Principles of Network Switches
A network switch is a device that expands a network and provides more connection ports for connecting more computers in a subnetwork. With the development of the communication industry and the advancement of national economic informatization, the network switch market is showing a steady upward trend. It has the characteristics of high performance to price ratio, high flexibility, relative simplicity, and easy implementation. Industrial DTU
A network switch is a device that expands a network and provides more connection ports for connecting more computers in a subnetwork. With the development of the communication industry and the advancement of national economic informatization, the network switch market is showing a steady upward trend. It has the characteristics of high performance to price ratio, high flexibility, relative simplicity, and easy implementation. So, Ethernet technology has become the most important LAN networking technology today, and network switches have also become the most popular switches.
Ac Controller Router Principles
A router is a hardware device that connects two or more networks, serving as a gateway between networks. It is a specialized intelligent network device that reads the address in each packet and determines how to transmit it. It can understand different protocols, such as the Ethernet protocol used in a local area network and the TCP/IP protocol used in the Internet. In this way, routers can analyze the destination addresses of data packets sent from various types of networks, convert non TCP/IP network addresses into TCP/IP addresses, or vice versa; Then, according to the selected routing algorithm, each data packet is transmitted to the designated location along the optimal route. So routers can connect non TCP/IP networks to the Internet. Network Switches
What is the difference between a network switch and a router
A router is a device that connects various local and wide area networks in the Internet. It automatically selects and sets a route based on the channel situation, and sends signals in the best path in sequence. A network switch is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes accessing the switch, the most common being an Ethernet switch.
1. Working at different protocol layers
The network switch is the equipment of the data link layer, and some network switches can also realize the switching of the third layer. Routers can solve the problem of forwarding packets between heterogeneous networks, acting on the network layer. Compared to switches, routers have more powerful functions, but they are relatively slow and expensive. At the same time, three-layer switches have both the ability to forward packets at line speed and the excellent control function of routers, making them widely used.
2. Acting on different types of networks
Network switches are generally used for LAN WAN connections and internal network communication. Routers are used to connect between WAN and WAN, enabling communication between different networks. The switch utilizes switching technology to achieve fast transmission of data within the network by using MAC addresses. Simultaneously supporting various technologies such as security control and IP telephony.
