completed by the switching chip. At the same time, due to the large number of deployment nodes and large scale of switches, switches need to have lower power consumption and lower costs, which puts forward higher requirements for the power consumption and cost of switching chips.

Switch technology originated in the United States and is now widely used around the world. The core competitiveness of an Ethernet switch depends on the capability of its forwarding chip. So what are the switch switching chips? Currently, imported chip manufacturers include Cisco, Broadcom, Marvell, and Fulcum. The main domestic switching chip manufacturers include: Shengke, Nanfei Micro, Wuxin, etc. The main players in domestic processor chips include: Loongson, Zhaoxin, Feiteng, Haiguang, Shenwei and Huawei.
