POE Switch
Industrial switches have carrier-class performance characteristics and can withstand harsh working environments. The product series is rich, and the port configuration is flexible, which can meet the needs of various industrial fields. The product adopts wide temperature design, protection level is not less than IP30, supports standard and private ring network redundancy protocol
There are various classification methods for engineering materials. Engineering materials are generally divided into four categories according to chemical composition: metal materials, non-metal materials, polymer materials and composite materials.
The original meaning of textile is taken from the general name of spinning and weaving, but with the continuous development and improvement of the textile knowledge system and discipline system, especially the production of non-woven textile materials and three-dimensional composite weaving, it is not only the traditional manual spinning And weaving, also includes non-woven fabric technology, modern three-dimensional weaving technology, modern electrostatic nano-webbing technology and other apparel, industrial and decorative textiles.
Therefore, modern textile refers to a multi-scale structure processing technology of fibers or fiber assemblies. The ancient Chinese textile and printing and dyeing technology has a very long history. As early as the primitive society, in order to adapt to the climate change, the ancients had learned to use local materials, use natural resources as raw materials for textiles, printing and dyeing, and manufacture simple hand-woven tools.
Clothing, airbags, and curtain carpets in everyday life are the products of textile and printing technology.
The three-layer switch is a switch with partial router functions, and works at the third layer of the OSI network standard model: the network layer. The most important purpose of the layer 3 switch is to speed up the data exchange within the large local area network. The routing function also serves this purpose. It can do one routing and multiple forwarding.
Regular processes such as packet forwarding are implemented by hardware at high speed, while functions such as routing information update, routing table maintenance, routing calculation, and routing determination are implemented by software.
